Longterm review ttmountainbike.com/2021-polygon-siskiu-t8-long-term-review/
I notice with spacers in the rear suspension you have now dropped the pressure down to 160-165 psi and rebound 4 or 5 clicks. On the Fox website for this pressure they recommend 8 clicks which is significantly different to your 4 to 5 clicks - can you provide further information on your rebound setting? I am setting my new Siskiu T8 and I am very interested in your settings. Great videos by the way.
@@peterwilliamson1237 Thanks for tuning in. When it comes to rear suspension its very hard for companies like fox to give accurate rebound and compression settings as the leverage ratio among other things change from bike to bike so much as rear suspension designs vary. I found 4 to 5 for my weight worked well.
Again this is what works for me so might not work for you. I've settled on 167psi atm too, so slightly firmer than in the review
@@trailtalkmtb6603 Thanks for the response. T8 brand new on Saturday and yet to ride so it's nice to know your settings as I'm only 2 kg heavier but hit the trails less aggressively than you. I haven't got any volume spacers yet but I suppose the process is to first go with factory recommendation and tune from there. I'm very excited with my new bike and looking forward to playing with the suspension while I'm dialling it in - your videos and information a great help.
The paint job is incredible!
Thanks so much for making these videos my t8 just arrived yesterday and going to take it for a ride this weekend ! You really helped me with picking my new bike . Love the vids nice work mate !
Glad I could help!
Congratulations on getting engaged Phil 😊 Your channel continues to be one of my favourite for MTB content and your reviews on it helped me buy a 2019 Norco Fluid FS1, which has been a solid ride. Great video here and your polygon looks unbelievable with the changes.
Polygon says a 600ml bottle fits comfortably so just wanted to see if you got anything bigger in the water cage? Thanks
Thanks Brendan! Stoked to hear you are loving the Fluid! Currently working on the long-term review but I have been super busing lately and not having a house to film at easily is definitely hard! It is tight with the bottle, I'd say 600ml is the best you can fit
Just bought one looking forward to testing it out 🤗 I'm 5 foot 7, and weigh 85 kilo and got the medium sized bike, I'm just getting back into this so this bike is a good start
Lol I’m looking for a bike to start saving up for and this is one of the options!
Nice set up! I ended up grabbing one because of your previous videos. Make more riding videos! 😎
That's awesome, how are you liking it? I will do one after the next buyers guide :)
I just purchased this the other day, excited for when it arrives! I’m planning on running the Tannus tubeless inserts front and rear
Hope you enjoy it! I definitely tannus in the rear, don't feel like it's a necessity upfront unless you ride DH tracks a lot
@@trailtalkmtb6603 thank you I’ll keep that in mind, also your channel was a huge help in finding a reasonably priced bike!
@@trailtalkmtb6603 👽
What size tape did you use for the tubeless?
Just purchased this last week. When you upgraded the rotors is there a center lock or just the standard 6 bolts holding it on? Mine will be here in May and starting to gather some upgrades. Thanks for the great reviews on this bike and am looking forward to your next long term review of the T8.
Love to know your thoughts on the difference between the n7 and this bike and which you would prefer
Nice breakdown!! Can you please let me know what volume spacers you used for the suspension and are they hard to install? My T8 will be here in about a month and I really want to get the most out of it... I have the D6 currently and love it, but want more! I'm going to ride the T8 stock first for a bit, but I'm thinking those spacers could really help based on your experience. I'm about 205 lbs currently if that matters. Thank you and subbed ;)
Great review (and I also saw your long term review linked below). I got a T8 last month, and it's so helpful to read this article and your video. $2400US was a bit of a stretch and I'm feeling very reluctant to spend more, but a few tweaks are definitely needed for me:
- Mine came with Vee Tire Flow Snap 2.6 front & rear. Seems pretty good for front but I switched out the rear for Maxxis Aggressor for lower rolling resistance
- My XL has the handlebar stacked on top of all the spacers, and I still feel like I've got too much weight forward, so I'm looking to get a bar with more rise
- I had suspected spacers would help the suspension (front particularly), and you are confirming that one
Beyond that, I can probably live with all the other minor stuff for now
Out of interest, how much extra did all of your upgrades cost? (as proportion of the bike's cost)
Hey man, bought my t8 last year after seen ur review. Thanx heaps. Could you please what brake rotors and pads u upgraded to. Thanx. Keep up the good work mate. Cheers.
great vid brother
Glad you enjoyed it!
Love the colour
So sick!
Hi would you be able to do a review on the polygon n9
I wasnt happy that when my T8 arrived (around 5/01/21) the cool lil cardboard box inside that had all the paperwork and tools etc had been opened and pretty much dumped out inside the big box and the big box had a hole in the bottom from shipping so who knows what was missing.
More importantly- they had Vee tire co tires on the bike instead of the Schwalbes that they listed. - Those are worth about half as much by the way. -also a paint chip by the emblem on the headtube.
So I emailed them -only about the tires- asking them to take the vee's back and send me the Schwalbes...
The bikes online guys try to distance themselves from polygon like it was a different company and took zero responsibility for the manufacturer swap. (polygon is the only bike online bikes sells)
They said there was a shortage (obviously you can buy as many Schwalbes as you want on Amazon).
They said I should be glad i didnt have to wait longer for the right tires ( I did wait about 4-5 months).
Im ok with taking a chance to save money adjusting the bike myself etc, Im not ok with this company not sending me what they advertised and what I paid for.
I also received a damaged bike and terrible customer service. Avoided all responsibility against Australian consumer law. Left a review on the site to warn other potential customers but the review was never made visible to the public. Very high percentage of positive reviews are bogus as they just don't post the negative ones.
Same here.. They also downgraded my tektro.. To shimanos. Im pissed
Hey I plan on changing the rotors to the shimano slx what’s pads are compatible with the tektro brakes ?
That’s a sick colour man 💪
So sick!
@@trailtalkmtb6603 Doin solid work mate ,great variety of content.👌🙏🙏
HI Phil what chain guide with bash plate do you recommend for this bike? Mine is arriving in the next couple of weeks. and would like to get one
Im 185cm as well and trying to decide between L and XL. In this video you showed that you went with large and then had to open up the cockpit with bigger stem and taller bars. Do you think going XL you could have avoided having to replace bars and stem? Thanks.
Thanks for the update.
Any time!
@@trailtalkmtb6603 I ordered a T8 on Sept 30th and your first ride and live stream were what helped me make the final decision to purchase. Much appreciated.
So far I've only changed my flat pedals and dropper lever. Planning to change my saddle, stem and handlebar next.
How do you find the stock rims n hubs so far?
Finally, thanks for the cool update especially on the Tannus Armour. Will be checking it out as well. Haha
The wheels do the job well but are slightly heavy. If you want to accelerate a bit faster I would upgrade, should be able to save 500-600g.
Looks good
I wish I could get a polygon they look amazing but I live all the way in canda
Great site mate, your reviews are solid...Any Idea if there will be more of Siskiu T8's available this year?, ready to pull the trigger on my first FS. If they don't make anymore of the T8's, then I might just get the D7 which are in stock. I currently ride a hardtail 2010, F3 Cannondale(old school) with 26" wheels, so anything would be better in the descents. I would get a MED frame, I 'm 5'8" (173cm) tall and a reach of about a 23in(58cm), but can't decide on wheel size. Any advice on the wheel size (27.5 or 29) coming from old 26in ones.
Current word is they will be available at the end of the year but you really need to check often. They go quick!
very common design! looks like my cannondale habit
Did you have to cut the fork steerer tube to get the new stem to fit? I take it it's a 31.8 stem and bar??
So far running tubeless w. 2.5 DHF in the front and rekon 2.4 in the back., oneup 35mm handlebar and added a volume token in the rear shock and loving it.
Sounds good! What size token are you running in the rear?
moved from the .4 to .6?
Assuming you used stock rims on 27.5" tires, what tape did you use?
what do you think of the 2022 scott spark 970 ,or would you prefer a better bike whith more value
Planning to follow ur rear Tyre tannus armour set up after I get my bike... Should I go with the dissector or Nobby nic 2.35?
The new nobby nic tread pattern looks good! I do like the dissector tho. I have a feeling the nobby nic will be faster tho
my Siskiu t8 27.5 came with shock ID D5y9, and FOX website says it has 0.6 spacer. So for it feels good in such configuration
Woot 1st viewer!
Great mid review Phil .. can't wait to have this bike come back to pre-order. Admittedly I stuffed up and forgot to use your affiliate link when we ordered my wife's D7 last week - sorry about that :( ...
You are going to have to be on the ball with the pre order- sign up to be notified.
The pre order window was less than 1 1/2 hrs yesterday, before they sold out, luckily I got in before my ride & bought my T8 using my phone in the trail car park! T7 was a similar super quick sell out as well
All good mate! If you click on the link it should have a 30 day cookie retention. So if you forget theres always that :P hope your wife enjoys the new bike!
@@colind8090 are you kidding me??? I missed it again - that's 3 months now??? Australia or OS?
@@bluemy03 Australia, make sure U sign up for the notification & then watch your emails like a hawk! FYI watch out- hotmail marks it as spam sometimes - just to add to the degree of difficulty! Good luck
Great bike check! I’ve watched this video more than once in case I missed anything haha. Quick question: what token setup did you end up with in the front and rear? I’ve currently got 4 tokens in the front and 0.8 in the rear.
Thanks mate! Yep spot in im running the exact same :)
@@trailtalkmtb6603 thank you 😁 What about the pressures in the front and rear?
rear shocks have lockout also??
I have a problem with my T8. The shift cable keeps working it's way forward on the bike. This results in a kink where it places on the derailleur and also changes the derailleur position - which means I have to continually adjust the shift tensioner to keep the shift working quietl;y and smoothly. I tried adding another small cable tie just behind the rear cable tie but the cable slips through it too. Any ideas?
Does the bike come with tubeless valves?
mantap om 👍👍
Is this more enduro bike than XC bike? I mostly ride on flat trails in forest, not mountains and wondering is this bike suitable for my purposes?
you said you have 3 spacers in the front fork, what did you exactly install?
This bike very good
A bike paint job that suits your branding. When are the Trail Talk stickers coming haha
Need to work on that!
3:08 words 💯💯💯
How wide of tires can it fit?
Where did u get the pedals
Does the black tape from t7 a tubeless tape?i bought polygon because of you
Yes it's tubeless :)
I'm trying to decide which frame size to order and whether this is even the correct bike for my size. I'm 186 cm with a 64 cm reach, but only an 82 cm inseam. Stepover height on this frame is low so that wouldn't be a concern going to an XL, but I'm worried about getting my butt behind the seat when dropped if I go XL. Also, I'm 122 kg when kitted...will I be able to adjust the rear shock so I don't bottom out all of the time? It'd be my first full sus bike. Thanks in advance for your thoughts!!
Omg dude
Maybe choose XL and replace the rearshock with coil spring to reduce bottomed out
You state that you're using a 180mm rotor for the rear wheel, but it looks like you're using an adapter, and I thought the T8's frame was designed for 180mm rotors. Did you decide to go with 200mm on both ends? How are the brakes doing now? I find lots of mixed review regarding the Tektros online.
Could you talk about the T7 please
Very similar bikes, main real difference is the fork. If you plan to upgrade it and are starting out go the T7
What front mud guard is that?
Got the T7, looks rad, but i always catch myself looking at that purple frame...
how is the t7? , can't decide between t7 and d7
Owned a 2019 T8. The frame broke right near a weld in the top tube.
Bicycles Online / Polygon agreed to warranty the frame and said I'd get a replacement in 2-8 weeks. It has been 14 weeks and they haven't been keeping me updated and have generally treated me like crap.
I wouldn't recommend a Polygon bike when there are many other good options at around the same price range.
Sorry to hear mate, if there's anything I can do to help, let me know
Great update......How would you rate the Polygon T8 in comparison of the Marine Alpine Trail now? And how did you go with the .6 spacer and lower pressure? I am thinking about changing mine as well. But would like to see how you go after a bit more drops and jumps.
For my riding the T8 is my preferred bike. Only at places like Ourimbah DH and bigger drops I miss the Alpine Trail. It's been wet so haven't tested it enough quite yet! Will report back soon!
@@trailtalkmtb6603 Do you have any plans to compare the Siskiu T to a Marin Rift Zone (2 or 3) in the future? Provided you can find it in stock of course...
@@gpearce11 I've ridden both and its really pretty much almost identical. I do prefer the polygon slightly, it feels a bit more spritely but that's about it
@@trailtalkmtb6603 Thanks. I've been very interested in the Rift Zone 2, which compares very similarly to the Siskiu T7 (although I do appreciate that the T7 has a Deluxe Select+, which has a climbing switch, unlike the Deluxe Select on the RZ2).
The main pro for me with the RZ was its 515mm XL reach. Pre-2021 Siskiu T had only a 485mm XL reach, which ruled it out for me, but the new models are now 500mm. I'm 198cm (6ft 6in) tall, so I basically need all the reach I can get, but they're now close enough I'm tempted by the Siskiu.
In your opinion, do you think someone my height would appreciate that extra 15mm of reach (30mm if I add a 50mm stem), or is it not enough to make a noticable difference (seeing as its not really possible for me to test ride either of them before hand)?
What front fender is that. Looks great 👍🏾👍🏾
Rgb bike exist on earth
What else did you need when you changed the front rotor? For the caliper mount? Thanks!
Just need this bad boy (I messed up and got the wrong one the first time hahaha) www.pushys.com.au/shimano-sm-ma-f203-pp-203mm-front-disc-brake-adaptor.html?gclsrc=aw.ds&&gclid=Cj0KCQjw28T8BRDbARIsAEOMBcz0KSqWp04ItIpJm4euW5yC5HRIpQeuhANySob1run2HepsCt9B6JkaAsCLEALw_wcB
@@trailtalkmtb6603 awesome, might give it a go 👍🏼 Cheers
Good 😊
Can i have an opinion i want to get the polygon siskiu d7 2021 for my first full suspention bike and im not sure if its enough travel what do you think
what bike do you have now? its cheap but if you have an alright hardtail then id recommend getting something like in this video. but also geometary is more important than travel, travel can get you over stuff but geometry is what gives you confidence and the d7 is a cross country/down country bike so it doesn't have the most slack geometry so if want to get really rowdy then the d7 is not the bike. also take into account the type of trails you ride, if they are longer flatter and more hills then the d7 is fine but it you have more steep rough stuff then you're gonna want better geometry then the d7.
What kind of trails do you ride? It's a great dual sus to start on but if you are sending big jumps and drops something a bit more burly might be better
do you know anything about t8 suspension leverage curve?wondering will it be the same as d7(my bike)..
I have the graphs for the T8 but not the D7 but they do feel pretty similar
What do you think about getting the 2021 Marin San Quentin 1 and upgrading the fork to air and putting a dropper on it?
I dig it but prefer the 2 for value, check out more info here czcams.com/video/O8DDLXIskOw/video.html
@@trailtalkmtb6603 I was thinking of doing that because you not out $1200-$1400.
Right away.
get the 2, the 1 has a QR rear axle, my hub went loose in the first season. also you literally need to change the fork, it´s garbage. also the headset is for a straight steerer, keep that in mind. also climbing is hard on that 1x9. i wanted to do the same, i now ordered a Siskiu T7 and will be selling my SQ1. This Bike made me ride way less than on my 400€ Haibike in 2019.
@@erraldstyler Ok thanks!
I don’t know if you’ve seen GMBN’s Instagram lately - but in their short videos they often copy your TT 80’s logo at the start
Just check it out! Not close enough to get too worried about. I'll let them slide :P
Can you send me a link to the Shimano Break pads please?
Wondering if it really weights 16kg. Thanks
Definitely not 16kg. Stock without pedals it's more around 14.5-15kg
Hello, great video.. what would you recommend for spacer for myself a bigger guy 240 without gear. Feel like im maxing out at 350psi and still not reaching correct sag. and bottom in out alot on bigger jump.
I believe the 1.0 is the biggest you can fit, which would be what I'd recommend. You would probably need to run 27-28% sag too
350psi is the max too, so definitely don't go above that
Thank you!👍
Would a piggy back shock fit ok on the frame?
I have seen some people with one, so I would say yes!
Hmm 11 speed cranks (M5100?) paired with 12 speed drivetrain? How is that working?
Works fine!
20:00 bro we have the same bike and fork, I noticed it has 21 clicks. How many do you have?
What size tubeless tape is used for the 27.5" tire?
They come tubeless taped from factory but 35-37mm would be ideal
I like plush rear ends. Is this bike more poppy or plush?
It can definitely be setup as both. It's still a trail bike tho, so its spritely and poppy in that way and wont feel like a plush enduro bike
Hey Phil, what do you think about running a coil shock for the T8?
The linkage is progressive enough but I think it doesnt play to the bikes strengths. It's more on the trail side of an all mountain bike not a bruiser like the commencal meta TR and norco sight, which would suit a coil more
@@trailtalkmtb6603 Thanks for the info Phil. Loving my new T8 although need to get volume spacers coz keep bottoming out
want!
Can I ask what is the specific fork when getting the M 27.5? I saw other videos 27.5 only and some 29/27.5
As i know
27,5" : front and rear is 150mm and 140mm
29" : front and rear is 140mm and 135mm
Size doesn't matter on suspension its more on weight
CMIIW
In my country this bike not available in mixed wheel, but idk maybe 2022 or 2023 maybe exist
What's the reason you're trying to get away from the whole tubeless setup? Always gets alot of praise but always wondered if it was overhyped?
Just wanted a more durable rear tyre solution, that didn't require the mess of sealant on the trail side. Had a few walk home rides because a plug didn't seal the punctures
I'm gonna have to do some shopping now 🤷💰
T8 arrives in under a month. The volume spacers for the fox 34 I've heard a few times.

Just pre-ordered this bike and even though it will take 2 months to ship I’m pumped! On tires, anyone looking at swapping the front for something more aggressive? Like he mentioned, a DHR sounds good, but any other suggestions? Or maybe leave the tires stock? I’m in socal so my terrain is loose over hard pack
Awesome! Such a great bike. I'll have my full review up soon. Personally I would just get a soft hans dampf and run that up front. The tread pattern is dialled for loose over hard and hardpack
@@trailtalkmtb6603 thanks! Looks forward to that full review

I’m planning on ordering the T8 within a week. Do you think at 188cm and 97kg fully kitted, I should be getting a L or XL?
Definitely XL

Just add, tape and valves :)

Same question
I'm about the same height... same question
I am 168cm tall I just bought my Siskiu T7 Medium 27.5 with dropper post and I set my seat post to the lowest (max) which is just enough to make my legs straight down.
It has a short seat tube so you can go either way. If your trails are faster and plan to hit bigger features, I would size up. But if you are just trail riding, go the medium
Hey Phil ... Question - why did you add longer stem and riser bar rather than get a XL bike??
I received my T8 Large after waiting for 3 months last week. I feel a little cramped and can't decide if I return it and size up to XL or stick with the large.
I visually compared our set up and noticed my seat post looks higher and seat rails is set as far back as possible compared to yours which is in the middle.
Im coming from a 2015 Whyte G-150 in Large - which was too small for me and I needed a 70ml stem to make it feel somewhat more comfortable ... So confused as to what to do here as I'm not sure if it's just a change in riding position and I need to get used to it or ... I need to get the XL. I don't really want to wait 3 more months before a XL comes back into stock ...
I'm 183cm with arm span of 193. Buyers size guide shows me towards the top end of size L.
Appreciate any feedback or suggestions.
FYI - I opened my shock and found it already had the yellow 6mm token standard.
Interesting, was it on the 27.5 or 29? What is the fox id on the shock?
@@trailtalkmtb6603 hey Phil - tell me about it .. this was after I bought the kit too lol... 29er and D5Y9

Hey Phil, you upgraded the rotors to 203 up front, what adaptor is required to do this for the front caliper?

I have the 2021 T7. What would be the first thing you would upgrade on the T7? I’m considering wheelset.
I have the T7, first upgrade was a saddle. The stock one is crap.
Seat for sure, then brake rotors and pads. After that I would do the fork. The wheelset works well and you wont notice the performance gains compared to these
Ha, I actually like the seat :) so what fork would you recommend ?
Pike ultimate would be great
@@clint2627 it might be comfy but the pointy end and rubber really grips onto your shorts and gets caught. It's more a safety vs comfort scenario
