Good video. Not a big weight weeinie guy but it is pretty obviously the new 48/58 wheelset is where the system weight savings are. It’s a big gap to the Sworks frame weight.
Does anyone know if Factor fixed the rear Thru-Axel problem that exists on version 1 of this bike? Also, there are lots of posts online about the bottom bracket creaking and the headset compression plug/steer tube problem. Hopefully all of these problems have been fixed on this 2024 model.
The headset / steerer problems were fixed quite early on. I got a new fork in 2021. My BB area does creak on and off which is annoying. We Loctite d the blue cups in and I regrets the crank axle often. Right now, it's pretty quiet, let's see how long that lasts!
@CyclespeedTours - What does your Ostro VAM V1 Total Bike weigh with pedals? In Pedal Lane PH CZcams channel, they show the complete bike built up with pedals in size 54cm is a Total of 6.88kg. | 15.16lbs. Are you saying your Ostro VAM V1 Total Bike weight with the same pedals weighs less than the V2? The V2 Frame & Fork might be heavier than the V1 but it seems the V2 Total bike weight is less than the V1 and that is probably mostly due to the new Black Inc. 48/58 wheels that only weight 1250gr. Also, the slight increase in weight of the V2 Frame & Fork supposedly makes the bike more snappy and gives it faster acceleration and better climbing than the V1 because of the increase in frame/fork stiffness. So, lighter weight is not everything. In the end, it comes down to performance and you really need to ride the V2 to make a fair comparison to the V1. One other thing to know is the V2 in the Natural Carbon Black color frame reportedly weighs 100+ grams lighter than the white frame.
6kg. It doesn't mean much to give a full bike weight, because you could have lots of light or heavy parts on there. For example, my bike is so light mainly due to the 960g tubular wheelset. Indeed, Factor cleverly conceal the increased frame and fork weight by saying how easy it is to build the bike to 6.8kg. But just about any decent modern road bike can be built to 6.8kg, so this doesn't really say much. I could build a V2 to 6.3kg, no problem, but I can build an SL8 to 5.7kg, which is what I prefer to do. As for stiffness, I only put out 280W FTP (65kg) so if an SL8 is good enough for pros (450W, peak 1500++) then it's OK for me. F=ma, so an increase in weight simply cannot = faster acceleration, unfortunately. This is why hill climb bikes are stripped to the bare minimum, because the riders understand Newton and gravity.
Thanks for sharing. I am not looking to upgrade my ostro quite yet, but doubt I'll do it if the weights you are showing are consistent with others reports. Drives me crazy when companies lie about weights. Huge turnoff even if the bike is amazing in every other way.
Thnx for the informative content. I was highly thinking about this for this yr and now I’m thinking of just upgrading my groupset instead. Nothing out there is seriously calling. I wish Cervelo would make a lighter version of the S5. Disappointed about the Vam 2. It’s a very good looking ride.
@@andreassakkas7234 Factor claimed size 54 "painted frame and fork chrome/black", i always take these weight claims with a pinch of salt...whether is Factor or Pinarello...(which nonetheless I have both)
Maybe it all comes down to a misunderstanding. As far as I know, the official weight mentioned is for a Chrome-frame(being Factors lightest paintjob) that adds an extra 35g from the paint. There might have been a mix-up, thinking the weight included the paint for frames ranging between 150-200g... And the white paintjob is the heaviest one as well.
@@JesperGejlHansen I don't think it's a 'misunderstanding' I think it's deliberately misleading. If there is such a big difference in weights then tell us , and also show us the customer that has ANY TYPE of Ostro V2 weighing 820g in a 54.
Looking briefly, the price difference between the SL8 and Ostro (SRAM Red) is $3000 US. I guess people will have choose between the weight savings vs cost when looking at these two bikes. Its a shame the Factor isnt lighter...
That doesn't really tell you very much. The wheels can make a huge difference. Mine only weigh 960g the pair for example, so I could build a new Ostro to 6.3kg, but I can build an SL8 to 5.7.......
That’s surprises me with Factor! My SL8 Maganta 54cm was 700g frame. Whole bike With weight Weenie parts is 5.9kgs. Will get a little heavier now I have swapped some of them out probably 6.1kgs
@@CyclespeedToursThat’s huge. I know the head tube on the SL8 divides opinion but I like it myself not a huge leap really from my SL7 but it’s a noticeably more comfortable ride from the rear. Would have considered the Factor myself but after seeing this video glad I have the SL8. I will be Very interested to see what you go with!
@@SAnderson77 I always liked the SL7, and the SL8 isn't so different. I'm OK with the nose! It looks light and fast whereas the Ostro now looks a bit porky. Shame.
@@CyclespeedTours Well if your swinging back to the S-Works stable, now for which colour!? The white one is the heaviest paint of all FYI but you might already known this and there are some LTD ED team frames knocking about in Europe Bora/Soudal/SD Works. Darimo Aero bars Darimo post. I think you would be knocking around 5.6/5.7kg territory. Crazy Light!
@@SAnderson77 I think I've found a 'Ready to Paint' so hopefully around 675g. Only the Bora and SD Works available otherwise and not so keen on those. Yes, I think 5.6kgs.
I'm a bit surprised you were considering it anyway given all the BB issues you had. Also it's as overweight as you'd expect if you look at the weights of later V1 Ostros and the new O2.
Yeah, I was prepared to give them a 2nd chance with the BB area on the V2 OStro (even though it's the same system). But I was already very doubtful that their weight claims were correct which is why I made it a condition of my purchase. Specialized can get below 1050g for frame AND fork, FULLY painted, so it is achievable in the right hands.
THanks for the video; I too am weighing the SL8 vs the new ostro. I'm still leaning towards the Ostro because I still don't love the looks of the SL8, the wheelset is not as nice IMO and it costs $2,500 more for the RED Power configurations. I also want the ability to use a clip-on bar and Black Inc has the best cockpit for this, better than the ENVE I have now. Given that I could easily loose 10lbs of body weight, I think I'd rather live with the extra 400g (1lb) of bike weight be on a bike I love to look at.
Get a Tarmac SL8. I use to have an Ostro, I was inspired by you to get it. Because of what I do I don’t keep bikes for too long but SL8 so far has been my favorite bike I have ever owned. I have got my sl8 with Ultegra down to 6.88 with everything. With Duraace I have got it down to 6.59 in size 54. . My best and favorite set up so far has been with clx alpinist for climbing, and Enve ses 4.5 hookless for all road. Clx rapids 2 are complete dog shit. If you get clx rapids get gen one, they are 200 grams lighter than 2 and you can set them up tubeless without ever having any issues. Don’t worry what they say they are tubeless compatible, I have tried them with every set of wheels with every type of rider you can imagine. I assure you there isn’t a human in the plant that can set up tubeless tires, or has set up more tubeless tires than me. At least 5000 times minimum.
All known frame brands give frame weight only, but the complete frameset is frame plus fork, and sometimes plus seat post. And this turnes everything into a lie.
I’d much rather have a stiffer bike than a lighter bike. These days bikes are getting so light they’re Comprimise no in structural integrity! Coming from a 200Lb 6ft rider so take it from that perspective.
With the pros riding the SL8 and pushing over 1500 watts in sprints, I don't think there are any major stiffness issues, but I get what you're saying about a heavier rider wanting some strength in the frame. I have a friend that is much bigger than you and he is fine.
@@CyclespeedTours pros are very light yes some put out 2000 watts but the bottom bracket area is never the issue plus we’re seen handle bars break and pros have 10 bikes all the same we ride our bikes alot longer then pros do I wouldn’t use that logic with comfort. We should get more durable bikes were not pros racing tour de’france. At least I’m not.
I mean, if it is out of passion, building a light bike just because it is fun, as a challenge so to speak, fair enough, go for it! But out of performance reasons or because it “feels” lighter… sorry but that’s just stupid. And it is the ongoing and never-ending disease in road cycling. Engineering and development would be such much further, if 100 grams here and there wouldn’t matter so much because so many customers are stuck forever with the most primitive metric there is. At the end of the day we are not talking kilos, it’s 200 grams or so. With a 6,8kg bike that’s less than 3 percent and with a 70 kg rider less than 0,3 percent for the system weight. No weight weenie will ever feel that in a blind test…
@@nuttynut722 if somebody would offer a bike with flawlessly manufacturing quality, best in class aero and stiffness and on top a nice geometry and cable routing solution for an average rider and home mechanic, I would be happily pay top end prices even if the frameset was over 2kg. Because weight doesn't matter one fucking bit if you do the math. But I mean, it is the cycling industry. Good engineering and manufacturing quality...good luck finding that...
@@MS-bw7yt for the amount of money they asking for a bicycle, I would demand they "at least" meet spec "they propose", weight might not impact the performance at all and I know that, it's about credibility, only bicycle and tech industrial get away with that kind of claim
I have been following you from pretty much day one. I always enjoy your videos but this one I just don't get. Your bike shop must love you :-) It pays to research before committing and messing people around. You are obsessed with this weight-weenie stuff. We have seen you having issues with wheels and now a frame. All manufacturers are misleading with the weight information. It's down to the customer to get it checked out and weigh the frame etc. I have raced all over Europe and had all kinds of frames and wheels. I have had ultra lightweight skittish bikes and slightly heavier bikes. Nothing really held me back. I've had lightweight gipfelsturm wheels and bora ultras etc. Your obsession is actually ruining your enjoyment my friend. It's so tiring just even watching this stuff. I really don't mean to cause offence , but please just get on and enjoy your cycling !
As an old regular, I appreciate your comments. What I would say is that noone was messed around. My LBS knows me well, and it was made clear that I would buy the frame subject to the weight checking out. It didn't, but there are no hard feelings anywhere. My 'research' told me that a 54 should weigh 820g, but the 52 weighed 915 and the fork has put on 100g too. For some, I totally understand that this is meaningless, but as you know, I like to build a light bike, and if the frame is heavy, then you are crippled from the start. When spending 5k on a frame, it would be nice to have some truth in it's specs. If I buy a Porsche with 400hp, I don't want 350, and a dishwasher at 38dB, should not be a noisy 45dB.......etc. etc. The wheels you mention were also out of spec, but it was impossible for me to know this in advance, or indeed, why would I think to check their diameter? I now have 2 pairs of their tub wheels (339T) which I think are great, at 960g. I cycle 16k kms per year, and I love every minute. Would I enjoy it as much on a heavier bike? Maybe, but I have ridden friend's bikes and they just aren't as 'flickable' as mine, so I think the light weight is a part of what I like in how a bike rides. I'm not TOTALLY obssessed! If that V2 had been say 850g, I still would have bought it, but it was just too far off, and I feel that is now an 'aero bike' not an 'all purpose, light aero bike', although no doubt it is still a great bike that rides well. They will sell many, and have lots of happy customers. I get the SL8 tomorrow, and I will build it light, as I always do, and then let's see how it rides! It will be interesting to compare it to my Ostro V1.
I think you know this rule. The bike could be light and stiff and not aero, or aero and stiff and not light, or aero and light and not stiff. And we are always somewhere inside this triangle.
My 56 black/black is 890g frame and 480g fork. If you want to compare framesets then maybe you should have spent time reviewing like for like. Your V1 doesn’t have the paint the white V2 has so this review is totally unfair.
it 's surprisngly that everyone is talking about weight and aero but not safety. Didn't heard YET about any frame break downsI won't how sl8 is taking fatigue over time. Time will tell.
Yep,disc brake bikes are pretty porky. When i compare new scott addict rc with my addict rc ex pro bike(rim brake 2018)it adds with all that proprietary components and disc brake system around 500-600 gr.easily. And you really get nothing! Aethos is best disc brake frame IMO.
@@CyclespeedTours it is also by far the ugliest! Life is too short to ride ugly bikes. Also everyone has or will have a Tarmac. Your Factor is by far a better looking bike and more unique than having yet another Specialized (yawn) and how will your channel be any different than the hundreds others ones with a Tarmac (yawn).
@@omarcastz There is some truth in this - the Ostro is a good looking bike, and the new one I like, especially with the new paint job. And probably, yes would draw more viewers. But I have very few subscribers or viewers anyway, which doesn't bother me so much as I just make videos for my own fun really. For me it's hard to accept a heavier bike and hard to accept being lied to.
Sorry to hear, was interested in finding out more about the new ostro, onwards and upwards.

When i compare new scott addict rc with my addict rc ex pro bike(rim brake 2018)it adds with all that proprietary components and disc brake system around 500-600 gr.easily.
And you really get nothing!
Aethos is best disc brake frame IMO.
aethos is like the old O2 ... a wet noodle.
@@pmcmpc lucky you got to ride both of those bikes, impressive
Maybe if you are 85 kg.
But for him with 60 kg would be more then stiff enough
don't do it! No specialized SL8. Your Factor is better.
But the SL8 is by far the lightest!
@@CyclespeedTours it is also by far the ugliest! Life is too short to ride ugly bikes. Also everyone has or will have a Tarmac. Your Factor is by far a better looking bike and more unique than having yet another Specialized (yawn) and how will your channel be any different than the hundreds others ones with a Tarmac (yawn).
@@omarcastz There is some truth in this - the Ostro is a good looking bike, and the new one I like, especially with the new paint job. And probably, yes would draw more viewers. But I have very few subscribers or viewers anyway, which doesn't bother me so much as I just make videos for my own fun really. For me it's hard to accept a heavier bike and hard to accept being lied to.
