I did all of these and I saved so many watts i don’t have to pedal anymore.

🤣🤣🤣🤣🤣
It also looks very save looking down in the aerobars.
compleatly agree with your opinion. Great Video with all details and explanations. Every new cyclist need to see this :)
awesome vid great info and actually really entertaining!
I am glad you enjoyed it!
Thanks bro helpful video! Nice work!
Im glad it could help!
Its very rare Im not calling out errors and misconceptions in a cycling related video but all of your information seems spot on. Maybe another upgrade could be high quality (cpmpressionless) shifting and brake cable and housing. Im still new to the channel but this is probably the best homegrown cycling channel at the moment. I dont watch the ad riddled shill channels.
I’m glad you liked it!
Compression less housing is definitely not one I have thought about or actually done myself. I would like to give it a go now.
@@cyclingunboxedthat's because you're above your head giving "reviews" and advice with such little experience. Would be better to gear your channel as a learning novice. Nothing wrong with that and it's honest
Good info
Nice video! I ride the TT bike just for fun, so I have been riding durable training tires, but I think this year I am going to do some fast tires and upgrade from butyl tubes to latex. I am on a Giant Trinity, so still rim brakes here.
It will feel so good! Still one of the fastest TT bikes out there I believe
Internal spoke nipples could be a saving? Custom fitted Skin-suite? You could also go for a Bike-fit, which could dramatically change your position and aero savings.
Done most of the upgrades you mention, except for aero aero bars (I am looking into a Speeco TTX), Wind tunnel, Ceramic bearings and OSPW. The "reaching for it" is so damn expensive though :(
I have struggled to find any information on how much savings the hidden spoke nipple have. If you have seen anything, please send it my way.
Yes custom skin suit is a fantastic one! also bike fit I fully agree with for some people. I think I would find it hard to find a bike fitter with the aerodynamic knowledge to really optimise you though.
Maybe one day they will come down in price. I think they might be too big of a niche though.
Excellent look.
Two things that intrigued me that are. . . sort of related.
Power Meter? Both on-bike and off-bike.
Pedal-based power meter is what I have and love it since I know I can put it on any future bike I have. So I'm shocked that it on the high end, yes they are pricey-ish but the amount of cross-compatibility you can have with it is a neat feature for how simple it is to do.
The other one that is more related is a direct drive indoor trainer. I shouldn't have to tell anybody who is remotely familiar with the world of bikes what this is to explain the massive benefits this provides from being used from a self-guided aerodynamic positioning tool to (winter) workouts and everything in between. So it being left off is strange.
Power meter is a great upgrade. For the order it’s more of an essential/ purchasable / reaching for it. It’s number 13 on this list but I guess it doesn’t have to be 13 on someone else’s list.
For the turbo I thought the same as you. I assume the most people would know and have one if they were this far into time trialling. It’s also of course not directly making the bike faster during a TT or triathlon. It’s an indirect way of making the bike faster if that makes sense?
Best video on CZcams
I appreciate the kind words!
Nothing beats losing weight and increasing power. Free if charge and you will also save money for these upgrades. Nice position when your racing very aero 😊
which eventually becomes impossible if your well trained; power will always reach a cut off point and will start to drop as you get older; been clever aero wise will gain way more speed than extra watts ever will especially as you go over 25 mph. essential if your aiming for 30 mph
if you need to climb, maybe. But if you look at the actual data, it's pretty minimal unless you have a lot of weight to give. A couple pounds is pretty minimal.
Jason I recently purchased the bike and it came with Hookless rims . Zipp 858. I did a search on your channel to see if you specifically addressed this issue and I can't seem to find it although I do see a lot of information on tubeless tires. If you do have a video on the subject please direct me to it. If you don't can you give me your opinion on it or maybe make a video on it. I am concerned about the safety of those rims. I think it is notable that some wheel manufacturers are convinced that road hookless wheels are not the way to go. Eg DTSwiss.
Hey! I don’t have a video on it but I do have an opinion.
Which bike did you buy? (I am curious)
The 858 is an awesome looking wheel!
When it comes to hookless I like:
Tubless (less rolling resistance)
Cleaner transition from the tyre - rim
Lighter
A bit cheaper to make.
What I don’t like
The max psi is too low for someone of my weight. Especially for a deeper wheel where you will be running a narrower front TT tyre. I would go 28mm wide minimum but wouldn’t go wider for a TT tyre.
If you are light enough though it’s ok.
In terms of safety I think they are probably ok. There are a few stories out there but I reckon they are fewer than they seem.
Personally not a fan of hookless (mainly because of the max psi issue). I need to run around 80psi for most tyres.
I hope that helps a bit. They are just my thoughts. Of course if you have any other questions, please hit me up.
Great information bro 👍 , but i want to know custom skinsuit are fast because of linnings or cloth material , or any type of clothes with linning will work same ????
Earlier i made a disk wheel cover by a aluminium thin plate and with tape sticking on spoke cover the whole spoke area, don't know how much it works but definitely save some watts. Now i am thinking to cover my aero bars with aluminium plate to gain custom aerobars benifits.
I believe the custom skinsuits are fast because of a combination of those things but the main reason being that when you go custom, the skinsuit will fit you perfectly. Tighter and less wrinkles which decrease your drag. Quite significantly over 45kmh.
The home disk wheel has been shown to work well. Would be interested to see what your creation looks like.
@@cyclingunboxed here in my country cycling is not on heigher lavel, custom skinsuit facilities not available, and you can only buy on High cost. And everyone has their financial boundaries.
Well Its my pleasure if you want to see , thanks 🙏
But how to send pics?
Feel free to send them to my Instagram:
@jasons_cyclingunboxed.
@@cyclingunboxed ok thanks
shaving saving
The t-shirt... I love it
Where can i have it? Please...
It’s from a brand called Erstwhile.
It’s actually really good quality and very soft.
Wheels after body position and they can be cheap if you don't buy a big brand.and still just as aero and some are better too.
I do like a lot the innovation from a lot of the smaller brands like from Parcours wheel I have on the bike. However I still think you are looking at £1000 for something you would be willing to buy new. So cost per watt is quite low.
What is the brand of that water bottle?
This one is Orbeas own bottle designed to go with this bike.
You may be able to find it on their website but I have only ever been able to order parts using my bikes frame number
Just out of curiosity- your pedals pointing up. How do you stop that from happening?
That’s the way that they sit as they are designed to be heavier at the back. It makes clipping in easier as you are pushing forward into the front of the pedal to seat it properly when clipping in. I hope that makes a bit of sense. If it sat flat it would take more time to find the spot to seat the cleat on the shoe
@@cyclingunboxed tell that to my scraped crankarm....
Which magnet and light did you use on the front???
It’s a bit of a boring video (I was rubbish back then 😂)
But here is the guide on how I did it:
Intergrated TT AERO front light

Legend @@cyclingunboxed
bike rolling resistance conduct their studies at low speeds (not TT speeds) and on a smooth metal drum so the data will be irrelevant for a good TT er; better looking at aerocoachs data done at 45 kmh which will tell you the tyres to buy
I have had a look and compared them and they seem to correlate very closely in which order they place their results.
I’m glad you said though as I’m also going to put it in the description so people have more data to look at.
Interestingly Josh from Silca has suggested before that the drum tests correlate very strongly with what they see in real world conditions.
Missing first best upgrade. long arm cups. Staying comfy for longer equals a faster time if you are able to maintain the position for longer without sitting up, cups like culprit, tri rig, etc
I can certainly see how for some ultra endurance events this could be good.
For me know even up to 70.3/ middle distance triathlons, I have never really thought about this as I have been more than comfortable in the pads I already have.
May think about it on my first full IM this year though.
No matter how light, or how aero the bike is, it's still dependent on one little thing.
Indeed it is!
I would argue that a lot people into time trialing and triathlon are already quite close to their genetic performance ceiling. Then these gains start to make the difference.
Legs shaved arms shaved head Giant mane! this is how the cyclist do
First off, the tyre logo alignment and biggy smalls 🔔 super nice
Shaven legs are part and parcel of cycling.
I dont understand why people need convincing, they need to get that chip off their shoulders about the topic OR just where baggy pants and shirts and enjoy their commute.
Find me a professional male swimmer who has a hairy chest, arms and legs....
Thumb nail says you save 69 watts nice
😂 never even thought about it but now I like it even more
See how many watts you save in a side wind absolute bollocks
Thankfully for me I am 80kg so the wind doesn’t hit me too hard. Also wheel profiles are a lot better designed for side winds now days. I have never had a problem with these wheels and that’s with some TTs round the goodwood race circuit which gets very windy.
Fignon Ponytail is making you look like a Neub.
Ok 😂
You would gain 50 Watts for shaving your legs😂
😂
You forgot the ospw give you more drag.. poor upgrade.
Also the socks you talk about.. our legs doesn't spin like a golf ball, so all those comments shows you don't know how a golf ball works. It's just marketing.
I will agree somewhat with the OSPW here with the drag numbers increasing but there are 2 things
1, the drag is so minimal from the wake back there in the bike I can’t see it being greater than the watts saving from the reduced articulation of the chain.
2, the frontal area which has the biggest impact is barley larger than the original pulley system.
This is an upgrade that is far too much for me to justify the cost but ceramic speed now do an aero fared OSPW you counteract this.
I also think the 2 watt saving comes down as well when you wax your chain as that is already so efficient. (It does look cool though!)
On the aerosocks however I would like to dispel some myths for you here.
You are right, the leg doesn’t spin like a golf ball but the spin only produces a Magnus force to curl the path of the ball. The air just needs to travel over a surface and then trip the air.
The trips are there to turbulate the air to maintain more attachment around the leg and reduce the wake behind the leg (or cylinder). This of course goes for the arm as well. That is why there is also trip flows on most skin suits.
Most aero socks are flat on the front and the trips only start at the side of the leg.
The next advantage is smoothing the shape of the shoe with the covers but the socks alone work almost as well.
There is tonnes of test data out there from Nopinz, Silcas Josh portner, and aero coach to back this research up with hours upon hours of wind tunnel test data. If you really want to know more, Silcas marginal gains podcast goes quite deep into this topic.
My final point is that there is a reason almost every pro cyclist and triathlete wears an aero sock / calf sleeve no matter the race.
I have linked some cylinder trip and flow aerodynamics papers below if you have access to a research portal that you can dive into. You are also welcome to provide me with research countering my points made above and the papers I have linked below. I would like to see them to further my knowledge if so.
I hope that clarifies why I still maintain this as one of the best bang for buck upgrade.

Cheap TT bikes? Theres no such thing
I guess when you get upgrading the do start to add up
