🤣🤣🤣🤣🤣

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

I was wondering why belt drive seems to be no option in TT? Like, Pinion gears combined with belt drive seems to be the lightest option, that also brings the fine stepped 18 gear transmission into play.

I am glad you enjoyed it!

Im glad it could help!

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.

It will feel so good! Still one of the fastest TT bikes out there I believe

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.

Losing weight and gaining power are uncertain; throwing money at the bike makes the gains a certainty. I don’t know about you, but going for things that give certain results seem like the smarter choice.

It’s quite hard to describe so will do my best. You don’t really feel the reduced drag, you just notice your speed is a lot higher when you look down at your gps. You also notice your average speed is a lot higher after the ride. Effort levels feel the same. It’s a case of as you go faster you need exponentially more watts to hold a higher speed rather than a linear graph. So at 40-50kmh it’s quite easy to save 100w But at 25kmh it’s hard to save that kind of aero drag.

I appreciate the kind words!

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?

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

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.

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.

It’s from a brand called Erstwhile. It’s actually really good quality and very soft.

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....

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 kzfaq.info/get/bejne/o8yJa9hem7bdfHk.html

Legend ​@@cyclingunboxed

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

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.

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.

😂 never even thought about it but now I like it even more

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.

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.

Ok 😂

I guess when you get upgrading the do start to add up

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.

I’m 192cm so 6’4. This bike is a M/L which is like a 56. It’s the same as the S/M on this bike but has a longer seat post and mono riser. I am just on the edge of the max seat post height but this size rather than the L fits my reach better as I have very long legs and a regular torso length.
