Road Bike Frames, Wheels & Components / Re: the new Van Rysel RCR-F

Bigger tyres inherently create more rolling resistance. The reason they can perform better in the real world is because they are the only real source of damping on the bike and because they enable safe use of lower pressures. But as long as you can stay in the operaring window of the narrower tyre, it will perform better than a wider tyre for the same percieved comfort/casing tension. And also it'll be aerodynamically faster and less affected by crosswinds.

Frame flex doesn't measurably affect power transfer, only effect it has is mental and on handling. Too much stiffness, does however worsen the damping ability of the system, slowing you down on rough surfaces, and creates more physical and mental fatigue.

I think you misremembered whether wider or narrower tires led to lower rolling resistance and now you are doubling down

If I could go back I probably wouldnt get a slc3. Bikes been flawless and has perfect QC, but the speeder 55 looks like a much better value. The winspace brand promises better quality and aftersale support, and if that turns out to not true then they are not worth it. TBH I was looking at buying the slc2 when it was on deep discount, then I seen the SLC 3 get announced and it was more of a impulse purchase.

I have a "winspace authorized dealer" bikeshop in my town and they said they warranty winspace frames/hyper wheels and they said winspace is great about covering repairs under warrenty on their wheels (theyve never seen a frame come in for repair) so that is reassuring

I think the biggest difference between buying a decent value bikeshop bike or building a premium chiner is wheelset. For the same ~3000$ pricetag the chiner would have a great wheelset, while the bike shop bike will have terrible wheelset. Also factor in the crank, handlebar width, tire choice... I built my own because of all the bad components that I would have to replace.

I do have the SLC3 and can say as for ride dynamics, it rides like a bike, it has pedals and when you spin them it goes.

35mm would just be slightly lighter. Usually 40-55mm deep wheels have such a small weight penalty over ~30mm that its a no brainer to get the deeper wheels. Crosswind stability for wheels below 55mm deep is not much of a concern. Id don't think 9velo is a good value. I avoid many of these premium Chinese brands that are trying to compete with western brands. Price is double that of an OEM, and the product and support/warranty is the same, sometimes worse.

The standard elita one seatpost clamp is the worst. Feels like your breaking it when torquing it to spec. If you tighten one bolt too much before the other the seat angle will change. Then youll get slipping after 200 miles. Almost a deal breaker for me.

I did buy a V shaped flexing seatpost, the Elita One Master. It has the best seatpost bolt ive ever used so far. The dampening really isn't a game changer tbh but is noticeable. I am sort of worried about the durability, probably wouldnt recommend to heavy

INCOMING...

65mm 34 external/26 internal - 5.0mm carbon spokes and ceramic bearings.

I opted for the T800 instead of the lighter T1100. Still lighter though than my Magene Ultra DB607, Winspace Hypers, and Elite Drive/Helix as similar depths. Thanks Peter!

My second wheelset from peter just shipped, D50CU36 rims, t800, 24/24, pillar 1420 and they are 1350grams My first wheelset is similar to my new except D65CU33 and weight is 1500grams.


Based off my wheels and Pattys wheels here, it seems the T800 rim weights have decreased from peters wheelset from last year. T800 wheelsets are ~70grams less than what I estimated from previous wheels on this thread. I am definitely not complaining  8)

I'd hardly consider shimano the gold standard of cranks

How bout you crank me off

How do people feel about the new Winspace C5 Aero? It looks vaguely interesting but I'm suspicious it might be more of that faux aero thing several brands are doing now.

C5 aero looks good if you want an endurance aero frame, except without the endurance geo and with no money spent on r&d or testing for aero

I don't know exactly if the question has been asked here before, I'm interested in the T1100 wheels, but not with carbon spokes but rather with the Pillar Wing 20 for maintenance purposes.

What is the exact difference between 21 and 24 spokes per wheel, are the hubs different or is the difference 36/54 ratchets?

21 and 24 spokes will have different rider weight limits, and more spokes will be more redundant in a event of a spoke break. 24F/R is most common for steel spokes. Could use 24F 28R if your a big boy, or 21F 24R if your smaller since more weight is on the rear tire.

I think the only issue with recent aero frames is the stack is too low. 32c Tire clearance frames can typically fit 35c


If we just had a specific bar&stem that added a good amount of stack without looking stupid or require 100 spacers that would solve basically all issues

This area of the bottom bracket was open on previous winspace frames and many frames with semi internal cable routing since that was where a cable guide piece went. I am sort of thinking this frame could be an evolution of one of those older frames and that area just sorta got closed up with this minimal amount of material. All I am saying is its possible this is not structurally compromising the frame.


I dont think a credit card company will consider this grounds for a chargeback. But hopefully itll pressure winspace to provide some sort of backup

D50CU33 w/ T800 and 24/24 steel spokes is 1400g at $600 shipped to us


D50CU33 w/ T1100 and 20/20 carbon spokes is sub 1200g at $950 shipped


Spending 50% more on less durable wheels to save ~200grams is probably not worth it for any of us who dont race

I would not put Ultegra Di2 on the hyyge


hygge requires duraace minimum.

I'd also include frames being replaced via warranty claims as part of the price point too.

In my recent video featuring a set of $3000 ENVE SES 4.5 wheels, several ENVE customers mentioned how good ENVE's warranty service is. And several viewers also said this is because the company essentially builds into their pricing two "free" replacement set of wheels under warranty, no questions asked, within the first three years of ownership. Basically the customer is paying for 3 sets of ENVE wheels upfront.

By this logic if Chinese brands selling $600 frames were to offer a similar warranty/service, frames would probably cost closer $1500-$2000. Makes sense why it's in their best interest to just produce frames as robust as possible even if with a slight weight and ride comfort penalty.

I wonder if Winspace, Tavelo, and SEKA would do the same. Considering their frames cost about the same.

I spoke with a winspace authorized dealer in my area before buying my SLC3 to ask about their warranty. He said hes only ever seen a winspace frame once in his life, a t1550 and it didnt need repaired. But he did say he sells a lot of the hyper wheels in store and they are better than most brands with warrantying things when needed, but he hasn't had to warranty many of wheels at all.

Im saying this because I've run cfd simulations on various rim shapes with various tyre sizes. 105 just has no meaning

That great that you disproved a BS 25yo wind tunnel test with an even more BS CFD analysis.


I actually skip wind tunnel testing and CFD analysis, I acquire a rim profile in a .jpg file format and scanning with my eyes I am able to calculate the aero performance of a particular tire-rim transition with a 100% margin of error
