@Peak Torque How much do your rotors weigh, and do you have any intention of selling them on your website?
@PeakTorque
@PeakTorque Ай бұрын
They are heavy. Probably the heaviest 140 rotors out there. Thats the point, more thermal mass than anything else on the market under 180. Theyre harder and more conductive…which should tell you something about the material choice 😊 They likely wont be for sale as they are incredibly expensive to make being one piece with a spline. Its a passion project for me to surpass the bike industry in terms of performance. I think I’ve done that - its easier when you dont need to think of the commercial side of mass production and profit margin.

A friend of mine bought these wheels, and the rear wheel main bearings became contaminated & rumbly in a very short time. I knocked them out and pressed in some decent steel ones for him: no further problems. Hybrid (or even full) ceramic bearings are more trouble than they are worth on a bike (not including the misplaced smug factor that they lead to amongst users of them), and as a very knowledgeable engineer once told me, ceramic bearings are designed and (used to be only) specified for very high speed/temperature/pressure applications (turbines, high speed industrial gearboxes, etc.) and have no place on a bike where rotational speeds are rarely beyond 400 rpm. They have next to no deformational tolerance, so when they are stressed beyond their design parameters (usually not those of the bike component they have been dragooned into) they do things like this: getting very grumpy very quickly. But try to disrupt the snake-oil-influenced mindsets of the average cycling engineering fashion victim (out of pocket of ££££ thereby) and you'll get scoffed at. Because (insert name of bling cycling component seller here) can't be wrong, because all the other 'engineers' at all the other companies are doing it too. Even Chris King, nowadays. I could go on.

another advantage of ceramic bearings that doesn't apply to bikes is that they don't provide a path to earth for shaft currents that are found on motors running on VFDs. this means no discharge across the bearings (back to the motor housing) and the pitting in the races that can cause. You still might need some other for of shaft current dissipation, like a brush ring, or similar, but at least it won't go through the bearings.

I agree with your findings on the stiffness. I have the same wheels, sort of.I have the CS5055's with the 21mm internal for front/rear. I can pull the end caps off easily. I find my Campagnolo Bora One's to be stiffer especially when taking sweeping corners. The CRW's tend to understeer compared with the Bora's. I was really not expecting that with the CRW's. I think the wheels are OK but just don't live up to the hype. Maybe I should have gone for the Magene 508's.

It has been a long time since you showed/reviewed wheels from Light Bicycle. I'd like to see it again with their WR series of wheels - they are nice and wide like people want. (or - if you want to review climbing wheels - the AR25 rims) One thing I like a lot about them - you can fully customize the wheels - choosing hubs.. ratchet teeth (for DT - 36 or 54 tooth).. spokes.. nipple type.. whether you want spoke access holes in the rim.. I think they still sell quite a lot of wheels but don't do a lot of marketing like some of the other brands that we hear about more. But their prices are good. Customization is VERY nice. And the reviews I see from real normal people on forums are basically all positive
@Hexsense

WR is pretty well known, well tested design now. Lightbicycle Turbo is the latest "performance: unknown" wheel design. Personally I'd vote for Lightbicycle Turbo (50mm or 65mm) to be tested first. It's different from anything else in the market whereas WR has already been a known safe choice that also have many competitors.

My memory of Roval's rationale and how they designed their wide front rim was with a thicker wall. All towards little or no lightbulbing - best aero benefit. Don't know the tire size they recommended for that result. The teams using their tires always seem to be on narrower 26-28mm. There is a trend towards wide internal rims - see Podg at the TDF on 25mm in all road stages. A Zipp original meant for gravel.

Regarding rim width: Lets separate the inner width and external width into two separate discussion. Internal width: There is no reason front should ever be wider than rear. I agree that they should be the same, or rear is wider. External width: Fatter rim seems to be more stable from my test. My idea of perfect wheelset would have rear wheel rim profile to be rounded V shape where it is widest near brake track for aero to weight ratio. But front rim have more bulbous,rounded U shape where it is widest below brake track for crosswind stability. This shape's ideal width is inherently wider than rounded V shape for the same tire width. So, I see why wider front external width than rear can be ideal. Roval front and rear have same 21mm internal width. But external width is wider on the front.

I think most of the comfort needs came from the front. I never had a problem with 25mm tires on the back of my stiff aero bike, but it's obviously horrible on the front. In the end they just go for 21mm internal on back to save weight. I would go for 25/25.

Agree completely on the staggered rim tyre width philosophy! My ideal set would be a 50 ish front optimised for a 25-28 measured tyre and a 65-75 thats at least 33mm at the rim edge, probably even a bit wider, basically a gravel rim lol. Low spoke count front, pretty high spoke count rear.

I have also Drive 65 and they are really good and I love them too. Customer service is super good. But they have the same open hub design as a lot of other wheels with carbon spokes.

How would it measure the turbulence created by everything behind the sensor? You see F1 cars in testing covered in those aero rakes hanging off the back wing and/or half way down the car.

I read there's this rule in which the tire should be between 1.4 and 2 times bigger than the internal rim width for safety reasons. I'm thinking about this in relation to gravel wheels. The internal rim width for gravel wheels is not wider than 26 mm. Why are fabricators not going larger if we are putting 45 mm gravel tires or even wider (if the frame permits it)? Yet for road, we almost have the same internal rim width as in gravel.

@PT how you doing bro? do you have a way of knowing that the products you receive to review aren't handpicked and we would get the same exact thing if we ordered one?

I don’t but with the amount of poor stuff i get sent they clearly are not hand picked! The original crw being a good example, the end caps were way too loose. The new Tavelo ive been sent is a dog too.

@@PeakTorque Fun fact! Tavelo don't have a hand anywhere in the development process of those bikes. They just take a frame from Adapt Cycles and slap a sticker and marketing campaign on them.

@@PeakTorque interaction I had with Joe in the comments on one of his videos: Me: Do tavelo actually do any real development or are they just selling rebranded open mold frames like winspace? Because both tavelo frames were on the adapt website, the attack is gone now but the arow is still up there. So who actually developed that bike? Joe: They develop the frames then offer them to other brand customers, but this time the demand for the Tavelo stuff is so much, they probably wont offer to other brand customers.

Hey peak torque, I got a question. Say if I have two pair of wheels, both are 60mm. But one pair is 1350g and another is 1600g. Which will be faster and why? I believe both have the same aero benefits. But how about “holding speed” and acceleration etc. they say heavier wheel holds speed better due to momentum but what about the rest of the

Thanks. I would always select the lighter ones. Heavier wheels store more kinetic energy but require more energy to accelerate. The stored energy by the flywheel effect is tiny compared to the kinetic energy of your mass + bike.

"Are Wider Tyres a total WIN? The Aerodynamics" kzbin.info/www/bejne/Z5DIZqeigpp6n5osi=EhseLQcdcgAH0bfb. In this, you infer that your Internal rim preference is 21mm and praise the ICAN Aero 35 for having an impressively Aero interface 5000 28 to rim. The Aero 35 is 29mm external, so presumably the 5000 28s measure up 28-29mm. You said you didn't understand the push to wider rims, both internal and external given the overall impact on the A of CdA. However, here you state a pref for 23mm internals both front and back. It's not clear to me what changed - you've not been explicit in any of the content I've seen so far - I'm very new to your channel. Is there something in comfort, aero, cross-wind stability or other that has shifted your thinking in the past 18 months? Am really appreciating your candour and insights.
