You should consider a Google spreadsheet that everyone can edit.

+1, good thread are the weights claimed or real? I'm running some KinLin XR-300 rims with Pillar 1432 bladed ti spokes and some Bitex Hubs, how aero do people think these are? 19mm wide rim with a 30mm depth and they weigh in at 1550 grams on my kitchen scales

Reynolds will introduce some new full carbon aero clinchers in 3 rim depth this fall.

The old school was a rim wasn't a true aero rim unless it was at least 38mm in depth so some may not consider your list all aero wheels. :shock:

Just saying. :wink:

why are these wheels so wide? is it purely to run fatter tyres?

wide is in fashion since it was found some wider rim designs have better aero performance than narrower ones, especially if used with the correct tyres, so now some wheels also have matched tyres available

Sorry, I'm not familiar with embeded google spreadsheets. Maybe someone else has some motivation.

Weights are either what is listed on the marketing material, or found on various reviews, forums, or blogs.

Wide rims are the 'fad' because they do show reductions in drag when used with 22-25mm wide tires. Narrow tires have issues with pinch flatting with lower pressures. Lower pressures are preferred to improve ride quality and grip.

The kinlin 300 rims have been tested before. They are obviously better than a Open Pro wheel, but nowhere close to wider rims with a 23mm tire.

I wanted to make some observations on this market information. #1, these wheels are porky. The only wheel that is WW respectable is the MF wheel, and the rim shape obviously needs improvement. MF might have a big success if they made a shallow stubby version of their clincher. #2. The Rolf vigor alpha is surprisingly light considering it's Ti free hub. Seems to test similar to the zipp 101, but I think Rolf should show their compairitive data. #3. The Hed jet 5 is over priced relative to Bontrager and Flo. Obviously Flo is going to have a big impact on the Pre-built wheel market. I'm sure thee are others coming from China soon sine the IP situation is murky. #4. Why did Tony Martin ride a Jet 9 at the world champs last year? #5. Why hasn't American Classic not designed an aerodynamic fairing for thur tubeless/Mg wheels. Wide rim, super light and stiff, would be a perfect base for a fairing.

where have the KinLins been tested before? I've been looking everywhere and I still can't find data on them

I believe the kinlin xr-300 was built into the FSA wheels cited here:

+1. The last white paper from Bontrager I have seen shows 30mm as the meaningful start and around 70mm as the beginning of diminishing returns for a given yaw. Tire width did not make much of an aero difference.
One also could argue that Enve with their recent 3.4 confirm these tests.

You forgot the Campy bullet line and corresponding Fulcrum wheels too.

Very nice list! I will mention that the width values for your carbon clinchers (specifically the Zipp and Bongrager values) are actually the "aero widths". This refers to the widest part of the fairing and not the brake track. For example...

Our rims are 24.4 but our "aero width" is 27.2mm

Zipps Rim width goes from 23.48mm to 25.73mm and their "aero width" is 26.53mm on the 404 FC and the 808 FC.

Regardless... cool list!

Take care,

Given the Enve 3.4 front is 35mm deep, and probably outperforms most 60mm 'aero' rims, old skool is perhaps old hat.

Just sayin' :wink:
