Someone in the thread wrote that the rear hub/freewheel sound is quite loud - with the "own hub system" that supports carbon spokes.

Peter told me that if I want to go with carbon spokes I will have to got with their own hub system - DT Swiss, Novatec, Extralite won't work.

Can someone record and upload a video that shows the noise and share it here?

I got a set of wheels with 54t ratchet, and to be honest, the volume is much lower than I expected....54t makes a higher-pitch noise compared to 36t.

Also, you can influence the volume of the noise by adding or removing grease....so I would not worry about the noise level on XM Carbon Speed wheels...

Hi all,

short feedback on my wheels received from Peter a couple of weeks ago and mounted on a Tarmac SL7.

They are 50mm front / 60mm rear (D50CU-31 and D60CU-31), 54t ratchet, 3.8mm carbon spokes, 20/20H, UD paintless, rim 24mm inner/31mm outer so perfect for 28mm tyres. With this rim, my 28mm tyres have 30mm width.

One of my requirements when getting those was not to loose in comfort vs my previous 50mm wheels with metal spokes, as well as good cross-winds stability (Peter recommended 3.8mm spokes for that purpose).

Upon receiving them, I started regretting that I did not get Sapim CX-Ray spokes and 36T ratchet (for long-term usage - I spent too much time documenting myself  ), but after having rode them on 2 occasions, I am really happy with my choice:

- I did not loose in comfort with the carbon spokes and higher rim profile
- I see many people say that 36T ratchet is very suited for road use, but I actually find the 54t really nice to ride....it makes for a very comfortable ride, i.e. when re-starting to pedal, the transition to the hub "biting" is very smooth, I really like it

Aside from the ratchet and from not losing in comfort, the main difference I can feel is the acceleration vs my previous 1590gr wheels. These feel like they respond right away.

But otherwise, I'll be honest and say that I did not feel huge differences....but when checking my Strava, the data tells me otherwise ! I'm not in great shape currently, yet I'm having the same top speed and average power than during the season....I can't wait to get even more acquainted with those wheels ! 

That's my 2cents  Happy customer, good job Peter and keep it up !

Hi,

how are you guys finding the quality of the HBR17 handlebar compared to other manufacturers ? I'm quite keen on the design and am tempted to get one, but it's low price compared to the competition makes me wonder what to expect quality-wise....
