Recently I bought a set of Rail 34 custom built by Ergott. It's a 20 front radial and 24 rear 2X both side, laced with Sapim CX-Ray to a Alchemy Elf front and Tune Mag170 rear with DT Aerocomp on drive side. Final weight came up to 618g front and 770g rear, total being 1388g,
Anyway, enough with the specs and down to performance. So, I can't really compare braking to any other carbon wheels, let alone the Reynolds mentioned, because this is my first carbon wheel set. Though, I can compare to a set of Pacenti SL23 that I've built up last year. Definitely better braking performance than my Pacenti SL23, even though it's an aluminum brake track, but that's definitely due to my Dura Ace 9000 brakes compared to my Planet-X brakes. Can't say that's a fair comparison, but I can stop faster and lock up my rear wheel faster on the Rail 34's. As for crosswind, boy are they invisible to it! I can still feel a bit of it with my Pacenti's, but with the 34's, nothing!
On a side note, I'm surprised that Dave did no post the following articles concerning brake track surface temperature when dragging the brakes:http://www.novemberbicycles.com/blog/2014/7/15/get-light.htmlhttp://www.novemberbicycles.com/blog/2014/7/28/the-carolina-swing-part-1.html
Let's add a video too:https://www.youtube.com/watch?v=VyzL8iHJ33s
Since Dave isn't advertising their own testing articles, I'll do it for him!
P.S. Love my new wheelset! Was slightly concern with the brake track's clear coat until Dave's post.
