    Default More CX brake chatter woes...

    Ok, so since I started raceing CX four years ago I've never had brake chatter issues while running cantis off a steerer mounted cable hanger. Two bikes ran steel forks, and the third a carbon fork with aluminum steerer. All the while, I've used aluminum rims.

    This year I've finally got my CX bike set up dialled in a way I think is optimal, at least on paper. I'm running an ENVE 1 1/8" fork and Paul's touring cantis with a 35mm deep carbon tubular rim. Unfortunately, ever since I switched to the carbon wheels, I can't seem to eliminate the chatter, and it is indeed violent at times. This has been the case with both Swiss Stop Yellow King and regular black pads, toed in anywhere from a bit to a lot (2mm). I've also raised the cable hanger to reduce power.

    I know others who have used the same rims without issues, but they were on Specialized tapered forks, and some might have even run cable hangers. The ENVE fork is not drilled, so it won't take a hanger. My steerer mounted hanger flexes a tiny bit, so I might try a shorter, stiffer one. My team-mates with the same set-up are going through the same issues.

    So here's the question: are carbon rims generally going to be a royal pain in the ass on CX bikes with cantis? Does anyone have a tip on pad choice that might work better, say, Kool Stop's carbon pads? I know a mini V-brake is an option, but I'd rather exhaust other options first. I'm starting to wonder whether the RGM/Sachs team uses aluminum rims because they are simply better?

    Ruckus components can put a fork mounted hanger on there for you.



    Don't really know about the carbon wheels thing though, that's new to me.

    End of story.

    Nice. New product to me. That is perfect.

    Msurch - Myself and everyone and his brother has been thru this. For me the answer is live with it. The really annoying noise and chatter is really only an issue in training. When you are racing or just training super had it does not matter esp. with some dirt or mud on the rims. I'm resolved about that with my SpeedVagen setup. I've got an disk CX bike in bound and I'm a tall guy so that's my answer. For you, that low brake hanger will cure it if you care to go to all that bother.

    Wimpy steertubes/forks are to blame, but the fork mounted hanger is one viable solution.

    I've simply gone to bikes with beefier forks utilizing tapered steertubes and have had 0 issues. FWIW: Blue Norcross frame/fork (large), Avid Shorty Ultimates and Kore Race+ brakes, SwissStop yellows, Edge/Enve rims (as well as various aluminum rims with SwissStop GHP pads).

    If you're going to run a straight 1.125" fork, especially with taller headtubes, I think the fork mounted cable stop is the best way to go.

    Wow, this is a solution that never occurred to me. That looks fantastic!

    TooTall, I get your point, and I think you are right about this being more of an issue than actual racing. Sunday's race wasn't bad, but at the same time, I lacked confidence to go into corners hot and scrub a lot of speed late. That's my style, having come from an mtb (DH, no less) background, so I can see how chatter will bug me more than a smoother rider. I'm going to keep working on it, and consider sending the fork to Ruckus over the winter. That's an elegant solution.

    Agreed. After the season is over and I've ducked out of an sufficient # of races I will likely send my fork for retrofit.

    Try "heeling" your brakes in, instead of toeing them in. It sounds crazy, but every now and then it's what works. Also, make certain that all of the glue is off the brake track. That tends to make things pretty grabby and it leads to the chatter effect. Goof luck.
