Fork mounted cable stops

[Curt Goodrich]

I'm talking about the ones that seem to be the soup de jour on carbon cross forks. I know Zinn wrote that they eliminate fork chatter. The physics don't make sense to me as to why they would. But I've never experienced fork chatter on my Enve forks. So what do you think? A solution to a problem? A solution looking for a problem? Or what's old is new?

They also help clean up brake dive on one's Mag20.

In my experience they haven't been necessary, but they seem to work fine. Seems like a great way of dropping the stem on a bike with a tall head tube, too.

Curt, I'm going to have to go with the third choice. What's old is new. Fork chatter can be a mysterious thing sometimes. It doesn't discriminate- carbon, steel, short head tube, long head tube, 1", 1 1/8", short pads, long pads, red pads, green pads.......... But the one thing that always fixed it (for me) was the crown mounted cable stop. I would say that if you haven't experienced with Enve, then don't change a thing. I'm really curious about tapered steerers and if they really prevent this. Does anyone have any experience with tapered steerers and fork chatter?

Is anyone using tapered fork on cross bikes? Fork chatter while braking?

I've been wondering about this as well since both of these bikes have front brake chatter.



I've tried various brake pads and the only thing that works is a little bit of reverse toe.

This is what I'm trying now.



It's 5/16" round bar that passes through a hole in the crown for a lot of brazing surface area. I'll build the bike up before paint for a test and if it doesn't work I'll chop it off.

P.S. Make sure your crown race cutter clears the hanger, I almost forgot to check.

Tom Kellogg had a really robust looking one in FNL last week. I would just poach the picture, but it's in this post

Clicking is overrated. I'll bet the farm this is the end of your chatter problems.

i don't experience (nor have i ever...) all this shutter that gets posted about every season, but i do
think that having the part on the fork is more elegant than using a clamp from problem solvers atmo.

A season on it. Not a lick of chatter or shudder.

Great report Tim. I'm more than sold on this.

Tim-

Is that round bar or tube? 1/4"?

Thanks, Joel

Joel, 4130 tube inserted through the fork and brazed at front and rear of the crown.

[Boedie]

Richard, If I recall properly, you chop your front brake pads down. Is this true for all your cross bikes?

Nice... Are those the TRP 9 or 8.4's? Has anyone here tried the 8.4's?

[Clockwork]

Finally got this all built up and took it for a spin. Great brake performance and no chatter.

[Eric Estlund]

Sorry I missed this post- those are the 9's. The 8.4's were not around when I built that up. The 9's work great.

Does anybody worry about cable pull or the lack thereof? It seems most of the examples I'm seeing have very little cable travel available. I'm sure there's plenty when all set up properly but with a little pad wear it looks like the barrel adjustment will allow for the straddle to hit the hanger in a hard braking situation. Of course, with pad wear one could re-adjust the pads and straddle but in my world that would get tiresome. I'm not an alarmist but I also think anything that could possibly interfere with braking is problematic from a liability standpoint.

[Clockwork]

I didn't consider that. I just considered I'd set it up right and service it as necessary since it's for my father-in-law. Your point is something I'll remember for the next fork though.
