I believe this is just break squeal as I don't feel any vibrations when I stop.
I have been meaning to try a different rim, that would be a good test. I currently have a CR18 on the front and I think the squeal is worse with it then with the stock rim that came with the bike. There is no play in the brakes so the bolts are OK. I have a good mechanic and he has minimized the squeal but it always creeps back in after I get a few miles on the bike. I think I will go back to Kool Stop pads as they have been the best. I have some nice looking IRD cantilevers on my tandem another set for the Quickbeam may be in order. And perhaps a new front wheel if a different rim proves to be quieter. Thanks for the suggestions. I love the bike. If I could just get the squeal under control it would be perfect.

I use salmon Kool Stops and don't toe in excessively. Still running the Shimano canti's which came with it. I have a slightly non-standard stem mount for the brake stop. (last photo here - http://www.cyclofiend.com/ssg/2006/ssg017-cyclofiend0206.html ) If it's brake squeal rather than shudder, then I don't know if it can be addressed by changing the brake stop - there have been a number of discussions (mostly in CX threads) about flexing cable stop mounts causing unwanted shudder under hard braking. I'd pop a different front wheel in there, just to see if it's related to the rim. Especially if you are getting the same results from different brake models. I ran some Avids on a CX bike, and do recall them being noisier - maybe something in the mount causing them to flex away - essentially undoing the toe-in - as you are moving. Any chance that the brake mounting bolts are bottoming out before they completely tighten the brake? You should be able to detect fore/aft play in the brake if that's the case. The other thing to do is find a shop who has the Wrench (mechanic) who knows how to deal with canti brake setup. Most don't. Pay to watch them work on it and ask some questions. Sorry not to have a great, all-encompassing answer for you... - Jim On Tuesday, May 13, 2014 7:13:24 PM UTC-7, LAP57 wrote: My Quickbeam is my most used bike but I have suffered with front brake squeal since I bought it about 8 years ago. The original Shimano brakes may have squealed the least. I have also tried Cane Creek cantis and currently have Avid shorty 6's on the bike. The current brakes may be the worst. I spoke with Rivendell and they feel the issue is brake related and not an issue with the fork. I took a look at the Quickbeams on the Cyclofiend site noticed that many had high profile cantis. Has anyone cured the squeal by going to high profile cantis? Any recomendations? Paul does not recommend their high profile cantis for road bikes so I have been looking at Cane Creek and Velo Orange brakes. Any thoughts on these? Any other options? Thanks.
