Hi everyone,
Im still playing with my canti problem ,its much better but no cigar yet .
heres the scoop.
Surly XC with road levers/wheels, the brakes That I purchased with the frame are tektro oryx .
well after setting them up I had the CANTI CURSE ,squeal and chatter from Hades and no matter
what I did it did work well , and the only thing that worked half azzed made the brakes useless.
I tried everything!! all the toe-in tricks , Sheldons tricks... to no avail. Hmm never had problems with big fat MTBs and cantis but, fat rims and levers that pull lots of cable are agreeable to low profile cantis..
I did notice that if the pads (either brand ) were right up close to the brakes they were much better but, with the pads that close to the brake there was not much leverage left on the arms (almost vertical). I also noticed the pivots on my set of oryx were pretty darn sloppy (loose) and that could for sure add to the problem. The tektros only were quiet when not used or so much toe in that I couldnt use them.
I found a pair of NOS Paul stoplights at a LBS and put them on my front and for the most part all the problems are gone, BUT again even on this better (much better) made brake I have to keep the pad as close as possible to the brake.
the further the pad posts/studs are exposed the worse the problem though with the Paul stoplight it was much less a problem (but not good) than with the Tektro which is real bad. !
with the above scenario in mind It seems to make sence that with skinny road rims /levers that wide profile cantis should be the right choice , at least on the front?
It seems to me that with a wide profile canti I could snug the pads pretty darn close to the brake (less post/stud to flex / vibrate) and still have plenty of Arm angle left to pull cable even if I position the pad a MM or two from rim.
with low profile cantis if I snug the pad to the brake itself to stop the squeal /chatter and also move close to rim then braking power is gone as the arms are almost vertical.
Sheldon Brown mentions this on the harris site But It didnt sink in with me untill after I ordered my brakes. sheldon mentions the fact that with low profile brakes the pads have to stick way out on the posts to allow enough leverage thus causing the brakes to squeal vibrate ... hence the tradeoff of low profiles.
In final Im wondering if My assumption of using a Paul neo retro or similar Wide profile with everything snugged up will solve most of the trouble that seems to haunt the new low profile cantis that are often used with road components.?
your thoughts please.
have a great ride
