The latest brake in my quest for stopping power...(7 posts)

The latest brake in my quest for stopping power...Steve_O

First it was the Avid's but the squeal finally drove me to sell them. Next it was the Radius brakes but the lack of stopping power (In comparison with the Avids) bummed me out.

Just curious if anyone had any experience with Suntour Canti's. Got these for cheap in an eBay auction and they will be going on the Kelly Knobby X soon. Any feedback would be appreciated...

I run Avid's & know what you mean by the squeal. I replaced the stock with the Rim Wrangler 2 pads, on my front brakes & they are much better. Time for the back brakes now.
I have to admit though, I have to clean the brakes after every off road excursion, especially when muddy. If I am out there & there is mud on the pads ....

Third set of canti's hey? Maybe canti's aren't the answer. Ever tried V-brakes with Travel Agents? Might end your expensive, time-consuming quest. Just a thought.
Well it might happen eventually...Steve_O

I've used V's on my MTB's quite a bit (both Avid and Shimano) and that might be the next option if I'm not satisfied with the Suntours.

I've probably been holding out from the V's too long simply because I'm not too excited about the cam device that I'd need to use.

I've owned several pair of XC Pro cantis. Back when cantis were all that there were, I liked them better then the Shimano offerings.

If you want more canti braking:

Scott SE brakes seemed to have great stopping power, but were a pain in both setup and maintanence.

My Onza cantis seemed to do very well for me, but I've heard that others hate them.

Depending on how you set up the straddle cable, you get different feels, try altering the height (lower = stronger, but with less mud clearance). Back in the day, I used to put the bottom of my cool, blue anodized, Tri-dangle just above the bottom of the fork crown. I figured that the bottom of the fork crown was going to limit my mud clearance anyway...

Try playing around with the brakes, you'll learn something. Adjusting old cantis is a lost art anymore.

Therein lies the real advantage of V's. Any moron with a 5mm allen can make a V brake stop really well, at least 99% as well as the shop mechanic.

Give that moron a set of cantis and he'll come up with poopoo for braking. Done properly, cantis have 90% the power of V's with far superior feel and modulation. Done wrong and you get no power and no modulation.

Almost any canti can give you great results, barring the Radius brakes, and you'll even get good results from them. I've actually had the best luck with shimano XTR cantis, though any similar brake will work really well, as in your Suntours. Set the pads out from the brake arm near the end of the post. This gives you more of a medium profile, rather than a low profile brake. This gives a lot more lattitude in how high to set the straddle cable. You can set it low, which will probably give you too much power, in which case you'll overpower the tyre to ground patch and lock up too easily. Mine are about 3" above the rim. Gives me plenty of power, great feel and enough slack to get the tyres off easily.

Sheldon Brown's website and the fact that I could never get my Avids to stop squealing really got me going on the whole brake topic...

Based on what I've learned here it seems that the Avid squeal is more a problem with the design of the brake more so then my tuning skills (heck... Even Rivendell stopped carrying the Shortys because of the squeal).

With the Radius Brakes I started reading what Sheldon had to say about high profile vs. low profile brakes which seemed to make sense. After going through multiple straddle cable changes and changing pads the Radius brakes came off and the Suntour brakes went on yesterday...

You are so very correct in that any idiot can tune a V-brake however its probably the retro grouch in me that keeps me fiddling with these canti brakes...
