I am a borderline clyde (6'5"/200 lbs) on a new GF Paragon (29er). I had the LBS swap the OEM 160mm Juicy 5's with 160mm BB7's based on the reviews of those two brake systems on this site. This is my first bike with discs. I have been riding the bike for a few weeks now and followed the recommended brake-in procedures.
I find that these brakes have pretty good stopping power. They are much better than the V-brakes on my old bike. However, while riding this weekend, I really clamped down on them to see what they would do. The rear brake seems perfect. I can clamp down on the bak wheel and hold it just shy of skidding with no problem. The front brake provided a pretty good clamp down as well, but was nowhere near locking. I tried tightening the calipers (inboard and outboard) by one click each. I got a little more power, but I also got a small amount of chatter (or shudder) in the brakes.
I am not looking to do a daily faceplant, but, based on what I have read here, it seems that I should at least have the potential to endo.
So here is my question: Is the combination of 29" wheels and a 200 lb rider too much for the 160mm rotors? Should I look at upgrading the front to 185's, or are my brakes just improperly adjusted?
Any insight you could provide would be most appreciated.
