(I clicked "Reply" to this thread, but to a conversation unrelated to my question...picking up on David's name - anyone know how to add a comment to this thread without replying to someone specifically?)
Anyway - on to my real question about my Magura brakes. First off...LOVE THEM! Woot. I can stop on a dime, but must be careful not to a) eject over the handlebars, or b) wear holes in my rear tires if I lock things up. These are fantastic. Rode mountain bikes for years with hydraulics - from Magura - and am really looking forward to low maintenance, solid braking.
I have a set of HED Stingers on the bike - Stinger 9 FR on the back and a Stinger 6 FR on the front. The wheels are 28mm wide - specs here
http://www.hedcycling.com/...efault.asp?content=9 The problem is that the brakes are REALLY close to the rim. A little closer on the rear than the front, and it's the rear that I am worried about. I don't want the brake pads rubbing, and they don't when pedaling on a straight flat road, but when up in the pedals or pushing hard when climbing, there is some minor flex in the wheel (in any wheel) and I am concerned that it is going to touch the pads.
I have backed out the pressure point adjustment screw all the way, but even by manually pulling the brake calipers apart, I can't spread them much more.
So...what's the limit on these brakes? Are 28mm wide rims pushing the limit? Do I need to shave a mm or two off of the pads to get some extra clearance in there? I don't think that this has anything to do with the bleeding of the brake system, or too much fluid in there - that doesn't make sense to me. These were installed at a LBS, and the mechanic has done several P5's already and knows his stuff.
Thoughts anyone? ...before I take a file to the pads?
