This is a brand new 2008 Trek FX 7.5 with Bontrager SSR wheelset. No matter how much clearance and precise centering of the rear wheel, there is still brake rubbing when I m on the bike. I weigh 185 lbs. The brakes are set almost loose enough to run out of caliper pull--approximately 1/8" clearance on both sides of the rim. The wheel can
easily be pushed off center, by hand, laterally, about 1/8". Is this a common problem with Bontrager SSR wheels? When I put on another rear wheel(inexpensive Shimano Nexave C500 w/ Sun CR-18 rim, 36 spoke, laced 3x) the problem does not occur. I would not have thought that 185 lbs. would be too heavy for the Bontrager SSR wheels. Is it common for these lower level Bontrager SSR wheels to come through needing additiional tensioning to make them laterally stiff enough not to give with me on the bike? Will this be a recurring problem, or should my LBS be able to fix this. Advice and comments appreciated. Thank you.
