Anyone else run into this with a small frame?
Hmmm...I hadn't noticed that the 50/52's had the sidepulls. Thanks for mentioning that. Regarding shudder or vibration while braking, the only times I've gotten that - not related to wet-weather braking - are when using brand new pads on a new rim. I would actually take a scotch-brite pad or emery cloth and rough up the pads a bit. You should find that it lessens significantly as your rims get a little roughed up - a good trail ride on dusty trails usually does it around these parts. The only other thing to check would be that the hub has no excessive play and that the wheel is firmly tightened down. Also, you would want to confirm that both pads are gripping the rim at the same moment. hope that helps, - Jim -- Jim Edgar [email protected] Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Your Photos are needed! - http://www.cyclofiend.com/guidelines "I thought the idea was to waste the rest of our lives together.." -- Cyril, "Breaking Away" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
