Hey
The bearings in my profile mtb cranks haven't locked up completely but if i let them sit for awhile they do take quite a force to get them moving again. I think the bearings have been in there awhile and probably need to be replaced, however I dont have the time before (or money to replace them) mt snow. Can anyone tell me if theres a way to take out the bearings and grease/clean them? thanks.

Sure, just use a razor blade to gently pry the rubber seal out of the bearings.

Count the ball bearings as you take them out, wash them, wash the bearing races, , dry everything, count the bearings as you put them back in, and apply some grease. Then pop the seal back on.

Just be very careful taking the rubber seal out since if you damage it, you're going to need new bearings. Also, if any of your bearings are actually toasted (broken, cracked), you can still ride but don't be suprised if your bearings freeze up sometime during your Mt. Snow race.
