I have been watching my front sprocket slowly curve out the grooves over the last month and today it finally slipped. Luckily i won a chain thanks to slick's contest, now i just gotta get the sprockets. I was tryin to take the axle apart today and it wouldn't budge, 1st is it a counter clockwise thread, if not, any tips to loosen it up? Also what do you guys use for wrenches, Pipe wrenches or chanell locks or big ass wrenches?
