Bought a 1998 Trek 520 on ebay. I am learning (miserably failing) to wrench. On other bikes, I overhauled the front and rear hubs. I took the chainrings off and thought I would check out the bottom bracket while I changed the gearing to something a little better for touring. Used the BB2 and a large wrench and the Blue Book. Broke some kind of ring on the non-drive side and am waiting for help when I see the boss man. (He won't be happy) Will he be able to use a pipe or something, or do I have to go to the lbs and have them drill it out??? I would rather bypass the husband, if he really doesn't have to bail me out. Then again, I don't want to guys in the bike shop to see what I did either.

Chainrings. I ordered some that fit both 130 and 110 bcd (heavy rings!). The 74 bcd 24 tooth granny went on without a problem. The middle 38 tooth went on without a problem. The outer ring 48 does not sit in the step down (?) of the spider of a Shimano 105. Because the rings fit both sizes bcd, there is a lot of extra metal. Do I have to send this back to Harris Cyclery or did I order the wrong part???

Thanks, Debbie
