    09 CORSAIR MAELSTROM ...need help!

    whats up guys.. looks like these two pinch bolts from the clamshell around the bb jumped ship somewhere along my travels..
    ...seemed to have been working fine, just visually noticed them missing... I've read that they were all initially overtightened from factory and needed to be backed off a bit.. guess I backed mine off a bit too much! oops!
    ...can someone help me figure out the size and length so I could get em replaced? thanks!



    i want to post more but i can't stop riding!

    I'll stick my bike on the stand in the morning and let you know the size.

    Cheers,
    Ryan.

    the stock bolts in mine are 30mm long (including the head) and take a 5mm allen key.

    thead pitch looks to be 1mm - but I don't have a tread gauge in front of me so Im just using a ruler.

    hope this helps.

    M6x25mm (you don't include the head when measuring cap screws) and yeah, the pitch is 1mm. These shouldn't cost more than a few cents each at the store.

    I was the one that thought they were overtightened in the factory. Backing them off a tad let the bearings roll more smoothly. In hindsight, i'd say the real problem is the quality of the bearings. With good ones you can tighten em down normally.. with those cheap chinese ones, they just go bad regardless.

    Now I gotta take the whole damn thing apart and clean it so I don't just clamp down on all the dirt that's probably in the shell.. I might as well replace those chinky bearings while I'm at it.

    Those large bearings around the BB go real bad real quick, get those outta the way. The rest of the bearings aren't as big a deal imo, and don't get as bad as those large ones.

    Using a healthy amount of blue loctite on the bolt threads will allow you to back them off 1/4 or 1/2 turn so you don't crush the bearings. They should stay put just fine.

    Local bearing shop. He had Japanese and French bearings.. according to him, much better than the generic Chinese ones.
