so i bought a specialized rockhopper comp disc on fleabay, and its in need of some light work, as i expected. First real mountain big since an old GT i had a long time ago, i think it will be fun!

biggest trouble i am having is trying to get the cranck arms off, i have a bunch f puller sets for automotive stuff, i am thinking as long as i find something to actually fit on the end of the BB then just using that puller will work. anyone tried this?

next question, the cranks are shimano fcm 442 on the left arm i seem to be missing the center bolt that hold the arm on, even though the arm doesnt have any issue staying on, as it doent come off easy. is there any way to get this bolt by itself? is it something the lbs should have?

one other question, the fd is a clamp on unit. its dirty and im thinking about taking it off to clean it, but im worried about lining it back up if i do take it off. Is it hard to do? or is it a ball park thing anyway.

thanks guys,
