how do i know if i've got a loose bottom bracket?
i feel a sort of clunk and hear a dull ping once in a while when i lay hard on the right crank of my Crosscheck. it's the same thing i experienced a few years back with another one of my bikes -- a Long Haul Truker. when i brought the bike into the LBS that had assembled it, they said the BB had "worked loose."
this is a new Crosscheck which hasn't been adjusted since I picked it up. i would take it back in, but i'm pretty busy with work for the next few weeks.
