I have a 07 Diamondback Response Sport and lately i've been having a few issues with it.
The main problem is the bottom bracket.
It keeps coming loose, and I do not know why. I checked the threading and nothing is stripped or anything like that.
The bottom bracket itself isn't all that great to begin with i know (it's basically a department store bike anyway). But its a Truvativ X-flow crank. It has those stupid tapered bracket ends. If any of that helps.
any suggestions or solutions?
