Hi all, first time poster.

Having a bit of trouble with my rear wheel, notably whenever I try to skid/put any major force down on the cranks, like a hill start for instance. It feels like the sensation of the wheel losing traction and skidding (obviously not actually skidding though) or even the cranks coming lose in the BB. I assumed it was just the nuts holding the wheel in the drop outs being loose and only a case of tightening them, which I've tried but to no avail. Any suggestions as to what it is/has it happened to any of you before? I'd investigate this further myself but I'm away from my bike at the moment, thought that getting a second opinion would be my next best option so I have some direction when I come to tackle this myself. Cheers guys.
