So I've been having a creak for god knows how long. Happens when I put more effort in, and happens baaaaaaaaaaad when off the seat.
Was pretty certain it was the bottom bracket, so no biggy, I bought a replacement.
But before I put it in, my boss suggested dropping the front wheel out, giving the drop outs a clean and put a tiny bit of grease in there, then put the wheel back..
Well bugger me, absolutely perfect. Whisper quiet..
Least now I have a spare BB at home
