So when I get up to speed(fast or max for the gearing) I feel this weird what feels like loose crank or pedals but they are both tight. So then when I started to play with the crank and spun it forward and then back I noticed that there is some play in the bottom bracket. Its tight, the bottom bracket but it has some play from forward to back. So my question is, is this how some are or is something wrong with the bottom bracket, can it be tighter or have no play? Oh I have a stock SteamRoller fixed.
