I have been building a 2009 SE Lager (The white model) for the past few months off and on. I'd like to upgrade the crank set / bottom bracket. I am not near the bike so I can't remove the BB to see what the size is. I tried a search here but was not successful. Any of the specs I have pulled up online say Euro Cartridge Sealed Bearing. Any help anyone could offer would be greatly appreciated!
