I'm planning to convert a mtb to 650b and think to lower the crank by using an eccentric bottom bracket for standard frames like the "exzentriker" or this one: http://forums.mtbr.com/singlespeed/another-eccentric-bottom-bracket-standard-frames-473562-post5144832.html
Have anyone tried this? How many mm can I lower the crank?
