Hello Dirk The problem is, I do not have enough space to fix the BB close to the tire (3 to 4 cms)... the BB shell I have is 7,5 cms wide, the tire is 6. Raising the BB about 4 cms helps a lot, but then I have problems with the chainline. That's where I stuck. Cheers Jaime Hi Jaime, which is the problem when using 26" & fat tires?
