|What makes a BB a TRACK BB?
ON my Trek fixed gear the spindle is around 115mm long I believe. But when I switch to my LX sport cranks I want to get a sealed ultegra quality BB. Iam pretty sure that with the Sport LX cranks and a 113mm spindle, I wont have much trouble with chainline.

|You can use a sealed road BB on track cranks and visa versa. A lot of people got fed up with the adjustment problems of the Dura Ace road BB and switched over to the track BB(sealed) to use with their road cranks. Spindle length for chain line more important.|

|In the loose ball days, track BB's did not use grease seals because they were used indoors and stayed clean without them. This allowed a bit less drag. Today's sealed cartridge track bearings are safe for road use as they are sealed. I will say that for some reason the modern Campy Record track BB spins better than the modern Campy Record road BB, at least in my experiance.|| |
