Tange Square Taper 68mm Bottom Bracket

This is our everyday bottom bracket, and has been for the last decade. The alloy version light but tough, with sealed bearings, while the steel version is heavier but more affordable. The axle is CrMo steel in both cases. All you need is a regular Shimano-style BB wrench and some grease, and you're good to ride.

• BSC threading (1.37x24TPI)
• JIS taper (that's the normal one, not the track or Campy one)
• 103mm for track cranks, 110mm for a road double or the Bassi 1x, 118mm for a Bassi Classic double or a road triple. These are just guidelines, you'll have to check for yourself or write in if you're not sure.
• Shell width: 68mm
