Part# BB-36

SunTour Cyclone bottom brackets were produced in the 1980s. The cups have seals that generally keep water from getting into the bearings.

SunTour bottom brackets were made to JIS (Japanese Industrial Standards). That means the taper matches Sugino and is very close to Campagnolo. Most users find all three interchangable.

Ours is in excellent condition with one small, slight imperfection in the adjustable cup bearing surface

You can see the rubber seals that protect the bearings
