SunTour XC Pro English bottom bracket with SunTour Grease Guard System. New old stock, $100.00/each

We have several, all English threaded: 1.37 x 24

With these spindles:

68mm x 127.5 (we have four of these)
73mm x 130 (we have three of these)

This bottom bracket uses Wilderness Trail Bike's "Grease Guard" system. The crank bolts are hollow, allowing grease injection into the bottom bracket and out ports on the spindle. The dust caps have rubber seals. Neat!

These were produced in the 1980s.

SunTour Cyclone bottom bracket. 68mm spindle w/ English threaded cups (1.37 x 24)- $60.00

Part# BB-36

Spindle length: 113mm

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
