XC Pro

Brand: SunTour

The flagship SunTour mountain bike rear derailleur of the early 1990s, positioned above Deore XT in a bid to reclaim the high end of the MTB market from Shimano. Prized by collectors for its high-gloss finish and sealed-bearing jockey wheels, it lost commercial ground to Shimano despite strong engineering.
