Upgrade your SRAM T-Type drivetrain with reduced friction, smoother shifts, and 100% power transfer. The Kolossos ST features an 18-tooth lower pulley (up from stock 16T) and maintains the 14-tooth upper pulley for optimized shifting accuracy and chain retention—essential for XC, marathon, and enduro riders.
Equipped with high-quality stainless steel bearings, the Kolossos ST delivers excellent durability and smooth performance at a more accessible price point.
Ground clearance remains similar to stock cage design.
Fitment: Compatible with SRAM T-Type rear derailleurs including GX, X0, XX, and XXSL lines.
