Bigger is faster. Large derailleur pulleys cause less chain deflection and slower rotation of the ceramic bearings. Both lead to less friction and more efficient power transfer. Tired of your derailleur holding you back? The Speed Kolossos for SRAM XPLR breaks free from factory limitations with low-friction ceramic bearings and a stiff aluminium cage that shifts instantly and without hesitation.
Main advantages
- Reduced friction while maintaining shifting accuracy
- Kolossos is 3x stiffer than competing products and 2x stiffer than the original pulley cage on your derailleur
- Long tooth profile on the lower pulley for better chain grip
- Ceramic bearings in the pulleys for even lower friction
- Choice of two colour options
Compatibility: SRAM XPLR AXS gravel derailleurs.
