Bigger is faster.



Oversized derailleur pulleys are all the rage these days. Large derailleur pulleys cause less chain deflection and slower bearing rotation. Both lead to less friction and more efficient power transfer.



Main advantages:



Reduced friction while maintaining shifting accuracy.

Kolossos is 3x stiffer than competing products and 2x stiffer compared to the original pulley cage on your derailleur.

Long tooth profile on the lower pulley for better chain retention.

Ceramic bearings in the pulleys for even lower friction.

Choice of three color variants.



Technical specification



The guide is designed for MTB derailleurs XT and XTR 12s.

Does not fit derailleurs other than 12s.

Number of teeth on pulleys: 14 (upper) and 19 (lower).



Category: Derailleur hangers

Type: MTB
