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 transmission.

Main advantages:

Reduction of 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 holding.
Ceramic bearings in the rollers for even lower friction.
Choice of three color variants.

Technical specification

The leash is intended for MTB derailleurs XT and XTR 12s.
Does not fit derailleurs other than 12s.
Number of tubes on rollers: 14 (upper) and 19 (lower).

Category: Derailleur straps
Type: MTB
