Kogel’s latest round of anodized alloy pulley wheels come in 14-tooth sizes to fit the latest round of Shimano wireless derailleurs. And they come in six colors, letting you cage a little bling while gaining watts.

Fitted with Kogel’s Cross Seals to keep grit and dust out, they’re available hybrid ceramic bearings – meaning, ceramic balls with a hardened steel race. Kogel does offer some pulleys with full ceramic bearings, just not these. Yet.

The pulleys themselves are cut from 7075 aluminum, which last longer than the stock plastic pulleys. Kogel says they don’t affect chain wear.

They’re compatible with all of Shimano’s new wireless Di2 12-speed MTB and gravel derailleurs, including XTR, XT, Deore, and GRX. MSRP is $224.99 for the pair, available in black, blue, red, gold, raw, and purple.
