SEAL OPTIONS
Cross Seals (Green)
Road Seals (Blue)
We always encourage and recommend the use of Cross seals where possible.

These pulleys spin on Grade 3, Abec 5 hybrid ceramic bearings. The same bearings as our bottom brackets. Choose road bearings for lowest friction on road bikes or cross bearings if durability is key (that's for you, cross and gravel racers). The wheels are made of aluminium, which will make them more resistant to wear in muddy conditions.

Out of the box, these pulleys will fit on:
- Shimano Road 10sp & 11sp derailleurs
- Campagnolo 11 speed
