It picks up before you think about it.
A 60-tooth ratchet with five pawls gives AR-01 a 6-degree engagement angle. That matters when you accelerate out of corners, restart after a climb, or keep pressure on over uneven roads.
The hub stays mechanically simple and serviceable, while NTN full-complement bearings keep the system smooth under load.
Standalone hubs, or the heart of a full wheelset.
Buy AR-01 as a hubset for your own build, or use it as the hub platform for Polaris, Polaris SL, Zenith, or a custom Ascent wheelset.
