Knight IMPEL Ratchet Drive 28H hubset 12×100 / 12 x 142 Lightweight 400g

IMPEL Ratchet Ring Drive System

Available as an upgrade option from our pawl drive hubs, IMPEL refers to our new 24T ratchet ring driver compatible with select hubs.

Unlike a traditional pawl system, Alexrims’ ratchet ring provides more positive engagement with the hub for improved power transfer.

Additionally, ratchet ring systems have increased lifespans and improved wear characteristics making them ideal for aggressive riding.
