Maple offers two upgrades to DT Swiss's standard ratchet that comes on all hubs. All DT Swiss hubs come standard with the 18t ratchet which provides 20 degree engagement. If you prefer a faster engagement, the 36t upgrade offers engagement every 10 degrees and the 54t upgrade offers engagement every 6.6 degrees.
NOTE: This option is only available as a service on new wheel purchases. We do not ship the ratchet kits individually.
