Replacement freehub bodies to fit e*thirteen hubs. Replacement drivers are available for our newest line of wheels: Grappler, Sylvan, Optimus, and Piedmont. Offered in Sram™ XD™, Shimano™ Microspline™ and the traditional splined 10/11 speed Shimano™ HG driver.

3-Pawl / 6°: Grappler DH, Grappler Enduro, Grappler e*spec Enduro, and Sylvan e*spec Wheels intended for gravity disciplines or e-MTB use, come equipped with 3-Pawl drivers (or freehubs), in which all 3 Pawls engage simultaneously. This provides 60 POE or a relatively low 6° engagement and high levels of reliability in high torque and heavy impact environments. It also minimizes the pedal kickback which is more pronounced in bikes over 150mm travel, especially during high-speed descents on rough terrain. 

4-Pawl / 3°: Optimus Trail, Sylvan All Mountain, and Piedmont Gravel Wheels utilize a 4-pawl driver, in which the pawls are clocked to engage two at a time. This doubles the POE, to 120 points of engagement with the same robust 60T ratchet ring, or 3° engagement. In All Mountain, Trail, and Gravel applications, this provides long-term reliability, with the added efficiency to optimize long days of climbing and descending. With shorter travel bikes, pedal kickback is a less common problem, allowing a greater focus on efficiency.
