ENVE Straight Pull Hub

INNERDRIVE™ represents the pinnacle of bicycle drive mechanisms. Oversized steel ratchets are positioned inboard and over the bearings to reduce stress on the axle and bearings while ensuring positive, reliable engagement

As firm believers in the benefits of a ratchet system vs. a pawl system, ENVE set out to deliver
their first 100% ENVE designed drive mechanism, INNERDRIVE™. By positioning the ratchets
and bearings closer together and farther inboard, axle stress is reduced while bearing life is
prolonged. The ratchets themselves are made from a proprietary hardened steel alloy and
oversized to 42 mm in diameter, allowing for a broad range of tooth counts and engagement
options to fine tune the hub to a rider’s needs and preferences. Elite level road racers may
prefer the lower rolling resistance of the 40t ratchets, while off-road riders traveling technical
terrain may opt for the higher engagement delivered by the 80 and 100 tooth options. Key
benefits of the INNERDRIVE™ Premium hub include:
• Ratchets deliver zero-flex 360° engagement for maximum drive efficiency and reliability
• Four Engagement Options: Interchangeable ratchets allow riders to tune hub
engagement to their personal performance needs. Whether it be maximizing efficiency,
response, or reliability, we have a solution.
• Ratchet options include: 40t/9°, 60t/6°, 80t/4.5°, and 100t/3.6°. All road/gravel hubs, SES
and G Series wheelsets will come stock with the 60t ratchet.
• INNERDRIVE™ System licensing opportunities are available. Please contact ENVE for
