Optimus Sidekick Pro Flux Carbon Trail Rear MTB Wheel

Optimus Sidekick Flux Pro Carbon Wheels strike the perfect balance of lightweight, comfort, and performance for Trail riders looking for the very best.

They feature weight-optimized second-generation Sidekick Pro Straight Pull Hubs, with a faster 9° narrowest deadband setting, providing quicker engagement for long climbs and rapid accelerations.

Tool-free deadband adjustment between 9°/13°/18° allows the deadband to be widened, increasing anti-kickback effects for more technical terrain.

Sidekick effectively eliminates pedal kickback at its source, improving suspension performance, enhancing comfort and control, and reducing fatigue.

The low-profile Flux Pro 33 and 43 Carbon Rims, unique to Optimus wheels, have been purpose-engineered to optimize desired front and rear trail wheel characteristics.

Exceptionally light, compliant, and comfortable, Flux Pro 33 rims are ideal for front wheels, maximizing traction while reducing arm fatigue.

Rear wheels utilize tougher Flux Pro 43 rims, which blend compliance and durability without a significant weight penalty.

Near silent hub operation and less fatigue means a more immersive and confident experience in the backcountry.

The result is an exceptionally comfortable wheelset that tears up singletrack and dominates climbs, without fear of technical terrain.
