Sender CFR Underdog

A gravity-first downhill bike with a durable build, adjustable stance, and suspension support for demanding courses. Final fit depends on reach, stack, wheelbase, rider preference, and terrain.

Smaller sizes feel easier to move beneath the rider; larger sizes add room and stability. Use published measurements as a starting point, then confirm with a fitting conversation.

Delivery cost, timing, assembly requirements, and return eligibility are confirmed during checkout. Review the current policy before payment.
