Avenger Bikes

Avenger engineers aerodynamic carbon road bikes for competitive cyclists. The Shuttle and Shuttle SL platforms deliver wind-tunnel-tested performance with fully internal routing, flat-mount disc brakes, and thru-axle dropouts — available as complete builds with Shimano or SRAM groupsets, or as standalone framesets for custom builds.

Every Avenger bike sold through Underdogs Cycling is available in multiple sizes and colourways with your choice of bar width, stem length, crankarm, chainring, and cassette configuration. Pair with carbon wheelsets and a BERK saddle for a complete race setup.

Because Underdogs Cycling sources Avenger factory-direct, you get a wind-tunnel-developed aero race bike at a price traditional retail can't match — with a multi-year frame warranty and tracked worldwide delivery, shipped largely pre-assembled for a straightforward final setup. Unsure which size, colourway or component spec fits you best? Send us your height, inseam and riding goals and we'll help you dial in the right Shuttle or Shuttle SL build.
