"The Rival drivetrain gives this Arise model the edge, and amplifiies its multisurface spirit"
Bombtrack Arise SG Rival
The Arise SG Rival is a versatile allroad bike built for riders who demand performance, comfort, and reliability - on pavement or beyond. Its double-butted chromoly frame is paired with a classic brazed steel fork, featuring flat mount brake compatibility and thru-axle dropouts for added stiffness and precise handling. Internal routing for lighting cables keeps the setup clean and adventure-ready. Sizes XS and S roll on 650B wheels, ensuring a proper fit and consistent geometry across the range. The bike is equipped with a SRAM Rival 1x11 hydraulic groupset, offering powerful braking and smooth, reliable shifting. A clutched Rival rear derailleur paired with an 11 – 42T cassette provides a wide gear range for steep climbs and loaded rides. Tubeless ready WTB ST rims complete this capable, no-nonsense allroad machine.
