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.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore Bombtrack cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local Bombtrack dealer or a professional bike fitter and have them determine the needed size.
