HOOK EXT RIVAL AXS
This is where our classic Italian steel frame comes face to face with 21st-century American engineering. The Hook Rival AXS uses the same Columbus Cromor double-butted frame as the EXT, but adds wireless electronic 12 speed shifting from Sram. Using the 10 – 44T cassette and a direct mount 38T chainring means you’ll be even faster along the singletrack sections, plus you’ll be still able to laugh at the technical climbs. Seido’s MGV fork offers loads of mud clearance for grippy WTB 2.0’’ Ranger tyres seated on wide rims for greater support. Sram’s Rival hydraulic disc brakes with a 180 mm rotor up front will haul you back down to earth should you get a little carried away on the descents. Get the map out, plan a route with your friends, load up and head off.

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.
