CALE E

A Shimano EP8 mid-engine and aluminium frame blended with Shimano SLX and Deore XT parts, the Cale E is our first bike with a mullet setup. Running a 29’’ x 2.4’’ tire up front and a 27.5’’ x 2.6’’ tire at the rear, it combines superb rollover characteristics with playful manners.

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.
