OXBRIDGE GEARED

The Oxbridge Geared offers that classic look complete with skinny double butted steel frame and fork, a polished quill stem, engraved flat bars and a paint job to match aluminium fenders. A Dia Compe ENE downtube shifter operates Microshift’s 9 speed rear derailleur and 11 - 34T cassette for a wide range of urban cruising gears. Polished aluminium 700C wheels running 28 mm tyres provide a fast smooth ride, kept in check via Tektro’s flat bar levers and dual pivot calliper brakes. Rack mounts on the frame and fork offer cargo options beyond looking cool at the local cafe.

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.
