Oxbridge Geared

As easy on the eye as it is on the road.

"...A slender frame, it’s ready for the commute or to take on longer jaunts around the countryside come the weekend."

Introducing the Oxbridge Geared

Classic styling paired with the best modern manners. Based around a simple steel frame, the Oxbridge Geared will be as current in a decade as it is today. With robust downtube shifters, its easy to maintain single-chainring 9-speed drivetrain is complemented by a wide cassette to ease you up the hills. Contemporary features like dual pivot calliper brakes and wide 28C tyres also provide the best of modern technology. Long-running sealed hubs and a deep metallic paint job round off a road bike that’s as versatile as it is timeless.

    * 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.
