MUNROE SG
The Munroe AL SG blends city style with off-road capability in a sleek drop-bar package. Its lightweight, triple-butted aluminium frame and wide bars offer agile control, while 45 mm balloon tyres keep your ride smooth—on pavement, gravel, or whatever comes next. Equipped with a reliable Microshift Advent 9-speed drivetrain, a wide-range 11–46T cassette, and a clutch rear derailleur, it’s ready for hills, shortcuts, and the long way home. Plenty of frame and fork mounts let you carry everything from office gear to camping essentials. And thanks to internal dynamo routing in the fork, you’re free to ride late—no rush, no curfew. The Munroe AL SG: Go your own way.

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.
