MUNROE SG

 The drop bar version of our lightweight Munroe AL, the SG, is the perfect urban adventure bike. The triple butted aluminium frame responds easily to input from the wide handlebar and delivers a smooth ride on 45 mm balloon tyres. Propulsion is leg powered via Microshift’s Advent 9 speed drivetrain, with an 11 – 46T cassette and a clutch rear derailleur for when you wander off the beaten track. The frame and fork have our signature collection of mounts to carry your work clothes or your overnight camping kit or both. The fork has internal dynamo routing for a front light and so there is no need to be home early.

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.
