Munroe SG
"An investment in healthier urban transport."
Bombtrack 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.
