MUNROE SG

New for 2022, the Munroe SG is an affordable dropbar alternative to our popular Munroe AL that even comes in our new black colourway. The offroad-influenced geometry provides fast handling over parkside shortcuts for those wanting to navigate the city with a little more speed. The aluminium frame and fork are solid and compliant, benefiting from Bombtrack’s signature fork, fender and cage mounting points. Tubeless-ready WTB tyres built on 650B wheels can handle the rough with the smooth, meaning if you want to take the bike off-road on the weekend, you can. A clutched Microshift Advent 9-speed derailleur holds everything steady, rounded off with Tektro Mira disc brakes for stopping power.

Easy to ride and keep rolling, its wide handlebar provides plenty of leverage.

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.
