MUNROE AL
Available in either our latest matt black or the existing matt pewter finish, we built our affordable Munroe AL based on a light, responsive aluminium frame, with a simple single-chainring drivetrain and competent 650B tyres. Its simplicity keeps maintenance to a minimum, while flat bars ensure comfort in all conditions. Reliable disc brakes respond well even in the rain. With Bombtrack’s signature range of multiple luggage configurations, the constant stop-start of riding through the city has never been this fun.
An investment in healthier urban transport.

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.
