Exclusive to Brompton, the Marathon Racer is the fastest and lightest Marathon. It has good tread depth and uses the SpeedGrip compound for the best handling characteristics and lifespan. 

Raceguard Nylon fabric under the tread gives excellent puncture protection. The LiteSkin sidewall keeps the weight of the tyre down and the reflective strip improves rider visibility at night. E-25 safety endorsement - Rated for pedelecs with motor assist up to 25 km/h (15.5mph). Recommended for the Brompton Electric.
