Mondraker Summum R Mullet Bike Built to race the clock. The Mondraker Summum R Mullet is a full-on downhill race machine built for riders who want to go fast when the trail points straight down. The 6061 alloy Stealth Evo frame runs 200mm of Zero Suspension travel and Mondraker's Forward Geometry for a longer, slacker setup that inspires confidence at speed. A Fox 40 Performance fork with 203mm of travel up front and a Fox DHX2 Performance Elite rear shock handle whatever the mountain throws at it. The mullet wheel setup drops a 27. 5" wheel out back for added maneuverability and pop, while SRAM DB8 four-piston brakes with 220mm front and 203mm rear rotors ensure you can actually scrub speed when you need to.
