Full-sized and full speed ahead. The Pro XL is the biggest of the Race Lite series with a 21" top tube to fit the taller set. The 6000 series aluminum frame is low-profile with stable geometry to keep it tracking straight at the highest speeds. Chromoly forks and 8" rise bars make for a solid front end, able to handle even the harshest landings. Sealed bearings all around, a Promax disc brake and fast/grippy Kenda Konversion tires put the power to the track.
