Wolf Tooth SHIFT Gravity Clipless Pedals are designed for maximum support and unparalleled confidence for downhill, enduro, and aggressive trail riding with flawless clip-in/out performance. No other SPD-compatible pedals have a platform as large as SHIFT (1201 mm²). This platform contacts and locks in your shoe for confidence in extreme terrain at high speed. SHIFT Gravity Clipless Pedals are simultaneously lighter (410 g) and thinner (15 mm) than all other gravity mountain bike pedals with an exceptionally low stack height. The thin profile means better cornering clearance and a lower center of gravity on the bike, while the open center between the binding cages increases mud shedding ability. SHIFT Gravity Clipless Pedals have adjustable Q factor in 4 mm increments. Inside the pedal is a stainless steel axle, three bearings, and two spacers. Spacers and bearings can be rearranged for Q factors of 51, 55, or 59 mm. This is simple enough for anyone to do at home. A spacer kit including four 2 mm spacers is available for purchase to further fine tune Q factor adjustment. Like most Wolf Tooth components and accessories, replacement parts and service guides are available via Wolf Tooth Right to Repair. - Thinner than the competition at 15 mm (compared to the Shimano Saint at 18.8 mm and the Hope TC at 18.2 mm) - Lighter than the competition at 410 g (compared to Shimano Saint at 546 g and Hope Trail at 438 g) - Bigger platform area than the competition at 1201 mm² (compared to Shimano XTR 9220 at 883 mm² and Hope Trail at 645 mm²) - Adjustable Q factor range of 51, 55, and 59 mm (additional 53 and 57 mm options available as 2 mm spacers sold separately with spacer kit).
