Regardless if you're new to mountain biking or a top-level rider seeking a solid pedal for dissecting technical terrain at high speeds, the Crank Brothers Stamp 3 V2 Pedals perform admirably with their size-specific design, bombproof durability, and ten adjustable pins for greater traction. Updated for 2020, the Stamp 3 V2s tip the scale at a considerable lower number than their predecessors. 6061-T6 aluminum maintains rugged durability from rock strikes and accidental bashings on the trail, while the premium bearings and seal system keep nasty grit and muck from compromising their smooth feel over time. Since they're only 16-millimeters thick, you'll find they're not as chunky as older platforms from the past, with a slightly concave design hugging your shoe, so it doesn't accidentally slip off.Updated platform pedal with durability and lower weightw 6061-T6 aluminum for rugged durability on the trailPremium bearings, seal system for smooth-spinning feel10 adjustable traction pads per side for extra gripSlightly concave design keeps feet from sliding offSmall works best for 5-10 size feetLarge is for riders with 10+ feetMaterial[body] forged 6061-T6 aluminum, [spindle] forged scm 435 chromoly steelRemovable Pins10 adjustable pins per sideSpindle Diameter9/16inPedal Wrench Type8mm allen keyDimensions[small] 3.9 x 3.9in (100 x 100mm) [large] 4.5 x 4.4in (114mm x 111mm)Claimed Weight[small] 12.4oz (351g), [large] 13.6oz (386g)Manufacturer Warranty2 year
