The Wolf Tooth ALT MK0 brings the proven XC race platform to another level. MK0 ALT XC Clipless Pedals are built with the finest components available for strength, durability, and weight reduction. Inside you'll find DLC-coated machined titanium axles, three low-friction cartridge bearings, and an IGUS bushing with a custom radial seal that protects internal components from trail debris. Simply put: these pedals perform at the highest level in any conditions. Ti hardware and aggressive machining drops 49g of weight and at 246g per pair, they are built for extreme performance in World Cup XC and gravel racing. ALT MK0 are substantially lighter, thinner, and offer better power transfer than any other SPD compatible pedal.
MK0 ALT XC Clipless Pedals feature an extra large platform area that maximises pedal to shoe contact, creating unprecedented power transfer when compared to other XC pedals. Most SPD-compatible XC pedals only contact the shoe at the cleat and cage interface, which can feel like pedaling on a golf ball.
For MK0, Wolf Tooth doubled down on the ALT pedal design, leveraging even more aerospace materials, each optimised for weight savings, durability, and speed. Titanium axles and hardware, stainless steel bindings, and finely machined 6061 aluminum pedal bodies converge in a special blend of high performance witchcraft.
MK0 ALT XC Clipless Pedals feature an SPD-compatible stainless steel binding that works with your existing SPD cleats, and are optimised for Wolf Tooth MK0 stainless steel cleats, included in the box. The engagement experience is improved, so you can swiftly clip in at the start of the race, stay clipped in when it matters most, and unclip as quickly as needed.
Like all Wolf Tooth pedals, adjusting the Q factor (pedal stance width) moves the pedal toward or away from the center of the bike. MK0 ALT XC Clipless Pedals feature patent-pending Q factor adjustment options of 51, 55, and 59mm to fine-tune your fit, and ship set at 55mm. Adjusting Q factor is simple enough to do at home. (See details below)
After two years of development, Wolf Tooth launch a new era of clipless performance with the CTRL, ALT and DEL pedals. Each is purpose-built for a different style of riding, yet all share Wolf Tooth’s precision machining, class-leading lightness and a larger platform area, for unmatched power transfer and control, something you won’t find in standard SPD-compatible pedals.
Unlike most clipless pedals that only contact the shoe through the cleat, Wolf Tooth’s design maximises shoe contact across the entire platform. The result: increased power, confident control and consistent performance on every ride.
In order to deliver a new benchmark - one that until now, has remained largely unchanged for 30 years - Wolf Tooth wanted to nail every aspect of its clipless pedals and focused on eight areas that really matter.
CONNECTION
The CTRL, ALT and DEL pedal bodies have all been designed for maximum pedal and shoe contact. Across the range, this connection removes any sensation of ‘standing on a golf ball’ to increase power transfer and improve foot stability, for enviable control on the trails. Each pedal has been dialled in specifically for its defined discipline and the range truly dwarfs the competition.
ADJUSTABLE Q-FACTOR
This is becoming more and more relevant, as riders switch from road, gravel and MTB machines. Road bikes typically use a 145-150mm Q factor, whilst gravel-wide setups can be up to 155mm and MTB can be as wide as 170mm. Aligning all your bikes closely will mean harnessing greater pedalling efficiencies. Riders can set the Q factor on the Wolf Tooth clipless pedal range, as standard, to 51, 55 or 59mm with just two hex keys. Additional 2mm shim kits are also available, to really dial in the Q factor – a proper game-changer for bike fit.
CLEAT DESIGN AND ENGAGEMENT
Wolf Tooth set out to reboot clipless pedals and realised the opportunity was there not to redesign the cleat. With countless cleat designs on the market, SPD offers compactness and reliability, plus it is already adopted by a vast majority of riders. The full range of pedals, then, is compatible with SPD cleats.
Wolf Tooth also meticulously designed its own cleat with multiple points of engagement, so that you can stamp into the pedal as well as clipping in with the more common, toe first engagement. (This was before Shimano chose to do the same!)
GROUND AND CORNERING CLEARANCE
Extensive CNC machining of the pedal body has allowed Wolf Tooth to thin down its bodies to just 14.7mm for the DEL and 15mm for the CTRL and ALT, to minimise strikes and keep you pedalling through the rough stuff.
BEARING AND AXLE DESIGN
Leveraging the Waveform axle and bearing design gives proven reliability to the clipless pedal range. As gravity pedals, the CTRL, ALT and DEL spin on a heat treated, 17-4 PH stainless steel axle, with three custom bearings and an igus bushing, and all of their components are easily replaceable, should something wear.
MATERIALS COUNT
Hardened stainless steel bindings with stainless hardware will laugh off abuse and combat the worst of the weather, giving you a pedal that’ll last longer than any other pedal you have had before. Even better, with Wolf Tooth’s “Right to Repair”, every part is available as a spare, so that you can re-build the pedals should you need to.
MUD PERFORMANCE
The beautifully machined, 6061-T6 aluminium CNC body doesn’t just enhance the pedals’ aesthetics, the precise machining creates narrower axle housings that help to clear mud in the worst conditions.
LIGHTWEIGHT PERFORMANCE
Let’s face it, weight matters, whether you are an XC race whippet come gravel racer or riding in the bike park. The lighter the bike, the better it will feel chasing the perfect line. Every gram has been considered for these pedals, making them some of the lightest in their class, without affecting their durability and performance.
