Tioga recently unveiled its new ZEROaxle MT-ZERO pedal. Measuring just 7 millimeters thick at each end and 4 millimeters in the middle, the MT-ZERO can claim the title of world’s thinnest dual-concave off-road bicycle pedal.
"The breakthrough is made possible by Tioga's ZEROaxle bearing system," said Kai Cheng, Tioga's global marketing manager. "With conventional pedals, the body must be tall enough to contain the axle and bearings that are within its body. The ZEROaxle system in the MT-ZERO removes this restriction by redirecting its axle and bearing away from the body, allowing for an incredibly thin profile."
The design is centered around the ZEROaxle bolt assembly, which houses an outboard sealed cartridge bearing allowing the pedal to rotate (and eliminating the need for a traditional axle). The ZEROaxle cartridge bearing is more than twice the size of traditional pedal bearings and, according to Tioga, is capable of handling over five times the dynamic load of typical bearings.
A thin pedal profile generally allows better ground clearance, foot stability and pedaling efficiency.
Although the MT-ZERO body is extremely thin and open, Tioga claims that it isn’t flimsy or fragile. The MT-ZERO's body is made of one-piece, investment-cast from chromoly steel, and has been tested to handle a wide spectrum of off-road applications from XC to all-mountain.
The ZEROaxle pedal system is modular and designed to be virtually maintenance free. Should the bearing wear down, simply replace the ZEROaxle bolt. The same applies to the body. Replacement ZEROaxle bolt and MT-ZERO body are available individually, in left or right configurations. Its modular design will also allow users to easily switch different body designs from any current and future ZEROaxle pedals.
The pedals will be available for suggested retail price of $99, and will tip the scales at a claimed 450 grams per pair.
The MT-ZERO pedals will initially come in three different colors–black, white or silver.
