With victories in races such as the Tour de France, Paris Roubaix, Giro d Italia, the Tour of California, and the World Time Trial Championships (just to name a few), Speedplay’s Zero pedal systems have more professional road wins than any other pedals on the planet. While many of the clipless pedal systems on the market today are based on ski-binding technology, Speedplay has designed their unique Zero system from the ground up specifically for cycling. This Nanogram Zero version features the same DNA as all of their Zero pedal systems, however the engineers at Speedplay have completely “hot-rodded” this version of the Zero pedal system. A complete re-engineering of the pedal and cleat using various exotic materials has resulted in an approximate 20% weight reduction over the extremely lightweight Zero Titanium (a total savings of 63.5 grams; 34 grams for the pedals plus 29.5 grams for the cleats).
While this is the lightest Zero pedal/cleat system available, all versions (Titanium, Stainless or Pavé) share the same patented design characteristics. To begin with, the system features a unique and ingeniously simple design that places the locking mechanism on the cleat, leaving only one moving part on the pedal itself - the spindle. This design feature saves significant weight over many other clipless designs, furthermore pedal weight is rotational, making the savings even more important. In addition, this spindle rotates on three bearings instead of the more common two bearing design seen in many pedals. The additional bearing adds more support to the spindle while also allowing Speedplay to design the Zero pedals to be thinner, allowing better cornering clearance and reduced aerodynamic drag. The lower pedal stack height (11.5 mm stack height for 3-hole mounting, 8.5 mm stack height for 4-hole mounting) also improves power transfer by positioning the foot closer to the top of the spindle. The pedal body is a symmetrical, double-sided design that, unlike many other road pedals, allow entry from either side. Beyond allowing double-sided entry, no matter where in their rotation the pedals are oriented, they self-locate onto the cleats when stepped on, reducing fumbling and errors while clipping in. While the Nanogram bearing system and pedal body design offer the same functionality of the other Zero systems, exotic materials have been utilized to gain significant weight savings as well as performance benefits. Specifically, the Nanogram pedal body itself is made from carbon fiber reinforced thermoplastic, one of the cartridge spindle bearings is upgraded to a cermaic bearing, and the fasteners and bowties are now made from alloy and titanium. Additionally, the Nanogram features the same lightweight titanium spindle as the Zero Titanium, a feature reserved for only the two lightest Zero system pedals.
While the Zero pedal body itself is compact, with Speedplay’s unique inverted design, the cleat (once engaged) provides a large and stable pedaling platform on par with traditional one-sided road pedals. The locking mechanism of the Zero system does not rely on spring tension to secure engagement, making entering and exiting easier while simultaneously making accidental release nearly impossible. To further secure pedal to cleat engagement, Speedplay has designed the locking edges of pedals and cleats to be metal-on-metal, increasing both durability and safety. While maintaining all of the functional qualities of the Zero cleat system, the Nanogram Zero cleats (included) shave 29.5 grams per pair over the standard Zero cleats. This weight savings is achieved through the use of carbon fiber reinforced thermoplastic along with alloy fasteners in the cleat body construction.
Another benefit of the Speedplay Zero system is the high level of adjustability. Within the 15 degrees of adjustment range, float can be micro-adjusted to allow the precise setting of float range. Beyond the ability to micro-adjust the float range, these cleats can also be set to have a fixed-position with zero float. The cleats also allow independent adjustment of all three foot-axis; each of the three critical adjustments (fore-aft, side-to-side, and rotational) can be performed individually and without affecting the others. Not only does this independent adjustment make initial set-up easier, it also eliminates guesswork and misalignment errors when replacing cleats. Speedplay cleats are compatible with both 3-hole and 4-hole mounts, making them usable with a wider variety of cycling shoes. To keep everything working smoothly, the pedals feature a built-in grease port for easy bearing lubrication.
As the system weight indicates, the Nanogram Zero’s have been designed and engineered as a race-day/event pedal system. It will also serve well for those who just simply want one of the lightest pedal systems available, however service/replacement intervals will be more frequent under daily/training use. Also of note: Nanogram Zero pedals are not compatible with Speedplay Ultra Light Action and X-Series cleats and Nanogram Zero cleats are not compatible with Ultra Light Action and X-Series pedals.
