The performance features of the Speedplay Zero Pedal System read like a pro racer's wish list. No other pedal system comes close to offering the superior adjustability or cutting-edge performance features of the Zero. DUAL-SIDED ENTRY: The symmetrical double-sided pedal self-locates just by stepping down into the cleat whether the pedal is right side up, upside down or anywhere else in its rotation. No kicking, no fumbling, no looking; just step down and go.YOUR CHOICE OF MICRO-ADJUSTABLE FLOAT OR A FIXED POSITION: The Zero allows rotational float to be precisely micro-adjusted to the exact range needed or set in a fixed-position anywhere within the 15-degree adjustment range.ALL THREE FOOT-AXIS ADJUSTMENTS CAN BE SET INDEPENDENTLY OF ONE ANOTHER: No other pedal system offers the precise adjustment or convenience of independently adjustable fore-aft, side-to-side, and rotational foot positions. Unlike the inexact set-up of traditional cleats, each of the three critical foot-axis adjustments of Zero cleats can be set or changed without affecting the position of the other two adjustments. This feature also eliminates guesswork and misalignment when replacing cleats.THE LOWEST STACK HEIGHT: The Zero cleat positions your foot closer to the top of the spindle for improved power transfer.11.5 mm stack height for 3-hole mounting8.5 mm stack height for 4-hole mountingUNBEATABLE CORNERING CLEARANCE: The thin pedal profile of the Zero pedal lets you power through corners where your rivals coast.Titanium - 39 degreesPHENOMENAL LIGHT WEIGHT:Titanium pedal each - 82gZero cleats per pair - 70g/118g*LARGE, STABLE PEDALING PLATFORM: The Zero Pedal System provides the same solid connection as conventional single-sided pedals, but with Speedplay's unique, inverted design the cleat provides the platform once the cleat is engaged.QUALITY WITHOUT COMPROMISE: Zero pedals use precision cartridge and needle bearings - three of them instead of two found in most other pedals - which allows the Zero to be thinner for a lower stack height, better cornering clearance, and reduced aerodynamic drag. Like all Speedplay Pedal Systems, the locking edges of Zero pedals and cleats are metal-on-metal for durability and safety, unlike our competitors who use engagement edges made of plastic.FITS MORE SHOES: The Zero cleat fits any shoe with a 3-hole or 4-hole mount.EASY MAINTENANCE: A built-in grease port for easy bearing lubrication.TRUE LOCKING MECHANISM: The Zero's locking mechanism does not rely on spring tension for security, so entering and exiting Zero pedals is easy, but unintended release is virtually impossible.
