Speedplay Road Bike Clipless Zero stainless steel pedalset black 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. 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. 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.
