BIONIC Bigfoot Stoppers
The Bigfoot Toe Stops from BIONIC puts a priority on performance like never before. The huge 59mm footprint has superior grip & rebound with a unique cut that ensures wheels up to 66mm in diameter will never rub! The bottom is pre-angled so there is no break-in period. The 30mm stem fits all standard 5/8" threads.
The Bigfoot toe stops are available in 2 different grip compounds. Grip and X-Grip:
The Grip compound features the same material found in the Bionic Super Stopper, which grips better and lasts up to 4 times longer than the competition. The X-Grip compound is an ultra-sticky, high-rebound material designed for indoor performance. A word of caution straight from Atom: "X-GRIP stoppers are not designed to be long lasting and are not recommended for asphalt or abrasive cement."
Rubber-Hardness X-Grip: 74A (Soft)
