ESI's ergonomic Fit Grips are designed for a completely natural hand position on your handlebar. The new designs balance the pressure that your hands exert onto the handlebars, increasing bar control significantly.
Fit XC and CR grips have three distinct areas:
INNER - This area is the perfect step up for your hands to rest against for maximum bar control in turns.
MIDDLE - This area is perfect for extra torque and powering while climbing.
OUTER - This thickest area is for better hand comfort, especially while descending.
Each area of the Fit Grip flows into each other naturally creating the perfect hand placement. Your hands instantly feel comfort when they grasp their unique shape, as if they were exclusively molded for you.
The difference between Fit XC and Fit CR:
XC stands for Extra Chunky, Chunky Mix
CR stands for Chunky, Racer's Mix
The Fit XC is the larger version and the Fit CR is the small version. So for current ESI grip users:
If you are currently running Racer's grips go for the CR
If you are running Extra Chunky go for the XC
If you are running Chunky you can go either way
