The KMC X11TT is a race-focused 11 speed chain designed for maximum drivetrain efficiency, in a Neo Chrome finish. KMC’s testing shows it improves drivetrain efficiency by 4%, and covered 5% more distance than the X11EL in one hour at 90RPM and 200 watts.
For time trial and triathlon cyclists, every watt counts. Fitting a faster chain is one of the simplest ways to gain free speed on race day, without changing anything else on your bike.
Built for speed
A specific alloy steel composition and efficiency-focused design help reduce the energy you need to keep the bike moving.
Extra light
Hollow outer and inner plates save weight for faster acceleration.
Excellent shifting
KMC’s XX-Bridge shape and optimal chamfering give smooth chain and tooth interaction for precise gear changes.
Holds up to big efforts
Hydraulic riveting secures the pins against heavy loads and stressed shifting, and the alloy reduces chain elongation to prolong drivetrain life.
