KMC Chains | X11TT, 11-Speed

Faster acceleration｜Enhanced 4% Drivetrain Efficiency
Fabricated by tailored forging and heat treatment procedures has created an embossed double X-Bridge and optimal chamfering to provide smoother chain and tooth interaction and enhanced shifting performance. The hollow plates reduce weight while the overall chain construction reduces rider effort and therefore improves riding distance by 5% farther and drivetrain efficiency by 4% - go farther, faster!

Maintain Maximum Speed
The unique design of each component perfectly complements speed and efficiency through swift shifting and smooth running via chain and gear tooth interference. Energy consumption is reduced via significantly increased cohesion by 9% to effectively reach and maintain top speed with less effort of all chain components working together.

The KMC X-Series has been designed with the specific characteristics of the Shimano, SRAM and Campagnolo systems in mind and will meet the most demanding requirements. Elaborately designed and manufactured, the X-Bridge technology, thanks to precisely chamfered plates, allows smooth propulsion and perfect gear changes in all driving situations. The X-series is trusted by many top athletes in professional cycling.

• The time trial chain, which was limited to 500 pieces worldwide in 2019, has been re-produced.
• Chain specialized for time trials, triathlons, lap criteriums, etc.
• When driving for 1 hour at a pedal rotation speed of 90 rpm and 200 W, mileage increases by approximately 5% (compared with KMC)
• High durability and smooth gear changes are achieved by the X-shaped link plate.
• The outer and inner plates are made lighter to reduce weight.
• Compatible with all 11 speed systems including oval rings and 1×11.
• Missing link allows for easier chain attachment and detachment.
• Titanium nitride coating, limited NEO CHROME color.
• With missing link CL555R NEO CHROME (missing link can be reused.)
