The revolutionary Twinwall® handlebar is an oversized diameter 1 1/8" (28.6mm) handlebar 

which utilises two tubes, one within the other, borrowing principles from aircraft design 

to give the best combination of lightness, strength and safety.

Since their introduction in 1998, the Twinwall has been the handlebar of choice for more 

professional race teams and has helped more riders win championships 

than any other handlebar in the world.

Please note your bike will require oversized bar mounts if you do not already have fat bars or twinwalls.
