Carbon handlebars
When it comes to carbon bikes, greed flashes in the eyes of many bikers. But carbon handlebars also make some people's foreheads sweat. Our laboratory test reveals whether you can also trust the black precious material when it comes to the tricky component.

Bike tester Martin Peukert's mobile phone rings again. On the other end, the "VR-3" handlebar test machine answers with a piercing beep. A test handlebar is broken - that much is certain. No time to lose now. The breakage must be checked, a new test piece clamped in and the machine restarted. Martin speeds off. Time is of the essence. Because a total of 60 Edellenker run through the test cycle on the testing machine, each one bent, compressed and pulled for eight hours.

15 models from eleven different manufacturers were put to the test. We tested four of each handlebar. This is a world first. Never before has such an extensive sample been taken. The result is outstanding. Nine models scored full marks. If you compare this result with past tests, carbon is the first choice as a handlebar material.


You can find these models in the test:
Bontrager Race X Lite, Control Tech Crossbow, Easton Monkeylite XC, FSA K-Force Riser, FSA K-Force Flat, Race Face Next XC (31.8), Race Face Next XC (25.4), Ritchey WCS Carbon Riser, Ritchey WCS Carbon Flat, Specialised Carbon XC Low Bar, Syncros Factory Carbon, Syntace Duraflite Carbon, Syntace Lowrider Carbon

Supplement from BIKE 1/2007:

The message from the handlebar test (BIKE 12/06) was clear: on the whole, carbon handlebars are more stable than their aluminium competitors. In the test, 75 percent of the handlebars withstood the tough demands, compared to only 30 percent in the aluminium handlebar test in BIKE 10/02. Nevertheless, a total of six test specimens from different manufacturers collapsed on the handlebar testing machine. Handlebars are considered safe if they can withstand a constant 80,000 load changes. However, some manufacturers only managed this with three out of four handlebars. The reason: series variation. In the production of hand-wound carbon handlebars, errors can occasionally creep in - despite the strictest controls. Therefore, as with all lightweight components: After a serious fall, you should replace the handlebars and stem to be on the safe side. The manufacturers reacted after the test:
