The Carbon 710mm Loop H-Bar weighs only 275g (this is 241g less than the (516g) aluminum version). It passes the same strict EN/EU mountain bike standards as the aluminum and titanium bars. It is identical to our existing Loop H-bars — all the same natural hand positions, control and comfort, but 47% lighter!! The cross bar on the Loop H-Bar sweeps forward to allow the levers to go behind the cross bar instead of in front. This gives longer uninterrupted hand positions and will allow trigger and grip/twist shifters to fit on the rearward extensions (unlike the original H-bar and the Cut H-bar). The continuous front loop of the bar enhances stiffness and is good for additional aero hand positions and mounting lights, GPS devices etc. This bar provides comfort and power with an impressive weight. With the levers in the optimum position the rider is superbly placed for fast riding while still enjoying all the hand positions available. The rearward extensions allow extra leverage and a wider hand position - be it for comfort or power. All H-bars are for a 31.8 stem and the cross tube is now tapered and butted with a 31.8 mm clamp area. The grip tubes on the aluminum version are also butted for strength and weight savings.
