2014 Tune carbon fiber mountain bike handlebars

German lightweight component manufacturer Tune has just added two new carbon fiber mountain bike handlebars to their lineup.

Both are 750mm wide with 31.8mm clamp sections. The riser has a 15mm rise, 5º backsweep and 3º upsweep. Claimed weight is 125g. The flat bar has a 6.5º backsweep and comes in a claimed 115g. Both pass EN and EFBE testing and come with a 110kg (242lb) rider weight limit. While it seems obvious, the guys at Fair Wheel Bikes (US importers for Tune) included this warning: Not for DH riding. And in true Euro fashion, both can be cut down to a skinny 650mm width.

  1. The handlebar is the one component I wouldn’t want to be ultra-light. I could easily get by with an extra 100g for the peace of mind of not having to think about getting my arms filleted with carbon splinters.

  2. That is absolutely, positively the LAST place to save 100 grams…

    …and I’m not worried about carbon splinters either. I’m more worried about an unplanned “dismount” forward and sideways, head first.

    My C-spine says no thanks. I’ll stick to your hubs, or pretty much anything else, really.

  3. You gotta remember there are guys like me who weigh 68kg/149lbs who would like their bar to flex a little for comfort. I’ve got a Renthal fatbar light carbon bar in 740mm and it weighs 180gm and has no noticeable flex and im sure that it because of me not being a heavy guy even though i am a more aggressive rider.

  4. 650 skinny? before yesterday we ran 560mm -barends with, with no issues at all.

    What about barends compatibility? for those of us who do not get payed to do those embarrasingly artificial XCO circuits, with fake steep rock gardens and all that stuff, we use barends. Here in europe I mean. In US people don’t know what is a +90Km mtb ride…

  5. maLoL, Tune is a German company, so maybe look at your own continent’s component creation before calling out a country of 300 million people for their supposed inferior riding skills.

  6. kyle it’s not about riding skills, but rather different riding style. I’m running a 710 mm wide bar, but all of my friends still have 580-600 mm flat bars. For them and for most of the people in Europe 650 is wide.
    Simply for natural XC trails you don’t need that much control and narrower bar is more comfortable on long +80km rides.
