Ergon's GS2 Leichtbau Carbon Grip employs a shape that falls right in-between the classic GP and GX series, offering a shape that works to reduce pressure on your Ulnar nerves and to ease wrist strain while retaining the lightweight characteristic of the GX1. It differs from the GS1 in that it has a three finger carbon fiber bar end for additional hand positions and control when climbing out of the saddle.

We feel like this happy medium will quickly become a favorite for anyone looking to increase their hand comfort on their mountain bike. The wing shaped support is exactly where many glove makers are stitching on extra padding these days, and it provides more support for your hand. You'll perceive less pressure on your palm because of the increased surface area, and the soft kraton rubber gives just enough and allows supreme grip, even with sweat soaked gloves. You'll see a textured rubber insert on the top of the grips. Ergon uses a softer rubber compound here to help dissipate vibration and jolts on the trail.

The angle of the grip and bar end is important and worth the time to find the position that works best for you. The clamp at the end of the grip should be tightened to a maximum of 5 Nm in order to avoid handlebar damage once you find the right angle. Ergon has found that most people, except those who have huge mitts, go with the small size. The smaller diameter is lighter, a bit stiffer, and easy to grab. Those with big hands and those who spend long, long days in the saddle might want to lean towards large.

The Ergon GS2 Leichtbau Carbon Grip is available in two sizes -- Small and Large. The GS2 is 132mm wide, including the clamp assembly; and it's 54mm front to back at the wing. The set comes with bar plugs and installation instructions.

Please note: when mounting Ergon grips with integrated bar ends to carbon fiber handlebars, it is necessary to confirm that the handlebars are both rated for use with bar ends and are able to accommodate 6-8 NM of clamping force. Most carbon bars are not designed for use with bar ends, which can result in structural failure if applied.

Great grips, if you like a bar end.

  • Familiarity: I've put it through the wringer

I've been riding MTBs for more than 25 years, and while I've come around to wide bars and short stems, I still love flat bars and bar ends for climbing. These are very comfortable on the bar, and the little carbon bar ends are awesome. And they are relatively light.

Unanswered Question

Can these be mounted on carbon fiber bars?...

Can these be mounted on carbon fiber bars? What does the size refer to - hand size or handlebar diameter?
