Bar ends may not be all that popular anymore, but there is definitely something to be said for having a grip that allows multiple hand positions. Ergon's GS2 Grip has a small, composite three-finger 'hook' that provides additional hand positions and control when climbing out of the saddle without being as obtrusive as full bar ends.
The grip shape of the GS2 is 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. 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 the bar end is important and worth the time to find the position that works best for you. Once you dial it in, 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.
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.
The Ergon GS2 Grip comes in both a Small and Large size. It is available in White and Black.
