Description

The major upgrade that hadn't occurred to you.

The GR2 BioKork Grip is just like the GP1 BioKork except that it is terminated by a three finger composite bar end. The bar end offers up an additional hand position and more leverage for climbing out of the saddle. Instead of solid rubber, this grip uses natural cork, harvested from certified sustainable trees in Portugal for 40% of the cover. In addition, it also uses grass fiber for 40% of the grip core and vegetable oils instead of mineral oil in the gel palm insert. The benefits of cork's natural low density are a lightweight and comfortable grip

Ergon's patented wing-shaped grips support your hand and wrist in a way that relieves pressure on the Median and Ulnar nerves -- pressure that causes numbness, tingling, or pain. The shape of the GR2 BioKork Grip is a replica of Ergon's bestselling GP1 grip, and it's a great starting point for an exploration of Ergon's wares. By comparison, the GP1 shape is a bit more forgiving than the race-oriented GX1. So those looking for the most comfort, look no further. Each grip is held in place by a built-in clamp assembly on the bar end and set by a 4mm hex key. The angles of the grips and the bar ends can be adjusted separately, and when both are oriented to your preference, the clamp hardware should not be tightened in excess of 5nm.

The Ergon GR2 BioKork Grip comes in two sizes -- Small and Large. The size does not refer to the length but the thickness of the grip. The people at Ergon tell us that macho types assume they should have large unless otherwise indicated, so consider this a warning. Ergon has found that most people, except those who have huge mitts, go with the small. 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 GR2 BioKork Grips are 54mm at their widest point (measured front to back) and are 132mm long. The left and right grips are mirror images of each other. They come with end plugs and mounting 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.

  • Ergonomic ‘wing’ design relieves fatigue-causing stress on pressure points in the palm
  • Built-in ergonomically-shaped climbing bars give you more power on the climb with minimal weight addition
  • Two sizes for different hand sizes
  • Bar end doubles as the clamp and allows separate angle adjustments for grip and bar end
  • This grip is not suitable for use with carbon handlebars
