Ergon GA1 Review

Components Pro Reviews

These ergonomically shaped All Mountain grips are pretty darn sweet and near perfect. They are durable, comfortable, and their natural anatomic shape means decreased hand and upper body fatigue, and better athletic performance. At first glance they really don’t seem any different than other lock-on grips, but looks are deceiving, as their ergonomic design has a plethora of benefits and functions. Ergon takes part of its name from the word Ergonomics, which is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems.

GA1 and GA1 Leichtbau
The grips come in two models, the GA1 and GA1 Leichtbau, the latter being slightly lighter in weight due to a different rubber compound. Both versions come in two sizes, a small and large, with dimensions of 32mm x 139mm and 35mm x 145mm respectively. I tested only the large size in each model, and they weighed in at 147 grams (GA1 L) and 155.8 grams (GA1). The ergonomically shaped rubber grips, have four different textured areas, and use an aluminum lock-on clamp, and come in three colors, black, white and team green.

The grips on a bike are a pretty important entity, especially a mountain bike, since they are how you hold on and steer, and they comprise two out of the five points of contact with the bike (two grips, two pedals, one saddle). Most grips are simple cylindrical objects, with padding (soft, hard or multi-density), and can have texturing, lock-on’s, colors, etc. If you curl your hand, you’ll notice that your grip has a slight concave shape to itself. When grasping a normal grip with the same diameter along its length, the flat surface causes the hand to push the palm downwards, spreading it out in an unnatural position, which causes stress, weakens holding power and irritates the ulnar nerve. The GA1 uses a multi-dimensional convex shape that cradles the hand’s curve in a natural and ergonomic manner, which increases comfort, support and performance, and reduces hand fatigue. The GA1 grip and your hand form a synergistic matched pair, so less force is required for any activity.

    It would be nice if the reviewer mentioned the sizing of the grips, and what size gloves he wears.

  • jadedbee says:

    What a timely review; I was just about to get a set of these! I’m currently using ODI Ruffians and like the large diameter, so I’m guessing the large GA1s will be my size. Did you feel much of a difference between the GA1 Leichtbau and the regular GA1s? Could you say what grips they feel hard in comparison to?

  • Brian Mullin says:

    They feel hard compared to my ESI Chunky’s. I liked the GA1′s better, but the GA1L did have a nicer feel, but wore out quicker.

  • Laiheng says:

    I’ve had these grips on my XC for a year. They’re awesome grips!

  • hardmtnbiker says:

    I’ve used and loved the OURY lock on grips because of their big soft blocks. If the Ergon where as soft and not so pricey they would be a consideration.

  • wont stay in place says:

    i really like the shape of just about all of the ergon grips. but i can’t get them to stay in place on a carbon easton bar. i’ve got two pairs, on two easton bars and they both move. tried everything. finally over-tigthened one too much and snapped off the bolt head. anyone else have this problem?

  • erik says:

    I have the GE-1 which are largely the same but with a hook sticking on the inside (stem side) of the grip. I use LG or Giro gloves with little to no padding. Using these for endurance racing and everyday riding.

    I have Ritchey carbon bars and do not have movement issues maybe carbon paste on the bar under the clamp?

  • Disco says:

    Good to see this topic getting so much attention, my favorites allow for multiple hand positions but not the one finger braking that comes naturally here.

  • Laiheng says:

    I have Ritchey carbon bars too and also no movement issue detected.

  • Brian Mullin says:

    These were installed on several brands of carbon bars, and I never had an issue. You might also try a bit of Teflon tape under the clamp area to help them stick?

  • wont stay in place - II says:

    thanks, guys. i’ll try teflon tape. i’ve tried the fsa assembly paste, and that doesn’t help for very long.
