Ergon GP1 vs. GC2
 

I know Ergon is the ergo grip of choice here and I was looking at the GP1 standard grip and the GC2 with the smallish horns. I currently just have flatbars so the GC2/3 horns intrigue me as I'm not quite sure what I'd do with them. I gather from youtube they can be useful for climbing but it seems your arms would be quite wide to grip the horns long-term. I think the GP1 would do the bulk of the job as far as vibration absorption and ergo. But it's not much more to get the GC2.

Anyone care to inform me if the horns make much of a difference and how/why?

Also, an aside is the hand-size thing... depending here you start from wrist to finger i'm like an 8 but my spade-like hands are maybe 9.5. I guess I should get a large but I would prefer to try them first to verify a large isn't too much to grip possibly causing fatigue. Any advice?

I bought the GC2 for my mountain bike. I had bar ends on it before but I decided that the GC2 with it's built-in bar end had a cleaner look. It allows you to position your hands a little differently on the end, turning your fingers to the outside, if you want a change of grip. I can only wrap two fingers around the bar end for climbing or accelerating so they aren't much for that, but better than nothing. They are also enough to hold my headlight off of the ground when I turn the bike upside down to work on something. :-) I like them, but I have some trekking bars coming that I want to play with, so I'll probably get a pair of GP1s to go on that. I haven't decided yet.

As for size, I bought mine in a lbs so I could grab them and see what I liked. I have long fingers so ended up with the larger size.

I have the GC2 Large grips on my commuter. Love them. I also bought them at my LBS and was able to hold both the large and small sizes. I don't have the biggest hands and still find the large version comfortable.

As for the bar-ends, that version was only $2 more, so I said, "Why not?" While I don't find them that advantageous for climbing, accelerating, etc., they are nice for that extra hand position when you need to change it up for a bit.

Thanks for the replies, was useful. In the end, I may regret this, I went generic.

For the same cost as the gp1s I got some german knock-offs and a cruiser bar.

Those should be fine, as long as you like the bars.

I have a set of knock-offs similar to the ones pictured above. They were indeed much cheaper than Ergons (~$15), but I found that the rubber was much more pliable, and therefore offered less support under the meat of my palms. Also, the inner and outer clamps used different sized bolts! :twitchy:

I see the OP already made a choice, but I'll post this for any others who may be looking into getting these grips.

I have both the GP1 and the GC2 on different bikes and find them to be the most comfortable grips ever. On the bike with the GC2's I almost never use the bar ends... I find the normal position perfect for everything. My hands are medium sized and I prefer the extra size and support of the large grips. So if you think you may be in between sizes, I'd say go with the large.
