Question: Sold as pair or single grip?
Document: These grips made riding a lot more enjoyable. I had to slightly modify them (cut an inch off the grip length) to fit my handle bars because of how large my grip shifts are. Once i modified them they slipped on easy and tightened up fast.
This is the first review I've ever taken the time to actually write. Incredible product. Extremely well crafted and very durable. Once installed, they are amazingly tight and strong. Well done! 5 star recomm.
They add so many more hand positions. The flat part where your palm rests is AWESOME. And the ability to adjust the bar ends to any angle that is comfortable is really nice.
The listing doesn't mention it, but these are small.And I received the wrong set. I ordered GC3's but got GP3's.In spite of all that, I am required to pay for return shipping.Apparently that's all i'm allowed to say.Read between the lines.
It's just great for riding uphill while standing up. It relieves much if you are on the long run. I'm very happy with it's sturdiness and comfort, highly recommended.
I can't really give a full long term or long ride review on these yet. But I have taken 3 or 4 twenty mile rides and LOVE them so far. I bought these for a mountain bike that I'm setting up for touring. In the past before I could afford a road bike I put over 9,000 miles on a mountain bike (mostly ridden on the street with semi slick tires). All I can say is I WISH I WOULD HAVE HAD THESE GRIPS!!!
Answer: no
