Which one should I get? I'm a new rider and just bought a Trek 7.7 FX. My hands do hurt after riding for a bit and found out these Ergon Grips will do the trick but don't know which one to get? What do you guys recommend?
I had GC3s on my bike before converting to drop bars and felt more hand pain than with my old grips. If you think your hands are remotely large be sure to get the large size. I have gigantic hands and didn't do that. The grips are on my wife's bike now and she loves them.
What do you mean by "flipped the stem"? Can I see pics of your bike?
It means you take the headset cap off, loosen the stem bolts, and flip the stem upside down. This will result in the stem being much flatter, which helps for some. If you're going to flip your stem don't forget to do remove the handlebars first (obviously).
GP-1, so you can put anything else on, or in, the bar. Some of those others will limit what you can add later - like bar ends, or mirrors, or mini drops, or whatever else you dream up. The GP-1s will let you do anything......
