Question: Which part of the grips faces up?  The black or grey?  I'm figuring black but these things have absolutely no directions with the item.
Document: First off, I love these grips. They are very comfortable and are a game changer.Two things to pay attention to when installing them:1. Which way they go, which sounds silly but will affect their comfort level. You want the thickest black part positioned so the palm of your hand rests on it.2. Reviewers have given a bunch of different suggestions for how to get these on your handle bars....soapy water, hairspray, WD40.
These things look and feel great. The end caps are really nice too. They have the Avenir logo under a clear jewel that makes it look 3d. and $7!, those cheapy Bell grips are $8 at Walmart. You really can't go wrong with these. They also look like they will hold up better than other grey and black ones that separate between the two colors.I would not recommend these to someone wanting bar ends or for grip shifters. They are very wide.
These are great grips at a good price. Easy to install with some soapy water, and they're comfortable. The only issue I have with them is that I wish they were different colors, like black on darker grey for instance.
Came in a set. Like the color and the texture. Feels soft and provides a good griping surface. Will be a great addition to my Citizen Folding Bike. Note: I'll attempt to use the full length surface of the Grips. Buy moving the hardware on the handle Bar inwards to accommodate the full use of the  Avenir Comfy Soft Grips (Black/Grey, 137mm). I see no reason of cutting the Grips. Just move the Brakes hardware inwards to accommodate the full length of the grips.
These are great and feel good on the hand. Good for long rides and short ones to. Just make sure you follow the directions. At first put on wrong, Because at time I think I'm right without reading all the material that come with it. But good for the money. Would buy again and told all my friends.
Bought this for my wife for her Trek SL WSD bike. The color matches the grey frame very well. She did not like the white grips that were there because they look dirty and there were not as curvy and easy on her hands. She thought these were &#34;gel&#34; filled and super soft. They are not.
There's a lady at our church who rides a bicycle to get around. Someone had given her the bike, and it was in need of several things to make it safe and legal. Among other things the bike needed, it had bare handlebars, making me cringe to think of her riding it that way. So I got these Soft Grips for her, and they came well packaged and in good shape.
Comfort and Positioning:-This item is described as "soft" which is simply not true. They have about as much give as cork bar-tape, or maybe a fully inflated basketball. That being said, I am a firm believer that soft/cushy grips don't help. The real strength of this kind of grip is in the "ergonomic" shape. The purpose of the wings is to keep your wrists straight, not to provide a platform for you to lay your wrists out flat.
I replaced my grips on my bike a few months ago and I'm loving these new ones. The design makes it so the heel of my hand rests comfortably.
This item seems well made but doesn't fit either of my Trek bikes and for the price it is not worth returning. :(
Answer: yes
