All Mountain Bike Parts Descriptions
Grips - Grips provide shock absorption and "grip" for your hands.
They come in three sizes that I've seen. 3/4",
7/8" , and 1", but the 7/8" size or
22.2 mm. as it's also known, has become the standard.
They are made from rubber, foam, cork and some have
gel inserts. All of them are designed to absorb shock
but still give a solid grip to the bars.
