I got these from BTD. Upgraded my hybrid bike that uses a lot of mountain bike parts. This grip had been a great upgrade. Comfortable mushroom style grip that helps reduce fatigue while being sturdy(super grippy) and comfortable. Definitely worth my money.
I use these grips on my 26 inch wheel Independent Fabrication Steel Deluxe mountain bike. I use this bike for errands, some commutes to work, or as a really efficient cruisertown bike. I like the profile of the grips, but I don't like the mushiness of the mushroom texture.
Replaced Ergon Enduro grips with the Magic Mushroom Grips, and numbness in hands while mountain biking has subsidedimproved, but still have some numbing problems. This would of course vary from person to person. I would recommend the Fabric grips for a improvement but not a total cure for numbing of hands. Also, the Fabric grips are longer than the Ergon grips resulting in a narrower effective handle bar width and the bars feel a little smaller with the longer grip length.
