Review on Corki Double Lock On Mountain Bike Grips for MTB and Downhill Riding by Dave Moody

The non-five star reviews here lack the specific complaint "not great. Spend more to get better" and some comments like "they won't be blocked" are just plain wrong. These pens are just great. I was blown away by how well made the aluminum locking rings are, how perfectly they fit my stock MTB handlebars (no play) and even pleasantly surprised by the good quality of the hex bolts. The grippy rubber compound is the right combination of stickiness and elasticity and feels great. I also bought another grip option they offer and I like it better for downhill or all mountain while having these installed on my XC hardtail. Then factor in that these grips are insanely cheap for their quality and you have an undeniably 5 star product. Today I'm ordering two more sets of each handle type to ensure I have more when needed.
