The Good: Tacky, feel great, just the right size, they never move on the bars - and they look great too (with loads of color options for the lockrings + the custom stuff that is also available).
The Bad: There is nothing bad per se. They do wear out, I typically go through maybe 3-4 pairs per year (riding 2-3 times per week). Note that they still work every bit as well even when they're falling apart, I usually change them out just for that new feeling (and look).Overall Review: It's one of the few constant parts on my bikes over the years, I just never see the need to even try anything else. As good as it gets!
