I got the CHINA sourced ones off Fleabay and the effing things shredded while trying to push on the first grip. Yes, I'm admittedly a hack mechanic but I've been a bike rider and motorcyclist for 20 some years now and I've swapped out grips countless times. The bar end "plug" on the china grips are actually faux plugs, and simply glommed on the end of the too soft rubber grip itself. The act of pushing the grip on and trying to see if the thing was bottomed out on the end of my bars riped the plug right off the grip, with almost no effort. I'm a 170lb guy not a hulk. Very dissappointing despite the cheap price. Well, cheap and wrong is always disappointing. BUYER BEWARE
