the BEST grips are massi lock ons!!! seriously, they are soooooo good!! you can get them off ebay, vision 1 is the best, it used 2 grubscrews to hold it in place, they are hard to round off and offer really good clamping power (they dont dig into the bars either, specially designed) They dont wobble either (like odi grips do) and because they only have the lock on part on the stem side of the grip, theres no annoying clamp to irritate your hand. best grips ever!!
