Question: Do these grips come with the end caps or end plugs (with the screw in the end)? Also, why is this a bonus pack; does it come with 2 pair?
Document: these are almost as squishy as esi chunky's, they have a bigger diameter so they feel better vs stock grips. lost the end caps after 2 rides, they should find a way to contain the end cap with the clamps.
I purchased these grips for my recent purchase of a used Haro Shift R3. The bikes grips were in terrible shape, and the end caps were also beat to bits. I bought these in hopes of a meaty, sturdy, tough, lock-on style grip, and i got just that. Installation took about 5minutes, and was extremely easy. The lock on feature is at both ends of the grip, meaning they are firmly stuck in place, with no adhesive sprays onto the bars being necessary.
I was looking for slightly larger diameter grips, for comfort, and these are really nice. Excellent quality materials, looks good, and the end caps have so far stayed firmly on. Couldn't ask for anything better.
Easy to install and especially like the end caps. They are soft but not too cushy. I am happy with them.
I am not an very experienced rider but I felt these were a huge improvement over the heavily used  and very uncomfortable stock grips on my craigslist-used NEXT bike. I chose to mount the bar ends after these and the shifters and brakes before, so I have no experience with the end caps coming out or not.Overall I got what I wanted from these grips: Something better and more comfortable than I had, and they have been that.
I swear by lock ring grips nowadays. They are so much easier to deal with when changing or adjusting other components on your handlebars versus having to force off friction fit grips. Plus, the never ever slip or twist.I subtract one star on these because of the end caps. The are hard rather than the soft material I have had on other brands. Trouble is that the hard material gets no friction when leaning against a wall (a position my bike is often in).
another you get what you pay for, kinda. these work well and feel great. your hands wont be slipping of of these. the end caps were plastic. i would have still bought these even knowing that. thought you should know.
My old stock grips were constantly twisting and shifting while riding. These grips lock firmly in place with a screw and will not move at all.
If you've never had a pair of lock grips... you should treat yourself.They don't slip or slide and offer a decent amount of cushion from bumps/vibrations.
Work as advertised. They were quick and easy to install. Let's see how long the grips actually last. Will post again on 2nd pair.
Answer: no
