The rubber grips were hard to install but my husband says the end caps alone are worth it; Looks great on his ReAspire mountain e-bike.My kid got a used bike for $20, bought these to replace the stock grips. Quick delivery and nice textured grip. The tabs for the end caps are plastic and broke upon installation, other than that. Recommend.My old grips were falling apart. I followed the instructions and used soap and water to help install the new grips. Even with the soap and water, it still took a lot of grip strength to install them. Once installed, they worked great. They are really comfortable; it makes biking much more comfortable having new grips.My one complaint is the design of the end caps. I specifically ordered the gray variety because I wanted to get a non-descript cap for the end. Instead the cap has the same design as mud flaps on a truck. I would have gotten any other color if that meant that I could get a different variety of the end cap. I wish there either was a way to select the end cap design or at least know which end caps come with which color.I'm so used to lock on grips that it was a flashback to put these on a bike. I used hairspray in the approved old skool style, and they went on easily. They're a nice comfy middle ground, not super slim but also not huge oury-type grips. The end caps are plastic with a thin aluminium cap glued on. They might be a little more durable than plain plastic, but definitely not as damage resistant as all-metal end caps. For the price they are fine, but don't expect anything too deluxe.My one beef with these is that the grey portions of the grips peeled right off, they're just thin rubber bands held in place by nothing, apparently just for looks. I peeled them off and threw them away before they could cause trouble on the trail. Other than that, they are fine basic grips.
