Both bar ends snapped while torquing them to the bars. This wasn't a case of overly aggressive torquing; this was merely applying just enough torque to keep them from slipping under nominal hand gripping forces. These are made completely of plastic. Had they used a metal sleeve insert for the clamping mechanism, I believe this would have mitigated the observed structural failures, while allowing enough torque to be applied for secure operation. I can't imagine anyone being able to successfully install use these in light of this poor design. I hate to sound like a product basher, but after my experience I felt compelled to submit this review to alert other potential consumers as this could be a serious safety issue. If one were to get these mounted successfully, I would imagine any significant application of riding force may very well trigger an untimely and unpredictable structural failure, which would result in a severely negative, if not catastrophic, impact on bike control. I would further imagine this failure potential would increase dramatically in colder weather where the plastic would become even more brittle.

Great bar ends but you really need to not over tighten them when you put them on. I have broken two due to over tighening but the current ones have been perfect for over a year.

simple, durable, comfortable and light. also serve nicely to fend trees off the knuckles a little.

Hate real barends, but needed a little position change for big rides. these totally serve the purpose.

I kinda like that they can move a bit. I wish they had some kind of bar end cap to retain them If I let them turn...

PROS: Lightweight, Ergonomic Design, Versatile, Strong Construction

I guess I should have known from looking at the photo. When they arrived, I thought, "I don't want to put that cheap plastic on my bike". So they are sitting in my parts drawer because I don't ever get around to returning stuff.

These started out great until they snapped on the third ride. I wasn't even on them when they broke. I just heard a loud pop, looked down, and one was broken.

PROS: Lightweight, Price, Comfort

CONS: Weak Construction, Break Easily

I like the feel and look, but the quality and/or design is not adequate for the task. These should not break under minimal torquing (i.e. enough so they don't turn on the bars. I agree with the other reviewer, if they can get the design and build right, these are good bar ends, but not in the current form.
