Question: How long are these in length?
Document: bought these because the matched my bike and are the length I like to use..... seems like a quality product
Quality product. Does not come loose after installation. Adds another resting position, even for long flat rides. Really helps while pumping uphills. I thought it might catch on lots of brush & branches, but this was not an issue during my 30+ mile mountain biking weekend.Does not come with instructions. You will need a hex wrench. Make sure to mount so the bent ends point in (not out away from the bike.) Just check online for pictures to see the approximated mounting position.
this is a pretty simple product. I'm not sure what to tell you other then it is easy to instal and looks good.
otherwise these are amazing for a good racing setup, without using drop bars.
has great feel/grip, easy to install and its true to its weight. made out of carbon alloy so its really light.
got these about a month ago from my (not so) friendly neighborhood bike shop. only got them because out of the 2 options, the other ones suck. i knew that because i tried them and they broke easily. these are so much more ergonomic, and i use them for a more forward pitched riding position on my racing mountain bike. these feel great, give a nice grip, look nice, and they're easy to put on.
You can compensate by moving your brake & derailer levers in towards the center.
While longer bars might be preferable for someone looking for more versatility in hand position, these are an excellent, low-profile option.
What is advertised here are bar ends with lights. What I received were plain bar ends. This item is completely erroneous and should be suspended from sale immediately. See the photo I uploaded.
The pictures here are not for this product, but for another set of bar ends w/ lights.I suspect the favorable reviews came before th original pics were used. Amazon please correct this problem. I'm returning my order today.
Answer: yes
