Needed to buy a replacement Grips for my bike (the Mantra). They're a solid set of grips - the only issue is that the length of the grip is a bit longer than the handle itself - there's about a quarter inch of open space that causes the grip to fold over the end of the handle, which over time, causes the grip to rip. If the grips were a bit shorter, this wouldn't be an issue.
I bought these handlebars to replace the stock bars on my Mantra V2, I wanted a little more height. Works great!
