I just ordered a pair of Cane Creek bar-ends - the grip afforded by the bar-ends should help me climb in the Himalayas (at 10k+ altitude, pretty much any kind of climbing hurts and I need all the help I can get!). I have low-riser bars on my bike for general use, and I am going to use the bar-ends with it.
Besides, there is no such thing as a MTB Fred. Fredness/lack thereof is something you only worry about when you have no hair on your legs
