ian you'll find avalanches with a number after them
these are pretty similar to the agressors sold by halfords
not in any way bad bikes ,but i sense not what your after
93- 97 ish was i think the best years for GT's so look for just
"avalanche" usually an lx or similar level build
if your looking for a ZASKAR any will do the lightest (3.1lb for my large)is the 2000/2 models butil with easton tubes ,usually the race models in a
red black gray white COLOURWAY these have disc mounts
and a 3d type dropout
the geometery is a lot more streatched out on the zaskars too
they are fantastic things to ride tho with the right set up
