Mountain biking in Nepal - have you been there?

Hi there - question for some really steep hills...

I am heading to Kathmandu, Nepal tomorrow (for work) and want to look into the local mountain bike scene as well.

I'll be over there again in Feb / March 08 and potentially go on on of the guided tours leaving from Pokhara, Jomosom or KTM. Has anyone been there for MTB? How good are the local rental bikes (they use mainly relatively low-tech hardtails with v-brakes etc to ensure parts supply...)?

Is it feasible to take my trusty FSR dually or will it be crushed on the plane?

There are a number of outfits offering guided tours...anyone used them?
