For sale is a barely used Pivot mach 5.5 XT build with the following upgrades:
I9 Enduro Wheels
Rockshox Pike RCT3 160mm fork
Cane Creek headset (not sure the exact model but comparable to Chris King)
Kashima coated rear shock
Pivot brand carbon handlebars

I do have the original wheels, rear shock and fork (fox 36) if preferred I can let the bike go for $4200, but these upgrades are great, they lighten the bike quite a bit and make it perform better.

feel free to ask any questions, buyer to pay shipping
thanks
