As the wait is long we can meanwhile share ideas about the build; I want to do a light build to make it capable to go uphill, I believe the possibilities of this bikes will exceed my skills downhill so I don't need to work too much on this.
My idea is to do 150-150 mm excursion, fork maybe a Pike, rear whatever is light, cheap and locks properly; for the wheels I was thinking actionsport.de , funworks 28 mm alloy rims and hubs, approx 500 eur and around 1650 grams, but now I discovered BTLOS carbon wheels, more expensive but probably they worth the extra money. Some other ideas for wheels? Favourite chinese company?
Groupset I prefer shimano XT, brakes also XT or formula cura; I see nice knockoff saddles on aliexpress, are they acceptable?
