Carver Rigid Fork

[mtbclimber]

Starting a rigid 29er build, I'm looking for a light weight rigid fork and crankset which
will be a 1 x 9 or 1 x 10 setup. The two forks I've come up with is a Carver tapered carbon fork listed at 560 grams and a Niner carbon fork listed at 565 grams. I'd like enough clearance to run a 2.35 tire if needed. Unsure of a crankset, my frame is BB30 press fit and would like to use a 104 bolt pattern.
Any suggestions would be great.
