I haven't seen anyone build up a bike with this frame yet.  Should be pretty good though, seems to have good specs.

Had a friend help me build a workswell 29er, but this would be my first FS build.  What rear shocks would be compatible with this frame?  It doesnt seem like theres a ton of room for a shock there.

Do you think 140-150mm fork would throw off the geometry too much?

The pivots on that frame look nice, as does what looks to be replaceable threaded inserts for the brake caliper mounting.

I would guess that any shock with the correct spacing, probably 6.5x1.5, would work.  Possibly a Rockshox Monarch.  The frame spec says 100mm of rear travel and recommends a 120mm fork.  You can ask Peter about going to a 140mm-150mm fork but I would think up to 130mm would be okay.  Maybe look at a RS Pike RCT3 130mm.

If you like to have the ability to lock out your fork & shock, I know RS also has a nice twin-lock XLoc Full Sprint remote.  One button locks out both the fork and shock.

A 165/38 mm Rock Shox Monarch will fit.

For the fork... I wouldn't go beyond 130 mm. Based on the geometry, the BB should be around 330 mm with a 120 mm fork. You don't want much more then that. But you need to understand that + size tire feel different and don't require as much travel. Either a 130 mm Pike (standard 100 mm axle is OK) or a 120 Reba (boost required).
