What's you budget? Depending on how much you want to save (both weight and money), the direction of build might vary by a lot. Basically, you can drop weight from almost every item in your list and then some. I'm tempted to list a bunch of options, but instead I encourage you to sift through threads in gallery and MTB subforums and see for yourself what other members do. And don't forget to make a spreadsheet with part weights, it's such a handy tool!

Cheapest and easiest thing off the bat would be the chain. The PC-1 is super heavy. If the crankset and SS cogs can handle a normal 3/32" chain, then switching even to an eight speed chain would save you some weight. Tires and seatpost would be other fairly inexpensive places to drop weight.

Thank you for the reply. I did go through some, but going to spend most of the day tomorrow to look at the details of it.

Budget is $500-750 more. I have already got Race Face Chester Platform Pedals which are 12 Ounces. I think the Niner Boost RDO Carbon are around 545 Grams, which is a litte over 2.2 LBS less than the Rock Shox Reba 29 RL fork. The saddle on the bike is heavy WTB Volt, Satin steel rails at about 316 Grams, so I ordered Ghost Carbon Bike Saddle at 155 Grams.

Going tubless is probably gonna save another 290 grams. Looking at handle bars and seat tube, stem now.....

Change tyres, go tubeless, use an 8 speed chain eBay carbon seat post and saddle, eBay carbon bars and the weight will fall off.
