Much of my riding takes place on dirt/gravel roads, so I usually choose parts for their durability rather than low weight. I'd like to drop some weight w/o resorting to major upgrades like new wheels, etc. Here's what I'm thinking:

Replace King stainless cages with King ti cages (37g savings)
Replace XT rear mech with XTR rear mech (75g savings)
Replace SRAM 971 chain with 991 hollow pin chain (22g savings)

Why not go with a dura ace derailleur for even more savings?

I saved 100g just by changing to a smaller tube size. I am running Bontrager jones cxr(great tires btw, 31mm wide(claimed 34) and 310g each!!). Originally had tubes that were 35/47mm range and switched to 28/32mm. That was the least i ever spent to drop 100g. Look at your tires/tubes and see if you can drop some weight. Plus its rotating weight so it counts more than static weight :smartass: .

Yup, it's amazing how much you can save with that simple swap. In my case I spent $12 and saved 100g or rotating weight.

Also, just go with a KMC X10SL. Not much more money than the Sram, but lighter, more durable, and better shifting IME.

Is it 9-speed compatible?

Yes it works fine with 9 speed. If you'd rather, they do make a 9 speed version, X9SL.

I always throw out there to cut down you post to min insertion if it'll live with that bike. Not quite as safe if you juggle bits around though...

With an 11-34 cassette you could go with a single front ring. It saves the shiftcable/housing, and front derailleur. Instead of the ouerring you use a bashring wich weights the same. And a chainwatcher to keep the chain on the ring. Saves easily up to 150gr.

I wasn’t thrilled with the way the mid-cage XTR mech shifted on the 11-34, so I’m going back to an 11-32, and swapping the 36t chainring for a 34t. I’ve toyed with the idea of going 1x9, but I really like the 46t for paved roads. I’ve may consider replacing the left bar-con with a DT shifter, though.
