recently set up a KHS full-susser. turned out to be heavier than expected (26lbs). racing with a bike this heavy is a killer. need to knock 3lbs off. any ideas?

What's the current set-up like?

First place to look could be the tires & tubes - replace fat meaty heavy (maybe even UST) tires with narrower lighter ones and run tubeless with liquid latex (Stans / Eclipse / home made) to avoid pinch flats and give better grip despite running less knobly tires...

This set up is 26lbs? WOW

The frame must be a big part of this weight, as this is a pretty light set up.

KHS xc904r with AVA float RL
SID SL not worth changing to save 200g
x517 + xtr hubs + DT comp spokes + python airlight tires Conti S/Sonics save 300g
XT crankset O.K
XT front D n XTR rear D O.K
EA 70 stem O/K maybe Syntace F99
EA 70 handlebar XT shifters O.K remove indicators
XTR rim brakes O.K
XT chain SRAM PC 89R hollowpin save 50g
XT cassette XTR $$ but save 100g or 12-27T Ultegra for less$
thomson elite seatpost + SLR gelflow saddle USE carbon save 100g
cane creek c2 headdset O.K
eggbeaters O.K

Titec porkrinds grips save 50g approx, tubeless (stans etc) will help too. Can you live with a 12-27T cassette, if so drop the long cage rear for more gram savings.[/b]

Use a SRAM cassette. They are really good. best one as of 2003 models was only about $50 US

well yeah... the frame weighs aabout 6.3lbs.
the rear shock comes with remote lockout.
advisable to change AVA to a normal float R?

That's expensive, but why don't you go for a DT SSD 210L? Lighter and better, best "air"-shock at the moment.

Make sure you check with DT first for compatibility with your frame. It may fit the frame, but if the KHS design relies on the shock as a structural unit, then it's no good, because the eyelets on the DT "float" and thus they are no good for frames that would be flimsy without a shock in them.

That's no problem at all. It works fine in any frame.

It :!: FITS :!: in any frame it doesnt :!: WORK :!: in any frame. If the frame is not laterally stiff enough, and the shock acts as a part of the frame's structural integrity, then the frame with the DT shock installed will be FLIMSY and may actually have issues with breaking of the frame :!: :!: :!: :!: :!:

Never heard of such problems. The DT is constructed to reduce lateral forces. If the frame brakes with an DT, every other shock without ball joints would break before. There are several other shocks which come with standard ball joints to ensure torque-free mounting in the frame as the DT.
