Of course it is. Look around here. Also look at the 22 pound Air 9's and add 1.1 pounds and you are there.

It will not be cheap though. Light is not always cheap. Bang for the buck? Start with wheels. Carbon fork, then look at things like seats, seatposts, stem, bars, and go visit the weight weenie forum. The formula is always the same. An MCR in a medium is 4.3 pounds. That is pretty good for a steel frameset. EMD is 3.5, Air 9 is 3.2.

Good luck.

Easily done if guys can get RIP9s to 27*lbs and JET9s to 25*lbs, see now reason why a frame that weighs several pounds llighter should be a problem.

Sure is easy, mine is 26lbs and this weight includes the tail-light, Blackburn Delphi 4.0 computer, bottle cage, big volume pump, AY-UP light fittings and a tube's worth of rubber around the chainstays.

Build is a Medium MCR frame.
*Niner alloy flatbar (620mm width)
White Bros Rock Solid fork.
Chris King headset
Thomson 90mm stem
Thomson post 410mm
*Fizik Nisene saddle
*Oury grips
*Formula K18 brakes
*X9 shifters and rear mech and SRAM cabling.
SRAM 990 cassette 11-34T
*XT front mech and crankset
*Crank Bros Candy SL pedals
*Velocity Blunt wheelset
*Maxxis tyres (Ignitor) and tubes.

I've highlighted (*) the bits where I think weight savings can be made.

As you can see, you shouldn't have too tough of a time building a MCR9 under 25 lbs. My EMD9 frame is .6 lbs lighter than the MCR and came to 24.7 with a no bling, all XT build, a REBA fork and BWW wheels. When the Niner CF fork comes out mine will go under 22lbs. Just to go along with the A&W trend of this thread, here's a picture of my EMD

thanks for all the good info

thanks for all the good info, lots of good input. - I'm hoping to build up an MCR with front suspension and a triple crankset. Sounds like getting this in a large and under 25lb will be a challenge, but possibly doable..
