He did say aluminium. I have an XTC2 frame, weighs about 1700g for 19", the whole bike is 12kg. I'm sure the XTC1 would <11 with the lighter rims, components etc.
All are about 1500-1600g. Since you are after an alloy frame, you're probably on a budget. Get something cheapish and spend more on wheels, fork and drivetrain, where quality and weight matter more.
FWIW cannondale alloy hardtails (F series) weigh about 1250-1400g (depending on size). This is at the lighter end of the scale, and the compatability with lefty forks (from ~1100g) and bb30 (potential to save 100g or so, when better [not FSA] bb30 cranks are released later this year, or run the uber expensive [$900 on ebay, ~$2k retail], crazy nice cannondale cranks means that this would be the lightest whole bike setup, if you had money to burn)
I wouldn't pay good money for a cannondale fork again if my life depended on it, but that is another story.

Hmmm, sub 11 isn't that light for an alloy hardtail. My Cannondale 29er1 (alloy) is 10.5 inc pedals and this year's model (Flash - comes in alloy or carbon) is lighter again. Allegedly there is only about 200g difference between the alloy and carbon versions so if you speced an alloy Flash 26in version with the same bling that's on the full spec carbon version you'd have a sub 8.5kg alloy hardtail...
Even an off the shelf Flash F1 should be sub 10 easily (with its X9/X7 build)...
Thanks, two reasons for alloy:
1. Price.
2. Wouldn't want to dent a carbon frame if I have a big off.
Cheers,

I ride an FRM hardtail made from Easton Aluminium weighing in at 1.25kg. My total bike weighs in at just over 8.5kg comprising Oval, XTR & FRM components and Stans Olympic ZTR wheels.

Supporting C Dunlop's advice on spending your hard earned on good quality spec.
Not really had any big offs on my carbon XTC frames.
However, have seen a certain bloke on a Trance Advanced do a high speed nose wheelie that turned into a clipped-in explosive forward roll with a 180 degree rotation of the bars. The noise of his controls smacking his top tube was like a gun shot. To get the bars back around the right way we had to undo the clamps for one brake and one shifter. That force put a little scratch in the top tube. Were more dents in the rider's knee and helmet (which did its job of protecting rider superbly).
Of course you know your own riding style best - if you are concerned about big offs then having a CF frame will probably make you more tentative about riding and it becomes a self-fulfilling prophecy. Better IMHO to have a alu frame and remove the worry - that way you just have fun riding.
If you really want to save weight - go SS.
Have fun.
Bear - out

You could look at aluminum carbon combination. Some bikes have carbon seat stays or whole rear triangles. price wise, its obviously cheaper than a full carbon frame, but not that much more than a full alloy.
You also get dampening qualities from the carbon, my Jamis Dakota has carbon seat stays and its amazing the difference

Most alloy/carbon frames are no lighter than a full alloy frame. I had a Dakota and I agree the carbon stays give it a very comfortable ride but the frame was still up around 1600-1700g.
Think one of the XTC's is a carbon/alloy combo.

I've just built up a bike for my 11 year old son based on a current model XTC2 frame. It currently tips the scales at 10.1kg.
Some of you have listed some pretty light bikes. Any chance you could list the major components, ie fork, wheels, group-set etc.

My scandium hardtail is around 10.5kg I think. Could push it under 10kg pretty easily, but I'm happy with it like this for now. Full details here. Scroll down to see the new wheels and other things.
It's using the MSC frame from Hodaka, which weighs around 1.3kg. I've had it for 10 years and the frame is still strong.
