    10 lbs for 1500usd does not sound bad. What were swapped parts?

    Both brakes are modulated . Wheels are solid and spokes highly tensioned . This is a true WW bike btw .

    Seb, your insane! (And I mean that in the best way possible!) If you don't know this guy...he makes a lot of the stuff he uses. I've seen some really neat, and some crazy stuff come across his G+ page.

    I give the guy props for doing something "because it can be done". Great job. What distinguishes a MTB from a road or cyclocross bike though? I have seen numerous "rigid MTB's" with crazy low weight, so if I buy a road bike, place beefy tires on it and give it a flat bar handle bar is it a MTB? In the end, to each there own right? MTB is a very loosely used term these days.

    Exactly. This bike would not last ten minutes on a trail. Oh you used half the spoke count? What a great idea!

    Yet I post up a 21.4lb race-tested XL FS 29er and get zero comments, lame.

    The true is that we are all whining because of the thread title.

    I bet you this rideable bike below is lighter than ALL the bikes on this thread...and is still meeting the requirements to appear on this neck of the woods.

    interestingly also has a saddle...

    So I decided to create the following:

    Eh...what the heck. I'll post up.

    Weight is 20.5lbs ready to ride (including bottle cage and Garmin mount) Not really weight weenie since I don't think I did anything real creative to really reduce weight. All off the shelf stuff with no exotic Euro boutique parts.

    Only weight I really remember is the weight of the frame at 1111gr. Only reason I remembered it is because it came out to all 1's. The fork is 1400 something grams. Can't recall the exact number.

    I'm #145 before gear.

    Nice work. I had a JET RDO at 24lb with SIDs and a few other heavier parts (XT cranks Chris King Hubs etc), but the Lefty seems to make a big difference.

    I still managed to win a few races on it - I was surprised how fast it rode for a duelly.

    Thats light for the forks, I didn't realise Fox were so light. What model are they?

    I guess I may have to post my Chiner up too.

    Its a "Performance" level Fox. It's got the FIT cartridge, but no Kashima or Trail Adjust.

    That KTM is looking sharp. It would be interesting to hear how everyone gets on with the new Fox forks.I haven't ridden anything that comes close to my old Magura Durin...

    The big difference between your picture and *that* one is the bike in your picture has been ridden ;)

    I'm rebuilding my Chiner niner w/ XX1, Sids, dropper which should come in under 8.7kg ready to ride, and will post up when done

    Found a "NOS" 2013 Scott Scale 700RC Nino frame-only that I just completed the full build.

    Weighed in at 18.6lbs (8470g) in the config as you see but without pedals. Very stoked.
