No, It wasn't easy to get an FS bike under 25# back then. The S-Works m4 FSR in 2000 was about as reliably light as they got for the era.. Ellsworth was the only other one that got that close. The S-Works has a carbon/magnesium Mars fork, carbon cranks etc..
With the flat pedals and RaceFace bars that are on it now it's probably 25
his old bike was a 24" wheel specialized with an SR fork.. Weighed 36# or so
