I had some time to kill, so I weighed some bikes:
This is the 1978 Schwinn Klunker5 I recently picked up, complete and stock:
That is a super heavy bike!
How about my Mongoose Beast, swapped chainring, pedals, cranks, bars and other weight savings(not all upgrades shown in photo):
Lighter than the Schwinn Klunker5!
My Gravity G29 small frame size 29er, rigid single speed:
My Build-Off bike, the 1936 Off-Roadmaster:
Klunker 1, an 80s Hunter cruiser turned klunker during the build-off:
My early to mid 80s Eddy Merckx team Karel Mintjens race bike, full Capagnolo:
Super light for a steel bike!!!
My Walmart Mongoose Cachet fixed gear bike, upgraded to lighter bars, stripped rear brakes and other weight savings:
Really crappy that this stripped down aluminum single speed weighs more than an old road bike.
Last year's build-off bike, Higgins the German Spy, 1956 J.C. Higgins with mega apes:
