I was planning a strip and rebuild of my 2 bikes to see how I liked the El mariachi built wit my lightest parts.
Before I started I got to weighing
El Mariachi Single Speed - 26.24 lbs
Frame is 5.8lbs
Ti Kona Raijin 10 speed - 24.72lbs
frame is 4.5lbs
I then stripped them and rebuilt the Salsa with the 10 speed parts, result
26lbs bang on. Could do with being lighter to race on, but I'll work on the gut first...

I've also rebuilt my Ti kona with the Rohloff hub again. 28.75lbs
the rohloff rear wheel with a tyre on is 8.8lbs
