This is my ultra-light weight road bike - most of the parts are custom and quite difficult to source.
Huge thanks to Nick Crumpton for working closely with me on this project, see his incredible full-custom carbon at http://www.crumptoncycles.com/
Additional thanks to Jason at fairwheelbikes for sourcing exotic parts: http://fairwheelbikes.com/
All told the bike weighs in at 11.9 pounds.
