I bought another bike.
Actually I only bought part of a bike. I picked up a Ribble Audax frame and carbon forks cheap from eBay, then with the addition of some standard-drop brake calipers and assorted oddments from the LBS I built it up with most of the parts from my old Schwinn Fastback.
60cm Ribble Audax frame with ITM Spider forks.
Most of a Sora groupset with Ultegra triple chainset and RX 100 brakes.
Cannondale Earth hubs on Mach 1 CFX rims with Vittoria Rubino tyres.
THE stem and bars, Planet-X seatpost and saddle.
Total weight 23.25lbs.
After a quick test ride it feels pretty good. It needs a couple of extras like full length mud guards, a couple of bottle cages, and a computer, but it’s pretty much ready to roll.
Pictures to follow when the weather is nicer.
