For sale is a cannondale f29 from around 2014. The frame is in great shape except for a scratch on the toptube. I set it aside a year and a half ago after switching bikes and borrowing its tires. The brakes need a bleed, it needs new tires and it should probably have a once-over. It has stans rims with sram hubs, a sram x7/x9 groupset and magura brakes. When I had it built up a few years ago it was sub-20 pounds and it is a great project bike, especially for someone on a budget.
