We thought this was an awesome deal at its regular price, but we've got one size large left and have reduced it to the point where we don't even have an adjective to describe it.
At just $650 (reg $900) this 2010 Cannondale 29er single speed should move fast, which is appropriate because it's a pretty fast moving bike. A top notch aluminum frame and rigid, lightweight aluminum fork and a dedicated single speed set up that uses a minimalist dropout in the rear with an eccentric bottom bracket to tension the chain all combines to make a bike that moves quickly. The fairly aggressive geometry doesn't hurt either.
We also don't mind that this bike really, really looks nice. It has elegant lines and a simple paint scheme with well-suited decals. Truthfully, the bike looks and rides like it costs double its regular price, let alone the amazing $650 it's been discounted too. If you're between about 5'10" to 6'2" or so and you want a simple, no compromise cross country riding or racing machine you seriously need to check this out.
