I've seen a lisiting for a used/new (it says only ridden once, a few miles, will inspect in person to make a judgement on that) giant defy 2 2015. The listing also includes Gatorskin tyres, Shimano M520 Clip-in Pedals and and Abus D-Lock. Asking for £500. Does it sound like a good deal?
+1. Warranty tops a 17 quid pair of pedals and bad tyres.
