I've convinced a friend to go n+1.
My fixie track bike and my hack fixie (ex single speed) have tempted him off his trek mtb and onto what's going to be a bit of a hodge podge of a hybrid, made from spares and eBay bits. He wants a single speed, but I'm sure I can convince him to go fixed.
It's going to be a bit of a Frankenstein's monster of a bike... light mtb frame, carbon road forks, 26" wheels, slick tyres, long drop caliper on the front, normal on the rear, SPDs, carbon seat post, campagnolo chainset, half link chain and a kore chain tensioner (hopefully not required - aiming for magic gear if possible). I haven't convinced him to get drop bars yet.
He still wants flat bars, but he does like the look of my aero bars.
So has anyone else converted another rider to fixed / ss?
