Just mulling over options for the Rat... I'm not really a fan of skinny superhard tyres, is the main analysis, I don't trust them and I don't like how they feel on anything but smooth tarmac. SO I've got it feeling pretty nice overall but there's just a lot of the time I'm not digging it.
So... My commuter is an old mountain bike with 2 inch slicks on it, and I much prefer it on some of the local roads, and I'm happier really pinning it- again, just trust.
So, I was thinking... I've got a decent spare set of 26 inch disc wheels (lighter than the wheels on the rat just now, they're not svelte). I could sling on a set of Supermotos (for big) or maybe 2 inch Kojaks (for lighter) or similiar, and the wheel size ends up not so different. Will fit nicely into the frame, and disc converting it's not hard. It'll add a little weight in the tyres, but lose almost as much in the wheels... Sure the fatter tyres will be draggier, not sure by how much... And less aero obviously, but I refuse to give a damn about that
So, before I think more- bad idea? Good idea? I've not found any massive drawbacks as yet, other than having to convert to disc. It doesn't need mudguards but I reckon a big set of SKS would fit anyway.
