Having made a mistake in choosing a flat barred Cannondale CX4 as my commuting bike last year, I've just finished converting it to dropped bars, and I reckon it improves it no end.
The one thing I feel could still be done to improve it is to fit a set of narrower/slicker tyres once the frosts have cleared. The bike is currently fitted with a set of Bontrager 35mm tyres with a heavy groove (the shop switched the cross style 37mm tyres that came as standard for me). The rims are Maddux 3.0 disc and there's precious little information about them on the web.
How narrow a tyre can rims of this style take? I reckon I could probably fit 32mm kojaks or gator skins, but ideally I'd like to drop this to 28mm tyres if I can. Any thoughts or experiences on doing this would be greatly appreciated.
