I need some new tyres for my commuter,
it's currently got the 700 x 23c jobs that came on it, I've gotten on OK with 25's on my other road bike in the past, I reckon the frame and fork have got plenty of clearance for a 28+.
So I'm thinking bigger will be "Better" comfort wise but I don't want to make the bike a draggy nightmare, for all their faults the current tyres do roll reasonably well.
Anybody got any experience based input on the Drag/Rolling/Comfort/flat resistance benefits or drawbacks of using 25 Vs 28mm tyres?
What about mixing tyre sizes? F & R?
