Ooh, get you, danger man! Not sure why you're trying to tell me how fast/good you are.
For the record, I've owned many bikes of varying levels of quality. Some of the ones I've enjoyed most were pretty bad, and I didn't like some of the good ones.
OK, dangerous is a poor choice of words. But the point I'm trying to make is you have to be careful riding hard on a bike with 23mm tyres in a way that you don't have to be when you ride 1.75 tyres. Riding a bike like that gives you a different sort of focus because the tyres and wheels are more fragile, no matter what you say.
I love my road bikes, but I'm not interested in riding them now. Even if I did, roads are not as good here in Derbyshire as they were when I lived in Oxfordshire 20+ years ago. I used to do 250 miles a week on road bikes with skinny tyres back then, and I loved it, mostly.
I was never into measuring how fast I was, but I know I used to get to work faster on 25s than I did on 23s. But that's a different discussion.
