What is the difference between the 23mm and 20mm road tyres that are available? Obviously there is the issue of width, but in terms of handling / performance / longevity, etc is there a real difference. Should I stick to the 23C or can I try the 20C option?? Any thoughts or suggections will be gratefully received.

For the record I am riding Mavic Aksium wheels and I am currently runnign Vittoria Rubino Pro Slicks 700x23C adn was lookign at  a 20C option. Oh yeah, I am a clydesdale...

For a larger guy 20c may be too small. Rolling resistance is less but there will be a harshness penalty. And at your size you may be more prone to flats or even rim damage. Stick with 23 or train on 25 and use 23 for races.

Thanks for the tip. I need some new rubber and could get a deal on the 20's but no deal is a good deal if the product doesn't suit. Thanks again.

Did some research on 20c tires a while back - all I found was ill-regard and negative reviews. It's probably why you don't see more manufacturers offering 20c tires as well. Stick with 23c.

Nobody that weighs over 140 lbs belongs on 700x20 tires and even that is pushing it. Stick with the 700x23 size or even 700x25 and you'll be much happier.
