If your internal rim width is 15mm you could go 23mm, this page summarises it, the table at the bottom simplifies it. You'll gain a wee bit on speed but that might be weighed out by discomfort, Id be tempted to go for the middle-ground, which will definitely fit 700x25just a quick one guys my tyres are 700x28/32c can i replace these with different size tyres if i wanted too? ie 700x 23 etc.. dont really understand these numbers and why so many diffarent ones on road bikes?
