I don't think I am going to get a definitive answer on this, but here goes: I am going to get some new tyres. My old ones were the Continental 4000s. I have seen a good deal for the 4 season tyres, but are these better for me? I will likely ride through the (English) winter here. I tend to do club riding between 40-60 miles on average, but will happily do 100 miles+. I like to ride fast, but don't actually race, but am thinking of doing so in the next season.
I am planning on doing the London Triathlon next year, and also the Club Cingles de Mont Ventoux in June. Which tyre suits best?
Also, I just realised and was surprised (like a donut) to find that my 4000s are 700x20. They sure look sleek and have enjoyed riding them. But I am debating whether to get 700x23 this time. I've heard that 23s are actually faster. What is the deal? Which is correct when it comes to wheel thickness? Any recommendations? Is there anyone out there that rides 20s?
