When I got my Serotta I put Michlin Pro Race tires on it. I really like how nice and smooth they ride.

For years I used the Continental GP 3000's, now the Continental 4000's.

Both tires come in 650c x 23.

Because I liked the Conti GP 3000's so much I'm thinking of trying the Conti 4000's when it's time to replace the Michlin's.
