I haven't run studs in the past 45 years but do have the Top Contacts. Very, very grippy tires. They are ridable in most ice conditions. But on dry pavement, they are hard work. I rode the Worst Day of the Year ride last year on then, knowing they would be fully in their element 1000' above Portland. Well, the ride got changed to all within the city limits and down low. Nothing frozen. Wow, was trying to keep up with anyone on regular tires hard! And I am not talking about the Lyrcra crown with their CF bikes. I'm talking the women in basically street clothes, steel bikes and fenders.
Oh, those tires are called 37c (38? I'd have to look), but they are a skinny 37c. The same width Paselas are much fatter tires. My fenders don't lie.
