I have a 5 year old Veloflex Record that's been on three wheels. It's now my front track training tire and shows little sign of giving up the ghost soon. When I bought this tire, they only came in 20mm, which I decided was too narrow. This has been, in my experience, an extremely durable tire for an all-out race tire. Now that they make a 22mm I'm considering using these instead of Vittoria EVO's. A bit pricey, though.
Edit: This tire is ridden almost exclusively outdoors. Highly recommended.
