Kenda Small Block Eight Pro Bike Tire - High-Performance Mountain Bike Tire for Trail & All-Terrain Riding | Durable Tread for Off-Road Cycling & Commuting

The Kenda Small Block Eights came with my Cannondale SL3 which I purchased in August of 2011 and I have put on about 170 hrs (1,500 miles) on these tires. I purchased a replacement tire for the back, the front still has plenty of tread. Impressive durability!In addition the performance is exceptional in variety of conditions and surfaces. I primarily ride single track with some riding on hard packed gravel, dirt roads and asphalt and in all these conditions these tires inspire confidence. The tire is a great climber as well as provides confidence on technical descents and holds well to hard packed surfaces, dry roots, and large rocks.Another very impressive quality is speed, these Kendas are BLAZING FAST!!! I have been on the trails following friends on much more expensive bikes with better components (Shocks, Hubs) and literally once I get up to speed I watch them crank as roll behind them.Where these tires exhibit weakness is in sandy areas, loose gravel and mud where they feel very loose with little control.Pros:* Durability - (Dual Compound)(Hard center fro speed, soft outside for control)* SPEED!! - (These tires are fast!)* Control - (Inspire confidence on most surfaces - listed above)* QuietCons:* Not great on sandy areas, loose gravel and mud.For the conditions I ride in this tire is Outstanding and would definitely recommend!
