Many racers train on clinchers and race on tubulars. It makes sense, unless you ride the Continental Sprinter Tubular tire. The Sprinter is light enough for race day, but it’s also durable enough to use in training, so it truly is a great all- around tire. To achieve this, Continental uses four layers of polyamide casing to protect against punctures. Even so, the Sprinter provides the legendary ride and feel of a tubular tire. It’s made with natural rubber and Continental’s Activated Silica Compound, which enhances the tire’s grip on both wet and dry roads.
