Yeah. Hard Core Racer. That's you! This bike is the titanium mainstay of our mountain bike line. Each of the 5 sizes available is optimized by tube diameter to provide a stiff and compliant ride unlike any other ti bike on the market. Responsive and stable, the HCR is a cross-country racers dream. Disc mounts are standard, but of course you can run cantilevers if you'd like. Even if you don't race, the ride of a Titus Titanium hardtail cannot be denied. Hop on one and live the dream!
