ISM has been working with the World’s best professional cyclists for several years. The Attack is their newest road racing saddle. ISM have narrowed the transition from front to back to 110mm to allow for better rider body movement. The central channel has also been lengthened to maximize and maintain blood flow and comfort in a more slack position. In fact, blood flow testing proved the best ever. Comfort, Power, and Performance. The ISM Adamo Attack Saddle gets you there.
