The Attack is ISM's newest road racing saddle. They 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 yet. If you have trouble with numbness, loss of blood flow or discomfort try one of the ISM saddles many riders are raving about.
ISM saddles have a rather unique shape with a forked nose designed to transfer your weight from soft tissue areas to the sit bones for better skeletal support. ISM saddles are particularly suited to relieving pressure for both aero positions on a TT/Tri bike as well as low, streamlined road positions. Over the years, ISM has seen success with Ironman wins, Olympic medals, road racing and countless age group victories. Pros and amateurs alike are finding riding and competing comfortable again.
One detail of ISM saddles is the setup is a little different than a standard saddle. Basically, you want to line up the rails to your current saddle. This will put the nose about 2-inches further back and the rear of the saddle about 1.5-inches further back. Also, don't sit all the way back on an ISM saddle. You should be able to see about 1.5-2" of the back portion saddle when in a normal riding position. ISM saddles are set up initially with the rails level meaning the top will slope downward slightly. If you feel like you have to scoot up the saddle, raise the nose slightly. likewise, if the nose is poking you, lower the nose slightly. ISM saddles are a little taller so you may have to lower your seatpost a little.
