ISM

The Typhoon is the workhorse of ISM's seats and it offers the ultimate in comfort with its plush padding. This fine seat works great in all applications whether that's road riding, triathlon, commuting, off-road and/or on your indoor bicycle. You'll love the substantial cutaway that eliminates pressure and the large rear platform for excellent support and comfort. There's also gel and foam padding and long chromoly rails for finding the perfect fore/aft seat position. You even get a spot for hooking the seat on the bike rack during triathlon transitions.
