The original model of the Stealth has stainless steel rails for maximum durability and value and has lived on as a time-tested favorite among pros and amateurs alike. With lightweight EVA padding and a carbon-reinforced polymer base. The signature design supports wider and narrower sit bones and helps riders achieve a comfortable and aggressive riding position.
I personally consider the Shimano PRO Stealth Line of saddles to be the most comfortable I've used. Currently, I have this model installed on my gravel, fat and trail bikes. I found it improves circulation, causes less numbing and allows me to enjoy the long days in the saddle even more!
