The original Selle Italia Flite saddle goes back nearly 25 years, and it's been so popular very little has changed. Enter the Flite Flow Saddle, with its pressure relieving cutout, and you have a recipe for a saddle that'll be a favorite in another 25 years. The base of the Flite Flow is a 10% carbon, 90% nylon composite. This higher percentage of nylon, as compared to other Selle models, means a supportive ride that gives a bit to enable natural flex. This helps to keep vibration and road chatter at bay, which means longer, more comfortable rides. The width is 145mm, which is within a millimeter of the original Flite. Selle Italia added a cutout to the saddle that helps to minimize pressure in the perineal artery and soft tissue. With pressure directed away from these zones, you'll put your weight on the more supportive sit bones. This reduces numbness by keeping the blood flowing. The saddle is built upon titanium rails, which also help with road chatter. Finally, the cover is durable Lorica that is low friction and won't snag on your shorts.
