Nago Evo TTR Nack -SC Saddle

Time trialing is tough enough, but if you're sliding around on your saddle, trying to get a comfortable forward position, you'll squander precious seconds. So Prologo used its own ProTour squads over the course of two years to study many versions of their TTR design before arriving at proven iterations, like the Nago Evo TTR Nack. The big innovation Prologo pioneered is Slide Control, which are the cross-wise grooves you see on the nose of Prologo's TTR models. As the name implies, these anchor you in the forward position. You do less work holding yourself still, and that lets every precious watt get to the pedals.

Also, Slide Control is nearly imperceptible when you ride in this zone. And while this portion of the saddle is specifically engineered for riding TTs (softer foam and more forgiving framing girder this portion of the saddle) the rest of the Nago Evo TTR Nack is built around daily riding.

For instance, the semi-round design allows for repositioning more comfortably, and the carbon fiber frame that supports the multi-density foam top is not only exceedingly light, but also compliant enough to reduce vibration transmission. This carries right down to the Nano Aluminum Carbon Kevlar (NACK) rails. Yes, they're carbon rails, but they're more than that. The Kevlar and aluminum reinforce the weave, making it not only inherently good at quelling road noise, but stronger, too, so the clamping force of the post is well dissipated.

The Nago Evo TTR Nack is uniquely shaped. It's not as long as Prologo's Tri saddles, so it's still comfortable for daily road rides. It has a 136mm width. It comes with Slide Control and is available in a 136mm width. It's sold in three color schemes -- Black/black, Black/white, and White/black.
