The bike portion of a triathlon is essentially a time trial, which to most doesn't sound all that terrible. But then you add in the swim beforehand. and the run, sometimes an entire marathon, afterwards, and things start to look a bit different. To set it apart even further, in the interest of saving time in transitions, you're often riding the bike in minimally padded shorts. The Selle Italia SLR Tri Gel Saddle with Ti rails ensures that even with mere fleece to pad your nether regions, you'll still be comfortable whether your ride is 40k or 180k. The Selle Italia SLR Tri saddle is designed off of its much appreciated SLR base. It is built from carbon reinforced nylon composite. Incorporating a 30% blend of carbon fiber, it provides rigidity and stability while still allowing enough flex so that road vibration is absorbed. The titanium rails relieve the saddle of weight so that your rig will stay light. The saddle is a narrow 131mm, but this is ideal when you're going to be perched on the nose for the duration of your race. And, to this end, gel padding has been added to relieve pressure areas. In fact, most of the padding was placed on the nose area of the saddle. A channel has been cut into the saddle for relief on the perineal zones while climbing or sitting up out of the aerobars. the length is a generous 275mm for fore and aft adjustability The cover is Lorica which allows it to dry fast after the swim. The Selle Italia SLR Tri Gel Saddle Ti Rails is available in One size in the color Black.
