Selle Italia SLR Tekno Flow Saddle
Perfection with a touch of padding.
The Selle Italia SLR Tekno Flow Saddle is an exercise in minimalism, and surprisingly, that's a good thing. You're looking at a saddle that only weighs around 115 grams, but despite its light weight, the Tekno Flow takes advantage of an anatomic cutout and a low-profile Lorica cover in order to deliver far more comfort than you'd expect out of this decidedly firm racing saddle. Basically, if you have your eyes on the checkered flag, this saddle will get you there without compromise.
The SLR Tekno Flow starts off with a 100% carbon fiber base, which is stiff, supportive, and lightweight. True to the SLR designation, this saddle has a 131mm tail width and 275mm length, so it accommodates those with medium width sit bones comfortably. There's a large cutout, which relieves pressure on the perineal artery and adjacent soft tissue. As a result, that pressure is directed to your sit bones (ischial tuberosity), which are far more adept at supporting your body weight. Additionally, they're able to do so without causing numbness during long rides. This principle is further supported by the wide cut out, as it removes pressure from the pudendal nerve. The pudendal nerve is a paired structure, with a left and right nerve. It is formed in the sacral plexus, and in simplified terms, moves down the body between the piriformis muscle and the ischiococcygeus muscles, eventually attaching to the ischial spine. From here it eventually enters the pudendal canal within which it divides off into several branches including the perineal nerve and the inferior rectal nerve. Keeping pressure off of these nerves is imperative to reducing numbness while riding. So, by relieving the very threat of pressure, numbness is eliminated.
A possible misconception about this saddle is that only the perimeter of the saddle has been constructed of carbon fiber. However, it actually shares the standard Tekno's 100% carbon construction, only the Flow features a touch of padding and a low-friction, hard-wearing Lorica cover.
This saddle is supported by Selle Italia's ovalized carbon fiber rails. Not only are they durable and light, but they also provide vibration damping. And although its claimed weight is a ridiculously light 115 grams, this seat is, in fact, rated for off-road use.
The Selle Italia SLR Tekno Flow Saddle is available in 131x275mm size and in the color Black.
- Q & A
This is re: selle italia techno flow carbon saddle with round carbon rails
Can I try it for an hour and still return it for my money back if it doesn't work for me ?
Does this fit into side mount saddle post--either 7mm or 7x9 mm (specialized)
If the saddle comes back new/unused with the packaging intact we can refund you, otherwise we can return it within 30 days for store credit or exchange. As for the rails, they are oval 7X9 and would require a compatible seatpost.
- Familiarity: I've put it through the wringer
This is a fantastically light saddle, allowing for great circulation as well. I love the fit and the look, but have one deal-breaking complaint - the saddle is simply not sturdy enough. After less than a month, some areas of the saddle started to delaminate - particularly near the nose of the saddle - I think from riding "on the rivet" during races. There's simply to much flex for the lamination on the carbon to hold. I wouldn't mind the look of it delaminating, but after a while the gloss portion that separates, also starts to chip off. This leaves some sharp edges that have worn holes in two kits already. I've tried clear nail polish to keep it from chipping off more, but that didn't hold. Next, I'll try some straight epoxy to layer on more thickness, hopefully to save the saddle. That said, none of this should be necessary in a $450 saddle that has never been crashed and is otherwise well cared for.
I can't recommend this one as much as I'd love to.
