SLR Boost Superflow Saddle

Whether you're toeing the line on race day or towing the other riders on your weekend group ride, the Selle Italia SLR Boost Superflow Saddle is tuned for the perfect balance of performance and comfort. Based on the proven SLR platform, the SLR Boost Superflow's compact shape and impressively low weight puts a modern touch on a classic design. The defining feature is the massive center cutout, which drastically reduces any physical limitations caused by prolonged pressure in the perineal area, making this saddle a great choice for long distance riding and racing.

Selle Italia crafts most of their saddles within a scale in its lineup, and the SLR Boost Superflow lands midrange, just a notch behind the featherweight Tekno verson. It features two different widths, L3 and a more compact S3, both of which are designed for riders with high amounts of pelvic rotation in their pedal stroke. By using Ti rails and a shell comprised of nylon, Selle Italia is still able to achieve an impressive weight, but without any durability concerns or a rider weight limit.

  • A lightweight saddle for long distance riding and racing
  • Superflow cutout for maximum perineal pressure relief
  • Compact shape is comfortable for aggressive riding positions
  • Tuned shell supports sit bones and absorbs road imperfections
  • Ti rails reduce weight without sacrificing strength
  • Resist abrasion with a tough Fibra-Tek cover that's built to last

Great saddle

I've put it through the wringer
True to size

I have one on all of my bikes; I love it. Longer cut out than specialized Romin and a length in between power and romin; the perfect saddle for me.

Really hard

I've used it several times
True to size

Well made and perhaps good for the road, I found this far too hard for long gravel rides (over 1-2 hours). I sent it back after trying to get used to it. Pretty painful.

Too hard on the sit bones? What saddle were you on before? I'm considering swapping out to the standard from the gravel model because there is too much padding on the wings.
