Selle Italia SLR Boost Women’s Superflow Saddle Review 2026
Overview
Most saddle roundups treat “women’s saddle” as a single afterthought category, so it’s worth a dedicated look at Selle Italia’s SLR Boost Lady Superflow — a proper race saddle built around a wider central cutout and sit-bone-matched width options, not just a unisex saddle in a different colour.
Key Specs
- Weight — around 198g (Small) to 206g (Large), depending on size
- Rails — TI 316 titanium, 7mm diameter, claimed 25% more durability and 15% less weight than standard steel rails
- Widths — 130mm and 145mm options, both 248mm long, so you can match the saddle to your actual sit-bone measurement rather than guessing
- Shell — Fibra-Tek carbon and nylon composite, designed to flex independently on each side to follow hip rotation through the pedal stroke
- Cutout — a wide central Superflow channel intended to relieve pressure on soft tissue across the sit bones and perineal area
Why the Width Options Matter
Saddle comfort is overwhelmingly about matching width to sit-bone spacing rather than picking a “women’s” model on the assumption it’ll automatically fit better. The SLR Boost Lady’s two width options let you actually measure your sit bones (many bike shops offer this with a simple foam pad) and pick accordingly, rather than relying on a single one-size shape. Combined with the independently-flexing shell, this is a saddle built to move with you on a long ride rather than fighting your hip rotation, which matters more the longer you’re in the saddle.
Price and Availability
The Selle Italia SLR Boost Lady Superflow is £174.99 at Tredz (RRP £189.99), in stock at the time of writing.
Verdict: Who It’s For
This suits triathletes who’ve found generic unisex race saddles uncomfortable on longer rides and want a lightweight option built around actual sit-bone width rather than a single generic shape. Get your sit-bone measurement checked before ordering — the two width options only help if you pick the right one.
