Selle Italia SLR 3D Carbon Saddle Review 2026: A 137g 3D-Printed Saddle Tested

3D-printed saddle padding has moved from novelty to mainstream over the last few years, and Selle Italia’s SLR 3D Carbon is one of the lightest examples of it — a full carbon-railed race saddle built around a printed lattice structure rather than traditional foam.

Key Specs

Weight: 137g in the narrower S3 width, 143g in L3 — among the lightest performance saddles on the market.
Dimensions: 242mm long; 130mm wide (S3) or 145mm wide (L3).
Rails: full carbon, 7x9mm oval profile.
Padding: Selle Italia’s Carbon DLS 3D-printed lattice, with differentiated cushioning zones rather than a single uniform foam density.

Ride Feel

The Superflow centre channel relieves perineal pressure on longer efforts, and the profile is neutral (flat) rather than curved — meaning it doesn’t actively correct your pelvic tilt the way some ergonomic saddles do, so fit still depends on your position on the bike. Reviewers describe the printed lattice as durable rather than gimmicky, with a notably racy, minimal-cushioning feel that trades comfort for weight more than a typical endurance saddle would.

Who It Suits

This is a race saddle first — the flat profile and minimal padding suit riders already comfortable on a firm, low-profile perch who want to shave weight without moving to a saddle with no padding at all. If you’re still dialling in your position or want more forgiveness over a long 70.3 or full-distance bike leg, our best triathlon saddles for long distance roundup covers more accommodating options.

Verdict

Excellent carbon work and a genuinely durable printed structure at a very competitive weight — but it’s a race saddle for riders who already know a flat, firm profile suits them, not a first upgrade to try fit changes with.
