Description
The Sadelio is made for riders who spend hours in the saddle and refuse to be sore. Its 3D-printed surface is made of hundreds of open lattice cells that spread your weight over independent flexible micro-zones, where a classic saddle puts everything on two sit bones and your soft tissue.
Indoors, that matters even more: your bike is locked in the trainer, you barely move, and the pressure sits on the same spot for the whole session. The lattice keeps it spread out, from the warm-up to the last interval.

Where is it made?
Sadelio is a French brand. Each saddle is 3D-printed by our manufacturing partner, which specializes in lattice printing, and ships directly from its production warehouse to you. That's how we keep a pro-level 3D saddle at a fraction of the pro price.
Outside, you'd be fine. On the trainer, you're squirming by minute 40.
It's not in your head. On the road, your bike moves under you, you coast, you stand on the climbs, the wind cools you down. On the trainer, none of that happens.
- Your bike is locked: no micro-movements, the pressure never shifts.
- No descents, no coasting: you pedal seated for the whole session.
- No wind: heat and sweat build up exactly where you sit.
- So you stand every ten minutes, and the workout falls apart.
Winter is five months long. Your saddle shouldn't decide how long you ride.
Foam compresses. A lattice spreads.
"Comfort" saddles add foam, and more foam just sinks and pinches again. The 3D structure does the opposite.
Micro-zoned support
Hundreds of independent cells flex where they need to: firm under the sit bones, soft where it's sensitive.
Wide central channel
Takes pressure off the most sensitive area, the same principle as the pro 3D saddles.
Open, so air gets through
An open lattice, not a closed pad: air circulates under you, and it rinses clean after a sweaty session.
From your first Zwift race to spring's first road ride.
Zwift races & group rides
Seated efforts at threshold for an hour: the lattice keeps the pressure spread so you stay in the bunch, not out of the saddle.
Structured workouts
ERG mode, sweet spot, long endurance blocks: the sessions where you barely move are exactly where a lattice makes the biggest difference.
Then, back on the road
Same saddle in April. Or take the Duo: one on the trainer bike, one on the road bike, same feel all year.
Pro 3D technology. Not the pro price.

Everything riders ask before buying.
Why does my saddle hurt more on Zwift than outside?
Because your bike doesn't move. Outdoors you coast, stand and shift around without noticing; on a trainer the pressure stays on the same spot for the whole session, and there's no wind to cool you down. A lattice spreads that constant pressure instead of concentrating it.
Will it fit my trainer setup?
The saddle goes on your bike, so it works with any wheel-on or direct-drive trainer. Round 7 mm rails fit 99% of standard seatposts. Smart bike or proprietary clamp? Send us a photo before ordering.
How do I know it suits my anatomy?
No saddle fits every rider without trying, which is why you get 30 days of real rides. At 250 × 150 mm with a wide central channel, it suits most sit-bone widths (100–130 mm).
Men or women: is it the same saddle?
Yes, it's unisex, like the pro 3D saddles from Specialized and Fizik.
Harder or softer than foam?
Neither: progressive. Soft on the surface, firm underneath. It doesn't flatten over time like foam, and there's no break-in.
Where is it made?
Sadelio is a French brand. Each saddle is 3D-printed by our manufacturing partner and ships directly from its production warehouse to you, tracked from dispatch.
Will I pay anything on delivery?
Shipping is free. Depending on your province, GST/HST may be collected by the carrier at delivery.
How do returns work?
Email contact@sadelio.com within 30 days of delivery. Option 1: keep the saddle, send a photo and a line on why, and we refund 50% within 2–3 business days. Option 2: send it back (return postage at your cost) and we refund 100% within 2–3 business days of receiving it. One trial claim per customer.
