Modern trail saddle shape, old-school upholstery. The Bel-Air V3 Sensus Diamond was created with Cam Zink and the Sensus crew, pairing SDG's long-running Bel-Air profile with a diamond-stitched cover inspired by classic car interiors.

Highlights

• Bel-Air V3 shape with a slight rear rise for power and comfort when seated
• Diamond stitching raised over a special foam underlay, with embossed logos
• Air Foam padding for added comfort
• Hidden undercut relief under the base and Free Float Comfort Flex
• Wider nose platform to help on climbs
• Lux-Alloy rails; 260 x 140mm; SDG lists 275g

Cover and construction

This version of the Bel-Air V3 uses a traditional base and bumpers. A special foam underlay lifts the diamond stitching for a clean, classic look, and the logos are embossed rather than printed. Underneath, Air Foam padding adds comfort on longer rides.

Bel-Air V3 shape

The slight rear rise supports power and comfort when seated, the hidden undercut gives relief under the base, and Free Float Comfort Flex helps pedalling efficiency while reducing pressure. A wider nose platform helps on climbs. SDG lists it for trail, enduro and XC riding.

Compatibility & fit

The saddle has Lux-Alloy rails. SDG doesn't list the rail diameter on the product page, so if your seatpost uses a rail-specific clamp, ask us to check it first. Fitting is a separate workshop service if you'd like us to set saddle height and angle.

Sizes & options

Both colours share the same shape, rails and dimensions; only the cover colour differs.
