Product Details

Overview & Technology

SDG's Bel-Air V3 Terra Firma is a limited-edition collaboration with artist Johan Johnston (Hasie & The Robots). The saddle blends bold, modern camouflage artwork with purpose-built mountain saddle technology — a 3-piece Kevlar cover printed in Hasie Purple over a traditional nylon base and bumpers for proven durability. The shell features light-weight injection-molded EVA foam for tuned cushioning and a hidden cutout relief under the base that relieves perineal pressure without sacrificing support. Lux-Alloy rails keep weight down (295g) while remaining stiff and reliable; the saddle is also e‑bike approved for modern MTB setups.

Key Features & Construction

This Bel-Air V3 pairs rider-focused details with quality materials: a 3-piece Kevlar-covered top for abrasion resistance, a free-float comfort flex system to allow subtle lateral movement under load, and a wider nose "nose float" platform to aid seated climbing. The slight rear-rise platform provides a secure pocket for sprinting and steep ascents. Notable construction details: • Injection-molded EVA foam — tuned padding for impact damping and low weight • Hidden cutout relief under the shell — targeted pressure relief without a visible top hole • Lux-Alloy rails — lightweight, corrosion-resistant and e‑bike rated • 3-piece Kevlar cover — durable, grippy and printed with Johan Johnston artwork

Fit, Dimensions & Compatibility

The Terra Firma is a unisex 260 x 140mm saddle designed for mountain bikes where a balance between control and comfort is required. The 140mm width suits riders who prefer a slightly narrower platform while the 260mm length gives enough room to shift position on climbs and descents. At 295g it’s light enough for trail and enduro rigs while remaining robust for all-mountain abuse. Rails are Lux-Alloy standard round section and fit the majority of modern saddle clamps and dropper posts. The saddle is e‑bike approved and works with e‑MTBs that accept standard rail saddles. If you use a suspension seatpost or dropper, confirm clamp compatibility with 7mm round rails.

Who This Saddle Is For

The Bel-Air V3 Terra Firma is for mountain riders who want a performance-oriented saddle with a unique artistic touch. It’s ideal for riders who spend long days on varied terrain — climbing, technical singletrack and spirited descents — and need a saddle that balances pressure relief, pedaling efficiency and control. Riders attracted to limited-edition gear or who want to add personality to their bike will appreciate the Johan Johnston artwork. It’s a great pick for trail riders, light enduro racers and e‑MTB riders seeking a reliable, stylish saddle that doesn’t compromise on function.

Frequently Asked Questions

Is the Bel-Air V3 Terra Firma saddle suitable for long rides?

Yes. The Terra Firma uses injection-molded EVA foam with a hidden cutout relief to reduce perineal pressure and hotspots, making it comfortable for long trail days. Ride comfort will still depend on your sit bone width and bike fit, so pairing the saddle with a proper bike fit is recommended.

What does 'hidden cutout relief under the base' mean and how does it help?

The hidden cutout is an internal relief molded into the shell beneath the top cover, so there’s no large visible hole on the surface. It reduces soft-tissue pressure while maintaining top-surface integrity and cover strength, giving pressure relief without compromising the saddle’s feel or durability.

Are the rails compatible with my dropper post clamp?

The Bel-Air V3 comes with Lux-Alloy round-section rails that fit standard saddle clamps and most dropper post heads. If your clamp requires a specific rail diameter or a grooved/oval section, check the clamp specs — most modern clamps accept 7mm round rails used by SDG.

How durable is the printed Kevlar cover?

The three-piece Kevlar cover is abrasion resistant and designed for mountain use, offering better durability than standard microfiber tops. The printed Hasie design is applied to the cover; while durable, avoid harsh chemicals and prolonged UV exposure to maintain artwork vibrancy.

Is this saddle approved for e‑bike use?

Yes. The Bel-Air V3 Terra Firma is e‑bike approved and rated for the additional stresses of electric-assist riding. Always verify that your seatpost and rail clamp are also rated for e‑bike use to ensure system compatibility.

What is the best way to care for the saddle?

Clean with mild soap and water and a soft cloth; avoid strong solvents, high-pressure washers close to seams, and prolonged sun exposure to protect the Kevlar print. Regularly inspect rails, base and bumpers for damage after aggressive rides to maintain safety and longevity.

Buying Guide

When choosing a mountain saddle, prioritize sit bone width, riding position and terrain. For mixed trail riding you want a balance of padding and mobility — a slightly narrower 140mm width like the Bel-Air V3 suits riders who shift position often and need a stable pedaling platform. The hidden cutout and free-float flex provide pressure relief while maintaining pedaling efficiency. Check rail material and clamp compatibility (Lux-Alloy rails are common and durable) and consider weight only after fit and comfort. If possible, test a saddle for at least an hour or look for retailers with flexible return policies to confirm long-ride comfort before committing.
