Product Information
Full details
The SDG Circuit MTN Ti-Alloy Rail Saddle is a high-performance choice for mountain bikers and competitive cyclists who prioritize power transfer and weight savings. Designed for disciplines ranging from XC to Enduro, this saddle excels at providing a stiff, responsive platform for efficient pedaling. While its low-profile design and firm EVA foam padding offer excellent control and durability, riders seeking a highly cushioned or plush seat for long-distance comfort may find its minimalist, racing-oriented build less forgiving.

FAQs
What is the weight of the SDG Circuit MTN saddle?
This saddle weighs 220 grams.
Are the rails compatible with standard seatposts?
Yes, it uses standard 7mm diameter rails that are compatible with almost all mountain bike seatposts.
Is this saddle suitable for road cycling?
While designed for mountain biking, the Circuit platform was originally developed for competitive road teams and works well for road cyclists who prefer a stiff, lightweight saddle.
How wide is the saddle?
The saddle measures 280mm in length and 135mm in width.
What material is the top cover made from?
The saddle features a durable microfibre top cover with reinforced Kevlar side panels.
Can I use this for long-distance rides?
It is designed for performance; while it includes an under-cut for comfort, it is a firm saddle best suited for riders who prioritize efficiency and movement over thick padding.
Troubleshooting
Saddle creaking during pedal strokes
Clean the rail contact points and apply a small amount of light grease or friction paste to the seatpost clamp area.
Saddle shifting position on the rails
Verify that your seatpost clamp bolt is torqued to the correct specification and that no debris is trapped in the rail channel.

Setup, Compatibility & Care
Installation of the SDG Circuit MTN is straightforward, as it utilizes standard dual-rail clamping mechanisms found on almost all modern mountain bike seatposts.
- Adjustment: Ensure the saddle is level on the rails, then tighten the seatpost clamp to the manufacturer's recommended torque setting to avoid damaging the Ti-alloy rails.
- Positioning: Use the visual markers on the rails to set your fore/aft position, starting with a neutral position and adjusting based on your reach to the handlebars.
- Care: Clean the saddle after muddy rides using a damp cloth and mild soap. Avoid harsh chemicals or pressure washers, as these can strip the protective finish from the microfibre top and degrade the foam padding over time. Inspect the Kevlar side panels for fraying periodically, especially after crashes.
