The titanium-alloy rails, low weight and excellent performance easily justify the price
The USA-designed SDG Circuit is the lightest saddle on test, but it doesn’t compromise ride comfort.
On first inspection, the minimally padded top, mated to a twist-free shallow base, had us expecting a stiffer, XC feel.
However, during tough rides over lumpy ground, the SDG chassis excelled at absorbing vibrations and bumps, and maintained excellent rider comfort.
A broad cut-out in the base ensures the Circuit folds in towards the centre when loaded, and together with perfectly positioned padding, it always felt very supple and soft.
Kevlar-covered edges along the sides proved tough in mud and grit throughout the winter, and even withstood a couple of huge crashes, which bodes well for long-term resilience.
We like how the SDG has a coarse, textured material that acts as a gripper to stop muddy shorts slipping around.
This keeps you feeling well planted while shifting position. It’s also comparatively low-profile, which may help you achieve a fraction more clearance if your frame has a tall seat tube.
The titanium-alloy rails, low weight and excellent performance easily justify the SDG’s higher-end price. Just don’t expect super-plush padding as well.
