Form Cycling

Form Cycling saddles are designed by bike fitters — which means every decision in the Throne lineup traces back to the body mechanics that actually determine saddle comfort: sit bone width, pelvic rotation, and the pressure points that cause problems over long efforts. Rather than offering one shape in multiple sizes, Form built four distinct models, each targeting a specific rider profile with purpose-built geometry. The Throne RS, RS2, GT, and Aero each address a different combination of width and riding position, and every model is available in carbon or titanium rail configurations.

At RA Cycles we carry the complete Form Cycling range — eleven saddle options across the four Throne models, covering road, triathlon, and gravel applications.

About Form Cycling

Form Cycling was built from the fitting room outward — founded by bike fitters who recognized that saddle design informed by body mechanics produces better outcomes than saddle design informed by aesthetics. The Throne lineup is the result: four models that address different sit bone widths and pelvic rotation profiles with purpose-built geometry rather than a single shape adjusted across sizes. The Throne GT is designed for wider sit bones with an abbreviated length and open channel construction; the Throne RS targets a 143–155mm sit bone width profile; the Throne RS2 extends that platform wider at 155–163mm for greater support and stability; and the Throne Aero is optimized for the aggressive, forward-rotated position of a triathlon or time trial setup.

RA Cycles carries the full Throne lineup in both carbon and titanium rail configurations. Carbon rails reduce weight for race-focused builds; titanium rails add compliance for long-ride comfort. The range covers road, triathlon, and gravel applications — each model matched to a specific rider profile rather than a one-size-fits-all approach.
