Calli-Rings SWISS MADE 38 millimeters
Swiss excellence for movement.
Manufactured in Sierre, Valais, in partnership with Workshop 4.0, Calli-Rings Swiss Made embody a demanding vision of calisthenics: simplicity, durability, and performance. Made from FSC-certified birch wood, these 38mm diameter rings offer a natural and comfortable grip, designed to accompany both beginners and high-level athletes.
Why 38mm? Traditional gymnastics rings measure 28mm in diameter, a standard designed for sports competitions and hands trained since childhood. Calisthenics, however, caters to a much wider spectrum of athletes, with higher training volumes and more varied movements. The 38mm diameter better distributes the load on the palm, reduces flexor fatigue over time, and improves control during strength elements. More comfort, more precision, more longevity in practice.
No resin, no aggressive varnish. Only noble wood, treated with respect. Covered by a 10-year commercial warranty against structural manufacturing defects.
Swiss Made. FSC. 10-year warranty. Made to be used.

Calli-Rings Warranty
Our wooden rings are covered by a limited commercial warranty of 10 years against manufacturing defects (structural integrity, laminated wood construction, delamination). Our parallettes benefit from a 5-year warranty under the same conditions.
These warranties apply under normal use, within the limit of the SGS Switzerland certified load — 300 kg for the rings, 150 kg for the parallettes — and become null and void in case of unauthorized modification, repair, sanding, or drilling.
Not covered: normal wear and tear, natural variations in wood (grain, shade), as well as straps, Velcro fasteners, rubber pads, screws, and other consumable or wear-and-tear accessories, which are only covered by the applicable legal warranty.
