Oysius Medium - Bubblegum Pink

  • Hedonskate Winter Beanie

While adhering to the same performance design principles as the original Oysi Inline Skating Chassis, we’ve packaged a similar skating experience into a more compact form to complement smaller boot sizes.

The Oysi Medium Chassis 65 is designed to ride flat using a combination of 65mm outer and 58mm inner wheels and is available in either 257mm or 269mm wheelbase lengths, both providing the same thoughtfully contoured groove centered between a 127mm middle wheel split.

Effective use of the space beneath your feet yields an uncompromised groove, responsive control, and low profile.

Featuring a 5.7mm lower ride height and 4.2mm reduction in groove height, the Oysi Medium Chassis65 is designed to hug your soul.

Designed and Manufactured in the USA. (Sold in Pairs.)

Please review our Quick Reference Rocker Table and utilize our Rocker Calculator to help with determining your wheel selection.

Fitment of 63mm through 68mm wheels on the outer axlesRequires Modification of the Soul Plate to create a clear recess above the chassis mounting plane. 

Please note that the inner sidewall spacers usually require a press fit. Demonstration of how to do this using common tools is provided here – How to Press Fit Spacers
