MC65 – Oysi

Medium Chassis⁶⁵

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.

Oysi Medium Chassis⁶⁵ 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.)

We recommend the Oysi Medium Chassis⁶⁵ for boot sizes US9.5/EU42 and smaller.

Medium Chassis⁶⁵ with 257mm wheelbase is recommended for boot sizes US 8.5 [EU 41] and smaller.

Medium Chassis⁶⁵ with 269mm wheelbase is recommended for boot sizes US 8-10 [EU 40-43] and larger.

As there is some overlap the general idea is that the chassis wheelbase length would be about +/- 5mm compared to the overall foot length.
