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.
( Oysi Inline Skating Chassis wheelbase of 281mm is recommended for boot sizes US 9.5-12 [ EU 42 – 45 ] )
