• Oysi Chassis requires specific UFS fasteners (M6-1.0 ISO 7380-2 Button Flange). These are included in the hardware package. Don’t use any other type of fastener when installing the Oysi Chassis to your boot!
• Coping Mode: Place the nylon washers under the externally threaded male axle fastener. This will offset the axle head to extend past the outer frame wall. Contact with the coping will be made first with the axle head before the outer frame wall touches. Don’t use the nylon washers for anything else!
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 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 each of which provide the same size groove.
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.)
Print and Cut out these templates to see how the Medium Chassis65 will fit relative to your boot size.
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.
( Oysi Inline Skating Chassis wheelbase of 281mm is recommended for boot sizes US 9.5-12 [ EU 42 – 45 ] )
These recommendations are relative to foot length (mm), corresponding to nominal shoe sizes, to provide a longer wheelbase than is is traditionally used for these sizes, which is the intended function of the chassis.
There is some overlap, and wheelbase length preference is ultimately up to how each person prefers their skating to feel and of course how each person prefers their setup to look.
PDF files below can be printed out for a test fit with your own boot to see how the different sizes will look and help you to make a decision regarding your preferred wheelbase length.

Unfortunately our bearing supplier is unable to supply us with these bearings……we’re searching for an alternative that provides the same quality, pricing, and would be able to incorporate our plant based lubricant.
