Cheap upgrade for michell gyro

[gwernaffield]

please note these are shipped with NBR o-rings, you can upgrade them if you want to ,, O-rings come in different compounds different strengths,, the size is 28.5 x 2mm for the gyro,se odyssey ,, 70 duro ,,,
the orb i put thicker o rings on 29.5 x 2.5 or 30x 2.5,, to allow for the weight ,, they are shipped with the std version to help keep the cost down ,, o rings do perish over time and will need to be changed,, when needed,, if you need more just PM me they will only be the NBR ones your receive for the actual cost ,, no more added the springs on the gyro and orb need to be changed when a service is done,,
