The GEAR ADAPTOR is designed to mount a (modified) 80T gear onto a solar wheel, where the wheel is installed on a 6mm carbon fibre axle using 10mm flanged bearings.
For details on using the gear adaptor for the driven wheel, see the “Solar Challenge: Technical Guide” section in the “Solar & Solar Challenge Catalogue”.

NOTE: The spur gear (GEAR80/0.5/2.9) needs to be modified with the centre machined out with a 12mm end mill, so that it fits over the GEAR ADAPTOR).
