So just to start it off I have experience working on bikes but this has me stumped. I recently bought an odyssey anti gram rear hub. Literally it's been ridden 10 times at the most as I usually ride coaster. So just yesterday I went to my friends house and we rode for the day. At the end of the day we swapped cranks as my cranks were too short for my riding style. I took off the rear wheel and set it to the side as I was changing the cranks. My friend had to go so I left the rear wheel off and drove home. When I got home and went to put the wheel back on it acted just like a lhd hub put on a rhd bike. So you could pedal it backwards and you went backwards. Of course I've always ridden the hub rhd so I just assumed I threw the cranks on the wrong way in my rush to leave. Well they are actually on the right side so I put everything back together again. Now it does it half and half. It'll act like a lhd and then suddenly start working properly again for a few cranks and then switch back again. I'm completely stumped as to what happened as no one touched the rear wheel except to loosen the 2 bolts to take it off the bike. The only thing I can think of is a ghost changed the drive side or something haha. If anyone could shed some light on this it would be awesome. Thanks.
