I fancy a go at polo. I can guarantee I will be useless.
Any excuse to build another bike.
How about running an Onza 24t trials crank on the left hand side of the bike and a regular crank on the driveside and having a chain with a quick release link for each side?
Would need a bolt-on cog - like those XT conversions you can get.
