Yeah, Bike Polo.  Be sure to sign up your club and get yourselves on the map at http://leagueofbikepolo.com/

The bike cave is a community repair shop where you can fix your bike or find replacement parts. Artistic and weird are encouraged.

Novices encouraged.

Usually it's a time-trade thing. Use their shop and expertise to fix your bike- help clean up when you get the chance. They will do straight repairs for a fee I think. Best thing to do is drop by and chat with the gang. All of your questions will be answered.
