[Not2B]

I would like to see parts that smaller teams have trouble with. So I asked myself "If you don't have a lathe and mill, what is hard to do?" and "what do all teams need, and thus lends it's self to mass production?"

And I came up with 2 items.
1) Transmission - which we seem to have 2 good options already, namely the kitbot (affordable - THANK YOU) and AM shifter (bells and whistles).

2) Drive wheels - either a good keyed hub on a wheel, or a hub that allows the easy connection of a sprocket. And cheap. Now there are already several products on the market like this - the battle bots universe has several options, as does the go-kart world. So I don't know if there is a market for these... but if you make them cheap enough... or give us flexible mounting options...

Most other "yearly" parts (Frame, mounts, etc...) seem easy enough for a resource-limited team to handle.
