My bike is pretty much stock. I have the PureFix Romeo (http://purefixcycles.com/collections...ixie-the-romeo) My bike size is the 47cm.

I don't know what to get, but the stuff I have is the Bullhorn, Drop down bar (with tapes) and a riser bar already.

Everything else on the bike is stock and I was wondering if there's anything I could upgrade to increase performance, and mobility, etc.

Thanks!
