Oh, and "temp" bike is not quite how I'm looking at it.
I have a road bike, and I need / want a fixed gear and a good city / errand bike to replace the one I have which is dying a slow death.
I thought I was going to get the Pista first and the errand bike second. I'm just getting them in reverse order, and I'm going to ride the IRO fixed for the summer before turning it over to be my commuter / errand bike / jack of all trades. The Pista will probably have to wait until next Spring now, but that's OK - I'd rather have something fun to ride for most of this summer and wait on that bike a bit.
I think it'll work out pretty well.
