I put a Pro 2 on the front of my IRO Mark V over the weekend. I wanted to check the rear tube that has a slow leak but then I noticed that the chain was short so that with the chain tension perfect, the hub was essentially 1-2cm from the front of the drop out. I was in a hurry and didnt really look at it long. I guess this is great in case the hub slips forward for some reason, but it allows no room to loosen hub from frame, slide hub forward in drop outs, and allow enough slack to get the chain off the rear cog to remove the rear wheel... which is how I thought you normally changed flats on a FG.

Is there something I'm not seeing about getting the rear wheel off? Should I add a few links to make the chain longer and have the hub sit midways in the drop outs? Should I add a "quick link" so I can disconnect the chain with a flathead? Should I leave the hub where it is and buy+carry around a chain-tool to disconnect the chain everytime?

Sorry for the stupid questions, I just didnt see a real easy way to go about changing a flat tire on the rear of my Mark V. I commute on this thing, so I can't exactly take 30 minutes to change a flat on the rear should I ever have one.
