On our recent tour this was a problem. I didn't want to carry a big cresent wrench and a chain whip so I didn't carry any tools to remove the cassette. This was a real PITA since I broke spokes in parts of the country where bike shops were few and far between.
On hindsight I am thinking that if I had carried the cassette tool I could have improvised something by using a vise and or a big cresent wrench at an auto shop or someone's home workshop.
Is there a way to carry tools to pull the cassette without carrying much weight? The PAMIR ENGINEERING HYPER-******* sounds like the ticket. Has anyone used one or something similar?
