I've been looking into which tools I need to take with me on longer rides, and obviously one of the issues could be spoke breakage. However, if it's on the drive side, I'll need to remove the cassette. This is probably just me being stupid, but would a decent, new road bike (mine is Trek 2.1 c 2011) with Bontrager wheels have a freewheel or freehub? I have researched it but ended up more confused than when I started, I assumed freehub but then the online spec seems to suggest freewheel! I gather that I need a chain whip if it has a freehub . Thanks in advance for help!
