I broke a spoke on my SCR3 last night. Instead of rushing to the LBS with the wheel, I thought it was about time to learn to do it myself so I duly rushed to the LBS but minus the wheel and returned with a new spoke and a spoke key Did some googling, replacement looks straightforward, get home and remove the tyre, the rim tape and the old nipple. Here's where the problem starts. The hooked bit of the spoke that hooks into the hub has a flat end and will not fit through the hole in the hub. Have I got the wrong spoke? are the ends different? EDIT: I think I may need to remove the cassette, is this right?
