Not a great pic with the overexposure right where it matters, but still enough detail to see what happens to spokes when the chain slips between them and the largest rear cog, while churning up a rooty steep burner of a climb at full pressure. This happened on the tail end of our last loop at Blankets. Funny thing is, I made it through the remaining 2.5 miles or so of trail after this happened with no issues, but as soon as we got to the parking lot, riding flat ground with no power at all, three of the spokes popped right at the hub flange.

Already replaced the entire group of drive-side spokes with thick extra-strong ones. Much cheaper than buying a new wheel. Having a cassette lock ring removal tool and a truing stand has really come in handy. No chain-whip tool makes for an interetsing challenge getting that lock ring off though. Always manage to pull it off somehow though…

    I hate it when that happens. I made my own chain whip out of an old chain and a bit of steel I found laying around – piece of cake (I’m very cheap/poor).

    Thanks for sharing.
