Tonight was an interesting shift at the co-op.

I had known for some time that the external threading on a Uniglide / early Hyperglide freehub mechanism was 1.37 x 24 - same as English-threaded freewheels and bottom brackets. I'd even used BB lockrings as a guide/shield while grinding down a few freehub bodies to fit 11 tooth small cogs as suggested on Sheldon's site. And I suppose I could have conceived that someone might try to thread a freewheel onto a freehub. But I didn't put two and two together until a customer said "I found the gears, but now the axle is too short", and brought this to the counter:



Not only had they tried to thread a freewheel onto a freehub, but a 9-speed e-bike freewheel at that.

Fortunately, it was easily dismantled with a puller and large pliers.

Then a complaint about a brand-new tube going flat. Turned out this big nasty was still in the carcass, plain as day:



Pulled it out plus several more, explained to the kid how to check and clean a tire, then patched the tube.

Ended up staying late to finish up, and was very happy to have the Ridekick trailer help my tired legs home.
