Thanks all.
@Yak it happened because I’m a dumbass who doesn’t look what I’m doing
@aracer think I’d prefer the front to be going faster than the back. Got messy last time I tried it the other way
@Normal Man. My inner racing legend is a fairy tale
@Rusty Spanner. Mine have a big helpful arrow that I chose to ignore
In the end I remembered what happened. It was a real sod to get seated and when it finally did I realised that it was the wrong way round and left it. Couldn’t face that again so put on a spare wheel this afternoon. Unfortunately that’s the one with the single speed hub….
The front is similarly afflicted but I don’t have an excuse for that but when I switched it I found the sealant had dried out and my stock had gone off so cue a rush to the LBS at 520, mainly so they could laugh at me as well but also for some new sealant.
