On-One Inbred 29" winter ssmtb I won't use

Are you thinking of a gear for round here and a gear for a day in the peaks or a pair of gears to do that in one go (if that makes sense?)?

28:20 seems kinda low. I know a couple of people who went down that route when they were training for ridiculous long distance/loaded stuff, their thinking was it would be easier on the knees over several days/they'd make up the time in other ways. In the end they both ended up doing their things with gears 🙄.

I don't think I ever went below 30x21 on my karate monkey, but I was younger, stronger, had less commitments, could easily catch the train out into the hills for a fiver and it was pretty much downhill all the way home.

Edit: I might still have a bunch of spare cogs and chainrings if you want to try a few things out before making purchases.
