Does anyone share a rear wheel between bikes?
I'm considering investing in a nice internal gear hub (Alfine 11 or Rohloff). Primary use would be for touring and weekend day trips on a CX frame. But I'd be curious to try it out on my 29er hardtail MTB for dirty weekends, or maybe even on a tandem in the future if I can convince the missus to try it. These other uses would be a part-time thing - at most a few weekends a year - so there's no way I'd buy another hub for those bikes.
Is it totally crazy to consider buying one 700c rim, lacing it up to the hub, and swapping between bikes? I'd have to makes sure the rim width works for touring and MTB tires, and use consistent brake tech between the bikes (disc vs rim). Obviously I'd need to change tires to change roles, but this is a 10 minute job, a few times a year.
I doubt this is at all common outside the IGH world since it's much more difficult to swap a derailleur drivetrain between bikes. But maybe there are other situations where it makes sense?
Anyone do this?
