170mm long Cranks on 24" trainer

Should be interesting riding this… in a week once I recover from sprained ankle and build up strength in ligaments again… thinking it might be good for balancing on the spot - without forward or backward movement?

Shuffling around parts, I needed new cranks (Cotterless) on the 24" trainer.
In stead of ordering new Cranks (125mm cranks seem to be sold out in Aust.)
I found I could re-use the cranks from my long dead electric bike. Just had to grind off the return that was holding the sprocket on the RHS crank.


Get ready for a massive Q factor. Heel strikes should be a thing of the past.
