Even with that I think I'd be walking the whole route. :)
Say 28kph @120rpm. James has got 30x10T I guess so more like 50kph @ 120rpm
How long is the road section and can someone do the rest of the maths with all the assumptions I've not bothered to explain away
That is 34t at the crankset, so 1.7, will be as if you're running an 11-23 cassette with a 40t single chainring! You should consider it for Badlands
