1. On a MTB with 1x gearing, 34T chainring, a 50T sprocket and a 29" dia wheel, bottom gear would be ~20 GI, i.e. slightly higher than some touring cyclists would propose, myself included.AliK wrote: ↑28 Jul 2021, 11:09pm Please can somebody clarify why balance may be a problem as presumably it isn't when these 50/52T are used on mountain bikes? or is it?
Or for that matter on a bike with a Rohloff hub (if I've understood various articles correctly)?
I would have thought balance would be easier based on the logic that at the moment if I go one or two gears up from my lowest gear it is then much harder to balance. ie my balance gets worse the higher the gear is. Or am I not understanding exactly what people are meaning by balance??
2. With a Rohloff hub low gears are easily obtained by choosing the right combination of chainring and sprocket. However, after experimenting, I have found that a bottom gear of 17-18 GI is about as low as I want to go. With a lower gear I find it hard to maintain a straight line which is not a good thing on a busy road. With a heavy load on board there might also be a tendency to keel over or lose ones balance. I would rather get off and walk up really steep hills; I count it as a blessed relief rather than an admission of defeat!
