And yes, I'm weak. Out of shape because I had kids and haven't ridden regularly in 2 years
I did do a 110 mile ride recently, but stopped a lot. Averaged 10 miles an hour
I'm switching to shorter cranks because I'm old and the knees need protecting. But shorter cranks bump up your gain ratio (ie feels like you've geared down) and aren't the best for climbs
