This is wrong 48x17 on a 650c wheel is around 68GI with a 23c tyre, that's a perfect gear ratio.
Perfect for who?
I am fairly fit but 68 is slightly too high for my terrain and my perfect ratio is around 64. For riding slowly and up hills 68 is on the high side for someone who may not want to be pushing too hard.
