The 8 speed Shimano Alfine hub I've been riding for 10 ten years as finally worn out and I'd like to convert it to single speed. The issue is that the bike also has a Gates belt drive and I'd like to keep as much of that as possible to keep it as cheap as I can.
I'm a bit of a novice when it comes to this stuff but is there a way of building a new back wheel keeping the existing rear sprocket? Or do I need to get a new rear sprocket that fits a single speed hub?
And secondly - the current front sprocket is 60t, the rear is 24t = GR 2.5. I know that's an odd set up for a single speed but what difference would it make if the gear ratio ends up sort of around the right mark?
