AFRayspeed Close Ratio Gearbox
AF's Clo5e Close Ratio Gearbox (34 Tooth 5th Gear)
This is the standard version of thier 5 speed gearbox.
The ratios are 1st (10 - 45), 2nd (13 - 41) 3rd (16 - 38), 4th (18 - 36), 5th (19 - 35).
If set up with 18 - 47 sprockets it will have the following drive ratios, 11.75, 8.24, 6.20, 5.22, 4.81.
This versions very close 4th and 5th makes it ideal for when your speed is often dictated by other riders. i.e. if you are riding at 50mph on a bike capable of 85 - 90mph you'll usually find 4th to tall and the bike chugs, but 3rd is screaming at the upper part of its rev range.
