Big City, Bright Lights

Given Joe Lucas' reputation as The Prince of Darkness, the electrical system needs all the help it can get. This little set up gives a 10% increase in dynamo speed, allowing the charge rate to balance the lighting load at lower revs. That can only be a good thing as hurtling about, flat out in second at night is neither big nor clever.

The other thing is that once installed adjustment is minimal and the belt is bound to run quieter than a chain, so one of these set ups is going on the shopping list.
