This is a 6 speed hub

We will be supplying a 16-tooth and a 13-tooth sprocket with the BWR which, with a 50-tooth chain wheel, will give the following distances of travel:
Gear 1: 33.0 gear inches (2.63 metres along the ground)
Gear 2: 40.5 gear inches (3.23 metres travel)
Gear 3: 51.5 gear inches (4.11 metres travel)
Gear 4: 63.5 gear inches (5.06 metres travel)
Gear 5: 81.0 gear inches (6.45 metres travel)
Gear 6: 99.5 gear inches (7.94 metres travel)
This represents a gear range (top gear/bottom gear) of 302%; by comparison, the current SRAM 6-speed arrangement offers a range of 215%. Like our existing 6-speed offering, however, the gearing may be raised or lowered by fitting a 54-tooth (+8%) or 44-tooth (-12%) chain wheel in place of the standard.

I could certainly make use of the 99.5 gear on the flat.
