13 tooth, 3.1 mm wide

They have a Shimano spline fitting (as used on the Brompton / Sturmey Archer BWR wheel) 

Wheel nuts are included

A new chain is also supplied (this is a QCCHAIN100DR to fit a 50 tooth front chain ring, if you have 44t then you can either remove 2 links or ask us for a 98 link chain. If you have a 54T chain ring then please ask for a 102 link chain)

A new gear cable anchor is also supplied (as this has a different size thread on the Sturmey Archer compared to the SRAM)
