I’ve been after a decent new cog for my single speed MTB for a while now. Fortunately absoluteBLACK came up with the goods in this British designed, made overseas narrow-wide CNC machined 7075 Txxx Aluminium cog.
It has a nice and wide 7mm base, costs £29 and looks sweet. The South Downs aren’t particularly abrasive on bikes so let’s see how long it lasts and hopefully their steel versions will be out in time for winter. They come in little wheeled 16t, big wheeled 18t and 24 hour solo 20t size.
