Cogs

This is part of my rear wheel. What you can see is the Shimano 105 cassette and the Planet X Superlight hub. The cassette is a 23-11 set-up and that numbers equates to the number of teeth on each cog. For me this is not ideal and want to change it to a 25-12 or 27-12 to make the hills a bit easier.

For the very eagle eyed and bike people out there you will have noticed that the spokes are flat and not round like normal ones. This just helps with areodynamics a bit.
