Frame size guide

We measure our bikes C-C from the centre of the bottom bracket and the intersection of the center of the top tube and center of the seat tube.

To enjoy riding your bike it is important to make sure that you use a bicycle frame size guide to ensure it fits correctly. Riding the wrong size bike which is  either too small or too large for extended periods can lead to  lower back, upper back, neck and shoulder issues along with various leg injuries, mainly knees. Also, it is more than likely that your power output will be significantly reduced, making the ride harder than it needs be.

Of course testing the bike is always preferable but not always possible so use the chart below to work out what size bike is best for you.

Further information is available in Sheldon Brown’s excellent article “Revisionist Theory of Bicycle Sizing“.
