What's my frame size?
Road frame sizes: 48 - 63cm (available in 1 cm increments)
Fixed Gear frame sizes: 47 - 61cm (available in 1 cm increments)
We measure our frames along the seat tube from centre-to-centre (centre of the bottom bracket to the centre of the top tube). To determine your frame size, you need to work out your inside leg measurement (in cm).
- In barefoot, with your feet 20cm apart, pull a tube with a diameter of approx. 35mm (or the back of a book) firmly to your crutch, until you can feel it against the bone.
- Position yourself in the middle of the tube. Measure the distance from your crotch/pubic bone straight down to the floor. *Note: try this a few times to make sure you get an accurate measurement.
- For our Road frame, multiply this figure by 0.65 to select your correct frame height.
If your inside leg measurement puts you in-between two sizes, then your upper body should be the deciding factor in selecting the correct frame size. Your upper body dimensions determine your reach; which affects how 'stretched-out' you'll be along the top tube of your bike.
To work out if you have a long or short reach, you need to determine your Ape Index (arm span minus height). Measure your arm span, by standing up against a wall with your arms extended sideways at a ninety-degree angle. Get a friend to measure you from one end of the tip of the middle finger to the other.
If you have a positive (+) A.I. (e.g. your arm span is greater than your height), then we suggest you go for the larger frame size. If you have a negative (-) A.I. (e.g. your height is greater than your arm span), then you will be more comfortable on the smaller frame.
Example: 170cm (arm span) subtract 167cm (height) = 3. In this example, you have a positive Ape Index, and should go for the larger frame size.
For our Fixed Gear frame, we suggest you buy one size smaller. For instance, if your correct Road frame size is a 57cm, you should buy a 56cm Fixed Gear frame.
