As this is a Ex-test bike, its worth noting the following:
This bike was used for a magazine test ride, it has some scrapes where the lacquer has came off, but not all the way down to the steel.
See photos for details. The rims are different manufacturers but very difficult to distinguish. Its a cracking little bike in a very sought after build.

As our frame geometry is COMPACT you need to knock 3cm off “conventional” frame sizes. If you want a longer frame, you can go up a frame size without ruining yourself on the top tube.
| Rider Height | Suggested Frame Size |
|---|---|
| 5′1″ to 5′6″ (155-167cm) | S (48cm) |
| 5′5″ to 5′10″ (165-178cm) | M (51cm) |
| 5′9″ to 6′1″ (175-185cm) | L (54cm) |
| 6′ to 6′4″ (183-193cm) | XL (57cm) |
All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can also depend on a rider’s torso and limb length.
