Our aluminum F550 is an all round powerhouse. Lightweight, TIG welded tubing with an aggressive track geometry it is sturdy and fast and versatile. It oozes modernity and can turn it's hand to the track, the trail or the street.

The F550 goes with just about any component... and we've built a lot of these in beautiful combinations. With 1+1/8th inch 6 series aluminum tubes, it is solid and light. Just 1.6kg for the frame.

Sizing measurements are from the centre of the BB Shell to the top of the top-tube. For the frame geometry drawings click here.

If you're looking for the right frame size, we recommend the rule of standover height. In normal riding footwear, with a shoulder width stance, measure the distance from your crotch straight down to the floor. Divide this number by 1.5 (in CM) for suggested frame height. More details in our FAQ.

Lead Times

We try to maintain a rolling stock of all frames in the most common sizes. We are honestly continually working through a backlog, so lead times may be up to a fortnight to fulfill an order - please get in touch for more details.

If you're looking to build this up into a complete bike, take a look at our F550 Configurator.
