Choosing Your Size

Selecting the correct size of the frame is very important to ensure the best comfort and performance. We will have a bike fit calculator later on this year, but in the meantime a reliable method for choosing a frame size that will work for you considers the following points:
  • What size bike frame do you currently use and that fits you well? The most important dimension is the length of the top tube, followed by the height of the head tube. Head tube height is important since we only allow up to 40mm space between the top of the head tube and the stem. 
  • Are you a casual or competitive rider? Competitive riders generally use smaller sized frames since they can avoid using any spacers and achieve a more aerodynamic, lower position while achieving the same extension as when riding a larger frame in a more upright position. More upright position is more comfortable for most riders.
  • Seat tube height is not relevant in determining the bike size. This is particularly true for our frames since the Selene frame design is traditional, Helios Aero has an extended seat tube, Magnus has no seat tube extension and the Geos is a sloping frame. In all of these examples looking at the seat tube length will not deliver a valid decision regarding a correct bike size. This is also why we use letters to express the sizes of our bikes.
