If you're between sizes, we generally recommend choosing the smaller option. It's easier to fine-tune the fit of a smaller frame by raising the seat post or using a longer stem, whereas a larger frame leaves much less room for adjustment.

Build weights are provided for a medium‑sized frame and are intended solely as general guidance. Actual weight will vary based on the selected components and accessories, as well as standard manufacturing tolerances. These figures do not constitute a guarantee or warranty of final product weight, and we may occasionally make minor modifications to specifications without prior notice.
