Size Guide
cycling fit.
Cycling kit runs closer to the body than streetwear. Aero jerseys and bib shorts are sized to compress slightly — order your true measurement, not a comfort-fit upsize. If you're between sizes, size down for race kit, size up for endurance/touring.

Fit notes
- Race kit (skin suits, aero jerseys) — size down if you're between sizes. Compression is the point.
- Endurance / touring kit — size up for unrestricted breathing on long climbs.
- Bib shorts inseam doesn't change much across sizes. Most brands run 9–10 inches.
- If you're tall and lean, check a brand's tall-fit option (Castelli LTD, Rapha Pro Team) before defaulting to a bigger size.
