FAQs
Brand calibration matters?
Hugely. Castelli runs small + Italian. Rapha runs slightly large + UK. Pearl Izumi true to US. Show fit comparison vs your customer's known brand.
Bib shorts difficult to size?
Yes — three measurements (waist + hip + height) plus chamois positioning. Most cyclists size up if between sizes (chamois compression preserved).
