The descriptions of some items on your website mention that shorter/longer variants are available; how much longer/ shorter are they and is there a cost for this?

This option is only available in our top end men's and women's Pro SL jersey and bib shorts and our D2Z encapsulator suits. On these items where the shorter/longer variant is available there is no charge for choosing a variant (just request when placing your order). Longer/shorter variant on the Pro SL jersey means 5cm difference in  body and 2.5cm in short sleeves. Longer/shorter on the Pro SL Bibshorts means 5cm difference in the leg length. On the the D2Z encapsulator suit  the request can be on the lower(shorts) or upper(top) or both.
