Hope allow their riders to ride basically whatever bikes they want, and put their free Hope parts on them. Simple.
Not technically true either I’m afraid.
As all of the Hope team is owned and funded by Hope alone, with no sponsorship tie in’s, We can basically select whatever bikes we like and Hope pick up the tab, and build them up in factory parts. The bikes are owned fully by Hope and at the end of the line are either sold to refund new ones or given to riders to sell as part of their contract.
Obviously Hope have industry friends and can buy certain brands at better rates, so that’s what is normally selected. Ie. the XC team are now all on Scott bikes, before it was Giant. The Enduro lot are normally on SantaCruz/Yeti and the downhill are normally Spesh.
