I ride for http://www.ticket2ridebc.com who are also the Canadian Commencal, IXS and Spank importers.
So in return for promoting T2R and trying to pursuade people to holiday there, I get team kit, Commencal bikes at canadian trade minus 10%, (so roughly 45% of UK price), Maxxis tyres, trade on IXS equipment, trade on Spank equip, free accomodation in Whistler for 2 weeks.
Basically I holidayed there in 2005 and discussed a marketing proposal with them on how to promote T2R in the UK and they asked me to set up a DH team. It doesn’t really cost them anything to sponsor me, just supplying marketing material. As mentioned above, look for an opportunity what YOU can provide to them.
