There is a guy on ebay that sells nitro shoes ellegis and speedminds for 10 bucks a pair plus 1 dollar shipping per pair. can buy as many as you want since it is buy it now. any shore 26 mm or 30 mm. they usually get there within a week from hong kong. It is the best deal I have found and have bought at least 10 sets from him at different times and always get the right tires and a good deal.
