A question we are often asked: Are 27.5-inch tubes already available? Yes, Schwalbe as well as Continental and other manufacturers have them in their programme. Sebastian Moos from Conti says: "However, due to the lack of 27.5" tubes, almost all of our product releases have been run with the normal 26" tubes. This also means that 26" tubes can be ridden in 27.5" tyres. They just need to be fitted a little tighter. New bikes that we supply with tyres are fitted with both 27.5" and 26" (or other brands) tyres. It depends on the original equipment manufacturers and the weight requirements of the product managers." You will find an overview of Continental and Schwalbe tyres opposite.
