Hi I've bought a new wheel to go on my bike. So that i can just change my bikes rear wheel when i use a turbo trainer and then use the other on the road. But i didnt realise that the new wheel bought had a freewheel, not a cassette. ( i was clueless till i researched it!) So can I use the wheel with the freewheel on a turbo and then still use my other wheel that has the cassette on to ride on the road? Also my cassette is 13-26 and the freewheel is 13-28. Can I use the same chain or does it need another link in it?
