Hello all, i just got a 1984 Raleigh Record, frame is in perfect shape the only things i have to replace are the rims. Had a problem last night going out the wheel got so bent it actually was stuck on the back fork. So any way i have another bike at home that i don't use and i wanted to take the wheels off that and put on my new Raleigh. The problem i envision is the cassette, this Raleigh is a 10 speed and the other is a 21 speed. any help would be appreciated.
