Retro Newbie
After stripping down my bike I have found that the front's have some teeth missing and the rear cassett is quite rusty... The bike is a 21sp and what i would really like to know is can i just buy any 7 sp rear cassette to replace it or are they specific? And also same question for the front's? Ive never rebuilt a bike before so sorry about the novice questions
