Wheels

I'm on a tight budget till I get some stuff done on my R/C cars. I keep having problems with my rear wheels and I've decided to just ditch it and get a new one. It is a 6 speed freewheel thread on hub. I wanted to know if I could just replace the rear wheels and then get a 7 speed cassette and set it up where it dosent use the bigest gear and then later change my deraulier and shifters? Also would I have to replace the front wheel too?

Are you planning on replacing the rims hubs or both? The biggest issue is the drop out width. Your drop outs might not be wide enough.

Ok I'll restate my question. Can I put a new rear wheel with a 7 spd cassette to fit my bike?

If your dropouts are spaced 126 mm (inside face to inside face) then a 7-speed wheel, either freewheel or cassette, will fit. Since your currently using a 6-speed wheel I believe the dropouts are already the correct width. So the answer is yes, you can put on a new wheel with a 7-speed cassette.

If your current shifters are friction or have a friction setting, you can continue to use them too.

BTW, your dropouts aren't 7 inches (178 mm) apart or something is really wrong.
