Do you mean 10 speed? You could only have 20 speed with 5 cogs at the back if you had 4 chainrings, which would be unusual if not unique.
Or do you have 20 speed, (2 chainrings, 10 sprockets at the back)? In which case your 5-7 speed cahin would be too thick.0 -
Really sorry 10 sp :P so 2 front 5 back Thx0

So you're just replacing the existing double crankset with another double. I'd have thought all you need is the crankset and BB then.
You might have to move the front mech up / down a bit if the big chainring's a different size, and you'd be best to set up the cable tension / limit screws from scratch.0 -
