koopakid · Aug 16, 2007, 05:39 PM

i've got this pink bike that nobody uses but i like the gears. on the left (or by the petals of bike) it's got 3 gears and on the right (by the back wheel) it's got 7. on MY bike it only has 5 gears on the right and i want to swap them out. is there a way that i can take off the sprockets so i can swap them? if not please answer my question so i know.

Dang, I'm off into the weeds. I went reading and seems CSA is not doing well. I guess in retrospect, it's good I never got around to getting one. I wonder what failed them...
Anyway, if everything worked like it's supposed to, I'd be outta work. HA!

thanx for all of the info. i guess it seems too big of a project to do so i'll either just forget it or take it in to a bike shop.

While CSA never really took off...even with their 30 minute infomercial... Trek is now in the auto-shift bike game.
They just came out with a cruiser type bike with auto-shift.
The bike is called "Lime" and it will set you back about 450 clams. (pun intended Cap'n Rich)

you shouldnt just swap, because you also need a new derailer for more speeds

Just a thought.......
try just changing the rear wheel, then using the adjustment screws, open the travel of the rear derailuer for the high and low gears. You may have enough travel to make it work or just swap deraileurs and put on a new cable. It takes less than five minutes to change a deraileur and about two minutes to adjust the shifting.
You don't need to mess with the front chainrings.
