regards the GEBE wheel - of all the engines the 40cc is the most likely to damage wheels.

However, that said, the GEBE system doesnt cause too many problems with the wheels as long as you properly align the sheave.

Its a personal decision. If you worry that you wont be able to set the sheave up then go for the wheel, but most wheels with decent spokes should be suitable.. and you can always replace spokes and such if you need to
