Does anyone know how to determine the different Sphere models. I would like to buy a Sphere Competition 2007 but none of the retailers list this item. should I assume that all new Sphere Comps are the 2007 model?

There are and were only 3 part numbers ever for Sphere series speedos:

- #80500 Sphere (original version, >5.5t motor limit)
- #80700 Sphere Competition
- #80750 Sphere Competition TC-Spec

So, the "2007 Edition" of the Sphere Competition is also a #80700. I would assume there are no previous model Sphere Competition in hobbyshops anymore, since the "2007 Edition" started shipping end of 2006 already.

You can recognise the version by a white additional sticker on the front of the packaging which says "2007 Edition".

Thanks for the help! Other than the packaging, is there any way to distinguish between the three models and the '07?
