Does anyone know if there is a real difference between Alpha Q X2 tandem fork and the std Alpha Q carbon?

Lots of Alpha Qs available online for about $400 less than the Q X2 tandem... and the specs (shape, length, rake and weight) look just about identical.

I have the tandem version on our tandem.
I would assume there is a difference.
AS far as I know these forks are no longer made.
You could ask Calfee since they used them until they were no longer available.

We've had the AlphaQ X-2 version on our Zona tandem for the past 40,000 miles.
Don't know what the differences in specs are between the tandem and non-tandem version.

Each Alpha Q product was a bit different, both in design and dimensions, hence the GS10, GS20, GS30, etc... and came with their own maximum load rating, usually much lower than the X2's, e.g., 225 lbs max for the GS20. The X2's were more closely related in design to the CX forks but without the brake bosses, longer steerers, etc. Even if you were a super lightweight team I'd pass on using any fork that was not designed for use on a tandem and that carries that tandem designation. It won't necessarily fail catastrophically, but will not be stiff enough to track well, will likely begin to develop stress cracks and need to be pulled off prematurely. Frankly, even the X2's are the most robust forks in the world, which is why the newer tandem-specific forks developed by Co-Motion and Santana are a lot more robust. ENVE's 2.0 is on par with an X2.
