The rim width isn't the importnat measurement here, the important one is the bead seat diameter (the
bit inside the rim where the bead of he tyre sits - for what you quote it is 571 mm for 650C (as
opposed to 559 mm for the '26 inch' MTB rim)
AIUI 650C is used by most commonly used by Triathlon riders nowadays.
To answer the OP. It depends on what you mean by 26 inch rim - are there any ISO/ERTRO markings
on the rim?
