I don't think it did, am pretty sure it just came in the one size band as well. I think it was the next model, the 600EX that did come in two band on sizes and a braze on tab.
Will try and check and get back to you.
Looking on velobase that seems to be what I am seeing.
6200EX in one clamp size with the next model being the 6207EX, two clamp sizes and a braze on.
That's not conclusive but I am not seeing any in a search.
Someone might know about converting but it may be hard getting the alignment right.
