Same thing with the Tiagra I'm currently abusing

I looked it up and the triple rear can wrap around 37t, same as the tiagra. That doesn't mean that it would work but it may be close enough, and I'm certain that it would work with a 26t granny. The only problem is that while the front triple is rather inexpensive, it looks like people want real money for those long cage DA rears.
I'll keep an eye out in case I see one for a reasonable price. Right now the only thing that really needs upgrading are the cheap pedals.
