Never used the cheap ones… But I wasn’t that impressed with the black chili Rubber Queens, they were good but not amazing- very disappointing wet weather behaviour and iffy edge grip, though otherwise very nice, excellent straightline grip, huge comfort, fast for their size, and not too heavy either… Conti really seem to rely on the expensive rubber to make a decent tyre. I’ll be getting another to put on the rigid when it needs a new front tyre, it’s an awesome choice for rigids IMO, but I didn’t stick with it on the bigger bikes.
So I would expect that just like with Mountain Kings etc, the standard rubber version will be pretty shoddy.
