does it work good with 26 inch mountain bike tires?
A 26in tire will fit. Work good? Not so much, unless you get a smooth tread tire of some sort. I put my 29er on here recently (those fit too) to do a bit of position adjustment. It sounded like angry bees mixed with monster truck tires on pavement. So basically, it will work with any tire down to 24in without an adapter, but I would strongly advise getting a trainer tire or at least a smooth pavement tire.
