I am after a tyre to use on my Tacx Genius with what I think is a 24mm internal rim. I just don’t know how narrow I can go.
It won’t be used off the trainer so minimal risk of falling off the rim even if technically too narrow but it will be run at 100-120 psi.
Not fussed about a specific trainer tyre as won’t have much use, a road tyre is fine, especially if very cheap like a Conti Ultra Sport.
Did I mention cheap?
