I am contemplating a wheel upgrade for my 2017 Specialized Shiv Elite. I am currently running wheels with an external rim width of 23mm and I am wondering whether the break clearance on the Shiv allows for an external rim width of 25mm. It appears that quite a few of the more recent wheels move to that size. I am running 25mm GP 4000 II's tires which should be fine on the slightly wider rims.
