As others have said; doable as long as things stay true.
This is a pet peeve of mine; many modern bikes have difficulty with 28mm tires, including so-called "endurance" bikes.
For those of us that ride without team/sag support, and would prefer wider tires a few additional millimeters of space would be appreciated.
On a hard-core race bike, OK. But "endurance" bikes? Gimme a few silly millimeters wider...
