New tires on. I like the look of the tanwalls on this bike, but these will do for now. Plenty of clearance now, and not so small that I'm seeing any issue with handling or pedal clearance. If a good ride bears this out, then I suppose I'll go ahead and go tubeless with 'em.
On my other Montague, a Paratrooper, I had to lay a .5mm spacer under the disc rotor up front, as it wasn't possible with those wheels to avoid either brake rub, or a light spoke brush on the brake housing. The fix seems to have been enough, and it is also waiting for a good test ride.
