The UP longer more upright geo...I was curious about the exact differences in stack and reach, so I put together a table. (Below.) The Exploro is 4.3mm - 4.5mm shorter stack than the UP in any given size, the reach for the Exploro is 1mm-4mm longer than the UP, and the rear center is exactly 5mm shorter for the Exploro. These are quite similar in stack and reach.
I just mounted some 40mm Clement X'PLOR MSO tires on my UP today. There was about 3/8" clearance to the seat tube, which is enough for dry conditions. The shorter rear center on the Exploro will mean 35mm tires for the same clearance; bigger tires will mean 650B wheels.
(Edited to change the table to a picture.)
