Primo 2 WPNT is 3T's carbon all-road and gravel bike with a road-inspired geometry, sold on 700c wheels with the option to switch to 650b and bigger tyres. 3T quotes stack without the Apto cable cover; the actual stack is 15 mm higher than listed on every size. 3T does not publish the fork offset or trail. 3T does not publish fork offset or trail for this bike. The offset used here (50 mm) is worked out from 3T's own stack, reach, head angle, bottom bracket drop, chainstay and wheelbase, which pins it to within a millimetre or two, but it is not a published figure.
