Nuna TRVL dubl vs BOB Gear Revolution Flex 3.0 Duallie
These two share a side-by-side layout and little else. The TRVL dubl is $950 and 25.2 lb and folds to 19.75 x 30.5 x 27.75 inches with one hand. The BOB Revolution Flex 3.0 Duallie is $900 and 33.1 lb and folds to 40 x 30.5 x 17.5, long and awkward on its wheels. BOB is a running stroller: its seats take jogging from 8 months, its handlebar adjusts from 34.5 to 48 inches, and infants ride only in a car seat on a walk-only setup. The Nuna has a near-flat recline from birth in both seats and a calf support that raises into carriage position, though only one car seat can attach, on the wider seat, and only a Pipa fits. BOB's Duallie adapters are sold separately for Britax, Chicco KeyFit and Graco SnugRide seats, and the page names only the Britax part. Only a family that runs or hikes with two children needs the Duallie, and it asks 7.9 lb more for the privilege.
Folded, the Nuna TRVL dubl makes a 9.67 cu ft box to the BOB Gear Revolution Flex 3.0 Duallie's 12.36 cu ft. Neither fits a 22 x 14 x 9 in carry-on sizer: the Nuna TRVL dubl misses by 13.75 in and the BOB Gear Revolution Flex 3.0 Duallie by 18 in. The Nuna TRVL dubl is 7.9 lb lighter by its maker's figure (25.2 lb to 33.1 lb). The Nuna TRVL dubl is newborn-ready as sold; the BOB Gear Revolution Flex 3.0 Duallie needs a bassinet, insert or infant car seat for the first months. Nuna PIPA series seats click straight onto the Nuna TRVL dubl; every seat listed for the BOB Gear Revolution Flex 3.0 Duallie needs an adapter.
