The key differences between these two strollers is that the Bob has a lightweight aluminum frame with a good suspension system coupled with the inflatable wheels that help in
damping the road bumps.

bumps and undulations in the
road ahead, and adjusts the suspension to smother them with perfectly calculated
damping.
The air suspension did a slightly better job of
damping out small
bumps and seemed to transmit less
road noise into the cabin, but handling was pretty darn near a toss - up.
Purpose - built Fox Racing Shox are 44 percent larger with 3.0 - inch diameter shock canisters (2.5 inches previously) and nine - stage bypass

road.
The quality of the
damping is such that the car is both tightly tied down to the
road surface and composed over
bumps, potholes and ridges, meaning the tyres stay firmly pressed into the tarmac at all times.
The passive

road more contentedly, soaking up
bumps in that transparent way that only fixed rate dampers seem truly capable of.
The
damping is supremely controlled, holding the car in this lovely zone where you're connected to the
road completely but it's also absorbing all the nastiest
bumps and keeping wheels and body in perfect check.
Sharp
bumps do catch the short travel suspension by surprise, while over really rippled tarmac the Up can get a little bouncy, as the
damping struggles to contain body movements, but this is only really an issue on the most testing of
roads.
It certainly doesn't have
damping to match — it thuds over
bumps without any effort to absorb them and ridges in the
road drag it to and fro.
Only on a bumpy British B -
road does the DB11 feel less happy being hustled because although the fundamental balance remains, the rapid fire nature of the
bumps means the
damping doesn't always have time to really control the long travel between hits.
The fact that the tires are all - terrain instead of being full - fledge mudder rubber help, but the off -
road - focused suspension does an admirable job keeping the body controlled when going around turns and
bumps are easily
damped out.

damped and doesn't crash over
bumps and potholes, the stiff chassis does tend to follow the

The base - spec MKT doesn't get the Continuously Controlled

Germany's high - quality
roads make judgment difficult, but ride quality seemed excellent, the car soaking up the few sharp
bumps we met well, with competent
damping.
Set to standard mode (there are separate modes for access and off -
road driving), the suspension failed to
damp out even small
bumps, leading to a bouncy and jarring ride.
Stiffer front spring rates assist noticeably in cornering, while selective
damping helps to smooth out
road bumps, ensuring ride quality — even on pitted tarmac — is not as harsh as might be anticipated.
In other words, the shock offers a smooth ride around town but provides the proper
damping in high - speed off -
roading so the 4Runner isn't slamming into its
bump stops.
The front suspension decouples the wheel location and
damping functions to avoid compromising comfort under high lateral acceleration, allowing the steering to remain as unaffected as possible by
bumps in the
road.
As for the ride, it swallows most small
bumps whole as promised, although the odd clatter across ridges and potholes in Sport suggests that it's the Comfort
damping mode you'll mostly want on U.S.

damping mode you'll mostly want on Britain's
roads.
The Michelin 215 / 55R -17 low rolling resistance all - season tires do an adequate job of holding the
road, and
bumps and pavement irregularities are
damped well by the four - wheel independent suspension which is further aided by the rigid body structure.
The X5 swallows most small
bumps whole as promised, although the odd clatter across ridges and potholes in Sport suggests that it's the comfort
damping mode you'll mostly want on Britain's exfoliating
roads.
It rides wish a soft, squishy nature that soaks up heavy
bumps and potholes — but the
damping leaves a little to be desired and the ride can become influenced by a jittery subtest on severely pockmarked
roads.
