An important thing to know is that the BOB Revolution Duallie comes in two models. The regular model and the 12" Aluminum Wheels model:
The regular BOB Revolution Duallie has 2 16" wheels in the back, and a 12" swivel wheel in the front. By the way, 16" wheels are good for jogging, so if all you plan to do is jog, consider getting the BOB Ironman Duallie which has all its wheels at 16" . The regular Duallie comes in navy and orange.
The BOB Revolution 12" AW has three 12" wheels which makes it ideal for shopping and running errands. It turns easier and folds smaller than the regular model (which has 2 16" rear wheels). On the other hand, it is not as good for jogging. It comes in black and navy.
The BOB Revolution Duallie weighs 33 lbs, has an alumnimum frame, and a weight capacity of up to 100lbs.
Here is a review of the BOB Revolution Duallie that I found JoggingStroller:
"I have had my BOB now for almost a year and I absolutely love it! Almost every time I go out someone has a comment about it-good that is! Most people are amazed that it fits through every door-even at the doctors office I can manage to get it in. My boys are now 2 and almost 11 months and they have plenty of room-esp. leg room. I see other double joggers and they don't give enough leg room. The individual, double canopy is great, esp. when I need to cover my younger son and my older son wants the freedom to be able to look around. It is very smooth while walking and running. We took it to the beach last summer and it worked great! How many strollers can you take to the beach? My only complaint-or suggestion for redesign- would be with the infant car seat adapter. It has the bar that the car seat rests on, but then there is really nothing to support it on the opposite end (near the actual seat/canopy). Over time, now that my son is bigger, the unsupported part of the car seat, will fall down, making my son uneven. I always need to check his position and readjust the car seat. The redesign should include another support option to help hold the car seat in place. When he was an infant, I didn't notice it as much. It is the best stroller out there and well worth the cost. Its good to invest in some of the accessories too! "
