As you may know, I used to be a loyal fan of Dreamer Design strollers, but they no longer manufacture jogging strollers. I believe the company only makes handicapped equipment now. So, I really don't have any useful parts left since most of what people are looking for either broke on my stroller as well or I was unable to remove it without damaging it. Before you send a request for a part, please consider whether the broken part is one that can even be removed if it were not already broken. Many parts are riveted on, for example.
So, if this leaves you in the market for a new (or new-to-you) stroller, the options may have changed since the last time you took a look. Here are some suggestions that are available NOW:
1. Best Mixed-Terrain Running like you are training for something: Bob Ironman Stroller
2. Best Straight and Paved Road Running as fast as you can: Baby Jogger, 25th Anniversary Performance
3. Best I want one stroller to do everything: Joovy Zoom ATS Fixed Wheel Jogging Stroller
4. Best Inexpensive and good enough for real running: Schwinn Joyrider Jogger
5. Honorable Mention for Brand Loyalty: Kelty Speedster Swivel
Generally I have a strong preference for fixed wheel strollers, but in light of EIGHT years (and counting) of loyal service by my Kelty stroller, I have allowed it on the list.
