Baby jogger on Chattahoochee trails: Bob Ironman V. BOB Sport Utility

Two differences between the ironman and the others.  (1) ironman is a fraction lighter and possibly less bulky (barely noticeable) and (2) the front wheel on the ironman is fixed.  For us, that was the deciding feature.  The swiveling front wheel makes the other Bobs so much more manueverable and allows it to multi task as both a jogger (it does this very well) and also be more of a traditional stroller on those long family outings. The Ironman really is just a jogger.  I'm sure you could use it as a traditional stroller but the fixed front wheel makes it more of a hassle. 

I have the Bob Ironman. It's a great jogger, light and smooth but the fixed wheel makes maneuvering it as a "regular stroller" a pain so I wouldn't recommend it in that way. As a dedicated jogger, it was quite nice but I'd think you could get the same benefit from a swivel wheel that fixes. Unfortunately my daughter refuses to sit still in a stroller ever since she learned how to walk so the lovely Kona Blue Ironman stroller is hanging in the garage, unused for over a year. I could be tempted to sell it if anyone wants to make an offer

You're right, the Bob Revolution has the swivel/lock front wheel...
