Bob ironman stroller is an official stroller of Ironman Triathlon – for sporty parents that love high-performance and an endurable gear. 

Alignment – It’s the only stroller on the market that has a track adjustment knob – to keep rolling straight. Alignment is a typical concern for the strollers – BOB deals with it better than others, as it is so easy to adjust the front wheel on the fly. 

It’s also one of the lightest on the market: only 22 lbs, great assistance in pushing your little around.

The main sport stroller things: a fixed big front wheel, hand brake and 5-point harnesses. A nice add-on as a wrist strap to help you secure the stroller while walking, rollerblading or running.
