Our Croozer trailer was stolen last week. We loved it. Unfortunately, the deductible for the insurance was more than the trailer costs to replace. So I got an older Trek unit from a co-worker. Fantastic shape and hardly used. But came pretty bare. It was made by Chariot in the late 90's but nothing has really changed in terms of conversion parts. We are looking for the stroller wheels and handlebar. Chariot wants a ton of money for the wheels and bar. If anyone has spares or has a unit that is dying and does not need the conversion stuff, I would be happy to take them off of your hands. Thx in advance!!
