  1. Thanks Bubbrubb for asking. 44,000 Chariot Trailers are recalled in addition to 70,000 trailer conversion kits. I added that info to the article.

  2. The Chariot recall has been out for 5 months. Your local chariot dealer can order the parts and install them in 5-10 minutes, easy fix.

  3. The Chariots are great trailers I have had one for years. Pulled many, many miles on and off road. Love that thing. I’m sad my kid is just about getting too big for it now.

  4. @plum: about the same time we stop referring to pedals as clipless. It is what it is, who cares what its called.

  5. A very similar stem, if not identical apart from a constant dia central carbon section, was recalled by another brand years ago. I still have one somewhere – tbh it looked so dodgy I never fitted it.
