Een kleine oplage 2009 chickenloops op de Best barretjes heeft een niet goed functionerend quick release systeem. Dus voor de 2009 Best eigenaren.....check it:
We think it's best you check your 2009 chicken loop! A small number of 2009 BEST chicken loops have been shipped with a possible non-functioning quick release mechanism. The problem has arisen where part of the internal section of the chicken loop is injected with "thread lock." A small amount of excess in some cases has seeped out after the injection gluing the eject sleeve to the chicken loop. If you were an early adopter of the 2009 BEST bar or chicken loop you can simply test this by activating the release on the chicken loop and seeing if it releases.
