They are the sole importers/distributors of CB.My Joplin 3 recently failed and they quoted £30 to repair.They serviced/repaired it for free
They said that I could do with a new outer sleeve as they'd replaced the guide block but there was still lateral play because this wears quicker than guide blocks and new sleeve would cost £30.TBH the post is 3 years old and the play doesn't bother me now.
Very helpful and good to deal with
