I am receiving a very bad reception.This is a phenomenon in which the product using the 1520-R29RAA-001 hub is passed without a pre-body ratchet.This is a symptom that does not catch ratchet when pedaling.It is no longer possible to process inventory in GKR.Can you send 30ea by air for 152A-11SP12-01 parts?It is a GTM bike, but the hub is GCK production, so we request it.
