Does anyone know where I can go to get my Gitzo tripod repaired - one of the sleeves on the tripod legs are free rotating and not locking so basically I can't extend to max height of the tripod. Looking at the Gitzo website they don't operate directly into Singapore and are using retailers. Do I need to go to HK to get Gitzo repaired which seems to be the closest Gitzo office? Any thoughts would be greatly appreciated.
