Well, u can actually send it in for routine service where revalve & re-oil will be perform to ur adjustables. U can either opt for service & repair when u noticed that the adjustables got unusual noises & doesnt perform up to ur expectation.
If u wanna send it for routine servicing, then ring me up at 016-393 9682 (Andy). Thanx!
