Due to being a lazy prick I have only just taken out my “mitch hub#15” for a clean and regrease of the needle bearing. The bearings are smooth as silk still and the penrite grease on the needle rollers was like new too. Still the original colour and clean with no hint of burning or breaking down after 24,000 kms and 5 or 6 years in all weather. Regreased and reassembled and promise I wont leave it so long next time Mitchy. Thanks for such an awesome product.
