Two month old set of 120mm rebas serviced last weekend. As stated, nowhere near 5ml of oil came out of each lower leg. Foam rings as dry as a nun’s. Could have been that the oil was working its magic elsewhere, but it doubt it. Very little fork grease left on the seals as well. Good job I had a look, really. The tit who built them at SRAM also folded both foam rings over on installing the lowers, so I guess it might have been a Friday afternoon build.
With only 5ml in each lower, I think I will be servicing these three times a year. However the service is pretty easy (when you can get the lowers to release), so not too much of a drama. My frame is straight steerer, so I need to get a good few years out of these forks.
