Winter grind…

Gorgeous weather whole week, so I tried last week put new chain (3rd) on my bike, and suprise suprise. I had to order new cog.

Old cog vs new after grinding English mud for three winters 😉

Anyway I did hub maintenance, as well. After almost 1 year not looking inside my gear hub (Alfine 8 sp) everything look nice. Castrol ATF oil looks still a bit pinkish, so that’s good sign. This is my third year after switching to Castrol ATF, strongly recommended as Shimano oil is very expensive. I’ll post whole procedure (as I’m doing it) soon but basically I’m using plastic pet bottle and hub on cordless drill to “stir” the oil. Afterwards, again using centrifugal force I’m removing oil excess from the hub (rather than dipping and than leaving for 30 minutes – stupid, my whole procedure takes maybe 20minutes).

The other thing I noticed (which is quite annoying), that cone on non drive side was loose. I don’t know what people are doing to prevent this, but is right pain in the arse. God knows how many times I tighten that…

Happy pedaling spring is just around the corner

(and tensioners looks ugly IMHO)
