Re: Lubrication advice needed
- I thought today I remember Aaron mentioning something about gasoline in his shop. I quick search got a result.I probably won't use gasoline after what PJ states down the bottom of the post.

Their oil looks like it has Molybdenum Disulfide. the Shimano Alfine 11 oil has lots of warnings about how toxic it is. Rohloff oil would work in a Shimano hub and Shimano's would work in a Rohloff. For most hubs Phil Wood Tenacious oil is fine and it mixes well with most grease. We like the blue marine grease for the bearings and the gears. No problems using both for years in Seattle. Val Kleitz used to use 90wt gear oil at his Bikesmith shop. We use it if the hub is going to be ridden in freezing weather. However, most shifting problems happen from cables freezing. It doesn't get that cold here often for it to be a problem. Yehuda Moon has a comic about it! We have experienced it here too.

Not just 'flammable', it's actually explosive. In my lifetime I've known two experienced mechanics who blew themselves up "being careful" while using gasoline as a solvent. YMMV.
