Juice say they developed their Viking Juice chain lube after Scandiwelsh roadie legend Magnus Backstedt told them how unimpressed he'd been with that his chain was grumbling during Paris-Roubaix. Now, according to the Juice website "Maggy doesnt have to re-oil his chain on long rides. This makes him happy". Well good for him but his definition of a long ride doesn't go much beyond 140 miles, because that's about as long as this stuff lasts for.
Fenwicks Pro Lubricant spray is a useful addition to the toolbox, good for blasting dirt from hard-to-reach mechanisms and cleaning out cable runs. The high pressure aerosol means it doesn't last long though, and it's not the most tenacious lubricant out there. It's better than WD40 though.
This Bio Grease from Pedros is so wholesome you could spread it on your toast. Okay, maybe that's going a bit far but it is at least non-toxic and biodegradable, so you can slap it on guilt free. It's good stuff too, though it does have a tendency to separate in the heat.
