The classic 'it depends' really. TTT is better in the wet, and possibly longer lasting. The reason, and downside, is that it's an oilier lube. The oil is paraffin oil, so wax compatible but still attracts more dirt. We tend to use TTT in the winter and on commuting bikes, and UFO in the summer. I just did a 300k ride to Paris on my personal bike using UFO and the chain is still spotless - that's the upside to using UFO. They have also launched UFO Drip Wet Conditions recently, which we'll be trying out when the worse weather comes round to see how that will handle the UK winter!

@@EalingBikeMechanic thanks for the info. I’ll share that with my riders. I like your videos… more please!
