This was quite cheap and its a nice bright rear light. It comes with a bracket for fixing to a rear rack or stays and one for a seatpost. I use it attached to a rail below my seat. You could pay more for a real quality item but for the money this does it for me.
I needed panniers for my Dahon folder. These fit the rear rack and when adjusted fully back - no heel strike. They are well made, waterproof and the quick release system works a treat. I think there is a lot to be said for spending the extra and getting a quality product which looks like it will last for years to come.
I use a Dahon Mu8, a folding bike. I needed panniers which fit the rear rack, don't heelstrike and have room for work clothes and shoes. I tried cheaper makes. Useless. The Ortliebs though - these are robust and well made. For the Dahon i had to set them at the max back. They are v easy to use and I never worry about them. They are the right tool for the job and a snip at £59 for the pair! Job done.
