Thanks, Sam. My Raven was brand new when I took the photos in May of this year, though my Arkel bar bag is about three years old. My bell is from VO (Velo Orange) in the US. It has a nice prolonged "temple bell" sound, though it doesn't work so well in the rain. (?!) Bought it from my LBS, which stocks a range of VO items, such as my spiffy fluted alloy 52 mm x 650b fenders (mudguards). VO also make a 90-degree mounting bracket which can be inserted between the spacers on your stem, so that you can mount the bike vertically & parallel to the stem. I had some space on the left side of my short Thorn acc bar, however, so put the bell there. No discolouration after six months of use, and it works fine -- I can reach it easily with my left thumb. Sometimes I ring it when no-one's around, just 'cos it sounds so nice.
