As you can probably tell I am very much a tech head. I love trawling the net and finding what is newest, lightest and strongest gear. On my morning cruse through the fixed.org.au forums I came across links to a new product from Retroshift.
They are basically a way to run traditional down tube shifters on your break levers. The advantages are that they eliminate mud jamming up your shifters if you crash, they are also cheap to replace if that same crash destroys the shifter.
You can shift up or down the whole cassette with one swipe.
They have also been proven in race conditions.
