Review on SHIMANO Housing Stop Down Tube by James Parker

I upgraded my old 12 speed derailleur and needed to replace the down tube derailleurs. I considered the awkward options of either sanding them down or taking the frame to a weld shop, stripping them and then repainting the frame to hide the heat damage. But these small blocks not only saved me all the time and nerves. but also gave me the cable stops I needed. They are built with the usual Shimano quality and attention to detail (mounting surfaces perfectly match the radius of the gear hubs). I couldn't be happier with the results.
