THIS IS A VINTAGE NEW OLD STOCK SHIMANO 333 // 5 SPEED FRICTION SHIFTER. IT IS STEM MOUNT CLAMP ON. I BELIEVE THIS IS A 1-1/8" INCH OR 28.6MM. THE CLAMP IS MADE WITH STEEL METAL AND THE LEVER IS ALUMINUM I BELIEVE. IT STAMPED SHIMANO - 333 ON IT, IT COME WITH THE INNER CABLE 48" INCH LONG AND THE WHITE CABLE THAT STAMPED SHIMANO 43" INCH LONG, THE WHITE CABLE MIGHT HAVE SOME TINY YELLOW COLOR FROM OLD AGE BUT LOOK FINE. IT IS NEVER USED SHIFTER. I GOT THIS SHIFTER FROM A OLDER BIKE SHOP AND THIS IS NO LONGER SOLD IN STORES ANYMORE.
