THIS IS A RARE NEVER USED VINTAGE ITEM THAT CAME RIGHT OFF THE BOX / BAG. I FOUND A CASE FULL IN A OLD BIKE WARE HOUSE. THIS SHIFTER COMES JUST THE WAY IT CAME OUT OF THE BOX IN A BAG. THEY DID NOT COME WITH A CLAMP BUT THATS SOMETHING YOU CAN MAKE OR FIND IN A HARDWARE STORE. THIS ITEM WAS USED ON MANY RALEIGH BIKES AND CCM BIKES LIKE THE MARAUDERS, COLUMBIA 1960S AND 1970S. THEY CAN BE MADE TO FIT MANY BRANDS OF BIKES. THEY USED THIS SHIFTER ON MANY DUAL TOP BAR FRAMES AND OTHERS. THIS SHIFTER HAS A COOL SEE THROUGH LIKE GLASS WINDOW FOR SHIFTER PATTERN 1 - 2 - 3. THIS ITEM IS VERY COOL AND CAN BE USED ON MANY BIKES. THIS ITEM COMES WITH THE SHIFTER CABLE. THE SHIFTER 7 INCHES LONG AND ABOUT 2-1/2" WIDE AT WIDEST POINT.
