Joe Murray Bar Ends

No, we don't know why they're called "Dewey". Dewey bar ends are designed by one of the mountain bike racing pioneers, Joe Murray. They are made of Cro-Moly steel. The cinch assembly is made from 1mm wall thickness tubing, that's given a angled cut of 1 1/8 inch length, which becomes "width" on the handlebar. The cinch tube also has three holes in it. Two are to reduce the weight of the bar end, the third is round, and will later be covered by the grip tubing section. The cinch fitting is machined from Cro-Moly rod, that's turned on a lathe, to give it shape and cut it to length. The rod piece is drilled to create the bolt head recess and passageway for the bolt, then threads are tapped for the bolt. The grip tubing has .8mm wall thickness, and a length of 5 1/2 inches. The grip tubing section is miter cut to fit the contour of the cinch tube, then TIG welded to the cinch tube with a 20 degree, from handlebar perpendicular, inward angle toward the front tire. Two inches from the cinch tube the grip tube starts an upward bend. The bend itself takes 2 inches of tubing, and produces a 40 degree upward bend.

With the grip tube welded in place, the cinch fitting is TIG welded to the bottom of the cinch tube then the cinch tube is sawn through to make the clamping mechanism. The entire welded together piece is given a modest polishing then satin Nickel plated, giving it a corrosion resistant surface. Using a 6mm allen head fitting for tightening, the cinch bolt is made from nickel plated steel with 6mm x 1mm thread pitch, is 18mm long, weighing 5.5 grams. The Dewey bar ends come with four chrome plated press-in plastic end plugs for the grip tube and handlebar ends. In an unusual move Dewey bar ends come with self adhesive Black foam rubber grip tape. The grip tape 1 1/8 inches wide with tapered edges and a self adhesive back. The roll is 44" long and weighs 13 grams. The weight of a pair of Dewey bar ends with steel bolts, and Chromed end plugs is 195 grams. Price in Catalog

The Dewey Too bar end set, has much in common with the Dewey bar ends. They have the same cinch tube, use the same cinch bolt, come with four of the same chrome end plugs and also comes with a 44" roll of the same grip tape. Though they use the same grip tubing material, the Dewey Too bar ends differ only in bend and length of the grip tubing section. The grip tubing section is 5 3/8 inches long, miter cut to fit the cinch tube and TIG welded to the cinch tube. The grip tube is welded at a 25 degree inward angle toward the front tire. 2 1/4 inches from the cinch tube, the grip tube begins a sloping upward bend of 35 degrees. The Dewey Too is, like the Dewey bar end, entirely Nickel plated. The weight of a pair of Dewey Too bar ends with steel bolts, and Chromed end plugs is 202 grams. Price in Catalog
