Internal/wedge clamp aluminum bar ends for ATB/Mountain Bike/flat bar handlebar. 5 inches/13 cm long.
Rather than clamping OVER the handlebar these bar ends use a wedge or expander bolt like stems for threaded headsets.
These bar ends are the larger internal diameter intended for thinner wall handlebars with an internal diameter of 18+ mm.
(I also have the small I D bar ends for handlebars with an I D of 15 to 18 mm. Bring your bike/handlebar and we'll confirm which size you need.)
