* Please note that in general, bar end shifters can be used mainly for drop handles with a bar diameter of 23.8 mm, and cannot be attached to flat bars with a bar diameter of 22.2 mm. However, since the inner diameter of the handle that can be installed is 19 -22 mm, it may be possible to install it on some promenade mustache type handles. Make sure the inner diameter is 19-22 mm.
