Nearly all MTB/upright handlebars are 22.2mm at the grip end.What part of the handlebar diameter do you measure if your replacing them, is it the larger diameter area by the stem or the narrower section near brake leavers / grips etc
his handlebar (Sport CD) is made by Promax, flat bar, 25.4mm in the middle. The adjustable stem clamp is also Promax.If you want them to fit your existing stem, you have to check them in the middle. Contrary to what Trex says, many MTB handlebars are often 28mm (1 1/8") in the middle. All handlebars are 22mm at the ends
