Bar ends are usually not recommended for carbon handlebars, the reason is that when you grip the bars, it will push pressure and downward force deep within the resin and material of the carbon, which will result in deforming and cracking of the carbon handlebar, mostly these bar ends are recommended for stronger and firm material handlebars which are steel and aluminum bars. these bar ends also require recommended and normal rotating torque force if you are persistently installing them within the carbon handlebars, applying a large force would also break and crack the carbon handlebar of your bike.
Also, there are limited and recommended tool wrenches for tightening and clamping purposes of the carbo material bikes and these tools are expensive in their prices as compared to normal tools which are for aluminum and steel material bikes and bike parts. carbon material bike parts are also used and touched very carefully because the internal layers and material sued in these carbon handlebars do not warn you about cracking and breaking from any part and these will directly and suddenly break with a click of sound without alarming you about the breaking.
There are some riders who have a bad habit of putting all of their upper body weight on the bar ends of the handlebars on the trails during riding, in these cases also you are destroying your carbon bars with your hands by doing these tricks by gripping the bar ends of the carbon bars. also, the proper way of installing bar ends on the carbon handlebars is to keep the tensioning of the bar lower so that the contact and the joining point of the ar ends and handlebars do not remain tight and firm like the other bike parts are joined with each other more firmly, low tensioning is important because of the material difference of the handlebars.
Bar ends also depend on the specifications and compatibility of the carbon handlebars, there are a few brands of carbon bars that are eligible and are compatible with adjusting and connecting bar ends with them, but there are a few brands that are not compatible with the attachment of the bar ends, so when you are looking and observing to attach the bar ends with the carbon bars, always check the compatibility, durability, and specifications of the carbon bars for this setup. the best checking for the compatibility and durability of the carbon handlebar is that you can ask the manufacturer or local experienced mechanic regarding the carbon bars and ask them about the warranty and durability of the carbon bars for the attachment of the bar ends.
