Bar ends originate from the early days of mountain biking and are usually mounted at the end of the handlebar.
A good idea from an ergonomic point of view. In the course of time, when straight handlebars became less popular and raised handlebars more, the bar ends disappeared again. Now that handlebars have become flatter and much wider again, bar ends make sense again. However, these bar ends are mounted inside, hence the name Inner bar ends - with the small contradiction in itself. Inner bar ends are a new, innovative evolution of the good old barends from the early days of mountain biking, but with an unprecedented safety aspect. Despite the changed grip position, the brake levers are permanently within reach.
The inner bar ends don't weigh much and are no bother, just try them out. The inner bar ends almost always fit. They are mounted directly after the handle. Since almost all brake levers are so long that you can and should push them inwards for better braking performance, there is almost always enough space between the handle and the brake or gearshift. The inner bar ends have no fixed area of application. They are primarily suitable for the mountain bike: mountain bike race, cross country, marathon, trail bike, tours, all mountain, up to the enduro, to make the liaison stages easier. But also on normal handlebars of trekking bikes and even on the city bike, bar ends offer an optimal possibility to change the grip position.
