There was no burr on the inside, and the installation was smooth. After replacement, I used it for about 6 months. I use it for about 1 hour every day, 6 days a week on commuting. Surface stickiness, which is common in cheap goods, has not yet occurred. (It may be because it is winter.) The only thing that is worrisome is that the pattern on the surface to keep the grip is frayed into a slippery shape. Although there is no problem in use, the appearance has become less satisfactory.
Since the spreading portion of the tip reduces the load of the palm, it is considerably better than the one of ordinary shape when riding for a long time. Although it does not have a Gagnaggia to say that it contains a gel, is it still absorbing the subtle shape of the palm? Recommended for bicycles that are tilted forward with flat bar handles.
It is not so soft as you imagine listening to the built-in gel. The gray part is harder than about 1 mm dented by the finger tips strongly, the black part is harder than that, it is hard enough to feel the dent by pushing with the nail. So if you do not set the angle to hit the palm on average, the part you hit strongly will hurt. I prefer a soft one myself, but I have a firm feeling, this is not bad with this. Since the installation is a type that tightens both ends, there is nothing troubling at plugging in and pulling out at all. Three millimeters and 2.5 millimeters Allen key is required for screws at two inner metal rings and one at the lower side of the handle end. If you hit the end bar with your thumb, you will want to cut the handle shorter a bit because it is slightly open to the outside, but this grip itself is somewhat longer and the installation space for the steering wheel is less troubling. Strangely, although we just protruded a few centimeters ahead, the handling in a narrow place worsened, and I often hook the end bar. Well it is a problem of accustomed. I do not know well that durability is just beginning to use, but I think that it is better than a soft one. It is cheap to have an end bar, it seems to be fearless in one piece design, cost performance is high. I wish it was better to cut the length and adjust it.
