The only drawback, which has this bell, is their relatively smaller diameter at the fastening. Since many MTB handlebars are slightly thicker than most handlebars, the bell can not be perfectly applied in some bicycles. On my bike I had to push quite far to the outside, so they ran to fasten well the bell.
Overall, a solid bell at a good price - but who has a very thick handlebar on his bike should be possibly look for another model.
