First the bottom bracket falls off. Next the top falls off. I have these one week and 2 out of 4 are broken. They are not worth the hassle to return. I am begining to have doubts about the quality of some of the products Sierra carries.
Do not buy. Not sure why they were given 4 stars. Maybe this is a bad batch. But the construction was poor even if they didn't come apart.
