one of the bearings started snagging you can feel it while peddling. this happened 2 days after installing with a proper tool and plenty of grease. it feels like a defect in one of the ball bearing's but because the part is used i cannot return it.

had to use a headset/bb installer to press in the bearings into the installed cups. bearings seemed to be too big once the cups are on the bike. bike is a 1999 gt vertigo bmx

When I received the item i noticed all the pieces just bouncing around padded amazon package. Inside was the package the item should of been in. It was cut open and empty. I noticed small nicks on the bearing caps where it looked like someone already try to instal it on another bike. If i wasn't in need of the parts I would of sent back but needed it and once its installed its hard to see the marks. Bearings are not very smooth but will do for now. I will buy different item on next build.

I used this to swap out a set of old one-piece cranks for a modern 3-piece set on a 1999's Haro for my son. Worked perfectly. Quality seems good and they provided everything I needed for the conversion. Had the project completed in about 20 min. A worthwhile upgrade.

But over all 5 stars.
