Don't pay silly prices for bearings for your pride and joy. They are often poor quality even at a high price bracket.
Discounts can me made if buying multiple bearings.


Never over tighten your headset bolt. if the headset is loose it means something is bottoming out.
Make sure there is a 5mm raise on the space or stem for the top cap to do its job!
Overtightening will crush the bearings and will cause them to feel rough very quickly.
