Remember to get the correct
quantity! A set of 4 wheels will require an 8-pack of bearings... Set of
8 wheels with require a 16-pack of bearings or two 8-packs!
We could charge you extra for a shinny cardboard packaging and a colored
shield with some arbitrary name inscribed on them. You should only pay
for what you need, the bearings themselves, the most important part.
Dual metal shields (sometimes they will be rubberized shields) help keep
dirt and grime out, while helping keep lubrication in. They may come
with the words Titen, USD, Undercover, etc stamped into the shields. If
you get a really small pen you can write whatever you like on them.
Bottom line, decent bearings for a cheap price. Hirt nestles each set
into a random plastic bag or tube and hand writes the abec rating on
each one.
