I love that they make it easy for you to get the parts you need to service these hubs! Bearings worked great.
Everything was perfect!
Couldn't find the front hub end caps around here, but the good thing is that Chromag can make international shipments. Thaks for that 👍
Caps worked
Good to know!!
Wicked service!
