I have a Giant Cypress that I bought used two year ago. I believe the bike was two year old at that time and didn’t appear to have been ridden a great deal. I have rode the bike 4,600 miles, all paved rural roads. I have changed a number of spokes and have kept the chain cleaned and oiled (every 300 – 400 miles) and keep the derailleurs oiled and cleaned. That’s about all of the maintenance I’ve done other than brake pads and cables. Sunday while changing a spoke I was spinning the back wheel while holding the axel in each hand. The wheel turned easy enough but felt a little rough. I plan to take the hubs off and check the bearings and add grease (front and back). I’m going to need to order a few tools and parts. My questions:
Does anyone know what size hub wrench the front and back will take?
Are the bearings in the hub loose or in a race?
If loose, does anyone know how many and what size for each wheel?
Anything else I should order and plan to replace while I’m at it?
Any other advice or suggestions greatly appreciated. Thanks.

The cone wrenches are usually 13mm for the front and 15mm for the rear, and use a small adjustable on the outer lock nut.

As for the rest, no idea - take it apart and you'll find out!
