servicing wheels

Thats the wheel I have Formula/DBM-1 Double wall/Stainless. They equipped my fairly new Devinci St-Tropez hybrid. I wonder how often I should service the wheels bearings, Yearly ? twice a year ? I am not really riding long distance but I ride a little everyday. 6 to 10 miles I have 650 miles on my bike now ridden mainly on unpaved trail and asphalt .

It is hard to do ? . special tool needed ?

Thanks guys !!

I overhaul the bearings on my bikes every 2500 to 3000 miles. There is good info here. http://www.parktool.com/blog/repair-...es/hub-service

I'm pretty sure the Formula hubs on your bike are low-end pressed-bearing hubs and not serviceable. Basically, once the bearings are worn out, throw away the wheel and buy a better-quality replacement with serviceable-bearing hub, such as the many Shimano cup and cone bearing hubs. That's what I did on my Giant Yukon; the Formula rear hub failed after about 1500 miles.

WTF?

What "pressed bearing hubs" aren't serviceable? I highly doubt any hubs are going to be cartridge bearing on a $600 MSRP bike, and even if they were they are *easily* serviceable. If they are not then they are cup and cone, and also easily serviceable.

Sorry, op, I made a pretty bad hash of trying to reconstruct what I was told about my Formula OEM hubs. I was basically told they couldn't be overhauled/rebuilt, and I couldn't find any diagrams or photos of the hub design, so I somehow came up with the idea that they were permanent pressed-in bearings of some sort.

Looking now, I find these threads on the forums here (in which you figure prominently, operator):

Shimano hubs are not serviceable in the sense that one could replace the bearing cups when they are worn out but thankfully, Shimano makes high quality hubs and with regular maintainence these will deliver tens of thousands of kilometers of service.

Campagnolo hubs have replaceable cups so can be rebuilt when the cups are worn and the quality is so good that these will probably outlast any Shimano offering but you cannot beat Shimano on price and bang for the buck.

Cartridge bearing hubs have an advantage in that they are very long lasting and might go 30,000 + km before they need service and when service is needed replacing the cartridge bearing is usually quite easy.

How often you service your wheel bearings is a function of mileage, the conditions you ride in, and quality of the hubs.
