    Will my DA Track Hubs + Mavic OP hold up to a Singlespeed Double Century??

    I just have to know if they are reliable for this.....will be doing a double on my SS next month...

    They will hold up just fine, unless the roads were made of speed bumps and massive potholes.

    Pick good tires so you will have a smooth ride.

    Also, be sure to post pictures or follow up of the double century!

    It doesn't matter to your bike if you ride your bike 10 miles a day for 20 days or 200 miles in one day.

    Sorry open pros have a manufacturers spec limit 115 miles per day, i think the DA hubs are rated at 240 though so those should be ok.

    I do have a question about loose bearing hubs. I know that sealed hubs haven't been around all that long and that people must have ridden in the rain before Phil debuted their hubs.

    Suppose that the streets were wet at the beginning of this century. How easy is it for water and grit to make their way to the bearing surfaces? Provided grit makes its way to the bearings, how long will it take to damage the bearing if you continue riding on it?

    The scientist in me suspects that the bearings are all made of much harder material than most road grit would be and some clean grease would take care of most anything. Is that right?

    Water by itself isn't a problem if you use good synthetic grease. Normally only extremely fine dirt or grit will find its way into the bearings on road hubs due to the close fitting shield or seal. The biggest threat is corrosive chemicals that might be dissolved into the water that comes off the pavement. When you get home after a wet ride, remove the wheels and turn the hub axles. If you can feel any roughness, then clean and repack the hubs. I have loose bearing hubs that are decades old and have seen tens of thousands of miles use in all kinds of conditions and the bearing races are still in perfect condition. I usually replace the balls every 5K miles.

    Thanks TT. One more question...and I don't mean to open a can of worms or anything with this.

    Dura-Ace or other high quality loose ball hubs [when properly adjusted] will turn more smoothly than a quality sealed hub, correct? Or is the difference completely negligible?

    thanks! I hear those 'seals' on the DA Hubs are pretty lousy.....hope it doesn't rain and I'll probable need to repack after the ride anyway.

    I believe so based on my experience, but don't have any scientific data to prove this. IME, sealed cartridge bearing hubs will have some drag from the seals, and since they cannot be adjusted, they need to strike a compromise between low rolling resistance and minimal play. Still, either way the overall quality of the hub / bearings is more important than the type of bearings, and in absolute terms the rolling resistance of hubs is negligible as compared to other drivetrain sources such as chain / sprockets and tires.

    Nothing to worry about. Used to put on 200+ miles a week with loose balls in this:



    And only repacked once every spring.

    Looseball, set right will outroll sealed. But this requires maintenance and fiddling. The difference is so negligible however.

    Except when using caged bearings. If you loose ball a caged setup like a coaster brake the results are impressive. Small to some, but a big improvement.

    DA hubs to me are not meant for inclement weather but will perform just fine as mentioned above.

    I'm happy to report that I successfully completed a Double Century last weekend (over 2 days) with my Single Speed. And yes, the DA track hubs rolled so smooth! now its probably time to service them!!

    Only if it rained. Loose ball run forever if dry.
