Will rotating bearing direction extend their life?

[veggieburger]

In other words, let's say for example that I have a front wheel that I have used for 5000 miles. Will I get any additional life out of my bearings by flipping the wheel and having the bearings roll in the opposite direction that they are used to?

The things you think about when you stare at your front wheel for a couple of hours.

[Black Dog]

No difference.

[54ny77]

only if you unwrap your bars and re-wrap them in the opposite direction, since bearing rotational wear is directly correlated with the downward pressure applied at the bars, as measured by a turbo encapsulator.

[Cicli]

Yes,
You have to ride uphill going north to make any difference though.

Yes, I have done this. I also find that swapping handlebar end caps makes them last twice as long, and inside out bib shorts grants an extra 3 months to chamois life.

I'm all about the hacks.

Yes, I get double the life out of my bearings by alternating between riding forwards and backwards!

a quick search on the internets, thanks Al Gore, it is all over the map,

nothing on rotation just cleaning and lube

but the range of life seems go from 10k- 50k miles

but if you uses Ceramic, please do not beat this dead horse
and run rpms similar to an prop plane you might wear them out

For $31 each you could be on the safe side
now at 25000 miles the wear cost would be $0.00124 per mile:eek:

FWIW I have a set of 303's with just under 31k miles in 3.75 season, not a peep out of them, I think I will have them cleaned this winter

personally I would just ride them into the ground

as you can see it is Friday Morning dead in the office, tired of hearing about Irma and heading out to ride the rest of the day

You do realize that if you apply chamois cream to your helmet, it extends your shoe cleat wear, don't you?

Yes, I have done this. I also find that swapping handlebar end caps makes them last twice as long, and inside out bib shorts grants an extra 3 months to chamois life.

If you move to Australia all your ruined bearings get a second life (or from Australia to the northern hemisphere)

because you are riding upside down?:bike:

[oldpotatoe]

Yes but only north of the equator, change it back if you ride in Australia:eek::)

I heard about this one. Very valuable.

In addition, grocery bags inside of water bottles not only keep your drinks colder for an additional 2 minutes, but they also extend the life of your water bottles.

Sometimes I steal ketchup packets and eat them like Clif shots. Money saved, sugar/salt absorbed...it's a win-win.

You must ride the velodromes in the southern hemisphere clockwise.

[donevwil]

To maximize the benefit you should also re-install the bearings upside down and must, at the same time, do the same with the chain. Forgetting this step will likely cause a high amplitude, asymmetric resonance that will undoubtedly lead to front end shimmy.

The things you think about when you stare at your front wheel for a couple of hours.Without any comedy routine, no. You'll do more damage to the bearings removing and reinstalling them each time. Bearing pullers aren't exactly gentle on a bearing that has a proper tight fit.

since bearing rotational wear is directly correlated with the downward pressure applied at the bars, as measured by a turbo encapsulator.

I might recommend a more modern Rockwell Automatic retro-encabulator.

The only new principle involved is that instead of power being generated by the relative motion of conductors and fluxes, it's produced by the modial interaction of magnetoreluctants and capacitive deractants.

Automatically synchronizes cardinal gram-meters.

[choke]

Forget the bearings, what you need is an oscillation overthruster....it will take your riding to a new dimension.

Kidding aside...I was thinking that if the front wheel was flipped, the bearings that may have been ground down somewhat from rolling in a particular direction would then be given some new life, similar to rotation the tires on your car.

I was running on 5 hrs sleep and pedalling when this thought hit me. I realize it has very little chance of being a practical application...or actually making any difference at all.

[ergott]

Nope. You would be committing a cardinal sin flipping wheel because the labels would be facing the wrong way.

Bunch of a**holes here. I'm still waiting for the answer. Life depends on it.

[cmbicycles]

Rotate the axles 90 degrees every 25 miles, and replace the grease with polishing compound. Then after 100 miles clean out the polishing compound and add fresh grease. It's like instant ceramic bearings, they will spin forever.
