Bought some new Scribe wheels..and they're NOT noisy...????

Sorry to gatecrash; I don't post here often.

Just purchased some Scribe Pace alloys for winter, so the carbons can go in hibernation.

To my surprise (and against what I'd read), they're not noisy in freewheel at all. Just a light buzz. Far, far quieter than the three sets of Hunts I've got (now very worn alloys, carbons and the set on the cyclocross). And no different than a typical mountain bike. So plus there.

Are Scribe now using a thicker grease? (nb, they did say, due to a shipping delay, I'd get a free update: "The new model comes with updated graphics, Sapim CX-Ray spokes and a refined hub design" (whatever that all means).

But, I did note that, on the stand, the front wheel, running a simple spin test, doesn't spin as freely as any of the Hunts, or, for that matter, the original wheel my bike came with. Those all spin for ages, with the valve eventually settling at 6o'clock. I queried this with Scribe:

"The wheels are brand new and the hubs are equipped with a very high quality, lightly lubricated sealed bearing. Bearing efficiency can not be measured or judged by a simple spin test, a bearing needs to be loaded to perform. In most instances, a cheap or potentially worn-out bearing will spin longer in the stand but under load is inefficient.
I'm sorry your initial thoughts are disappointment but I'm confident there is nothing wrong with your wheels and as the wheels are used, the grease will disperse, the bearings will bed in and everything will free up."

I accept that grease will disperse (although just done a 50ml, no change), but I wouldn't accept that, chemically, a modern grease would break down in any way.

Any thoughts? Like everyone else, I don't want to be wasting watts.

  • I wouldn't worry about it. Spin down tests on new wheels aren't indicative of much, I agree with the answer you had from the manufacturer. Overcoming bearing drag is something that gets lost in the noise of any real world test as it's less than 1W. If you are using them as winter wheels I doubt bearing drag will matter. Presumably you'll want either a fat, wide anti-puncture layer tubeless tyre or a fat, wide anti-puncture layer, butyl tubed tyre, which will be the main drag of xxW on your rolling resistance (vs a fast summer tyre).
