How well should a cassette "spin"? Velocity rear hub.(5 posts)

How well should a cassette "spin"? Velocity rear hub.Eug

Just wondering. I got my new Velocity Fusion wheel - $110 from Nashbar for a 975 g (measured at post office, without skewer) semi-aero wheel.

I didn't take it apart but the rear wheel supposedly uses sealed bearings. Indeed, the wheel rolls fine if the cassette moves with the wheel (as would be when pedalling), but does not "glide" so well (as would be when not pedalling). In other words, the wheel doesn't spin as well as my other wheels when the cassette is held stationary.

One difference I've noticed is that the normal "click" is significantly louder and stronger with this new hub than my others.

I'm thinking it would not matter as long as I'm pedalling, but it would make a (slight) difference when not pedalling, ie. gliding. I'm just wondering if it's normal for this hub, and if many higher end hubs do this.

How good is a Velocity rear hub supposed to be anyway? Does anyone know the sizing of the Velocity hubs vs. Shimano hubs?

The freehub body needs to spin easily enough so that the rear derailleur can take up the chain slack while you are coasting. Try this. Lift up your rear wheel and spin it forward. If your cranks turn, that's bad.
Thx. Nowhere that bad... Anybody know specs of this hub BTW? nmEug

Hmmmm... My friend's Campy Proton seems almost as "tight"...Eug

I guess I won't worry about it.
Give it a few miles to break in.jw25

Especially for sealed bearing hubs, things need a little time and use to settle in. I'd be the hub uses 2 beaings in the body, and 2 in the freehub. Those two in the freehub are probably the source of the drag, but sealed bearing carts will loosen up with use.
Let us know how the hubs hold up - they're a great deal.
