IB13: Zipp Makes Rear Hubs Stiffer For Cavendish, And You

2014 Zipp rear hub updates make them stiffer for Mark Cavendish

For 2014 models, all of Zipp’s rim brake wheels -the 202 tubular and the entire Firecrest range- get completely redesigned rear hubs.

The 188 V9 hub was developed with and for Mark Cavendish, who tends to put a lot of stress on equipment. Larger, thicker flanges and larger Swiss stainless steel bearings in the hub shell (same 17mm axle) add up to a 20% laterally stiffer and 140% torsionally stiffer wheel. That means there’s virtually no effort lost to wind up or flex during massive sprinting efforts.

Spoke counts have bumped to 18/24 across the range, too. They call it a “virtual 3-cross” lacing because if you extended the spokes they’d cross again – but really it’s a 2-cross pattern.

All in, there’s a gain of about 30g, but most of that’s at the hub. Front hub and rear disc brake (303) hub don’t change.

Rims get new diecut logo decals that are a bit sharper looking with a thinner, lighter material.

They’re also experimenting with printed labels (like Reynolds), but for now the amazing graphics are limited to wheels used for coffee tables. Want!

I don’t get it… what are “rim brakes”?

I love marketing, lol.

you are right Speedy, if you took a standard 24h hub with the same flange diameter and laced it 2x i’m sure you would end up with the same spoke angle. I love when new advancements in wheel tech are just return to us to what classic wheelbuilders have known all along.
Gripping aside, I appreciate that Zipp is now making a wheel that i would be more inclined to buy, though id be more likely to build up there rims to my own spec.

How do thicker hub flanges make the wheel 20% stiffer? That is pure bs. They would have to widen the bracing angles to make the wheel stiffer, and with an 11sp freehub body my guess is these latest hubs have a narrower flange spacing than older 10sp hubs. How come no one questions claims like this and demands the calcs behind them? And since when is windup a problem that needs “improving”? Even on mountain bike wheels with crazy amounts of forces near the hub (disc brakes) it isn’t an issue.
