Wheel Building!

Got my Hope Hoops re spoked last week by the local bike shop, at close inspection I have noticed that they have'nt crossed the spokes. Is this correct?

Hubs: Hope Pro 3 Straight Pull

Rims: Crest ZTR

 

Thanks

Is thison all wheels?

 

Does it look like the pic below. Not sure if this is OK on MTB wheels and I have only really seen it on road bike front wheels. If it looks like the pic below it is called Radially Spoked.

Found this in Wikipeadia - http://en.wikipedia.org/wiki/Bicycle_wheel#Lacing , read in "lacing"

 

Interesting read, it may give you the answers you need:-

 

"Wheels that are not required to transfer any significant amount of torque from the hub to the rim are often laced radially. Here, the spokes leave the hub at perpendicular to the axle and go straight to the rim, without crossing any other spokes - e.g., "cross-0". This lacing pattern can not transfer torque as efficiently as tangential lacing. Thus it is generally preferred to build a crossed-spoke wheel where braking and drive forces are present. Hubs that have previously been laced in any other pattern should not be used for radial lacing, as the pits and dents created by the spokes can be the weak points along which the hub flange may break. This is not always the case: for example if the hub used has harder, steel flanges like those on a vintage bicycle."

Huh, isn't it physically impossible to radially lace a wheel with straight pull hubs?

Hubs made for straight-pull spokes generally have a flange configuration that doesn't allow the builder to play around with the crossing and lacing. In other words, the hub dictates what crossing and lacing you apply.

 

However, I think you are confusing crossing and interleaving.

 

Crossing refers to number of other spokes a given spoke crosses on its way to the hub.

 

Interleaving refers to the over/under path at the crossing. If it is interleaved, this means the spokes at the contact makes contact and generally change path a couple of degrees.

 

This means that a bike shop, no matter how hard it tries, actually cannot screw up the lacing on straight-pull hubs.

 

IIRC, Hope PRO III hubs are like that.
