Wheelbuild spoke selection
Postby familyguy » Tue Jun 04, 2013 1:50 pm
I know the two major players as far as quality spokes are Wheelsmith and DT, but does anyone know about these Pillar guys?

I would be willing to up-budget to DT's, but it'd take another few weeks before I could even think about ordering anything.
Pro? Con?

Pillar as far as I know are based in Taiwan and their spokes appear on a lot of wheels that are assembled there.
I don't see any reason to think that that these will be any different to eg. DT Alpine III, and Sapim Force.
Despite the marketing, the wire used to make stainless steel spokes is almost identical.
Triple butted spokes are generally a good thing, they are a tight fit in the holes so it is best to lace the wheels with the 'heads-in' spokes inserted last to give you the most wiggle room.
Cheers,Sheldon Brown wrote:Triple-butted spokes, such as the DT Alpine III, are the best choice when durability and reliability is the primary aim, as with tandems and bicycles for loaded touring. They share the advantages of single-butted and double-butted spokes. The DT Alpine III, for instance, is 2.34 mm (13 gauge) at the head, 1.8 mm (15 gauge) in the middle, and 2.0 mm (14 gauge) at the threaded end.
Single- and triple-butted spokes solve one of the great problems of wheel design: Since spokes use rolled, not cut threads, the outside diameter of the threads is larger than the base diameter of the spoke wire. Since the holes in the hub flanges must be large enough for the threads to fit through, the holes, in turn, are larger than the wire requires. This is undesirable, because a tight match between the spoke diameter at the elbow and the diameter of the flange hole is crucial to resisting fatigue-related breakage.
Since single- and triple-butted spokes are thicker at the head end than at the thread end, they may be used with hubs that have holes just large enough to pass the thick wire at the head end.

I might de-lace the front and measure the spoke holes a little more accurately before I pull the trigger on those ones. I dont want to order 72 of them and find they wont fit through the flange. Nothing a little judicial filing wont fix, but I'd rather not if I could avoid it.

If someone is selling good pre-built wheels and they don't advertise the brand of spokes then it is a fairly safe bet that they are Pillar.familyguy wrote:Yeah, I forgot Sapim. I've not noticed the Pillar name, apart from the ones I'm looking at just now: http://www.pillarspoke.com/p02-4_psr_triple_butted.htm#" onclick="window.open(this.href);return false; (model PSR TB 2018).

It might be easier to measure the thread width of your spokes, since you know they fit through. I'd be astounded if the holes weren't at least 2.3mm.

as Mr. hang glider pointed out the spoke holes are usually a little bigger especially if used. And even if not it's not too tricky to open them up a little bit. Below is a pic of some NOS hubs from the 50's that I drilled and chamfered for modern spoke gauge sizes. If your hubs show a lot of spoke pull might be a good idea to do similar just to get them round and even again.familyguy wrote: I dont want to order 72 of them and find they wont fit through the flange.

I have hardly had any DT or Mach 1 spokes break before and are pretty much the strongest spokes. Lots of people call Sapim spokes snapim as that's pritty much what they'll do after a while. I'd stick with DT or Mach 1 for strength.

I still tend to use the latter two simply due to cost, have never had any performance issues, durability has always been equal between the three, but they do have crappier threads and cut off.

Brick Lane have replied to my query regarding radial fronts in the affirmative. May look at a radial head in lace on that one now. Going onto a Ukai 25c box section, eyeletted. Main concern is the rim, especially given it will be doing some braking.

BTW, I'm using DT Swiss Revolutions for my upcoming Ambrosio build (whenever my irish hubs arrive)...

Key spoke and initial trailing spokes (after testing and shifting the four spokes I'd placed four holes over to get the valve hole over the makers name):
And....done, except the last two spokes:
And proof I got the valve hole in the right spot:

Neat solution. I didn't want to get too advanced beyond Wheels 101 just yet. Radial front should be easier.Duck! wrote:Quick tip for when you get to doing the front. First spoke, centre the hub logo & lace the spoke to the immediate left of the valve hole. Next spoke directly opposite, then flip the wheel over & lace in an opposing pair at right angles to the first pair. That will stabilise the hub, then you can just go around & lace the rest in.

Roger Musson shows a simple technique for aligning the valve hole with the hub logo based on your cross pattern. Sadly, he tells you this at the end of the book, not at the start where it is useful.familyguy wrote:Neat solution. I didn't want to get too advanced beyond Wheels 101 just yet.

I am waiting for some spare time to build up my new wheels.
When I order spokes I always get extra of each length, so for a 36 spoke wheel I buy 4 extra spokes (2 of each length).
I recently threw the chain into my rear wheel and destroyed 9 spokes, so I was lucky to have the spokes from my old wheels, as I did not have enough new spares.
I have learned that as a commuter I need to have all consumables/breakables as spare parts on hand, including wheels. As I use up my spares, I order new stock so that I can keep the bike on the road all the time.

Looks like a good pair of wheels to me.

Noticed last night the spoke angle coming out of the rim seemed a little sharp. Closer inspection (with verniers) reveals the eyelets are offset by less than 1mm to either side. Naturally I've laced them to the opposite side, haven't I...
Problem?

Another good guide is when you're looking at the wheel side on, with the valve hole at 12 o'clock, the spoke immediately to the left of the valve will be on the side of the wheel towards you. Virtually every rim with staggered drilling will be set this way.
