29er wheelset spoke Choice.

[Beerboy]

I have just bought a set of Stans Crests with American Classic Hubs.

 

the bike shop built up the wheels using DT Comp Spokes (2-1.8-2) on the front wheel

The rear drive side is also comps with the non drive using Revolution (2-1.5-2)

 

Any comments on this build, i thought that the front wheel would have been built with Revolutions as well?

 

They also mixed DT and Sapim spokes on the front wheel, i assume that these spokes are very similar so i guess it makes very little difference.

Everybody will be interested to know what the set weighed

 

and who built the wheels?

 

I dont have a comment on the choice of spokes, except that it seems they have weight weenie tendancies.

How much do you weigh?

I would not put DT Swiss Rev on 29er wheels. I have DT Swiss Competition on. LBS is currently building a wheelset for my brother with Pillar spokes, DT Swiss brings it in, lighter than Competition, but aparently its flippen strong and can be tightend much more than Competitions. Look into them.

Pillar is my choice as well...

It's a bit of a mongrel build. It seems as if the wheelbuilder didn't have all the required lengths in stock and just used what he had. Had the choice of spoke been made rationally, the front wheel would have had Revolutions all round and the back wheel a mix of Revos and Comps. However, there is nothing wrong with putting revos all round if the rider is light.

 

Revos are far more durable than competitions due to some extra cold forging and good science. Durability and strength are often confused, as we see in this thread. The strength of a spoke is generally measured in the tensile dimension, in other words, how big a weight can you hang from the spoke before it breaks. In this mode. All spokes - good and bad, are far stronger than we require.

 

However, durability comes in when that same spoke with that same load, has to turn many millions of times and still not break from metal fatigue. That is durability.

 

So, Competition spokes are stronger than Revolution spokes bu so what. Revo's are more durable by a long margin.

 

The downside of Revos is that they're quite thin and therefore the wheel flexes a lot if the rider is heavy. The large the wheel, the larger the deflections. On disc brake wheels it doesn't matter if the wheel flexes - you can't feel it. However, someone riding behind you can see it.

 

I like to suggest a weight cut-off limit for Revo's at 80kgs. This figure is of course arbritary and depends on the stiffness of the rim. Crests are too light for a heavy person if Revo's are used.

 

As for Pillar. Pillar is a Taiwanese brand with no better (or worse) credentials than the other big-brand spoke manufactures namely Sapim (Belgium), Wheelsmith (USA) and DT Swiss (Switserland). All these spoke manufacuters use 18/8 stainless steel that's been vacuum degassed and all of them are equally strong. I use "strong" reservedly here. Only Sapim and PIllar publish cyclical durability but not in the same units. Therefore comparisons are invalid.

 

Having said all that, a good wheelbuilder will extract the maximum durability from the spokes, no matter what brand, by stress relieving. This is the secret of a good wheel and since it requires some understanding of metal fatigue, I'm afraid it remains a secret understood by few.

Thanks Johan

 

i'll probably rebuild the front with Revos later.

 

@Splat : 731g Front , 824g Rear That includes Tape and Valves. Brass nipples were used.

just out of interest, where did you get the American Classic hubs? which ones are they, and how much$$?

Roughly R300 cheaper than Hope Pro 2 Evos
