Hallo forum,

Simple question, I hope:

I normally use 32-spoke classis wheels with Ultegra hubs, Sapim "Race" spokes and Mavic Open Pro rims. I use these wheels with no problems at all despite my weight of 102 kg. I ride at speed but I am no racer and I don’t do races or competition.

Now for my question:

Would the following set be just as strong or stronger: 28-spoke wheels with Dura-Ace hubs, Sapim "Strong" spokes and Corima Aero carbon rims.

I choose Sapim "Strong" instead of "Race" spokes because of their intended use for trekking.

“Race” spokes test results:
Fatigue test / wheel revolutions : 980.000
Strength on middle section: 1350N/mm²

”Strong” spokes test results:
Fatigue test / wheel revolutions : 1.600.000
Strength on middle section : 1400N/mm²

Hence my choice for Sapim “Strong” spokes for the new wheels: lesser but stronger spokes. Does this make sense?

Thanks in advance for any advise.

honestly I must admit that I do not know the answer.

I think it depends on the stiffnes of the rim and how good your wheel will be laced.
The stiffer the rim the better it will spread an impact on several spokes.

The open pro for example is not that stiff compared to a cpx 33.

Hi,
I think your classic wheelset is better because the Mavic Open Pro has
double eyelets which allows high spoke tension. The corima has none or
at least single eyelets,i assume?!

I contacted Sapim and git a reply today. The "Strong" spokes are probably to thick for Dara-Ace hubs but they claim "Race" spokes will also build a strong enough 28-spoke Dura-Ace/Corima wheel with my weight.

Hi,

i would say the more spokes the better it is! But if you don't race the wheelset too often or use it only for races... i would put Sapim CX Ray in it. But don't use Aluminum Nipples!!! Take classic ones for stiffness and durability. The hole thing will also last longer!

MFG
