Breaking Strength

Spoke Tension

According above datas and our client feedback, we find the PBA 1420 spokes are strong enough, and the weight is lightest, comparing to PBA 1425 spokes and PBA 1422 spokes. So we choose PBA 1420 spokes for wheelsets currently.

Pillar psr x-tra 1420 spoke VS CN Aero424 spoke

We have do some research on pillar 1420 spokes and CN 424 spoke these weeks. Both pillar 1420 spokes and CN 424 spokes are light, around 4.0g/pcs to 4.3g/pcs. But CN 424 spokes are much thinner and much cheaper（the price is only half of pillar 1420 spoke) , we have got some to test and if the spokes are ok, we can use it and make the wheelset price lower for customers. But while we build one wheelset, two pieces CN 424 spokes are broken.

So, we decide not to use CN 424 spokes, still use pillar 1420 spokes. For pillar psr-xtra 1420 spokes,there are detail testing data on Pillar Spoke website like breaking strength, spoke tension breaking strength & spoke tension. But for CN 424 spokes, the data is not clear on CN Spoke website.

Pillar PSR X-TRA 1420 spokes are really better than CN Aero424 spokes.

We will keep on looking for better spokes with good price for customers,like DT super comp and Sapim CX-ray spokes. Sapim spokes are much expensive than pillar spokes, and we will try to contact the agent to get better price.
