Straight-Pull PSR WING 21 2.2/2.1/1.3/2.0 BLADED BLACK 310mm Pack 20pcs No Nipples

Straight-Pull PSR PSR WING 21 2.2/2.1/1.3/2.0 BLADED BLACK.

The WING SPOKE was designed to outperform the current crop of high-end spokes that are found on today’s finest racing wheels. The WING is more than just another lightweight, bladed spoke. Inspired by the nose cone of an airplane, it offers the highest level of aerodynamic performance of any spoke on the market today. Wheel builders will also appreciate the ease of working with the WING. Its one-piece, butted design reduces potential weak spots, while its rigidity helps prevent twisting or breakage when tensioning. The WING will work well with any hub designed for 14g spokes. 

In the case of wheels with brake discs, the braking force is generated at the hub and transferred to the rim via the spokes. So basically from the inside to the outside of the wheel. As it rotates, the braking force is converted into a torque that is transmitted from the hub to the rim via the spokes. This is the reason why so many disc brake wheels, including wheels with aero rims, are equipped with round spokes. Because light aero spokes with a flattened middle section are too thin and too flexible to be able to absorb these torque loads sufficiently!

The Wing Spoke made of cold drawn T302 + stainless steel (Sweden steel) solves this problem in an elegant way, thanks to its elliptical shape it takes advantage of the flat, light and aerodynamically cheaper but weak aero spoke and the stronger but less aerodynamic and heavy classic round spoke. As a result, it has the diameter required for torque transmission and at the same time favorable and superior aerodynamic properties with low weight!

Pillar Racing Spoke has been a global leader in spoke development for over 30 years, and holds numerous patents on the technologies and products that have been developed over the years. With specialized manufacturing facilities in Taiwan that are closely linked to its own research and development facilities, Pillar Spoke is now the first choice for spokes and nipples of the most respected manufacturers in the bicycle industry, as the products meet the highest industry standards.

PLEASE NOTE:
It is important to make sure when ordering spokes that you make your choices carefully. Use a reputable spoke calculation program (or three) to work out the lengths, if you are unsure how to do this, then speak to a professional wheelbuilder before placing your order. If you are unsure which spokes are most suitable for your needs, contact us or speak to a professional wheelbuilder.

We can not refund or exchange spokes once they have been picked, packed and invoiced.
