Pillar Wing 21 J-Bend Bladed Aero Spokes – Black – 300mm, Pack of 20
SKU code: DTW-PRG-SJPW21K300Q20
Pillar’s Wing 21 is a bladed aero J-bend spoke — round 2.2mm at the elbow and thread, flattened to a 2.1mm-wide, 1.3mm-thin blade through the body for lower drag than a round-section spoke, aimed at road and gravel wheels.
Highlights
- Bladed aero profile: 2.2mm round ends, 2.1mm-wide blade, 1.3mm at its thinnest
- J-bend head for standard hub flanges
- Stainless steel, black finish
- 95° elbow bend, 9.0mm thread length
- Supplied without nipples
- Packed in bags of 4 or 20
Why bladed
Flattening the mid-section into a blade cuts the spoke’s frontal area without reducing its cross-sectional strength — the same principle as an aero road frame tube. Pillar keeps the elbow and thread round and full-gauge so the head and threaded joint aren’t weakened by the aero shaping.
Compatibility & fit
Spoke length is specific to the hub, rim and lacing pattern of the wheel it’s built into — there’s no generic right answer. The Tune Cycles workshop calculates the correct length for your build and laces the wheel in-house; because these spokes are supplied without nipples, pair them with nipples sized to this spoke’s gauge. A spoke cut or ordered to the wrong length can’t be corrected afterwards.
