Wheels for Purpose
With a max loading of 130kgs, the Core 50-D HDs are aimed at more powerful riders. With an increased spoke count and 2-cross lacing for the front and 3-cross lacing for the rear, these have a higher max loading compared to the standard 50s but still have the same benefits when riding. The deep section rims utilise every millimetre of the U-shaped Aero profiles to cut through the air across a wide range of yaw angles; gliding effortlessly at speed. If you want to know more about wheel aerodynamics, and why we designed the Wide+ models, check out our Naturally NACA blog.
Coming in at only 1,580g, the Core 50-D HDs are exceptionally lightweight and pound-for-pound, feature amongst the best deep section wheels out there. Partnered with lightning fast Ratchet Drive hubs, these wheels respond FAST, offering unrivalled levels of performance.
The Wide 21mm internal profile gives you the option to fit wide tyres for increased stability when cornering, and increased speed due to improved rolling resistance - especially when ran as tubeless. With a centrelock disc as standard, you can ride with confidence knowing the stopping power is there when it's needed.

Bearings
You choose! Bearings are an essential component of wheels and it's important your bearings perform as you want them to.
Endurance Bearings: are fast & designed to stand the test of time, so you can ride as much as you want with confidence.
Race Bearings: But for those looking for every Watt gain, you may prefer super-fast Race bearings! *Please note: Race bearings are FAST, but they have non-contact seals which are less resistant to water.
Ceramic Bearings (Grade 3): If you're searching for ultimate levels of performance at a fraction of the cost, then Ceramic Bearings are your go to option. Offering an extended lifetime, lasting 3-5 times longer than regular steel bearings they also deliver a 5-9 watts energy saving which is huge!

Spokes and Nipples
- The Scribe 50-D HD wheels have been upgraded to the Pillar Wing 20 spoke. Following aerodynamic and laboratory testing, the Wing 20 offers increased aero benefits over all bladed spokes on the market with increased stiffness. At 4.3g each, and almost as light as Titanium, we can build you a super-lightweight wheelset that allows you to get up to speed fast with increased aero gains when at speed.
- High strength, Swedish Stainless Steel T302+ aero spoke (2.0mm – 1.2mm)
- Pillar Patented head technology offers increased strength at anchor point and reduces fatigue so your wheels stand the test of time.
- J-bend spokesÂ
- 24 hole front/28 hole rear
- For nipples, we use Brass Pillar Lock nipples. As the Core 50-D HDs are designed to be exceptionally tough, brass nipples have significantly improved fatigue resistance when compared with alloy, and they don't corrode, so you can ride them in wet, salty conditions without having to worry about them failing.
Lacing Pattern
- Front: disc side 2x, non-disc side 2x
- Rear: disc side 3x, drive side 3x
Additional items in the box
- Tubeless tape: pre-installed
- Tubeless valves
Weight limit: The upper combined weight limit (bike weight + rider weight + luggage) for these wheels is 130kg. If a rider is in excess of 105kg, we recommend regular wheel checks from an experienced bike mechanic.
