Wheels for Purpose
The Core 42s were designed to perform in every imaginable condition. These wheels will climb hard, cruise at speed, and allow you to get up to speed fast when the power goes on. The wider profile gives you the option to have increased Aero benefits by simply changing tyres! If you want to know more about wheel aerodynamics, and why we designed the Wide+ models, check out our Naturally NACA blog.
Weighing only 1,422g, the Core 42s are exceptionally lightweight and pound-for-pound, feature amongst the best 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 Centre lock 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 Aero Wide+ 42-D 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.
- Straight-pull for increased torsional strength
- 21 hole front/24 hole rear
- For nipples, we use Pillar Patented TG Lock square head so the nipples are locked into place
Lacing Pattern
- Front: disc side 1x, drive side Radial
- Rear: disc side 1x, drive side 2x
