Wheels for Purpose
The Core 38 HDs are a Heavy Duty version aimed at Powerful riders. The Core 38s were designed to be the ultimate fast accelerating/super-lightweight option for those chasing aero benefits on flats and a fast responding wheel set on hills. With 38mm hoops on either end, these wheels are an excellent all-rounder.
Hitting the scales at only 1,410g, the Core 38 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 19mm internal profile lets you fit wide tyres for increased stability when cornering, and increased speed due to improved rolling resistance - especially when ran as tubeless. By using a Super High TG Resin for the Core 38 HDs, you will be able to brake hard (especially on descents) as the braking track can withstand up to 240 degree Celsius! Partnered with our own braking compound, you'll be able to ride with confidence knowing you can scrub speed as needed.

You choose! Bearings are an essential component of wheels and it's important your bearings perform as you want them to. All of our wheels come with a fast Endurance bearing as standard but we also offer a Race bearing for those racing or riding in drier weather. If you would prefer Race bearings, please tell us in the notes section when purchasing and your wheels will arrive with this standard.
- Endurance bearings: these bearings are fast and designed to stand the test of time, so you can ride as much as you want with confidence
- Race bearings: incredibly fast, sealed, non-contact bearings. Spin up effortlessly and allow you to glide at speed *not recommended for long periods of wet riding."
Spokes and Nipples
- The Core 38 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.
- Straight-pull for increased torsional strength
- 21 hole front/24 hole rear
- For nipples, we use Brass Pillar Lock nipples. As the Core 38HDs 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.
