Wheels for Purpose
The Scribe Aero Wide+ 4250s were designed to be the ultimate, go-to Aero option for those riding over mix terrain where you are in/ out of the saddle. 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.
At only 1,442g, the Aero 4250s 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.

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. *there is no additional charge for bearing swap.
- Endurance bearings: LU/LB TPI sealed bearing designed to stand the test of time so you can ride as much as you want, with confidence your bearings will keep spinning smoothly
- Race bearings: Japanese EZO bearing - 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 Scribe Aero Wide+ 4250-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
- Front: disc side 1x, drive side Radial
- Rear: disc side 1x, drive side 2x
