Wheels for Purpose
The Core 3850s were designed to offer maximum Aero benefits while staying as lightweight as possible. Where the Core 38s are super fast accelerating with good Aero benefit; and the Core 50s fast accelerating with excellent Aero benefit, the 3850s are in that middle ground - offering a lightweight weight/ Aero alternative that will perform over every imaginable terrain.
Weighing only 1422g, Aero 3850s are exceptionally light in weight and pound-for-pound, feature amongst the best mixed depth wheels out there. Partnered with lightning fast Ratchet Drive hubs, these wheels respond FAST, offering unrivalled levels of performance.
The Wide 19mm 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. By using a Super High TG Resin for the Core 3850s, 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 when needed. The 26mm outer allows easy installation/ removal of wheels.

Product Details
Rims
- High filament (12K/18K) Japanese Toray T700/T800 carbon fibre. Unidirectional for strength with additional reinforcement at spoke holes. (spoke tested to 280 kgf [single spoke load])
- Scribe Carbon T:Tech used to strengthen rim walls, and rim bed - offering incredible long-term strength, even under high pressure
- High TG (Glass Transition) resin produces a lightweight, low void carbon which increases stiffness, and resistance to heat on braking track (great for hard braking on descents)
- Wide 19mm internal profile produces a great tyre profile for improved grip and stability
- 26mm outer rim width provides ample clearance for brake manufacturers
- 4-D precision drilled spoke holes - directs spokes exactly to hub anchor point
- Tubeless ready design will offer increased puncture resistance, faster-rolling wheels and improved weight (works with standard tube also)
- Tubeless tape fitted
- Ramped rim bed for easy tyre fitment
- Bead lock design for secure tyre binding, even at lower pressure
Hubs
- Scribe Exclusive Patented Ratchet Drive hub system
- Single Ratchet disc, and leaf spring offers incredible durability as there's only one moving part
- Heat treated stainless steel drive ring
- Fully CNC'd rounded design with 4-D precision drilled spoke holes
- Shimano (HG & HG+) /SRAM (PG) 8/9/10/11/12 speed compatible Anti-bite freehub body fitted - Campagnolo and XDR also available
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 3850 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
Quick Release (QR)
- Scribe Aero Super-light alloy QR
- Alloy pivoted cam plate for smooth action, but with strong locking bind
- Stainless steel springs for anti-rust (weather) protection
Additional items in the box
- Tubeless tape pre-installed
- Tubeless valves
- Brake pads, specifically formulated for rim carbon/resin matrix. (x4)
