Elilee Carbon Spider

The missing piece for your ultimate build.

The Elilee Carbon Spider is the gateway to true drivetrain customisation. Designed for Elilee's award‑winning X‑series carbon cranksets (X310, X320, X260, X‑Novanta), this spider allows you to mount standard 4‑bolt 110mm BCD chainrings – including Shimano Dura‑Ace and Ultegra – onto your Elilee crankarms.

Why choose the Elilee Carbon Spider?

• 📊 Significant Weight Reduction: Save ∼30–50% of weight compared to aluminium spiders, helping you build an ultra‑light race machine.

• ⚙️ Standard Chainring Compatibility: The 4‑arm 110mm BCD design fits popular chainrings from Shimano (Dura‑Ace, Ultegra) and other 4‑bolt road rings – no more searching for hard‑to‑find direct‑mount options.

• 🔧 Easton Cinch Interface: The spider uses the proven Easton Cinch spline (16 teeth), ensuring a secure, creak‑free fit with all Elilee cranks.

• 🏆 World‑Tour Tested: Elilee components are used at the highest level, including a 2026 partnership with the Bahrain Victorious WorldTour team.

• 🛡️ Forged Carbon Construction: Built via carbon forging technology for high density, consistent strength, and a sleek stealth appearance.

Compatibility

✅ Compatible cranksets:

• Elilee X310 (all spindle options)

• Elilee X320 / XXE

• Elilee X260 / X‑Novanta

• Any other crank using the Easton Cinch interface (e.g. Easton EC90)

✅ Compatible chainrings:

• Shimano Dura‑Ace (R9100, R9200 series)

• Shimano Ultegra (R8000, R8100 series)

• Other aftermarket 4‑bolt 110mm BCD road chainrings

⚠️ Note: For best shifting performance, use genuine Shimano chainrings. User reports indicate Elilee spiders work well with Shimano rings, though a small number of riders note that shifting may not be "100% smooth" compared to a native Shimano spider.

Need a power meter?
The Cinch interface allows you to install a spider‑based power meter – simply replace the standard spider with a compatible unit from:

• Sigeyi AXO / AXO SL

• Xcadey X‑Power Gen 2

• Power2Max NGeco (Easton version)

• Elilee's own EK‑01 power meter

What's in the Box

• 1 × Elilee Carbon Spider (4‑arm / 110mm BCD)

• 4 × chainring bolts (where applicable; check listing for details)

Chainring bolts: The spider uses standard 4‑bolt chainring bolts. For a clean aesthetic, pairing with Shimano Dura‑Ace chainrings and Elilee's decorative covers is a popular choice among weight‑weenies.

Installation Notes

Tools required:

• 10mm hex key / spider removal tool (for Easton Cinch interface)

• Torque wrench with 5mm hex

• Grease for spline interface

• Threadlocker (medium strength) for chainring bolts

Basic steps:

1. Remove the existing spider from your Elilee crankarm using a 10mm hex key (or spider tool)

2. Clean the Cinch spline thoroughly and apply a thin layer of grease

3. Slide the carbon spider onto the spline – ensure full engagement

4. Torque the retaining bolt to manufacturer spec (typically ∼40–50Nm)

5. Mount your chainrings using standard 4‑bolt hardware

6. Torque chainring bolts to ∼8–10Nm with threadlocker

⚠️ Professional installation recommended if you're unfamiliar with Cinch interface setup or torque specifications.
