Highlights

Key features

Stone taille le disque dans une plaque d'aluminium 7075-T651 de 8 mm, d'une dureté HB150, usinée à 0,03 mm près.

Onze dentures au choix. Sur un cadre titane CYKL en mono-plateau, la limite est de 52 dents : les 54 à 58 dents la dépassent.

Dents larges et étroites en alternance : selon Stone, la chaîne tient mieux, fait moins de bruit et la boue se dégage mieux. Version pour chaînes standard 9 à 12 vitesses.

Fixation directe sur les manivelles Easton EC90 SL Cinch et celles à la même interface, comme les Cybrei GP-3, ainsi que les araignées et capteurs au même standard.

Description

Stone Aero Direct Mount Chainring (Easton Cinch / Cybrei Standard)

Engineered to optimize aerodynamics and eliminate drivetrain friction, this solid CNC-machined chainring mounts directly onto the Easton Cinch interface and Cybrei carbon crankarms. Available in a full range from 38 to 58 teeth, it covers every riding discipline: agile gearing for gravel (38T–44T), smooth rolling on the road (46T–50T), or maximum power transfer for time trial and track racing (52T–58T). Its 0.03 mm machining precision and Narrow-Wide tooth profile lock the chain in place without an external chain guide.

Key Features

7075-T651 Aluminum: Machined from aircraft-grade alloy (Aleris) ensuring total lateral stiffness under heavy pedaling loads and increased wear resistance.

38T to 58T Tooth Range: A comprehensive selection of sizes to precisely tune your gear ratios to your discipline, from aggressive gravel to time trials.

Narrow-Wide Profile: Self-cleaning alternating narrow/wide teeth to hold the chain securely and reduce mechanical friction noise.

Easton Cinch & Cybrei Interface: Direct mount with zero play on Easton EC90SL and Cybrei carbon cranks, featuring a 46 mm chainline (3.5 mm offset).

Compatibility

Compatible with Easton EC90SL cranksets and Cybrei carbon crankarms featuring the Cinch standard. Works with 9, 10, 11, and 12-speed MTB chains, as well as 9 to 12-speed Shimano road chains and 9 to 11-speed SRAM road chains. This chainring is not compatible with SRAM AXS 12-speed and 13-speed Flattop flat-backed chains.

Apply neutral grease to the Cinch interface splines and torque to the spec recommended by your crank manufacturer. Have a question about tooth count or chain compatibility? Write to us.

Shipping and payment

Shipping Policy

Shipping costs are strictly separate from product prices and are transparently displayed at checkout. Our shipping rates are based on a weight-based general profile for components, accessories, and apparel, combined with secure flat-rate profiles for technical products (framesets, complete bikes, wheelsets). For multiple-item orders, shipping fees naturally accumulate to cover ad-valorem insurance and the required protective packaging for your gear.

Our Specialized Carriers:

Colissimo & Chronopost: For standard home delivery of components, framesets, and wheelsets.

Mondial Relay: Only available for lightweight components and accessories eligible for pickup point collection. For safety reasons and to avoid any risk of damage or oversized package refusal, complete bikes, framesets, and wheelsets are not eligible for pickup point delivery.

Geodis: Freight carrier specialized in oversized cargo, mandatorily used for the shipment of all our complete bikes.

Transit and Inspection at the Montpellier Workshop

All our frames, complete bikes, AND all CYKL components must transit through our workshop in Montpellier. Every frame and bike is assembled and customized on-site. CYKL components as well as select partner brands (such as Elitewheels wheelsets or Cybrei cranksets) also transit through our workshop prior to being shipped to you.

Direct Partner Shipping (Short Circuit)

For certain accessories and standard CNC-machined parts from our retail catalog (notably chainrings and cranksets from our partner Stone), shipping may be fulfilled directly from the partner brand's logistics warehouse in Asia. This direct route applies exclusively to machined parts that require no prior assembly in our workshop, thereby reducing transit times and minimizing the carbon footprint of double transport.

Mixed Orders and Split Shipping

If your cart contains items immediately available at our Montpellier workshop alongside items requiring lead time (Pre-order products or stock held by our international partners), CYKL defaults to split shipping:

Priority Shipment: In-stock components and gear at the workshop are shipped to you immediately without delay—unless you specify otherwise.

Secondary Shipment: Frames, bikes, or components on pre-order or requiring custom preparation are shipped in a second dispatch as soon as they are received.

"Pre-order" Status

The "Pre-order" label indicates that the item (or one of its components) is currently en route to our Montpellier workshop or temporarily out of stock.

Additional Transit Time: Confirming a pre-order initiates the item's shipment to our workshop. This adds an estimated average lead time of 15 to 20 business days. This timeframe covers international transit from our specialized partners' workshops to Montpellier, receiving, quality control inspection, and final dispatch to your address.

Logistics Disclaimer: This 15 to 20 business day timeframe is an observed statistical average. CYKL has no direct control over international freight transit speeds or customs clearance delays. These lead times are provided for informational purposes only and do not constitute a contractual guarantee. No order cancellations or claims resulting from delays beyond this estimated timeframe will be accepted.

International, Customs & Taxes

We ship our frames, components, and bikes worldwide. For all deliveries outside the European Union (Non-EU, including the UK, Switzerland, and overseas territories), the following import conditions apply:

Taxes and Duties Payable by the Customer: Prices are displayed exclusive of local import taxes. All customs duties, local value-added taxes (import VAT), customs brokerage fees, and local import taxes required by the destination country are the sole responsibility of the recipient. CYKL has no control over sovereign tax policies and cannot estimate these amounts in advance.

Delivery Refusal: If the recipient refuses delivery upon presentation (specifically due to refusal to pay customs fees), or if the package is returned due to lack of clearance/claim, the full cost of actual round-trip shipping, as well as any customs duties and processing fees charged to CYKL for repatriating the goods, will be directly and fully deducted from the order refund.

Receiving Protocol

The technical integrity of your equipment is our top priority. Upon delivery—especially for bike shipments via Geodis or wheels and frames via Chronopost—adhering to the inspection protocol is mandatory to validate transit insurance coverage:

  1. Immediate Inspection in Carrier's Presence: Before signing the delivery slip (paper or electronic terminal), you must inspect the outer condition of the box, security tape, and internal contents. The carrier is legally obligated to allow you time to perform this check.
  2. Specific Written Reservations: In the event of observed damage (crushed, torn, or punctured packaging, impact marks, scratched or cracked components), you must write explicit, detailed, and specific reservations on the delivery slip (e.g., "Box punctured on right side, frame headtube scratched due to impact").
    Note: The generic phrase "subject to unpacking" holds no legal value and invalidates any recourse against the carrier.
  3. 48-Hour Workshop Notification: Any transport damage properly documented on the delivery slip must be reported in writing to our technical support team at contact@cykl.store within a strict deadline of 48 business hours, accompanied by clear photos of the packaging, shipping label, and damaged equipment. Without explicit and detailed reservations recorded upon delivery, the shipment is legally deemed delivered in perfect condition, and no transport-related claims or warranty requests will be accepted thereafter.
