Product Details

Overview & Technology

Wheels Manufacturing Chainring Spacers (CS-0.6, PN 400044) are precision-machined stackable shims engineered for accurate chainline and spacing adjustments. Each bag contains 20 spacers made from 6061 aluminum with a 10mm inner diameter and 0.6mm nominal thickness. These middle-position spacers are intended for use between chainrings or between a chainring and spider where fine adjustment is required. The spacers are CNC-turned from 6061 aluminum for a consistent thickness and a corrosion-resistant silver finish. Because they're lightweight (bag weight ~0.01 lb) and sized to common chainring bolt interfaces, they provide a low-mass, durable solution for dialing in shifting performance and eliminating rub without altering other drivetrain parts.

Key Features & Benefits

Precision thickness options: Available in 0.6mm, 1.2mm and 2.0mm variants so you can fine-tune chainline in small, predictable increments. Use single spacers or stack multiples for custom spacing. Materials and machining: Made from 6061 aluminum for reliable stiffness-to-weight, repeatable flatness and long-term corrosion resistance. The 10mm ID fits common chainring bolt and spacer designs and the polished silver finish resists grime buildup. • Consistent thickness — CNC control for predictable setup. • Stackable — combine sizes for exact chainline correction. • Lightweight — negligible effect on rotating mass.

Fit, Sizing & Compatibility

These spacers are listed as "middle" position spacers — intended to sit between chainrings or between a chainring and the crank spider where a central shim is needed. The 10mm inner diameter matches many chainring bolt patterns and aftermarket bolt kits; however, check your crank/chainring bolt inner diameter and shape before installation. Available thicknesses let you choose fine (0.6mm), medium (1.2mm) or coarse (2.0mm) correction. Common use cases include multi-chainring road and gravel cranks, adapter setups, and custom chainline tuning for single-to-double conversions. They are compatible with most steel and aluminum chainrings and bolt kits — for non-standard or proprietary systems (some integrated frog-eye bolts, Sram/BB30-type spiders) verify clearance and fit first.

Who Should Use These Spacers

Cyclists and mechanics who demand crisp, quiet shifting will appreciate these small but essential spacers. Use them if you notice chain rub, marginal shifting between chainrings, or if you are building a custom drivetrain where precise chainline matters. The bag of 20 gives shops and home mechanics enough stock for multiple builds and iterative tuning. These spacers are especially useful for road and gravel riders adjusting compact and standard double setups, cyclists converting to single-chainring layouts who need spacer stacks, and bike mechanics who want a reliable, repeatable shim option in their toolkit.

Frequently Asked Questions

What does 'middle' position mean for these spacers?

Middle-position spacers are designed to sit between two chainrings or between a chainring and the spider where a central shim is required. They correct lateral spacing without altering the interface on the crank arm side.

Can you stack these spacers to get other thicknesses?

Yes — these spacers are intended to be stackable. Combine different thicknesses (0.6mm, 1.2mm, 2.0mm) to achieve the exact shim value you need. Always re-check chainline and shifting after stacking.

Will the 10mm ID fit my chainring bolts?

The 10mm inner diameter fits many common chainring bolt systems, but not all. Verify your chainring bolt inner bore or any aftermarket adapter measurements before purchase to ensure proper fit.

Are these safe to use with carbon chainrings or spiders?

The spacers themselves are aluminum and safe as long as you follow torque specs for your bolts and avoid creating point loads. When working with carbon parts, use the manufacturer's recommended torque and check for proper seating to prevent damage.

How many spacers come in one bag and what is the part number?

Each bag contains 20 spacers. This product is Wheels Manufacturing CS-0.6, Manufacturer Part #: CS-0.6, Product Number: 400044.

Buying Guide

Choose the spacer thickness based on how much lateral correction you need: 0.6mm for fine tweaks, 1.2mm for medium adjustments, and 2.0mm when a larger offset is required. For precision builds, buy multiple thicknesses and stack them to reach the exact shim value. Check the inner diameter and overall dimensions against your chainring bolt system before purchase. If you're unsure, a 10mm ID spacer is commonly compatible with many bolt kits — but proprietary or integrated systems may require specific parts. Keep a bag of spacers in the workshop for fast, repeatable adjustments and repairs.
