Product Description

SPRILL X110 3-S 110BCD Full-Cover Narrow-Wide Chainring

The SPRILL X110 3-S is a premium 110BCD 4-bolt narrow-wide chainring designed for clean, lightweight 1x road bike builds.

CNC-machined from high-strength 7075-T651 aluminum, the X110 3-S combines a distinctive full-cover hidden-bolt design, a 3mm offset, and a narrow-wide tooth profile for secure chain engagement.

Available in 46T, 48T, 50T, 52T, 54T, 56T and 58T, giving riders a wide gearing range for everything from everyday road riding to high-speed flat terrain.

Full-Cover Hidden-Bolt Design

The X110 3-S features a distinctive full-cover design that conceals the mounting hardware.

Instead of leaving the chainring bolts visually exposed, the mounting area is integrated into the overall chainring profile for a cleaner and more minimalist appearance.

The enclosed structure also helps reduce the direct entry of dirt and debris around the mounting area.

The result is a chainring that combines:

Clean Appearance · Practical Design · Structural Rigidity

7075-T651 Aluminum Construction

The chainring is CNC-machined from a solid piece of 7075-T651 aluminum alloy, selected for its excellent strength-to-weight characteristics.

Compared with lower-strength aluminum alloys commonly used in bicycle components, 7075-T651 is well suited to drivetrain applications where stiffness, durability and low weight are important.

Material Advantages

• High strength
• Excellent rigidity
• Low weight
• Good wear resistance
• Suitable for high drivetrain loads

High Rigidity & Direct Power Transfer

The X110 3-S uses structural ribs and carefully positioned CNC-machined surfaces to maintain rigidity while removing unnecessary material.

The reinforced structure helps resist deformation under pedaling loads, providing a solid connection between the crank and chainring.

This is particularly important during:

• Hard acceleration
• Sprinting
• High-power efforts
• Climbing
• Long-distance riding

Narrow-Wide Tooth Profile

The alternating narrow-wide tooth design is engineered to match the inner and outer links of the chain more closely.

This improves chain engagement and helps reduce unwanted lateral chain movement on a 1x drivetrain.

The design provides secure chain retention without requiring a front derailleur for chainring shifting.

Wide Range of Tooth Counts

Available sizes:

46T · 48T · 50T · 52T · 54T · 56T · 58T

The broad range makes it easier to select gearing according to terrain and riding style.

Smaller options can provide easier gearing for rolling or climbing-oriented routes, while larger chainrings are better suited to riders looking for higher gearing on fast, flat roads.

Precision CNC Machining

The X110 3-S is machined from a solid aluminum plate using precision CNC manufacturing.

The rear of the chainring incorporates carefully designed machined areas and structural reinforcement to remove unnecessary material while retaining rigidity.

Special attention is paid to thickness around critical mounting areas, balancing:

Low Weight + Structural Strength

Beveled Structural Details

Multiple surfaces feature CNC-machined bevels.

These details reduce unnecessary material while giving the chainring a more dimensional, premium appearance.

Rather than using a completely flat full-cover design, the geometric surfaces create a distinctive modern aesthetic that pairs well with performance road bike builds.

Anodized Surface Finish

The 7075 aluminum receives an anodized surface treatment for a clean, durable finish.

Available colors include:

Black · Silver · Purple

The anodized finish complements the CNC-machined surface and gives the chainring a refined appearance.

Specifications

Size & Weight

Actual weight may vary slightly due to manufacturing and measurement tolerances.

Compatibility

According to the supplied specifications, this chainring is designed for selected 110BCD 4-arm road cranksets, including compatible models in the following families:

Shimano R2000 / R3000 / 4700 / 5800 / 6800 / 9000

It can also be used with compatible 110BCD power meters that match the required mounting geometry.

Important

110BCD alone does not guarantee fitment.

Different crank generations can use different arm shapes and mounting interfaces even when they share the same nominal BCD.

Please confirm:

• 110BCD
• 4-bolt mounting
• 3mm offset requirement
• Crank model
• Mounting shape
• Frame clearance
• Required chainline

If you are unsure, please send us a clear photo and the exact model of your crankset before ordering.
