S-Parts Titanium DUB Self-Extracting Crank Bolt & Cover – AERO

The Marginal Gains Upgrade for SRAM RED, Force & Rival DUB Cranks

When you've already made the big upgrades, performance comes down to the details.

The S-Parts AERO Titanium DUB Self-Extracting Crank Bolt & Cover Kit is designed for riders chasing the final grams from a high-performance SRAM road or XPLR build.

Manufactured from TC4 Grade 5 titanium (Ti-6Al-4V), the complete self-extracting assembly weighs just ~13.6g, replacing the standard crank hardware with a lighter, precision-machined alternative.

Designed for compatible SRAM RED, Force and Rival DUB road and XPLR cranksets, including D1 and E1 generation applications, the AERO version strips the component back to what is required: low weight, high strength and a clean, minimal profile.

This is the kind of upgrade that makes sense when you've already changed the obvious things.

Maximum performance. Minimum unnecessary weight.

Complete kit weight – approximately 13.6g

Key Benefits

• Marginal Gains Weight Saving
  At approximately 13.6g for the complete bolt and self-extracting cover assembly, the AERO version is designed specifically for weight-conscious performance builds.
• AERO Lightweight Design
  A minimalist, extensively machined design developed to remove unnecessary material while retaining the functionality of the SRAM DUB self-extracting crank system.
• TC4 Grade 5 Titanium (Ti-6Al-4V)
  High-strength titanium alloy offering an exceptional combination of low weight, fatigue resistance, corrosion resistance and long-term durability.
• Designed for SRAM DUB Road & XPLR
  Suitable for compatible SRAM RED, Force and Rival DUB cranksets, including D1 and E1 generation applications.
• Self-Extracting Design
  Retains the convenient self-extracting functionality of the original crank assembly for crank removal and servicing.
• Premium Finishing Detail
  Available in S-Parts' range of distinctive titanium colourways, allowing the crank hardware to become part of the overall build rather than simply disappear into it.

When Every Gram Matters

There comes a point in a performance build where the easy weight savings are gone.

The wheels are done.
The cockpit is done.
The crankset is done.
The hardware is done.

That's when components like the S-Parts AERO DUB Crank Bolt Kit start to make sense.

At approximately 13.6g for the complete assembly, it isn't about transforming the bike with one component. It's about taking weight away from places most riders never consider.

Small component. Marginal gain. Exactly the point.

Why Choose S-Parts Titanium Bolts & Screws?

Small upgrade. Massive difference.

S-Parts are one of the most respected names in titanium bicycle bolts and screws, producing lightweight bike hardware designed for riders who care about performance and finishing detail. Since 2010, they’ve specialised in precision fixings for road, gravel, mountain and performance builds — helping riders reduce weight, prevent corrosion, and finish a bike properly.

Whether you’re chasing grams or building a clean custom colourway, S-Parts is one of the easiest ways to upgrade the details that most bikes leave behind.

With 1000+ bolt and screw options, S-Parts covers everything from cockpit hardware and bottle cages to drivetrain, brake and suspension fixings.

Why Titanium?

Stock hardware works — until it doesn’t.

Titanium is trusted across cycling because it offers an elite balance of:

• low weight
• high strength
• corrosion resistance
• long-term durability

S-Parts components are manufactured from TC4 Grade 5 titanium (Ti-6Al-4V) — an aerospace-grade alloy known for excellent fatigue resistance and strength-to-weight performance.

Many S-Parts titanium bolts and screws offer strength comparable to high tensile steel hardware, while weighing significantly less and staying corrosion-free year-round.

S-Parts Bolt & Screw Colour Options

S-Parts titanium hardware is available in 9 standout colourways:

• Blue
• Black
• Candy
• Gold
• Green
• Indigo
• Purple
• Rainbow
• Titanium

Perfect for matching frames, finishing kits, accent builds and custom upgrades.

How Are S-Parts Bolts & Screws Coloured?

S-Parts uses two proven finishing methods to achieve durable, high-end colourways:

Vacuum Nitriding

Used for:
Black, Blue, Gold, Rainbow

A hard-wearing surface treatment designed for durability and long-term appearance.

Anodising

Used for:
Candy, Green, Indigo, Purple

An electrochemical process that creates vivid colours while maintaining titanium’s natural corrosion resistance.

Installation Note

Always follow your component manufacturer’s official installation instructions and torque settings. If in doubt, use a torque wrench and reach out before fitting.

Weights may vary by ±2% due to manufacturing tolerances.
