The SRAM Force eTap AXS D2 HRD [paid link] brake set is a second-generation upgrade of SRAM’s mid-tier wireless groupset, designed for performance-focused road riders. With notable improvements in lever ergonomics, refined modulation, and hydraulic disc braking performance, this component has generated considerable interest among amateur racers and seasoned cyclists alike. This article explores real-world rider feedback, technical functionality, installation specifics, and common issues—along with tips on how to customize and get the best out of your Force eTap AXS D2 HRD setup.

Tools Required

  • 5mm Allen wrench
  • Torque wrench with bit set
  • Bleed kit (SRAM Pro Bleed Kit recommended)
  • DOT 4 or DOT 5.1 hydraulic fluid (as specified by SRAM)
  • Clean cloths and isopropyl alcohol for rotor and lever cleanup
  • Bleed block and syringes
  • Cassette lockring tool (for rotor installation)

Installation Overview

The Force eTap AXS D2 HRD system integrates SRAM’s updated lever and caliper design with wireless shifting and hydraulic braking. Real-world feedback praises its improved ergonomics, but precise setup remains essential.

Levers must be installed on the bar with proper tilt to align with rider wrist position. Riders note that misalignment can cause hand fatigue over longer rides. The hydraulic hoses connect internally to flat-mount calipers and must be cut to the correct length before securing with compression fittings.

The caliper bolts must be torqued to specification—riders report issues with misaligned calipers causing rotor rub when torque specs are overlooked. Pay close attention to hose routing, as tight bends increase the risk of internal kinks, negatively impacting lever feel.

Hydraulic Brake Setup and Adjustment

Bleeding the system correctly is the most commonly cited concern among riders. SRAM’s Bleeding Edge technology simplifies this, but feedback stresses the importance of:

  • Using clean fluid to avoid contamination.
  • Maintaining level lever orientation during bleeding.
  • Ensuring no air remains in the caliper or lever reservoirs.

Post-bleed, lever feel should be firm but progressive. Many riders comment positively on the lever’s smaller pivot and faster engagement compared to the first-generation model. Adjust reach and contact point using the hex dials under the lever hoods for a customized braking feel.

Brake Pad and Rotor Compatibility

The Force eTap AXS D2 HRD uses SRAM’s road-standard flat-mount calipers with organic or metallic pads. Users report that stock organic pads offer quiet performance and good initial bite but may fade under sustained descents. Switching to metallic pads improves heat resistance, though at the expense of noise and rotor wear.

Compatible with CenterLine and Paceline rotors, riders prefer 160mm rotors front and rear for better modulation and thermal performance. Lighter riders, however, report satisfactory results with 140mm rear rotors for weight savings.

Maintenance Tips

Riders suggest checking for the following regularly:

  • Rotor bolt torque, particularly after heavy descending.
  • Pad wear, as SRAM’s pads wear faster than some aftermarket options.
  • Lever fluid level and free stroke, which can change over time.
  • Hose integrity, especially around bends or entry points into the frame.

Using SRAM-specific DOT fluid is crucial—riders who tried alternatives experienced degraded lever feel and seal wear.

Troubleshooting Common Issues

Spongy Lever Feel: Often due to incomplete bleeding or micro air bubbles. Riders recommend a second bleed after 1–2 weeks of initial use.

Rotor Rub: Typically caused by misaligned calipers. Toe-in the caliper slightly during installation and then retighten evenly.

Lever Return Lag: Sometimes seen in early setups with overfilled fluid. Re-bleeding with careful fluid volume correction solves this.

Brake Squeal: Reported in wet conditions, especially with organic pads. Riders find that scuffing the rotors and pads with sandpaper or switching to metallic pads reduces noise.

Performance and Modulation Feedback

Across varying terrains, riders note excellent brake modulation, which is the ability to control braking force smoothly. Descending at high speeds, particularly on alpine roads, sees strong praise for lever consistency and fade resistance.

The new pivot location and lighter action levers receive widespread rider acclaim. Users with smaller hands especially value the improved reach adjust range, saying it helps them brake confidently from both the hoods and drops.

Customization Options

The Force eTap AXS D2 HRD system allows for minor but effective customizations:

  • Pad choice: Transitioning to metallic pads for aggressive riding.
  • Rotor size: Mixing 160mm front and 140mm rear for balanced performance.
  • Lever reach/contact point tuning: Ideal for riders switching hand positions often.
  • AXS app customization: Pair brake levers with shifting preferences, such as enabling “BlipBox” or customizing shift functions on auxiliary buttons.

Riders who fine-tuned these aspects reported greater confidence and reduced fatigue during long rides.

Comparison with Similar Models

When compared to Red eTap AXS HRD [paid link], riders highlight that while the Red version offers lighter carbon levers and slightly better modulation, the performance gap is marginal for most. Force D2 offers 95% of the performance at a substantially lower cost.

Versus Rival eTap AXS HRD [paid link], Force D2 is significantly more refined. Testers report noticeably better lever ergonomics, smoother action, and improved modulation.

Compatibility Considerations

Force eTap AXS D2 HRD integrates seamlessly with other AXS drivetrain components. Riders using mixed AXS setups (e.g., Force levers with Red calipers) report full functional compatibility.

The system is not backward-compatible with non-AXS components or mechanical SRAM shifting. For best results, pair with AXS derailleurs and use AXS rotors/pads.

Real-World Rider Sentiments

  • Positive: Riders praise braking power, ergonomic improvement, and consistent feel under high load.
  • Neutral: Some note that pad life could be longer and rotor noise persists in some weather conditions.
  • Negative: Initial setup complexity, especially during bleeding, deters less experienced users.

FAQs

1. How often should I bleed SRAM Force eTap AXS D2 HRD brakes?
Bleeding is recommended every 12 months or sooner if the lever feel becomes spongy or after pad replacement.

2. Can I use 3rd-party pads with Force eTap AXS D2 HRD calipers?
Yes, but it’s best to use SRAM-approved pads for optimal performance and to maintain warranty coverage.

3. Why is my rotor rubbing after installation?
This is often caused by caliper misalignment. Loosen the bolts, squeeze the lever, and retighten evenly.

4. Can I upgrade my Rival AXS levers to Force D2?
Yes. Force D2 levers work with all other AXS components and will improve ergonomics and lever feel.

5. Are these brakes good for gravel or cyclocross?
Yes. Riders using them off-road report strong, fade-free braking and better modulation in technical descents.

6. How do I know if I have the D2 version of Force levers?
Look for the new textured lever surface, reduced pivot distance, and updated hood shape compared to the original Force AXS.

Conclusion

The SRAM Force eTap AXS D2 HRD brake set delivers high-level performance with refined ergonomics and modulation that stand out in real-world riding. Despite a steeper setup curve, the reliability and confidence it offers across road conditions make it a compelling choice for serious cyclists. With appropriate customization and regular maintenance, this system can be a long-term braking solution that rivals top-tier alternatives.
