The SRAM XG-1295 T-Type [paid link] cassette is a premium 12-speed cassette designed for SRAM’s Transmission (T-Type) groupsets, offering robust performance and seamless shifting. Correct installation, precise adjustment, and regular maintenance are essential to keep it running smoothly.

This guide provides expert insights into setting up your XG-1295 T-Type [paid link] cassette, troubleshooting common issues, and maximizing its durability.

Tools Required

Before starting, gather the following tools:

  • Cassette lockring tool [paid link] (SRAM T-Type compatible)
  • Torque wrench [paid link] (with correct lockring socket)
  • Chain whip or cassette pliers
  • Degreaser and brush for cleaning
  • Lubricant suitable for drivetrain components
  • Clean lint-free rag

Step 1: Installation of the XG-1295 T-Type Cassette

1.1 Preparing the Freehub Body

Before installing the cassette, ensure the XD [paid link] freehub body is clean and free from debris. Old grease or dirt can cause misalignment or improper seating.

  1. Remove the old cassette (if present) using a chain whip and cassette lockring tool [paid link].
  2. Wipe the freehub splines with a clean rag and apply a thin layer of grease to prevent corrosion.

1.2 Mounting the XG-1295 T-Type Cassette

  1. Align the smallest cog with the corresponding notches on the XD [paid link] freehub. The XG-1295 T-Type [paid link] is a one-piece cassette, making installation easier.
  2. Slide the cassette onto the freehub until it sits flush against the body.
  3. Thread the cassette lockring by hand to avoid cross-threading.
  4. Use the cassette lockring tool [paid link] and torque wrench [paid link] to tighten the lockring to 40Nm (manufacturer’s recommendation). Over-tightening can damage threads, while under-tightening may cause shifting issues.

1.3 Checking Cassette Engagement

Once installed, rotate the cassette backward to ensure it moves freely. Check for any play or misalignment. If the cassette wobbles, it may not be seated correctly. Remove and reinstall if necessary.

Step 2: Adjusting the XG-1295 T-Type Cassette for Optimal Performance

2.1 Ensuring Proper Derailleur Alignment

Since the XG-1295 [paid link] T-Type is part of SRAM’s Transmission system, proper derailleur setup is crucial. SRAM’s hangerless interface means the derailleur mounts directly to the frame, eliminating traditional derailleur hanger issues.

  • Check that the derailleur is properly installed according to SRAM’s Setup Key Tool for precise positioning.
  • Use SRAM’s B-Gap tool to fine-tune the gap between the upper pulley and the cassette’s largest cog.

2.2 Fine-Tuning Shifting Performance

  • Shift through the entire range to ensure smooth, noise-free operation.
  • If the chain struggles to shift into lower gears (larger cogs), slightly loosen the B-tension screw.
  • If the chain hesitates in higher gears (smaller cogs), increase cable tension using the adjuster barrel on the derailleur.

Step 3: Maintaining the XG-1295 T-Type Cassette

3.1 Regular Cleaning Routine

Keeping your cassette clean extends its lifespan and ensures smooth operation.

  1. Remove the rear wheel and use a brush with degreaser to clean between the cogs.
  2. Wipe down the cassette with a lint-free cloth to remove any excess dirt.
  3. Rinse lightly with water (avoid excessive water pressure, which can push grime into the freehub).
  4. Allow the cassette to fully dry, then apply a light coating of lubricant on the chain (not directly on the cassette).

3.2 Checking for Wear and Damage

Inspect the cassette for signs of wear, such as:

  • Shark-tooth shaped teeth (indicates excessive wear).
  • Skipping gears even with a new chain.
  • Chain slip under load, which may indicate the cassette has worn out.

A well-maintained XG-1295 [paid link] T-Type cassette can last 3,000-5,000 miles, depending on riding conditions and maintenance.

Troubleshooting Common XG-1295 T-Type Cassette Issues

4.1 Chain Skipping or Poor Shifting

  • Ensure the derailleur setup key was used correctly during installation.
  • Check chain wear—an overly stretched chain can cause cassette misalignment.

4.2 Cassette Making Noise

  • Inspect for dirt buildup between the cogs.
  • Confirm the lockring is torqued to 40Nm—loose cassettes create creaking noises.

4.3 Inconsistent Performance in High or Low Gears

  • If shifting is inconsistent in the largest cog, adjust the B-tension screw.
  • If shifting issues persist in the smallest cog, check derailleur alignment using the SRAM Setup Key Tool.
