Product Details

Overview & Technology

SRAM 2005-09 X9 Pulley Set (00.0000.200.615) is the factory replacement guide and tension pulley pair engineered for the X9 rear derailleur with the medium/long (M/L) cage. These pulleys match OEM spec for spacing and tooth profile, ensuring the derailleur tracks the cassette correctly and keeps chain wrap consistent across the range. Construction is optimized for long life and low drag — each wheel is molded from a rigid, glass-reinforced polymer to resist wear and noise, while the rotating interface uses sealed stainless-steel cartridge bearings (or long-life bushings depending on production run) to deliver smooth rotation under load. The result is quieter, more consistent shifting and lower drivetrain friction compared to worn or degraded pulleys.

Key Features

What makes this pulley set stand out: • OEM fit: Designed specifically for 2005–2009 SRAM X9 M/L cage derailleurs (SRAM model RD-SPP-A0, Mfg #: 00.0000.200.615). • Durable polymer wheels: Glass-reinforced nylon construction resists groove wear and lateral flex under side loads. • Low-friction bearings: Sealed stainless-steel cartridge bearings (or high-quality bushings) for smooth rotation and extended service life. • Pair included: Both upper (guide) and lower (tension) pulleys supplied to restore proper pulley spacing and alignment. Each feature contributes to improved shifting precision, reduced drivetrain noise, and easier long-term maintenance — especially useful for older builds where replacement parts must match OEM geometry exactly.

Fit & Compatibility

Compatibility: This pulley set is compatible only with SRAM 2005–2009 X9 rear derailleurs fitted with the medium/long (M/L) cage. Confirm your derailleur's model year and cage length before ordering. Manufacturer part number: 00.0000.200.615; SRAM Model ID: RD-SPP-A0. Notes on interchangeability: These pulleys are OEM replacements and match the X9’s tooth profile and spacing. They are not universal—older or newer SRAM models, other cage lengths (short/medium vs. medium/long differences), or non-SRAM derailleurs may require different pulley geometry or spacing.

Who It's For

This pulley set is for mountain riders, home mechanics, and bike shops maintaining older SRAM X9-equipped bikes from the 2005–2009 era. If you ride an X9-equipped hardtail, trail bike, or all-mountain rig and notice sluggish, noisy, or inconsistent rear shifting, replacing worn pulleys with an OEM pair will often restore crisp performance without replacing the entire derailleur. Recommended for enthusiasts who prefer OEM-spec parts to preserve original shifting characteristics and for anyone rebuilding or refreshing a vintage or well-used drivetrain.

Frequently Asked Questions

Are these pulleys compatible with all X9 derailleurs?

These pulleys are specifically for SRAM 2005–2009 X9 derailleurs with the medium/long (M/L) cage. They will not fit X9 variants with different cage lengths or other SRAM models unless stated. Always check the derailleur model year and cage length before purchasing.

Do the pulleys use sealed bearings or bushings?

SRAM supplied these pulley wheels with sealed stainless-steel cartridge bearings on many production runs, though some batches used high-quality bushings. In either case, the replacement set is designed for low-friction rotation and long life; inspect your original mounting hardware and spacers during installation.

What tools do I need to replace the pulleys?

Replacement typically requires a small hex wrench or T25 Torx (depending on bolt type), a torque driver for final tightening, and light grease. Remove the derailleur cage, swap out pulleys, clean mating surfaces, and torque the bolts to SRAM’s spec for safe operation.

Will replacing pulleys improve shifting performance?

Yes — worn or grooved pulleys increase chain friction and can cause noisy, slow, or inaccurate shifting. Installing new OEM pulleys restores proper tooth profile and spacing, often returning the derailleur to near-factory shifting quality without replacing the whole unit.

How long do replacement pulleys usually last?

Service life depends on riding conditions, mileage, and maintenance. Under normal trail use, OEM-quality pulleys typically last thousands of kilometers; heavy mud, grit, or lack of maintenance will shorten life. Inspect pulleys for tooth wear, lateral play, or rough bearing feel during routine drivetrain checks.

Buying Guide

When replacing rear derailleur pulleys, verify exact model fit (derailleur model and cage length) and choose OEM-spec parts when preservation of original shifting geometry is important. For SRAM X9 (2005–2009) derailleurs, this pulley set matches tooth profile and spacing to keep indexing accurate. Check whether your existing pulleys use sealed bearings or bushings; sealed bearings offer lower rolling resistance and simpler service, while bushings can be robust in dirty conditions. Replace pulleys as a matched pair and inspect mounting bolts and cage for wear during the swap to get the best, longest-lasting result.
