Fawfose Bicycle Pulley Guide Wheel 13T 19T Sealed Bearing Set (Black

Details

• Alloy Body With Sealed Bearings: The 13-tooth upper and 19-tooth lower wheels are CNC-machined from aluminum alloy, rotating on sealed cartridge bearings to shed mud and grit during wet trail rides.
• Drop-In Cage Fitment: The guide wheel set slips directly into standard derailleur cages without special tools, letting you replace worn pulleys between stages or after a dusty gravel segment.
• Drag Reducing Tooth : The wide-narrow tooth shaping holds the chain under lateral loads, minimizing chain slap and improving shift feel when climbing over roots or sprinting out of switchbacks.
• 127-Gram Assembly Weight: At approximately 127 grams, the pair avoids adding rotating mass to the cage, preserving suspension sensitivity and rear wheel tracking on descents.
• Uncoated Alloy Finish: The raw aluminum resists peeling and fading better than painted pulleys, maintaining consistent chain engagement across long-distance bikepacking routes and daily training laps.
