How to Install

HSC Ceramics™ Product Installation Guide

General Recommendations

We strongly recommend that all ceramic bearings and related products be installed by a qualified mechanic using proper tools.

Preparation

Installation Instructions

Threaded Bottom Brackets

Use the correct bottom bracket spanner for English or Italian threads. Torque should be around 40Nm.

Thread Bottom Bracket Removal/Installation Tool

Pressfit Bottom Brackets (with Cups)

Use a proper bottom bracket press tool. Ensure the correct drift size is selected for your frame and bearing size.

Pressfit Bottom Bracket Installation Tool

It is recommended to apply HSC Anti-Creaking Grease to eliminate small play, which is key to solving the pressfit bottom bracket creaking issues.

HSC Anti-Creaking Grease

SRAM GXP Cranks

Includes a 2mm black plastic spacer and a metal wave washer:

  • Only use the spacer or washer if there is play after crank installation.
  • If your current setup uses a spacer/washer, replicate that configuration to eliminate play.
  • Install these parts on the drive side only as needed.

Instructions for Specific Bottom Brackets

Rear Derailleur Pulleys

  • HSC pulleys are CNC machined, and the upper and lower wheels are identical, so you can install either one in the upper or lower position.
  • Pulleys are compatible with 10-speed, 11-speed, and 12-speed systems from Shimano, SRAM, and Campagnolo.
  • For 10-speed Shimano and SRAM systems, spacers are required, we’ve included 4 metal spacers with your purchase (use one on each side of each pulley, positioned outside the dust cover). It can be helpful to apply a small amount of grease to the dust cover to hold the spacer in place before inserting the bolt.
  • For 11-speed Shimano and SRAM systems, no spacers are required.
  • For 12-speed Shimano Ultegra system, no spacers are required.
  • For 12-speed Shimano Dura Ace system, no spacers are required
  • For 12-speed Shimano 105 system, 12-speed SRAM system and 12-speed Campagnolo system, please install the pulley wheels without spacers initially, they should fit as is. However, in some cage setups, spacers may be required. We’ve included 4 metal spacers with your purchase (use one on each side of each pulley, positioned outside the dust cover). It can be helpful to apply a small amount of grease to the dust cover to hold the spacer in place before inserting the bolt.
  • We include a 4mm ID metal sleeve for SRAM 4mm bolts; select this option if needed.
  • No oil or grease lubrication is needed for HSC ceramic pulley wheels.


Wheel Bearing Installation Guide

Follow these steps to correctly install new wheel bearings into your hub. Proper tools and careful technique will ensure long-lasting, smooth performance.

Step 1: Prepare Tools and Bearings

  • Gather your new bearings, a bearing press (or a drift that matches the bearing's outer race), and grease.

  • Make sure bearings are clean and undamaged before installation.

Step 2: Clean the Hub Shell

  • Wipe the inside of the hub shell with a clean cloth.

  • Remove any dirt, debris, or old grease to ensure a secure fit.

Step 3: Apply Grease

  • Lightly grease the bearing seats inside the hub shell.

  • This helps ease installation and reduces friction and corrosion.

Step 4: Position the Bearings

  • Align the new bearing squarely with the hub shell opening.

  • Ensure it is properly centred before pressing.

Step 5: Press the Bearings In

  • Use a bearing press or a soft mallet with a matching drift to press the bearing into place.

  • Only apply pressure to the bearing outer race; pressing the inner race may damage the bearing.

  • Apply slow, even pressure to avoid misalignment.

Step 6: Reinstall the Axle

  • Insert the axle carefully through the bearings.

  • It should slide smoothly without any force.

Step 7: Reattach End Caps

  • Secure the end caps back onto the hub.

  • Check that everything is seated correctly and there is no play.

Step 8: Test the Hub

  • Rotate the hub by hand.

  • It should spin freely and smoothly, with no unusual resistance or noise.
