(Very Early Days Yet, Ready for Super Keen Alpha Testers)

In today’s workshop video with Tom, we’re tackling a full strip-down and rebuild of a beautiful Santa Cruz mountain bike. This bike came in with the "New Year" blues—plenty of wobble in the pivots, a sluggish dropper post, and a whole lot of grit hiding in the linkages.

We walk you through the professional process of extracting and installing frame bearings, utilizing the Alt Alt bearing tool kit and a Wheels Manufacturing press to ensure everything is seated perfectly without damaging the frame.

⚠️ What’s Covered in This Video:

The Santa Cruz Bearing Warranty: A quick look at how you can get replacement bearing kits if you are the original owner.

Pro Tip for Brake Removal: A simple trick using an elastic band to keep your caliper spacers and bolts organized.

Bearing Extraction: Using the @altaltbike kit to safely remove old, gritty bearings from the linkage and yoke.

Parts washer is a @rozonelimited8910 biomemediation smart washer. Amazing bit of kit.

The Clay Problem: See what happens when you don't purge your grease ports for a year, or rather don't push enough through.

Grease Port Service: How to clean and test the internal grease runners and nipples to ensure your new bearings stay lubricated.

Reinstallation & Torque: Checking the exploded view diagrams for correct torque settings (9Nm for the grease nipple) and where to apply thread lock.
