A handwritten thank-you note just hits differently.
It was wonderful helping Stacey troubleshoot her “cranky bike” and get her back in the saddle. I especially appreciate hearing that she wants to return for a hands-on bicycle repair class and become more familiar with working on her own wheels.
Thank you, Stacey, for taking the time to write such a thoughtful note. This is exactly why I enjoy teaching and helping people with their bikes.

Do you need mechanical experience before taking a bicycle repair class?
No. Bike Teacher’s beginner classes start with the fundamentals, including bicycle safety inspections, flat repair, wheel removal, brake and shifting adjustments, drivetrain inspection, and proper tool use.
Classes are hands-on and kept small for better individual instruction. Students may also bring bikes to class and learn from real repair and maintenance needs.
Whether you want to maintain your own bike, handle trailside problems, or begin developing bicycle mechanic skills, you can start without previous experience.

Don’t wait until your chain starts skipping to check it!
As a bicycle chain wears, it begins to wear down the cassette and chainrings along with it. Replacing a worn chain early can save you from having to replace several much more expensive drivetrain components later.
A chain-wear gauge makes this a quick and easy check. A little preventive maintenance can save you a lot of money—and keep your bike shifting smoothly.

🚴‍♂️ Carbon Bike Safety Check After a Car vs. Bike Incident

A rider brought in this beautiful TIME carbon road bike after being hit by a car. Thankfully, the rider only suffered a few bumps and bruises—but whenever a carbon bike is involved in an impact, a thorough inspection is essential.

Many people ask if there’s a machine that can tell if carbon is damaged. While there are advanced inspection methods used by manufacturers, most bike shops don’t have access to specialized equipment like industrial imaging. That means the inspection relies on experience, careful observation, and systematic testing.

Here’s what I checked:
✔️ Complete safety and bolt inspection
✔️ Carbon tap test, listening for changes in sound that could indicate internal damage
✔️ Close inspection for paint chips, cracks, or hairline fractures that could suggest carbon damage underneath
✔️ Careful test ride to listen and feel for unusual noises, flex, or vibration

The good news? The frame, fork, and handlebars all passed the inspection with no signs of structural damage.

The bad news? The rear wheel wasn’t so lucky. It had a significant dent at the braking surface that could be felt every time the brakes were applied. Damage like that can’t be safely repaired, so the correct solution is to replace the wheel and transfer the tire, cassette, and other components to the new wheel.

Incidents like this are a great reminder: after any crash—even one that seems minor—don’t assume your bike is safe to ride. A careful inspection can catch problems before they become dangerous.

Stay safe, ride smart, and always inspect before your next ride.

🔧 Inside a SRAM SX Shifter!

Ever wondered what the inside of a SRAM SX shifter looks like?

This side cover accidentally came off during service, but on the SX (and many similar SRAM shifters) you normally don’t remove this cover to replace a shift cable.

Instead, simply remove the small rubber cable grommet, and that’s the proper entry/exit point for installing a new cable. It’s a quick detail that can save you time and prevent unnecessary disassembly.

Sometimes seeing what’s inside helps you understand how these shifters work—even if you never need to open one.

Have you ever accidentally taken apart a component that didn’t need to come apart? 😄

🔧 Don’t give up on a stripped or cross-threaded headset bolt just yet!

This bike came in with a cross-threaded top cap bolt that was extremely tight. Instead of reaching for a drill, I grabbed my Park Tool THH T-handle hex wrench. The black “Strip-Gripper” style tip is designed to bite into damaged hex sockets, giving you a much better chance of removing stubborn bolts without making the problem worse.

Once the bolt was out, the next step is inspection:
✅ Are the bolt threads damaged?
✅ Is the star nut still usable?

If the star nut is damaged, it’s usually not the end of the world. Simply drive it farther down the steerer tube and install a new star nut above it. It’s a simple repair that can save the fork and get the bike back on the trail.

Sometimes the right tool—and a little patience—turns what looks like a disaster into an easy fix.
