What you can do at home vs where the shop earns it
Okay. This one's a little different. No wrench work today, just me talking through where the line is, because I get asked this constantly. Somebody at the hardware store, somebody in the driveway, somebody in this class probably by week two. "Should I just take it in?"
Here's the thing. I think most people way overestimate what needs a shop. That's not a knock on shops, I use mine too, for the stuff that's actually theirs to do. But the weekly maintenance, the stuff that keeps a bike from turning into a squeaky, rubbing, chain-skipping mess, that's yours. You've been doing it all class. Truing a wheel with a zip-tie, cleaning a chain, adjusting a derailleur cable. None of that is shop-only knowledge. It's just knowledge nobody bothered to hand you before.
What's yours, at home, no question
- Flats. Every time. Tire levers, patch or new tube, done in fifteen minutes once you've done it twice.
- Chain cleaning and lube. Weekly or every couple hundred miles, whichever comes first. We covered this. Dry-ish and clean beats wet and gunked up, every single time on a dusty trail like the Murdock.
- Brake pad rub and minor alignment. Nine times out of ten it's dirt or a barrel adjuster that needs a quarter turn, not new parts.
- Wheel wobble, minor. Zip-tie, quarter turns on the spokes, patience. Gets you most of the way there.
- Shifting that's skipping or hesitating. Barrel adjuster on the derailleur cable, small turns, test ride in the driveway. We did this whole thing a few lessons back.
- General bolt checks. Seat post, handlebar stem, anything that's worked loose. Right tool, gentle first. If it's not moving with reasonable pressure, stop and figure out why before you round it off. I've got a rounded bolt story I won't repeat here, but trust me on this one.
What's the shop's, and I mean that
- Hydraulic disc brakes. Bleeding the system, replacing lines, any of that. I'm honest about this one, it's not my thing. I ride mechanical disc and rim brakes because I understand them completely, and hydraulics get fussy in a way that punishes guessing. If your brakes feel spongy and a bleed is what it needs, that's a shop trip. Don't experiment on the thing that stops you going downhill.
- Wheel building from scratch. Lacing spokes into a bare hub, from zero. I've done it once. Took me a whole Saturday and it still wasn't great. Truing an existing wheel, sure, that's home territory. Building one new is a different skill and honestly the shop's faster and better at it than I am.
- Headset and bottom bracket overhauls, the stuff you maybe do twice in the life of a bike. Specialized tools, press-fit tolerances, not worth owning equipment for one job every few years.
- Frame damage. Cracks, anything structural. Not a home call, ever.
The judgment call in the middle
There's a gray zone and I want to be straight with you about it instead of pretending there's a clean line. Grinding noises you can't isolate. A wobble that a zip-tie truing job doesn't touch after real effort. A derailleur that's bent, not just misadjusted. That's where you try the home fix once, honestly, and if it's not working after a reasonable attempt, you stop forcing it and take it in. The tell is usually: are you making progress, or are you just making noise and getting frustrated. If it's the second one, quit and go to the shop. No shame in that. I still take my own bikes in for stuff.
This is basically what happened with Jocelyn's brakes, actually. They were grabbing on one side, classic barrel adjuster fix, I walked her through the whole thing start to finish. Next time it happened she just did it herself without asking me. Didn't need the shop, didn't need me either, which honestly was the whole point of teaching her in the first place. That's the test for whether something belongs at home. Can a person learn it once and repeat it. Barrel adjusters, yes. Hydraulic bleeds, less so.
The money angle matters here too, since I talk about it constantly. A basic tune-up at a shop runs you real money, and most of what's in that tune-up is stuff you now know how to do yourself. Save the shop trips for the things that actually need their tools and their experience. That's not cheaping out, that's just knowing what you're paying for.
Before next time
Look at your own bike and sort it into the two piles, home job or shop job, honestly, not optimistically. We'll put it all together next time and run the full tune-up in order.
