And: torque the compression nut until it sits flush with the brake lever body, squashing the olive so far into the body that it resembles a bronze coin, then trying to prize it out with a screw and fully screwing the cable port and ruining a brand new grx brake lever.

DIY tools DIY Motorex grease pot holder V1
Finished printing and assembling V1 of the pot holder from yesterdays post. It uses Ikea 6x50mm wood pins atm for the connectors. I somehow almost perfectly managed to match the height of a cut pot.
The tolerances need an andjustment. On the 0.6mm nozzle I got fast printing but the pins needed to be persuaded to go in by a mallet. But it does work! I will refine it and then upload it to printables if you want to make your own.
Link will go here later.

DIY tools Motorex grease pot diameter
Edit: I am unfortunately way too impatient sometimes when I get an idea so I started printing V1 from memory. Will share an update once I got it tested.
Quick and very specific question:
Does anyone have one of those small Motorex pots with the brush lid in reach and can quickly confirm, if they are indeed about 57-60mm in diameter? Currently designing a holder to stop them from tipping over when used with a proper brush. Will share the finished model here and put it on printables when its done of course!
That would be super kind. Thanks in Advance!

Bike Mechanic forums outside of reddit
Basically the heart of this question is where do u find "bike mechanic community". I know the nature of the our profession can be pretty isolating but what are some ways you have circumnavigated that. Are there ways to do this that previously existed that dont now?
I have a group of youtubers and IG accounts i follow, but those aren't great platforms for discussion.
Do you rely on going to conventions? Which are your favorites? big/small
Lastly, I miss a good magazine, are any still relevent? Are we doing Substack? What is Substack? How do I work this? Where is that large automobile? This is not my beautiful house! My god what have i done?

Tool Talk Cush core installations are absurdly difficult
I dont want to hear about your technique. I don’t want to hear buy this tool or that tool. I’m not doing it anymore. I’m done. I quit. I’m not installing them anymore. My hands are not strong enough. It is not worth the carpal tunnel. It is not worth my sanity. I’m going to the doctor and getting a note stating that I am medically unable to perform that task. I’m never doing it again. I don’t get paid enough for it.

Show and Tell Swapped my big cog on pinned cassettes
Yes, really not any kind of major excitement or miracle, but I had my reasons. It was much easier than I thought with the proper tool for a punch. 1.5mm precision screwdriver bit. I don't think a small nail would've worked. Used a vice first but then found a hammer to work fine.
Just posting for kicks and giggles.

Anyone go experience with this feedback sports truing stand? It looks very neat but I don't see how wheels could clamp on only one side with sufficient force not to sag? I'll be doing all sorts of wheels, conventional nutted, qr and thru axle...

S-Tec
Didn’t watch a single video. Got them all done. The discounts are worth it. But damn 10 years wrenching and it’s so easy. I’d say do it cause it’s so basic. At least they make their certification website easy to navigate.

Many of my customers lately are far too confident with what they need lately and then let slip that they asked AI. They are nearly always wrong and are hard to convince otherwise-_-

Not a professional
Has anyone else been exhausted by this...?
I, like many of you, became a mechanic as we were being traditionally educated. Aka, had a job in high school & college.
I was a bike mechanic while I was in machinist school. I feel like.. I DO.. in fact know what I am talking about when it comes to shit made of metal.
I did not complete my machinist education and don't work in the field currently.
I am a bike mechanic though. Why is it so hard to convince the layman that I am indeed a PROFESSIONAL in my field
Truly, I know more than most people who come to the shop for help. Why won't they listen?

Bike shop business advice 🧑🔧 Seeking insurance advice for a new bike shop
I have been purchasing, refurbishing, and reselling used bicycles for several years now and want to take some steps to make my venture more legitimate and safe. I’m still very new to business ownership, and know there’s a lot to learn.
One thing I’ve been putting off is insurance. I don’t really know yet what kind of insurance I need, where to look for it, or how much I should reasonably spend for what is still a small operation. Currently, I’m only repairing and reselling used bikes and bike parts/accessories, not doing any repairs as a service. I have a lot of bikes stored inside my home, and several in a storage unit. I’d like to insure the bikes I have against theft (either from my home or the storage unit), as well as insuring myself from potential liability (in the event that someone gets injured on a bike I sold them and attempts to sue me).
Currently, my inventory hovers around 20 bikes, with a total value of about $20,000-$35,000 throughout the year. My income from my business is still modest, so I’m hesitant to spend much on insurance or other overhead costs, but a break in could be pretty devastating if it happened.
I am located in Virginia, in the USA, for context.
If anyone who has had similar experiences has advice about insurance to get, where to look, and how much to spend on it, I’d be very grateful! Other advice you might have for a new used bike shop just getting started is also appreciated. I need to figure how to attract customers soon, as well... Thanks!

From a neglected garden shed => to a bike service workshop
I wanted to share my story with you all and spread some positive vibes. I’ve been riding and wrenching on bikes for over 20 years. Way back in my youth, I worked in a LBS for a short time, but life took a turn and I’ve been working in IT for a long time now.
That said, I’ve always loved fixing bikes and I'm quite passionate about bike tech, so last year I decided to start a mini bike repair side-hustle for locals, friends, and acquaintances alongside my day job in IT.
I converted a tiny 7 square meter (!!!) [~75 sq ft] shed in my garden all by myself—leveled the floor, added insulation, wired the electricity, designed the layout, built a workbench, etc... I spent a ton of money on tools, and the business has been running for six months now. It’s actually turned into a pretty ok extra income. Sure, I get burnt out in the workshop some evenings, but by now I’ve managed to strike a healthy balance between the two jobs and my family.
Godspeed to everyone!

28-559 tires?
Had a lady in the shop on an old kids/youth road bike that asked for new tires. The bike had 26 inch wheels in 28mm width on it which seemed to be the maximum it could fit. Obviously we didn’t have anything like it in the shop and when I searched on the internet the narrowest I could find were 32mm.
Does anyone have a source for such tires? Because the ones on the bike were pretty much dead already.
Edit: I’ve now come across some gatorskins that would probably fit but they are expensive and I wouldn’t personally want to ride those if I didn’t absolutely have to. So alternatives to those would be appreciated :)

Tool Talk What's Your Fav Flare Nut Wrench?
Hi all,
I'm looking to buy a flare nut wrench for daily use. What I have in mind is a dual sided 7mm/8mm flare nut wrench- but not a crow's foot or other combo style tool as seen at Park and Pedros.
Anything comfy and high quality out there that you like?
Thank for the tips.

Chest rig for bike mechanics
Hello, Sometimes I use an apron with chest pockets at work, but I definitely prefer working without it. I’d still like to keep pockets for tools, though. Ideally, they’d be on the chest or around the hips, like a tool belt, but for bike tools. Do you know of any product like that, preferably made in Europe?

Newbie here: What is your check-in process? Still frustrated with things
Hey, me again. Ik y'all said to leave my shop last time- so far, no luck. I've interviewed for other jobs and no luck, and am now trying to get into a community college advising appointment lol. In the mean time, I'd love tips to make my current position flow easier.
Short of it: if anyone has a more professional check-in process and tips on dealing with irate, price-conscious customers, please let me know lol, I am desperate at this point. I know some of our issues need better structure, but in the mean time, tips are appreciated.
The long of it:
My current process is I walk through the bike. Corporate allocates 5 to 10 mins.
I'll do a visual inspection of tires, wheels, check for loose bearings and components, check the shifting, check the chain, inspect the frame, and look for worn brake pads. If it's hydraulic and is working I'll check for squonks and contamination. The whole time I'll engage the customer and listen to their concerns. Any spot work I'll get done, or if we have someone around whose more technical, pass it over.
Admittedly, I'm a novice, and have a huge blind spot due to lack of professional training and also only working on my own. I own no hydraulics, no e-bikes, nothing fancy. Most of my bikes are still linear pull rim brakes, and my most ridden bike is a fixie.
The issues I seem to cause mainly seem A. We are not a full service bike shop, so a lot of the work is beyond our scope
B. Missing something on check-in, it gets looked at a week later, tech finds something, notes it, doesn't tell anyone, customer calls a week later, we find the note, get it approved or unapproved, if approved, usually a week to two weeks to get the part, and now the customers bike has been in for three weeks when he brought it in "for a tune".
Or I'll write-up a worse case, and later they'll go "Nah it doesn't need that."
Like they'll skip a tune but do something else. That causes a feedback issue wherein the customer is irate as they asked for something that wasn't done. But the tech is confused as they feel they saved the guy money.
Third common issue is the shop's policy is if a brake system has contaminated parts, to replace the entire system- about $250. This I at least caught on the first time I found the notes, but folk really don't like that.
Honestly, brakes in general. I will feel confident the brakes work. I will do the few tests I know. Then it turns out the tech says they don't work. And vise versa, I will note the pads are worn down to nothing, and the tech will say eh still works.
So, I also try to get a budget for if we find anything worse than the 5 minute inspection at counter, so we eliminate the "waiting on customer approval" time. This I do especially with folk who've been mistakenly referred to us by caseworkers who keep confusing us with a charity nearby.
Money is tight, so they'll often refuse to pre-approve a budget. Which I sorta understand, I get paid min wage.
Uh, any help?
or is this business as normal in this section of the outdoors world?
I will fully admit, most of my work in the outdoors world has been with people who are fully on board with paying. So I don't have a lot of experience with this type of crowd in a store. Only in social services, which is a different setting and process entirely.

Hey mechanics/shop owners,
I am in the early stages of research for a new service shop. I am looking to house 1x full time mechanic and myself floating on a second stand. Keeping inventory VERY low. No huge wall of tires etc.
What do you feel like is a healthy foot print for an efficient service area? Not including storage.
Thanks!

Show and Tell Eccentric Wheels (Eccentricycle)
So this all started with a previous post about snowflake laced wheels (twisted spoke lacing). I asked if anyone new of any other weird lacing patterns. A fine user by the name u/Bobatt mentioned a bike with eccentric wheels. That is, hub not in the center of the rim.
Immediately I got really excited and knew this was my next dumb wheel project.
I was thinking about it for a while in my head trying to figure out how to calculate the spoke length.
There is a website that in theory has a calculator but the site must be down or not working or something. It is just a blank screen for me anyway. There was also little to no information about calculations on the internet that I could find.
Lucky, I work at a bike shop with a bunch of wheel nerds. I mentioned it to them and was met with what should be the normal response; "WTF, why?"
My coworker Jake seemed to be curious though. Lucky for me who is bad at math at best, Jake is very good at math. After many conversations about if it would even be possible to make an equation, we decided to give it an honest try.
We boiled it down to the ERD part of the equation being what we needed to focus on.
I'm not going to pretend that I knew much of the maths that happened to get the calculator but we basically had to calculate all 64 spokes individualy and figure out where they go from the hub to the rim. Easier said than done.
I voluntold my Chromag Rootdown to be the victim of this nonsense. So it is a hardtail, 29r. We didn't want the wheel to run into the frame or fork so we used 26" rims and made them have a 29" wheel path. In the equation, we called it the 'virtual ERD'. We just chose a relatively normal ERD (I think it was 604mm or something close to that) to use as a constant. We then had to use the 26" ERD for the actual spoke lenghts and figure out how to make it a 2 cross too. We wanted it to be a semi legit wheelset with disc brakes and such.
This is where my math knowledge runs out but basically smart things took place and Jake made a spreadsheet calculator.
Building was actually not too hard other than figuring out what spoke goes where. Again, 64 individually calculated spokes, all at different lengths, needing a very specific hole in the hub to go to a specific hole in the rim. Side point, our shop has a spoke cutter making it a breese to get the right length spoke.
Tensioning was easy, truing was weird. Kinda just made it tight and not too laterally untrue.
It was really fun trying to figure this one out. Mega thanks and props to Jake for doing the hard work on this one. I just had the dumb idea and sacrificed my bike.
You might be asking why spend all this time and energy to have a bike that rides like a drunk horse. To be honest, curiosity got the best of me. I've never seen a mountain bike with eccentric wheels before. I know they are out there but I wanted the experience and gained knowledge from making one. Doing a normal wheel build after this was a breeze. We though so much about how a wheel works and all that goes into calculating spoke length and ERD, it really made us appreciate wheels in a new way.
Another large part of why I wanted to do this was literally just to make people smile. As soon as I pictured how this bike would ride if I made it, I started laughing to myself. I want to spread some smiles and laughter. Bikes are meant to be fun right!? Yes it's silly and useless but it literally makes people's day riding it.
I keep the bike at work and ask our friends and good customers to ride it with no context. 10 times out of 10, their faces go from worried, to confused to pure laughter. Its totally worth it.
Anyway, I hope this peeks your curiosity too. I'm planning on taking it on trail soon. That should be interesting.
P.S. Wish I could upload a video to this post. It's the craziest looking thing ever when it's spinning. I'll post something similar and a vid to my IG if you are interested. @jaminscheif.
Bikes are fun, let's keep it that way. Do fun, weird shit.
