Yeah I've been in the bike shop and service industry a long time and ive never seen someone do this before. The reason is it wouldn't really net you anything because any good mechanic can gat any nice brake on any nice frame yo feel fantastic and it would be a way better use of time to bleed some air from the system or get nicer/new rotors/pads.
Calipers arrive to shops installed most of the time and we can't afford to do this stuff to every frame.
The only place you'd see this is at a boutique road bike shop so please don't go into a shop expecting things like this to be routine

It's a shameful video to bike manufacturers, espcially for the price they charge for high-end, FAULTY frame.
This promblem shouldn't exist.

People who are close enough to you to benefit from your service are fortunate. The rest of us are in a wilderness that you apparently can’t imagine 🤣 I’ve had LBS’s in my area sell me a bike with the brake calipers loose, I’ve had them ruin a frame entirely, ruin wheels entirely, etc. Over the years I’ve learned to be as self sufficient as possible, and videos like yours have been a godsend. I wouldn’t for a minute claim to be a pro mechanic, but most “pro mechanics” probably shouldn’t claim that either.

Crazy how you're demonstrating this on S-Works frame

Great explanation, but it's very sad that QC on a frame as expensive as that S-Works is so bad that it's not being delivered faced correctly from the factory. I expect some of the Decathlon frames to need facing, not S-Works frames that cost a small fortune.

You should send the bill to the manufacturer instead of the client!
A bike should never leave the factory like that!

If the day ever comes that I can afford a superbike, I’m definitely gonna be driving the few hundred miles to your workshop to keep the thing maintained! 🚴 Love these technical videos.

Seems like one would have to be a bit of a mug to pay the S Works premium. At these prices I would expect all this to be Bob on.

That's the kind of tan-line you expect from a bike mechanic 😂

This is an awesome video, I'm totally sold on rim brakes 😂

The absolute irony in me just having done this today on a Specialized Crux delivered to my shop with this exact problem.

You’re 100% right , the park DT5.2 is a nightmare of a tool to use. Also I find that most rear flat mounts are not square and require facing from the factory . I really hope the industry gets there act together and resolve this issue

There is a stop collar hight setter that you could  have used on the Park tool to match height on both faces.

I'm so glad it's not just me that loathes that tool, I can't believe the carbon cutter doesn't even attach to the tool, seems like an afterthought. I have a rant every time I get it out of the box 🤣

It's one thing for a shop to have the tool, it's another for them to know how to use it and yet another to find one that will discuss the procedure with you in order for you to be confident enough to let them undertake the job.

I had this done and it absolutely makes a difference. Not only in height, but in the correct alignment to the axle path. I would also say your manufacture would likely never even know if you had a warranty claim.

I think every 10 or so videos I have to express how much I love this channel. This little wave of cycling "enlightenment period" YouTube content creators (Macdec, Peak Torque, Hambini, Dylan Johnson, Friction Facts, Road Cycling Academy) is damn refreshing - rationale, logic, reason... fan-bloody-tastic.

(Especially with the hoarde of dorky industry shill channels out there).

Thanks MCW for a clear explanation of the proper way to solve this real problem,  as I encountered recently. All was good until torquing down the caliper, when you could see it twist, because the mounts were not flat and level. LBS had the correct tool to fix it. Maybe some of the comments you received are from people who never saw these issues, or misunderstood what they were seeing. Cycle industry lacks trained technicians which didn't matter so much years ago, but modern tech has such fine tolerances that you can't get away with  sloppy treatment of expensive engineering.

Love what you are doing raising the standards for the industry and the bike shops. Too many bodges out there and frustrated customers with poorly performing bikes.   Then wasting resources on money on replacement parts that wear out too fast.

Awesome stuff

finding a bike shop with facing/alignment tools is such a headache, but truly it is the manufacturer's fault to not do this before the frame leaves the door. as customers we shouldn't accept it.
