@GregHoge I've seen this with corrugated cardboard as well. Basically just walk on the carboard and you're heel and cleat will both compress the carboard, add holes for the screws, line the cleat up, line the heel of the new shoe up and you should land pretty close to where you want to be (you can also use this technique by sitting on the cardboard to measure your sit bones if in the saddle market)

Thanks for posting this @mugwump. I'm still riding the shoes I bought after somebody stole mine at the race when Moser was in town...!

That's pretty cool!  When you cleat adjustment, are you talking about minor tweaks or a swap to the same position as before?  

For the latter, there was a hack on GCN with using craft foam and making an imprint of the shoe, drilling out holesfor the screws, the using the foam as a jig to replace the  cleats. I'll see if I can find the video.  I suppose it might  not  work with new shoes of a different model, just same shoes with new cleats.
I'm trying to get the new shoe cleat position to mirror the old.

For replacing cleats on the same shoe, I've been able to use a silver Sharpie on the sole to trace the base plate.  

Since Speedplay has a two-piece cleat, and there are two adjustments to make on the second piece (lateral and heel cant), I also take a picture of the old second piece on the shoe before I remove it.  

While the craft foam idea seems cool and custom, once I ride to the store, do all the work, I've invested far more time and effort.  Cardboard seems like a better bet--even then, it could be simplified by taking a piece of cardboard a bit larger than the shoe(s) from the recycling, cutting out a hole for one's cleat, then both tracing the shoe and having some kind of wood of plastic L piece to place against the shoe.

Lol, no just realizing I haven't bought new road shoes in that long!
(probably should put this in a Cleat Fit thread, or add to a bit fit thread)

Did some more research on the Ergon TP1.  I downloaded the brochure and Ergon shared a video with me.

And it also led to a Victor Campanaerts video.  Turns out, he has the TP1 as well and highly recommends it.

Hi everyone, my tire got punctured today and I have two questions-

Is it a bad idea to mix two different brands/models of tires? I am not sure if I’ll find the same tire in store and would rather not wait for it to be shipped.

Also, any clincher tire recommendations? I am not racing this season so looking for something reliable and not expensive. Would ideally not spend more than $60 per tire. 

Thanks!
Not bad to mix but you should keep an eye on them since different tires and rubber compounds wear at different rates - and especially if one is used more than the other. Also they might have different characteristics - dry grip, better in the rain or cold, puncture protection, etc. ally his means that your bike may handle differently or not as you normally expect.

Recommend you eventually replace with matching quality tires. It also looks more “pro” 😉
For training rides, you can't go wrong with Gatorskins for year round usage.

Another thing to know is that tire brands don't match widths.  In other words, not all 25mm tires measure the same--that's assuming you have the same inner width front and rear rim. Some tires even get bigger over time.  This may or may not be an issue to you.  And if you getting in to optimizing tire pressure, the different widths matter.  
In my experience, unless it's a huge gash where you can see the tube and it starts coming out of the tire when inflated (or if you're tubeless, the sealant isn't working), you likely don't need a new tire.

As for recommendations, I like Continental GP5000 tires.  They're a good blend of performance, puncture resistance, and low rolling resistance.  
^ Second @GregHoge. If the sidewall isn't sliced open and the tread is in good shape (other than the cut), you can usually get away with a touch of super glue in the cut.

I find the Continental 4 Seasons to be a great training tire that doesn't flat often (think I've gotten 2 in the few years I've used them as my winter tire), has great durability and then when you switch to a racier tire (like the GP5000) you appreciate how much faster they feel all the more

I am gonna get more specific here @"JoãoPereira-Webber" get Vittoria Corsas Control (Control is their more puncture resistant version) you can pick 25mm or 28mm -- I would suggest 28s. Get the tan Wall.

Buy two of them. I promise you will notice the difference and go a bit faster.

cheers.
If you rather go with the GP 5000 recommendations above, here it is on 25:

$110 for a pair

on 28, $135 for a pair:
https://smile.amazon.com/Continental-Grand-Prix-5000-Black-BW/dp/B088ND6FNQ/

the normal Conti GP is good enough for puncture resistant, and Joao, you are light enough, that I would suggest against the GP Four Seasons -- the difference in ride quality between the normal GP and 4SGP is signifficant. The normal GP rides amaze, the 4SGP much less so.

The Vittoria Corsas I recommended above will outlast and outlive the Conti GPs by a good lot.
fwiw
I like Vittoria Corsas Control, i use this website , used to be NY based now ship from maine
$52

Mark's option is better. 
Speaking about Conti GP 5000s - I’m currently struggling. I’m switching to latex tubes, and my old tires needed replacing anyway. 

But I’m tireless. Bare rims at the moment, so no riding for the last three days. I simply can’t fit them - even with the tire bead jack. I love the tires once they fit, but yikes. 

I’m on the verge of either going to the shop and saying “sorry, I’m useless” or just biting the bullet and going tubeless. 

Before I do either, would warming them with a blow dryer harm their integrity?

"The big "trick" is getting the bead in the middle cavity of the rim" is the trick with or without tubes.

But also, just go to a bike shop, HillTop or wherever, and when you hand them the wheels/tires give the person $20 and make it clear it is a tip. Then consider tipping once they return them to you too.
Kool Stop Tire Bead Jack, Black

Great tool for mounting difficult tires.
I had to put mine out in the sun for a few hours with them half mounted.  Supposedly that loosens/softens them up.  Still had to use a bead jack and put the already mounted bead in the middle of the rim, but it worked.
@RichardKaufmann I feel your pain. A bit of soapy water on the edge of the rim helps makes things a bit slippier, but perseverance is the best asset with this

I have been considering the Conti 5000 TR for a while , but the horror stories about getting them on the rim put me off, but I finally purchased a pair ,
i was actually dreading installing them , I left them out side in the warm for a couple of hours and surprisingly  the set up was pretty easy .
I'm using the 30mm on hunt rims , tubeless , they  seated 1st time with a floor pump
i think sometimes you get lucky with rim/tire size match ups 
Supposedly TRs solved the mounting issue.  I would switch but they're freaking expensive!
Anyone ever hear of or use this site? For data fans - seems kind of cool

Yea it's a good alternative to Training Peaks and Elevate.  I like the comparison by age group and what not.  Makes me feel less slow and more fast.

Interesting video from GC Performance of him putting a 10-33 SRAM cassette on an Ultegra Di2 crank (and vice versa with a shimano cassette on a Sram axs crank). Seems to work pretty seemlessly if you want some pretty extreme gearing.

caveats for excess wear, shift quality degrading over time, etc. 
Ok guys, I'm looking for tire recommendations.  I've bene on GP5000s for a few years now and with my new wheels getting the tire on/off is ridiculously hard; especially when changing a flat on the side of the road...  After 3 flats in the last 3 days I'm over them.  

What tires are ya'll using?  
Big fan of the Vittoria corsa/ corsa control (a bit more puncture protection on this one) with the gum sidewall. Fast and reliable tire and probably the easiest tire I’ve ever put on
