I had exactly the same problem in Shimano 105 road shifter. I solve it by wrapping bleed screw with PTFE pipe tape and it did tightened to damaged threads in bleeding port.

The Canyon Endurace you linked to is a road bicycle, so it might not be able to handle something like a 46/30 as the front derailleur might not be able to be set low enough and the chainline is likely different. If you could get a bike shop to allow you to try the swap, though, it might be worth it because it might work.
The bike will almost certainly be ...

Officially, you would need to use the corresponding GRX front derailleur.
This is because the GRX crank uses a wider chainline, which is the distance from the center of the bottom bracket to the midpoint of the crankset's rings (hat tip to the late Sheldon Brown for the link).
Shimano road double cranks use a 43.5mm chainline (for example, the R8000 ...

I can't speak to GRX specifically, but one of the Old Saws of cycling is "Buy the bike you want" which means to avoid buying a bike with the immediate intention of upgrading/replacing parts.
Generally speaking, a new bike will work well together - by swapping things about, that new-bike feel may diminish.
Unless your LBS is really nice and credits ...

gshenk's post is excellent general answer, here's the specific answer for the setup on the Digger Comp.
The Digger comes with an RX-600 40t crank, RD-RX812 derailleur and CS-M7000 11-42 cassette. The RD-812 derailleur is compatible with wide-range mountain bike 11 speed cassettes (which have different spacing that 11 speed road cassettes). It's not designed ...

The search process should be like this: First, search the web for "campagnolo calima spare parts". The first hit should be a product page that has link to spare part catalog. Download and open the catalog. Search for the page with Calima.
The answer is FH-BU015X1.

It depends. For most gravel bikes it will be an easy, yet expensive, swap. A couple of gravel bikes frames are built in a way that makes shipping a front derailleur as good as impossible. There may not be enough room for the chain stays to clear a second chain ring. What is more, some frames lack mounting positions and the shape or material of the seat tube ...

Does it only click with the QR closed and tight? Tighten the QR only tight enough to hold the wheel in place and spin the wheel. If the click is gone the QR is so tight it is compressing the cones. It may take some trial and error to find the sweet spot where the wheel feels too loose off the bike but just right when the QR is compressed.

In such cases, I often check ebay or similar marketplaces for a used/best offer/parts only item to scavenge the needed part from. One often needs to be patient and make multiple offers before succeeding. As far as compatible replacement parts, si.shimano.com documents may indicate compatible parts if you haven't checked there yet; alternatively, a local bike ...

Any 7/8/9 Speed derailleur with enough capacity (essentially cage length) will work.
Shifting quality is about the system, not a single component. Replacing just the derailleur, even with the very best, will make little difference. However reasonable quality components are often available at discount prices cheaper than low spec components, so shop around ...

What you describe in the first part of your question is normal. Longer lever travel may indicate you need to bleed the brakes. Uneven caliper piston movement is caused by contamination of the piston seals with dirt. Park Tool has a video about cleaning pistons and seals.
However this is bit more worrying:
Sometimes the pistons are cock-eyed, extending from ...

You’re right on. The road shifters have different pull ratio, so you need to use a road front DR. A Sora triple front DR will likely work.

I don't know the severity because I rarely encounter recent mountain FDs and hacky setups for them even less, but what will happen is the contact it makes with the chain when shifting off of the small ring will be suboptimal. That kind of problem will vary with what cog the chain is on in back, i.e. better in the lower gears. There can also be problems with ...

Almost any Shimano 3x10 MTB Derailleur, but Deore FD-M6000 is a good match for what you have now.
Be careful that you match the clamp band type and that you get the correct down pull / top pull version to match your current one.
Down pull is where the cable rises from the bottom bracket.

I cleaned my Shimano Tourney TZ today and i had the same problem (that's why i'm here). I cleaned the bottom wheel and it was clogged with dirt and hairs .I cleaned the top wheel the best i could because i can't remove it. It now moves good enough without having to struggle and breaking the derailleur.
This answer confirms that the top jockey wheel is not ...

Shimano 46 tooth outer chainrings are flat and lack the '3d' profile of the 50 and 52 tooth rings. The 'fancy' bolts you linked to are shaped to cap off the crank spider arms. Those will work with the flat Osymetric rings.
Regular bolts will also work but not look as 'finished'.

Shimano Tourney TY SL-TX50 shifters are 7 speed, so you must have a 7 speed cassette (or more likely freewheel) on the rear wheel. An Acera derailleur is from a 9 speed groupset (or possibly its an older 89 speed one.) The Tiagra front derailleur is from a road groupset and depending on age could be 3x10, 3x9 or 3x8.
You really cannot make any effective ...

As the picture shows the shifter, the derailleur is the bit at the other end, I presume its the shifter that has broken.
Any 7 speed shifter will work. this is a combined shifter so you will need a combined (with brake lever) shifter or you could choose to install a seperate shifter and brake lever.
You will almost certainly need (and be a lot easier) to get ...

Ultegra - https://bike.shimano.com/en-US/product/component/ultegra-6800/FC-6800.html
They have the same PCD and chain line which are the two measurements that show you whether the chainrings will sit correctly. I would be surprised if they weren't compatible based on this ...

It's a Shimano Positron shift cable.
The outer housing is also special.
Picture from WorthPoint.com
I found a few for sale on ebay - not an endorsement.
There were two Positron systems. The first one was very complicated. The since there was no return spring the rear derailleur had two cables to pull back and forth. The later version had one solid wire ...

Yes.
All Shimano MTB groupsets up to 9 speed all used the same derailleur actuation ratio (how far the cage moves for a given cable pull), so all 8 speed MTB shifters are compatible with all 8 speed MTB derailleurs.

You can see an overview of the whole Shimano range, including the hierarchy of groupset series in the line-up chart. You can also drill down into each groupset and see which components are intended to be combined together.
Basically the mountain bike series all start with M and go from M2xxx Acera to M9xxx XTR. Road groups start with R and go from R2xxx ...

I have XTR M9100 brakes.
Recently I have replaced the front caliper with a XTR M9120 4-pot caliper with excellent results.
The rest is absolutely the same, hose, levers, etc. Only the front caliper changed.

It's unclear what you mean by 'changing the shifting system to eTap but stick to the braking system'. You can't separate the two systems.
If you change shifters you are changing the brake levers. Shimano and SRAM hydraulic brake levers and calipers are utterly incompatible as they use different hydraulic fluids (SRAM DOT fluid, Shimano mineral oil).
If you ...

Any Shimano compatible 9 speed road shifter like the Sora you linked will work. While it will be visually different it will perform the same function. The last of these models were produced in 2007. While the Sora shifters you are looking at may be lower on the hierarchy list, they are likely equal to or better than your nearly the 20 year old technology you ...

On the approximately 5 different models of Shimano disc brakes I've dealt with over the years, the caliper fixing bolts are M6 x 18.7mm, and they are socket head cap screws in non- bicycle parlance. This length of fixing bolt would be if you were using 160mm rotors in a post mount set-up. For systems using 180 or 203mm rotors, you'll need about 40mm of ...

I, too, had this problem this year when I purchased an O.E.M. CS-R7000 from a reputable eBay seller. OEM products are typically not sold with retail packaging and this was the case here.
The cassette was wrapped in bubble wrap and newspaper, but the exterior package was a sort of beefed up manilla envelope and sent to me via US postal service. Upon it's ...

Mixing mountain (Tourney TX) and road (Sora R3000) components is tricky at best. But here the answer is easy because while the TX uses a square taper BB, the Sora crankset requires an outboard bottom bracket (cups threaded or pressed into the bikes BB shell with bearings that sit outside the shell). See Shimano's Compatibility Chart. These are completely ...

First thing you should do is undo the bolt that's holding the shift cable until it's completely loose. Then adjust the H screw until it sits perfectly on your highest gear.
Once you have that, then you should screw in the barrel adjuster on your handle bars all the way to the right.
Next, reattach the shift cable bolt to hold the cable tension; you want to ...

Common reasons for a derailleur not getting to the low gears (larger sprockets) is the shift cable slipping through the pinch bolt that secures it on the derailleur, cable housing has come out of shifters or frame stops or bad adjustment via the barrel adjusters.
The common reason for a derailleur not getting to the high gears (smaller sprockets) is the ...

If you don't have it, download a Shimano rear derailleur manual and follow the procedure for adjusting the limits, or follow one of the many Youtube videos, like this one
. The process is the same for most models. The limit screws control how far the derailleur moves in or out.

If you can identify the specific part number on the crank (or just by looking at pictures online), Shimano provides a great deal of information online about compatibility.
For example, if you are using the current Tourney FC-TX801 crank, it uses a standard threaded square-taper bottom bracket, so any square taper crank will work. The SORA R3000 crankset you ...

In general, you may be able to check the bike manufacturer’s page for your bicycle. They will usually list all the components the bike is built with. However, the list may not be comprehensive, especially if the manufacturer mainly sells lower end brands.
Bottom bracket standards can be confusing, because there are a number of variations. In this case, you ...

I have a 52/39 crank set with an hg51 11/32 cassette. The rear derailleur is a Sora rd-3000 and a Sora sl4000 downtube shifter. It works perfectly. For steep hills and for speed. Had an hg51 8 speed 11/28 and changed it. Where I live there are steep hills.

Although it would make unclipping faster, there are a few other things you can tweak to get the same effect without changing cleats.
Maybe you need to reduce your clip tension so it takes less force to unclip.
Practice the instinctive clip-in/out. You really don't want to have to consciously think about "I need to unclip NOW". Rotating your feet ...
