I have the same derailleur as you, and I cannot find a B screw either. However, it looks to me that your axle is not properly seated in the fork slot (1/2" gap). Try seating the axle all the way in to see if that makes a difference. I need a B screw to back my gear pulley away about 1-2mm, as it's grinding a little when using the largest sprocket. I ...

You don't say specifically what your set up problems are but when training mechanics we recommend starting with the fundamentals and then working upwards, not skipping steps or assuming that things are correct, that may later prove not to be. That potentially saves you from a lot of lost time trying to get something to work where you have an undetected, ...

The H-screw aka b-tension aka angle adjustment is meant to be adjusted in the lowest gear position for any rear derailleur where the guide pulley is offset from the cage pivot, which is most of them, including this. The manufacturer recommended distance will always be for that position. For conventional road derailleurs like this, that 5mm number really ...

It's weird because that metal tab should be there, and the chain should be that side of it, without contact. It's there to catch the chain in case of derailment, and would normally be closer to the outer cage plate. The two main plates of the derailleur cage don't look parallel to me, which would suggest they are bent out of alignment, perhaps from the crash ...

Based on the picture and the description my best guess is that part of the inner or outer cage plate (part number 3507 or 926) isn't quite straight. A little strategic bending might be in order to prevent the chain from rubbing. I know this isn't your derailleur but here's an exploded diagram with part names for reference. I couldn't find a Claris diagram. ...

If you've replaced the cabling and you see it slackening off with no derailleur response, there must be some added resistance in the movement of the derailleur itself. I suspect it is simply the pivots of the derailleur which need some lubrication. Either a spray of teflon lube on each pivot point or a drop of oil. Then, if you have the wheel off the ground, ...

The derailleur in the first photo doesn't appear to be mounted correctly. See how there's a big gap between the axle and dropout slot? I think you should just go with a regular, bolt-on derailleur. Non-replaceable hangers are usually found on steel frames (check yours with a magnet) and are perfectly fine to use. With steel, you can just bend it back into ...

TLDR: no that won't work. Shifters pull a certain length of cable per gear, derailleurs have an actuation ratio. Cable pulled x actuation ratio needs to match sprocket spacing. All Shimano road groups up to 10 speed (excluding Tiagra 4700 and GRX RX400 series) used the same derailleur actuation ratio so derailleurs of different 'speeds' could be mixed and ...

Assuming the 2013 Tiagra shifters are the 4600 series, it's not officially supported due to (indeed) difference in cable pull. I expect getting a smooth shift is going to be difficult if not impossible. If for some reason the Tiagra shifters are newer (and 4700 series) then the 10 speed shifter will work with the 11 speed 105 derailleur. You will obviously ...

Shimano stamps the rear derailleur model number on the underside/lower plate of the parallelogram. All models for the last several decades.

Definitely one of the models in the Shimano Tourney range. You don't need to know exact model to replace it. You just need to know what specs the replacement derailleur needs. You can look at the derailleur models in the Tourney lines in the Shimano Line-Up pages (you might find you exact model by comparing pictures also). All the specs are pretty self-...

That might be perfectly normal, depending on a few factors. However, the position of the arm isn't really indicative of whether the derailer itself is installed correctly, but rather an indication of how long the chain is. To determine if the chain is the correct length, what you'll need to do is shift onto the biggest cog and check the arm at that position. ...

From your picture, there are a couple of questions. Is the B screw in the correct place. Is the chain the correct length Please watch this video on installing a deraillieur and 1 minute in, they mention the B screw and it's corrct position. Note the two different types of fittings, the direct bolt to the hanger, and the bolt to the tab and then to the ...

It looks a lot like the Shimano TY-300-SGS on the product page, which would be a long cage rear derailleur. However there's no strict guarantee that the current derailleur is the best one for the job, and the definition of short, medium, long changes with time. There are other specs on the product page, like total capacity, low sprocket min/max, etc, which ...

On these Shadow derailleurs, there is a tab that must rest on the bottom lip of the derailleur hangar. (I'll note at this point that you must use the correct hangar for your bike. "Almost" like it or "derailleur has the same angle" when an incorrect hangar is used doesn't cut it. Millimeter differences create big changes in the workings of these things. ...

Nathan is right - the most important thing is that your shifter has enough cable pull to get the derailleur across the cassette. A Shimano 11s derailleur has a 1.4 pull ratio, so to move it 34.8mm you need ~25mm of pull. It should be more pleasant to use with a lower ratio derailleur as the cogs will feel further apart and be easier to trim. It's worth ...

First, take the chain off and shift the derailleur into position and see what happens. If it's still too far away, you can possibly eliminate the short chain (which does look too short) from the equation. Without the chain, you should be able to see what is causing the derailleur to sit at that position. You should be able to find what's preventing the ...

Freewheel 6 or 7 speed wheels typically have no clearance problems there. The issue is likely being caused by rear derailleur hanger misalignment and/or the low limit screw being adjusted too far out. There are many questions about both. Update post-image: The derailleur hanger is bent. Put the shifter in high position and poke a 5mm 3-way wrench or L-...
