Shifter requiring to press the lever fully without resistance before engaging
I've seen this happen on slightly older thumb shifters. What happened in my case was that the grease inside the shifter had gone stiff, so the ratchet mechanism didn't spring back promptly. I still ...

Could I use a Shimano GRX RX400 10-speed shifter with a Shimano Dura-Ace 7900 10-speed rear derailleur?
The GRX ST-RX400 is compatible with the Tiagra RD-4700, which means it is using the 11-speed cable pull, making it incompatible with 10-speed road RD such as the Dura-Ace RD-7900.
Here is an excerpt ...

Upgrading from 42-34-24 T crankset to Shimano 48-38-28T?
As mentioned in the comments - chain length will likely need to be increased, but new chain rings I would be installing new chain and cassette anyway. Check rear derailleur capacity is not being ...

Upgrading my shimano road groupset, compatibility issues
There's no permutation of this where you only change the shifters and rear derailleur.
The cassette has to go no matter what, because you have 10-speed and R7000 is 11. Unless you have an 11-speed ...

Upgrading my shimano road groupset, compatibility issues
According to Shimano's compatibility chart, the R6700 groupset is only compatible with 105 R5700 and Tiagra 4600. In other words, you already have the best groupset for this "system". To ...

Front derailleur clamp/hanger for Rivendell frame
That is a very weird situation. Sometimes thick finish can inflate the tube OD, but not typically by that much. It's curious what the seat tube used is. Seat tubes are typically built to be seat tubes,...

105 R7000 chain rubbing bigger sprocket when pedaling backwards
It's pretty normal to get minor chain jitter and even hopping between sprockets if you pedal backwards at the extremes (highest/lowest gears). The answer is probably just "don't do that". If ...

Can a Mavic Freewheel Body (HG11 B9) fit into a 28"Mavic Ksyrium Elite Wheel (that already has a Shimano freehub)?
The question is hard to answer without knowing the exact version of the wheel.
Mavic has a good technical manual website, that can help to check compatibilities:

Want to change Shimano CS-5800 and FC-RS500. What are the newer models?
I misread the question when responding at first. The comment clarifies that the OP feels both the chainring and cassette are worn.
Yes, the R7000 or even the R8000 cassette can be used without issue (...

What is the quantity and size of the ball bearings in Shimano M785 freehub?
Apparently the freehub body on that hub is FH-M770, though several others fit as well. I've worked on a couple of models of freehubs from that list and they used 25×1/8" balls each side. I've ...

Bottom bracket to replace a Shimano BB-UN100?
With Shimano square taper bottom brackets, the things to look for are the size of shell (68 or 73mm) and the axle length (In this case 122.5). A third important parameter is the threading size and ...

Can I use a shimano 105 11spd derailleur and r7020 shifters with a 9 spd cassette?
11-speed shifters almost certainly won't work with a 9-speed cassette. Aside from the obvious issue that you'd have two extra clicks on the shifter (which I suppose you could opt not to use, all other ...

Tiagra 4600 trigger shifters, 10-speed 105 RD-5701-GS derailleur and 11-32 cassette compatible?
Yes, the RD-5701-GS would work for a 11-32 cassette if you stick to a double crankset. If you ever change for a triple crankset, the maximum low sprocket size with the GS is 30T.
See the RD-5701 ...

Identify a replacement shimano rear derailleur
Pretty much all 6-9 speed Shimano derailleurs should be compatible. The pull ratio of all of them is the same.
The main concern is that the derailleur "capacity" is enough to take in the ...
