You cannot get a higher gear ratio by replacing the cassette. The 11 tooth sprocket is the smallest you can get on a compatible cassette. (Systems with 10 tooth sprockets exist but use a different freehub design).
The issue is that you have 46/30 tooth sub-compact chainrings (I looked up specs here). Which are giving you the low ratios. This is common on ...

Reverse pulses at low voltage probably won't damage the LED, but the COB (chip on board) that gives the flashing modes might not be able to cope with the full reverse voltage.
The problem is that the hub dynamo is more accurately a constant current source, and will supply about 500mA. One common trick is to run two 6V lights in series off a hub dynamo, and ...

CS-HG200 is black, CS-HG201 is silver. Otherwise they are the same.

The only road shifter compatible with a Shimano 10 mountain RD is the Microshift BS-M10.
If you went BS-M10 you could use TRP Hylex brakes to stay hydro.
A number of bikes have been released with those exact components with Shimano 1x10 or 2x10 mountain drivetrains. It works fine if you're amenable to bar ends.
Other than the above, to get 1x10 with brifters ...

Hydraulic brake levers and brake calipers are in general not interchangable.
Shimano MTB 10 speed rear derailleurs do not work with road levers.
You already encountered GRX. It has a 2x10 option, RX400. The rear derailleur is not designed for 1x, however, it has a clutch (Shadow+) and is rated to 46t. I expect it will work well enough in a 1x set up.

Yes, all Shimano 11-speed road cable pull is the same.
The long armed 11-speed FDs like FD-5800, 6800 etc can all be and frequently are replaced with the toggle models, i.e. FD-R8000.

If you're just riding casually, then a simple chainring replacement is probably all you need. You don't have to match the styling, just the Bolthole Circle Diameter (BCD) and number of boltholes. It looks like a 4 bolt pattern, but there are a number of standard sizes (naturally)
Personally I use a 100% printout of the PDF at https://cdn.shopify.com/s/...

You have probably resolved your problem, but others may encounter it, I did.
Number the 6 parts in your photographs from left to right so they corrrespond to the exploded sketch: 8--the nut; 7 and 7a (7 is the mount that enters the bar; 7a is the notched, cylindrical disk that is a separate piece from the mount.); 6--the single tabbed notched washer; 5--...

I replaced the BB on this crankset recently.
I have a spreadsheet here with all Shimano 9/10/11 speed cranksets & BBs

The M523 is the only crankset with these chainrings and bottom bracket. However, the M522 is almost identical with 42/32/24 chainrings & no need ...

I would recommend you to replace not only the chainrings and crankset, but also the bottom bracket.
Octalink is getting rare because it is a big honking design flaw. There are not one but two flaws in it. The first flaw is that it lacks press fit, so the left crank is free to rotate in its splines minutely forwards and backwards. If you rest your weight by ...

The 7700 is higher quality when new than a new Claris derailleur . In particular jockey wheels are sealed bearing and more durable than those on cheap r/ds sold today.

A new rd might be better than a worn out old one with worn out jockey wheels (which you can replace), but ...

FWIW, there is one company that makes a 9-34 11 speed cassette, but that cassette only works on XD hubs. It's unlikely on a stock bike like that but if the wheel set allows you to switch an HG driver for an XD one, you can get one higher gear for about the same price as switching cranks.
Personally, I think 46/30 and 11/32 is an ideal road riding setup if ...

Shimano 8 speed derailleurs and Shimano 8 speed shifters are always compatible. So yes, you can use the 8 speed M310 shifter with your 8 speed derailleur.

Yes, the hub can be at fault. The freewheel mechanism pawls may be sticking in the retracted position, or the pawls and teeth are worn and the pawls are slipping out of the teeth.
You can try to confirm this by having a friend ride behind and to the right of you and watch the cassette area (in an area free of obstructions where you can do this safely). They ...

Thanks to everyone's great help here is the solution that seems like it would work out for me, yrmv (remember this is just a theoretical setup.) Want to stay with as much as OE as I can since just winter setup, 10sp 4700 tiagra levers (same shim 11 sp road cable pull ratios including grx so can't just use any rear derailleur even though is 10sp that gets ...

I have the same problem with Shimano GRX leaver - just found that mineral oil leaked (a spot of leaking oil is visible). bleed screw can not be screwed in (it simply scrolls in the thread). The thread exists in the port by the way.
Thinking now how to fix such problem. For now I have next solutions on my mind:
add mineral oil in the oil tank, put the bleed ...

Would 105 BR-5500 brakes be much of an improvement over what I have?
What could the improvement be?
Lighter weight would mean the brake arms are less stiff, causing flex in the brake system. Thus, you cannot reasonably reduce the weight of the brake arms. Besides, most weight reduction "upgrades" are not worth it, giving only few tens of grams of ...

Problem solved! I realized that the sleeve should not be able to press itself up the spindle like it did in photo #2. I clamped a set of vice grip pliers between the sleeve and the spindle’s flange to stop it from press-fitting itself into the spindle. It came out after that. I will inspect the whole assembly for damage since the hardened steel spindle is ...

LEDs don't like negative voltages. They generally fry at some 3x-5x their normal forward voltage.
Then again, you don't have a bare LED, but a LED and a LED controller and it is the controller that is likely to suffer first. The bad thing is, we don't know much about it.
Another bad thing is that the 6v hub is actually 6v when properly loaded w/ 6V, 3W bulb. ...
