The current RD-5700 is a road 10 speed derailleur. Shimano road 10 speed rear derailleurs (except Tiagra RD-4700*) share the same actuation ratio as all Shimano rear derailleurs marketed as 7, 8, or 9 ...

Are equivalent chainring/cog combinations indistinguishable?
50:19 has less drivetrain friction because the chain doesn't have to bend around such tight angles. This means it will be slightly easier to maintain the same speed in that gear combination.
This ...

Why does my rear derailleur's indexing work for either the high or the low gears, but not both?
I have had a think about the last few times I've "snapped a cable" in the handlebar's gears selector. Thinking about each of the last 3 or 4 times this has happened to me, for the preceding ...

Any history on Viscount bicycles?
Had one of these in the mid seventies. Went round Europe for three years, no problems apart from a pedal that snapped off. The pedal spindle is undercut for the needle bearings, which weakens it. ...

What liquid should I use in an ultrasonic cleaner?
I've used a laboratory ultrasonic bath for bike parts. That's designed specifically for use with only plain water directly in the bath, and I wouldn't want to contaminate it anyway.
Any solvents or ...

What liquid should I use in an ultrasonic cleaner?
In my tiny 0.8L cleaner, I use water with a splash of turps or similar solvent. I also pre-clean the item with a rag or paper towel or pick/scraper.
I personally do not, but you can reuse the liquid, ...

What liquid should I use in an ultrasonic cleaner?
There's a range of degreasers that will work in there from the more potent like mineral spirits, to dedicated cycling degreasing products (expensive!), to washing up liquid.
I've also seen a nice ...

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?
Shimano used to make a 10 speed 40/28 crankset: https://bike.shimano.com/en-EU/product/component/deorext-m780/FC-M785.html
This would probably be your best alternative for a direct replacement, ...

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?
Other answers have already answered the question "directly", my answer will be about the underlying problem, which is about the gears not being hard enough.

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?
You can add a few teeth, but not enough to make a significant difference. The photo shows that the front derailleur can be moved upwards by about 0.7cm, which would be enough to add 3 teeth. The ...

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?
Maybe
It’s a 96mm BCD chainring so you might be able to purchase a compatible part e.g Shimano XT M782 40t 96mm 10-Speed. A third party 96mm ring will also be fine. You will be looking for 2x10 96BCD ...

How can I find out the number of teeth on each cog for cassettes and chain rings?
Usually a given gear count and range has a certain defined sprocket set.
For example, 10sp 11-34 is 11-13-15-17-19-21-23-26-30-34.
Also 8sp 11-30 is 11-13-15-17-20-23-26-30.
Those are generally ...

How can I find out the number of teeth on each cog for cassettes and chain rings?
There are no fixed industry standards and cassettes with the same upper and lower sprockets, but differing in between, do indeed exist.
Eg., for 9-speed

How can I find out the number of teeth on each cog for cassettes and chain rings?
There aren’t that many models of cassette out there in the market. I don’t think it would take much longer than a few hours to just search up every model and manually enter their tooth counts into a ...

How can I find out the number of teeth on each cog for cassettes and chain rings?
You're right - you need more information to be certain.
However you might be able to get the cassette's model number, which can be tracked back to an exact tooth-count per gear.
You could also write a ...

My bike's gears won't shift properly or at all
Per the comment thread, the cables are quite rusty. That would surely cause the condition you described and showed in your video.
If the cables are that bad, it really is worth having them replaced by ...
