g502 mouse wheel mod.

[dizz_ee]

First off, all credit should go to Sidd, who's guide I have linked 

 

I recently bought a g502 to replace my g700. Quickly realised the mouse wheel sucked especially when in free spin mode, it is unbalanced so when you stop it rolling it would roll back and scroll up until the heaviest part rested at the bottom.

 So decided to search google to see if anyone had any solutions, some one had replaced the g502 wheel with a g500. So I opened up my g700, and it is exactly the same setup as the g502 except the actual wheel in the g700 is probably the best scroll wheel ive used(g502 is cheap shit).

Here is the link to the original guide:

This was the only negative in linus' review of the mouse so I thought I would share.

 

and a pic of mine with the g700 wheel already installed in the g502:

I love my 502 wheel

do you have the problem in free spin mode, where it rolls back by itself once you stop it?

"Some" drilling and your wheel is balanced))) Ten years passed, but problem is still here. Unbelievable!

I like it. It's creative. To be honest though, we have 3 G502s here in the house. Never use the free spin mode, but I flipped them over real quick and checked, and none of them have an issue. Maybe they are old enough they just don't "free spin" enough anymore.

Super weird I just tried it, I don't really like it, but I get it, it's for the "doomscrollers"

 

However it did not skip or move or role after being stopped. not. at. all.

Is this mouse from 2015? Because none of my g502 heroes shows the described behavior.

 No rolling back, skipping, whatever. None.

 

 

Maybe your desk needs fixing?  ;>

Wait, is this a "none hero"? Does that exist? Then I suppose the hero came later and it *did* indeed change. :x

So as one of those "huh" kinda moments.  I have a G502 Lightspeed mouse that I bought back in 2021.  It has a hollow wheel, not a solid core one like the original photo's from the thread and the other wheel swap post. My balance seems really good with it and doesn't seem to ever drift off.  My previous mouse was the G700 and agree it has a great wheel as well.  They may have fixed/upgraded the G502 at some point but I only have one of them so not sure.
