Description

Custom Length MicroSpline Aluminum Spacer (Narrow)This is a custom length aluminum MicroSpline spacer. No need to stack multiple sizes of spacers on top of one another, as this could replace those stacks with 2 slick pieces. Our cogs are 8. 4mm wide, so the total length of both spacers and the cog should be slightly more than the length of the hub body to allow for adequate preloading. Each spacer could be different lengths, allowing you to position your cog wherever you'd like on the hub to dial

This is a custom length aluminum MicroSpline spacer.  No need to stack multiple sizes of spacers on top of one another, as this could replace those stacks with 2 slick pieces. Our cogs are 8.4mm wide, so the total length of both spacers and the cog should be slightly more than the length of the hub body to allow for adequate preloading.  Each spacer could be different lengths, allowing you to position your cog wherever you'd like on the hub to dial your chain line down to a tenth of a millimeter!

(Note that the narrow and wide are the same thing; the shopping cart can only handle 100 variants, and this is a simple way to allow ordering a wider range)

If using our lockring, use this method to determine spacer widths:

1. Measure the spline body that the spacers will bottom on.  My MicroSpline freehub measures 26.2mm from bottom flange to tallest point.

2. Our cogs are 8.4mm wide, so 26.2mm-8.4mm is 17.8mm for the pair of spacers.  For a centered chainline, simply divide by 2.  It's 17.8mm/2 = 8.9mm per spacer in this case.

Our lockring needs an extra 3.0mm spacing from the freehub because the threads won't go completely to the square shoulder due to tool width and lathe deceleration distance.  This means the outer spacer gets 3mm added to its width.  In this case it would be 8.9mm+ 3.0mm = 11.9mm.

3. If you want your ideal chainline to vary from center of the freehub, you simply add that distance to one and subtract from the other.  If you wanted to be 2mm more inboard in this example, the inner spacer would then be 6.9mm and the outer one 13.9mm.

Torque spec should be 40Nm.

Simple and Straightforward Wrist Rest
Size: 60% Compact
There's not much to write home about here other than it suits the purposes I purchased it for. This accompanies my K629-RGB Redragon keyboard. It lines up pretty well with the keyboard, and the rest itself makes a nice incline between my desk surface and the keyboard. The padding isn't too plush and is pretty good at providing wrist support. It's also been very good at holding its shape despite the pressure that my wrists have put in the same spot over the last few months; the padding is even across the entire wrist rest as a result. I've noticed that my hand doesn't cramp as much when typing for long periods of time with this rest, so it's doing exactly what I would expect for the ergonomics of my keyboard. One downside is that it's prone to develop sweat marks where you rest your palms. It can't really be wiped away, given that it gets absorbed over time. I would say that if you are concerned with the appearance of the product, you may want to look into a plastic rest instead. I personally don't find this to be much of an issue since the pad is black, and you can only see the marks at certain angles, but I can understand if that's a dealbreaker for some. Otherwise, the rest of the pad is easily cleaned. I usually use a handheld vacuum to tackle dust and crumbs that stick onto the sides and bottom of the pad. Overall, I would recommend this to anyone who has a compact keyboard without a built-in hand rest. The pad is perfectly sized for my needs and provides the support that I need for my work. If you're hesitant about dealing with a product that may stain, look into plastic wrist rests instead.

comfy, not rigid and would recommend
Size: 60% Compact
it has some slip resistance though I see it slightly sliding every so often, it's obviously easy to install just place it there ha-ha, sturdy and comfortable. good support, I settled for this because I got it for 5 bucks not bad at all, it's about a half inch smaller than my keyboard (it says the size, so I knew that prior to purchasing so its sizing is correct as stated, a good thing) I should mention my desk is hard wood with some scratches in it so some of my other things slide too so I can't say its slip resistance is bad even with it slightly shifting every so often I'm sure it will be better for your desks too. here its barley slides so I'm sure it will stick in place like glue on your desks (aka wont slide you can easily move it if you wanted). I looked at the reviews saying this thing was rigid or not enough cushion, I feel like it's not too little not too much, not rigid, don't know what they are talking about, anyways I would definitely recommend.

Feels nice and looks great
Size: 80% Tenkeyless, Size: 80% Tenkeyless
I bought this wrist rest in like new condition for $6 and I will say it’s 100% worth MSRP at $15-20. The weight is nice, it doesn’t slip on my mousepad. It’s very comfortable to rest my palms and wrist on. The sizing pairs well with my 80% keyboard. It functions as it should. I use this at a stand up desk on an industrial shop floor to help put my wrist at a better angle and it works perfect.

Decent; does the job
Size: 100% Standard
Cushion feels very porous and thin. I suppose you can call it memory foam because it basically sunk where I usually rest my wrist and has not returned to its original shape (lol). The small rubber pads on the underside help a bit but slip resistance would probably be better if they covered a larger area. Overall, it's not bad for sub $20 full size kb wrist rest.

Is does the job, love it.
Size: 60% Compact
Is really comfy, it does the job, you can't go wrong with it. Just buy it if you have a 75% keyboard or less because is not long. For me is not a problem.
