Shimano HG81 SLX 10 Speed Cassette

Shimano SLX HG81 10-Speed Cassette
The Shimano SLX HG81 10-speed mountain bike cassette is lightweight, rigid and designed to deliver the precise, responsive shifting performance and worry-free dependability that off-road riders demand.
  • Four largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
  • Sprockets are milled and drilled to reduce weight while retaining rigidity
  • Special computer-designed tooth configuration with contoured shift gates for precise, smooth shifting, even under load
  • Close-ratio gearing lets you better control cadence for improved energy transfer efficiency
  • Compatible with super-narrow 10-speed Hyper Glide chains only

Great 10-speed cassette, especially for the price
I got this to use in converting an older frame to a 10-speed chain setup, and this cassette exceeded my expectations. Its gearing, weight, and smooth-shifting make it feel like it should cost more than the $36 price. I used it in combination with Deore shifters and rear derailleur and a HG54 chain. No complaints.

Good product
Replaced my HG50 with this one. Smoother shifting was immediately noticed, and the cassette looks nice. No idea on durability yet.

Can't Beat The Value!
The SLX cassette is only a few grams more than the XT model as it keeps the big gears that count on a spider. While the XT model isn't much more, I doubt you could possibly notice the difference so you can't go wrong with this. It shifts as good as the XT and you know it will last.

Smooth shifting
Replacement for an XT cassette for a set of wheels recently downgraded to "training". No perceivable difference in shifting smoothness. Weight
on my scales is 367 g comparing to 340g for the xt.

Great value for a solid piece of gear. Not the lightest but works great

Solid construction with the 2 spacers for 9 and 10 speed hub
A bit heavy but you get a wide spider for the high torque gears. You also gain a tooth at the right place go those that ride at 15-18 mph

Great Cassette. Smooth shifting
It was time to replace my worn out SLX cassette since I was starting to get chain skip and some shark toothing. Replacment was easy and shifting is now way smooth.

Will this work on a Zee rear mech?
CarterLindblom on Feb 25, 2017
BEST ANSWER: Depends if you have the FR or DH version. I have the FR Zee mech with the exact cassette and it works perfectly.
How do i know how many teeth i need?
A shopper on Jan 14, 2017
BEST ANSWER: It really depends on riding style and what you have up front. 1 or 2 chainrings? If it's a mountain bike I would stick with the standard 11-36 and you'll be fine most anywhere but sustained climbs may hurt if you only have 1 chainring up front. If you have 2 then you will.be perfectly fine. If you're wanting to go to a 1x then I suggest looking into sunrace 11-42 cassettes for 10 speed.
Is it specifically for 9 speed or can I use 10 speed cassette as well? How do I know it this fits my hub and wheel?

Shimano 9 Speed HG Freehub Body
Shimano 9 Speed HG Freehub Body
BEST ANSWER: All 9 spd freehubs are 10spd compatible. Most Shimano freehubs are identical in that they have the same base design. They differ in spacers and seals. If you are handy you should be able to get this freehub to work.
My bike is an older Cannondale Gemini 1000 (lefty) with 9 speed Shimano XT components, would this fit the hub? I believe I have Cannondale hubs. I am converting the derailleurs and shifters to 10 speed as well. Thank you!
Jack L on Jan 17, 2017
BEST ANSWER: Yes it will fit...9/10 spd will fit your freehub. I had a 9 speed and this fit right on, no issues. 11 speed will not. Legit cassette for the price.

BEST ANSWER: This will work for 10 Speed Cassettes
How do I know if I could fit this on my hub ? Is there any way to know this without removing the wheel?
A shopper on Apr 24, 2017
BEST ANSWER: If your rear cassette has 8,9,10 or speeds (different cogs on the cluster), you can pretty much guarantee you can fit this on your hub.
I am converting from 3x7 to 10 speed. How shud I check if this fits my freehub body? Do I even need to change it?
A shopper on Apr 22, 2017
BEST ANSWER: 7 speed freehub bodies unfortunately do not fit 10 speed cassettes. 8/9/10 speed do all use the same freehub, but 7 speed cassette freehub bodies are a little too short.
