Altus Shimano Cassette Sprocket CS-HG31

Easy to install, shifts smoothly, heavier construction than my factory cassette. Was a direct replacement on my Scwhinn Axum 29 in wheel.

I purchased it for my vintage 2000 Univega Alpina 500 24 speed MTB. Which was originally equipped with a 8-speed 11-30T cassette sprocket. Also purchased the Oumers Bike Cassette Removal Tool Kit so i can tightened the lock ring. It worked perfectly, and I didn't have to readjust the derailleurs. I'm very happy with the purchase.

This is the cassette of choice for most of my bikes. Quality shifting, long-lasting and dirt cheap. It may weigh a few ounces more, but not significant for your daily rider. I only wished Shimano produced these at a 12-36 or even 13-40, but it would eat away at the huge profits they make on the higher-end cassettes.

This was a drop in replacement on an Ozark Trail G.1 Explorer Flat Bar. The generic stock "clone" cassette caused some chain skipping/slipping in 8th gear when pedaling hard-ish. This cassette fixed that and even seems to shift a bit smoother. I saw comments about only having two rivets in the back where it appears there should be three. Mine only had two and works perfectly. I think that is by design, and not a goof up or defect.

This was the factory cassette on a Quiet Kat Warrior hunting e-bike. I had allowed my old chain to stretch WAY too much and the new chain was skipping on my lower gears after I replaced it. I decided to replace the cassette and chainring. Replacing the cassette was incredibly easy (plenty of how-to videos online). I bought the $10 Park Tool Shimano cassette tool, but I did manage to actually remove the old cassette with the "needle nose pliers method" that I found online before the tool arrived. I also did not have a chain whip? tool and simply used the old chain clamped with vice grips to keep the cassette from spinning. A quick overview of the needle nose method: 1. Remove the rear wheel and lay flat on the floor with the cassette on top. 2. Using a chain whip, pipe wrench, large channel locks, etc..., prevent the hub from spinning. 3. Insert small needle nose pliers into the hub... pull out on the handle to spread the needle nose part as wide as possible inside the hub. Try to get the needle nose into 2 of the slots that are in the center, across from each other. 4. While applying pressure to spread the tips of the needle nose, rotate the needle nose pliers counter clockwise. If it comes off, GREAT! If not, you may need the cassette tool. With the cassette tool, I still found that I did not need the chain whip. I held the cassette still with a towel and used an impact on the cassette tool. It broke loose quickly this way on all 3 of my bikes. Last thing: I did clean the freehub before reassembly, and lubed all of the gears on the cassette before I finished the install. While I was in there, I also cleaned the derailleur cogs. I am very happy with this item!

Can we ask for the price Shimano?

Works great, bit extra range. Any larger cog and it would start shifting funny and potentially need a hanger extender.

I had been experiencing some chain slip while cycling on a mostly flat limestone trail. Spraying some dry lube on it seemed to reduce the frequency of the slip however I wanted to totally eliminate it so I first purchased a new chain and tested it out on the hilly asphalt roads near my house. The new chain caused it to slip even more than the old. I got some online advice which suggested changing the cassette so I put the old chain back on (so I could continue using the bicycle) and ordered the exact HG11-34 model I have on my 2018 Giant bicycle. Anyways it arrived today and 15 minutes after it was delivered I had installed it and put the new chain back and all slippage was totally eliminated when riding on the asphalt roads again. After this I did a 32 mile ride on the limestone trail with no chain slip and the shifting feels great.

This one is slightly higher in quality and price than the one I'm replacing.But it definitely makes it better
