Perfect fit, workshops better than whatever cheap gear came on my schwinn

Love this cassette, it gives the perfromance I need for going UP the mountains and going DOWN the mountains...

I didn't know my original equipment cassette still on my bike and covered in black oil had HG-50 engraved on the lock-ring, but I cleaned it off I see that now. I believe this HG-31 may work perfectly fine on my bike, and the difference between this and my HG-50 may be just cosmetic (my HG-50 is sort of a gold color vs. the black HG-31), but I may go with the HG-50 anyway, as I see it is still available on Amazon. That way, my drivetrain, which has been working perfectly up 'til recently, remains as it was from the factory.OH - I have seen some comments on Amazon for other Shimano cassettes about a "missing rivet" on the back of the cassette, with the assumption that means the cassette is "defective". I have looked at two Shimano cassettes (HG-31, HG-51) and a few pictures off various websites and every Shimano cassette I see has only two rivets on the back with what looks like a hole for the alleged mysterious third "missing rivet". But a few comments on the net seem to say the two rivets you DO see on the backs of the cassettes are just for aligning the cogs during cassette assembly and no third rivet is needed. Do your own research if the "missing rivet" theory is a concern.

Replacement cassette. Exactly what I wanted.

si adatta bene

J’ai acheté ce modèle en ligne après une mauvaise expérience de remplacement chez un réparateur vélo avec une durée de vie très limitée, alors que le réparateur avait insisté pour remplacer également la chaîne pour éviter les problèmes liés à la différence d’usure. Pas de problème à signaler avec ce modèle qui fonctionne très bien depuis des lustres, sans remplacement de la chaîne. La seule contrainte est d’avoir le bon outil pour procéder au remplacement.

I put this in my bike a few miles back and it has been just great overall id highly recomend this cassette if it fits your needs.when I bought a new rear wheel is had to find a cassette for it and I came across this 1 through some research online and to my suprise it was exactly the same as the set on my specialized roll sport! Nice upgrade for sure and well worth the money.

It fits well on my IGO E-bike, and I'm happy with the performance so far. Time will tell if it lasts as long as the original. It came with all the parts and in a timely manner, which I needed.

Genau wie geschrieben, gute Qualität und schnelle Lieferung.

This was inexpensive and works nicely. Easy to install and seems durable.

I replaced my original cog set as it was getting old. This set looks great, easy to install with the correct cog wrench, and it captures my chain so perfectly that ishave zero slop. My bike is extremely responsive when i step on my pedal. I feel like meand my bike are now one.

Quick Notes:-Good quality cassette fit on Shimano hub without issue-Easy to install as long as you have a Shimano freewheel tool.-Shift to higher gears (higher toothed gears) very smoothly.-Tends to slam (skips down instead of rolling onto the cog) into lower gears even with a new Acera derailleur-Can put a good amount of force onto the cassette threw the crankset.-If you are heavier or plan on putting a lot of sudden force onto this cassette the even a new chain will skip on it.-I would only recommend this cassette to casual rides or commuters as an economy option since they more than likely won’t have to put a lot of force into the cassette or change gears a lot.-If you off road or use your bike for training this cassette is not for you. I would recommend the new cassette I have had for a few weeks that doesn’t have any of the above mentioned issues and is still fairly cheap. (Shimano HG51 8-Speed Cassette).-The photos are of the cassette after a little over a month of useFull Review:I purchased this cassette over a month ago when I stripped the teeth off of my 11 and 13 tooth cog on my old cassette. Installation was very easy you will need a Shimano freewheel tool I have (Park Tool FR-1 Freewheel Remover for Shimano Freewheels) and an old chain. You don’t need a chain whip it does make things easier but I’ve removed 3 different cassettes just using an old chain I had laying around to hold the old cassette and prevent it from moving and you don’t need it installing the new cassette. If you don’t know how to replace a cassette I strongly suggest you head over to YouTube and look it up its very easy to do as long as you do it right. Righting with this new cassette my first impressions were great I didn’t feel any loss of power from my crank-set to the rear cassette and wheel. That only lasted when I was riding casually though as soon as I put a lot of power threw my cranks when climbing a hill of when going off road the chain started skipping on the cassette. Now I’m not mad at the cassette of Shimano for this and I figured this would happen as this is the cheapest cassette Shimano makes and isn’t really suited for training or going off road. But I figured I would give it a try since it was so cheap and I needed a new cassette not that I wouldn’t have to send back. So I used this cassette for over a month while I looked at new cassettes and tried to figure out want I wanted and needed and still get it at a low price. I eventually went with (Shimano HG51 8-Speed Cassette) that I’ve had for a week now and absolutely love had done training and gone off road with it every day and have had no issues. So I would recommend to almost everyone to spend the extra ten bucks and get that as its much higher quality. That is unless you will only be using this cassette on a casual bike or a commuting bike and just need the cheapest thing out there because this isn’t a bad cassette you just can’t put a lot of power into it.--*If you have any questions please leave a comment and I will try and respond as soon as I can, but I have a job and things to do so please don't expect a response immediately.*

This is Shimano's 'low end' 8 speed cassette. That basically translates into it being heavier and not as pretty to look at as their higher tier parts. I installed this on my 'utility / commuter bike', for which aesthetics and (low) weight are not high up on my list of priorities. What is important to me is performance and durability, which this part will certainly give you. There are various speciality tools that will work for installation. I used a chain whip and cassette lockring remover, which are also nice tools to have on hand if you ever need to replace a broken spoke. Shimano is known for delivering very good performance throughout their range of parts, even on the low end. So while this cassette may not win awards for it's use of exotic materials, light weight, or 'bling factor', it will help you achieve positive and crisp shifting at a low price point and is likewise built for durability. To me, that makes it a winner.Great for:commuter bikes (riding to work, ect)utility bikes (picking up groceries, running errands, getting around town)casual (pleasure) riding, or riding for fitness.Not recommended for:racing or competitive riding (triathlons, duathlons, time trials, road racing)'blinging' out your ride
