Smooth shifting, performs and looks great.
Installed on a 2006 Fuji NewestI purchased this cassette to rebuild a wheel set on my bike. The Shimano Sora was what came originally on my bike from Fuji, so this was an easy replacement. The cassette came nicely packaged and wrapped from Shimano. So far I have 200 miles on this cassette. The shifting is buttery smooth and the cassette still shines as if it were new about 4 months later. This is a great replacement for my bike and a good buy.

5.0 out of 5 stars Very good cassette
Reviewed in the United States on April 24, 2023
Color: NickelSize: 11-32Verified Purchase
I am a road bike owner\rider that is well on in age. My use of the bike is generally for exercise putting in around 10 miles per session taking about an hour. It takes that long due to being situated on the side of what is loosely defined as a mountain in N.J. The terrain I cover climbs up a few hundred feet (3-5% ??)incline and then descends back down to a low point. So I spend a great deal of time pedaling up the hills and then riding down to the starting point of this effort. Speed ranges from a very low, well under 10 mph, to a high of the low twenties. End result, pretty good conditioning. My original cassette was an 8 speed 12-24 cog set It was good close to ten years ago when I bought the current bike. Now I found that my lowest gear(s) were taxing my knees a bit too much. Could still handle it but it wasn't wise. Therefore, the need for the listed cassette. I opted for the 11-32 device.

Received the cassette, removed the chain, rear wheel and cassette with appropriate tools. If you never did this before there are plenty of online descriptions of how to do the job. Be sure to use appropriate tools as it will make it relatively easy and prevent butchery. Install of the new unit was easy once you pull the old one off. On the other hand you do tangle with the cassette, brakes and your derailleur system. You'll also need to properly adjust your shifters and probably replace your chain with a possible necessary length adjustment. In other words the bike will need some adjustments when you're done with the hardware change. Be ready for all this or think about your LBS for the job.

As for the cassette itself, I just installed it and it seems fine. The SIS is working better than ever plus it matches my terrain of choice. Really like the overall change of gear ratios available. It changed the feel of the bike in a very positive way.

Overall this all was a worthwhile effort at a very reasonable cost.

1.0 out of 5 stars Defective - Mis-manufactured Spline Teeth Mean it Cannot be Installed
Reviewed in the United States on September 23, 2022
Color: NickelSize: 11-34Verified Purchase
I was really excited to try this 11-34 cassette where the 2nd largest cog has 28 teeth making a more reasonable jump from the 34 than the 26 tooth second cog of the CS-HG41-8 and CS-HG31-8 I'd previously been running. Alas, the item I received was defective with the spline teeth incorrectly cut, meaning it could only be wiggled about 2/3 of the way onto any of the three different freewheels I tried to install it on. All of those freewheels easily match my other 8-speed Shimano cassettes, so the problem is definitely with this defective cassette.

5.0 out of 5 stars 8 speed 3x to 1x conversion
Reviewed in the United States on August 3, 2023
Color: NickelSize: 11-34Verified Purchase
Now that I’m in my 50s, I suppose I’m on my way to grumpy old manhood because I have become increasingly annoyed with shifting chainrings. I live in a very hilly area near a river and its winding feeder creeks so front shifting is mandatory. Months ago I came to the realization of just how much having to constantly coordinate front and rear shifting was interrupting just being lost in the pleasure of gliding through scenic spaces. I bought a new 1x11 gravel bike in May and riding it has been so liberating that I decided to convert my beloved ‘08 Trek 7.3 FX 8 speed to distraction free 1x riding.

Off came the front shift cable, front derailleur, big ring, granny ring and 11-30 cassette. On went an 11-40 and Wolf Tooth RoadLink. First ride exhibited some sobering outboard chain drops. Lesson learned: front derailleurs do not only shift, but also serve as uncredited chain keepers. Refusing to reinstall it lead to Experiment One: remounting the big ring to act as a chain drop blocker. All was well until the 30 mile mark: I’ll be darned if that pesky chain didn’t climb onto the big ring sans a front derailleur! Manually repositioned the chain back on the 38 ring, wiped my oily fingers in the grass and off I went.

Over the next few days, I contemplated flipping the big ring so that the ramps and pins faced outboard in hopes of precluding any future magic tricks. Meanwhile, on Amazon I stumbled across the Ganopper 36 38 40 42 Tooth 104 BCD Chainring Guard which looked infinitely more appealing that toothy big ring. Initial installation without the provided spacers exhibited chain rub on the Ganopper while on the 11T rear sprocket. This promptly disappeared upon installing the spacers. Following were repeated attempts while clamped into the repair stand to induce outboard chain drop by dumping the gears as fast as I could. Couldn’t do it. I am, nonetheless baffled: the chain never seems to actually make contact with the Ganopper. Huh? It’s as if the darn thing MAGNETICALLY repulses the chain … (scratching head) …

Anyway, I’m going to ride this hacked set up for a month or two. By hacked, I refer to keeping the original, albeit stripped-down crankset vs installing a new dedicated 1x variant. Down the road, I may experiment with a narrow wide chainring and a 9 speed chain (the internal dimensions of which will mate more soundly with the NW chainring). The 9 speed chain should get along with the 8 speed sprockets although shifting may not be quite as crisp. FYI: 5 - 8 speed chains have 3/32 inch (equivalent to 12/128 inch) internal widths while 9 - 12 speed chains have 11/128 inch internal widths.

As I anticipated, the changes in cadence with the 11-40 cassette were stout to say the least, but it was a compromise that I swallowed in exchange for decent 40T climbing capability. Well, the cadence jolts got old real quick. However, such a cassette may be just the ticket for more casual rides in hilly areas. As for me, while the new Jamis Renegade S1 is assigned all the long rides with long climbs, the FX stays close to home on fast, flatter circuits, especially when rain is threatening. So, on went this $15 Shimano Sora 11-34 cassette. At least the $40 11-40 experiment wasn't an expensive one. It will live in my parts bin for now.

The first 11-34 ride this evening was a blast. There is noticeably less cadence discontinuity in comparison to the 11-40 upshift grinds and downshift spinouts. The 38 ring /34 sprocket combo proved sufficient on the brief climbs nearby. As i was riding fast anyway, it was actually further exhilarating sprint grinding up stubby little hills.

Among the various pleasures inherent in cycling, breathing new life into a tired old bike is high on the list. The FX will no longer have to watch from the corner of the garage while its Gravel 1x stablemate comes and goes. Welcome back to regular rotation old friend!

Update: Fast, flattish circuits demand smaller cadence changes. Off the FX and into the parts bin went this 11-34 cassette and back on went the original 11-30. Also, swapped out the original 38T middle chainring with a Raceface 38T narrow wide ring and swapped the chain from an 8 to a 9 speed one. Rode hard for a little over an hour this evening with decent shifting and no dropped chains nor cadence issues. If you are contemplating a 1x conversion, I would recommend that the tooth count of the largest cassette sprocket be no more than 4 times the drivetrain speed count: 7 speed /28T max, 8 speed /32T, 9/36, 10/40, 11/44, 12/48. Just HOW many gears are 1x’s going to have 20 years from now?!

Le rapport qualité/prix est bon mais j’aurais aimé un alignement un peu plus précis. Je l’ai fait vérifier par une boutique spécialisée et ont m’a dit qu’il n’y aurait pas de problème à l’utilisation. J’ai acheté cette cassette pour ma base d’entrainement. Donc c’est une cassette secondaire.
