SHIMANO Cassette Sprocket, Cs-Hg50 8-S, Ni-Plated, 11-13-15-18-21

Exelente

I use it for long distancing with a heavy loaded bicycle and it works great.I have driven more than 1200 miles by this part up to now.I sometimes shift from 28 to 34 in the middle of a steep road (front chainring 22t), and I just feel that the pedal becomes softer..!

Installed on a Wahoo Kickr 4, no issues.

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?!

I normally get 3 chain replacements before having to replace this cassette. 2000 miles per chain. I prefer SRAM PC-850/870 chains, as they seem to put less wear on the cassette. **IMPORTANT INFO RIGHT HERE** pertaining to comments about "out of round" gears. You`ll notice Shimano cassettes have 2 small rivets on the rear, hardly noticeable. If you place the cassette on the hub without grinding them down smooth, it won`t sit flat. 8 speed cassettes usually require a 1mm spacer to use on modern 9-10-11 speed hubs/rims. I find grinding 2 notches in the spacer with a Dremel tool to accommodate the rivets is the best solution. This way you`ll only need to do it once, not every cassette change.

MTB trail riding this 11-34t cassette 5 years now. Have a 1X8 29er, and it doesn't miss a shift. Paired with a narrow/wide chainring to keep the chain from popping off over washboard trails...(its a hardtail, rigid front). For my height/weight/strength, a 30t chainring climbs really well, but may try a 28t. Tried an off-brand 11-40t, and found it VERY heavy, and shifted poorly, compared to this Shimano.

Nice quality cassette cog for my Carbon Fiber road wheelset (ICAN 38mm Cyclocross Built wheels) to have it work on my Motobecane Fantom Cross Trail.My bike came with a nice, wide aluminum wheelset, and they now wear 35c Continental PureGrip Tubeless tires.BUT, my Carbon road wheelset is more suited to road use, with narrower 28c Continental Ultra Sport road tires.This wheelset had a Tiagra Shimano 10 speed cassette on it (from use with my Giant road bike), and I wanted to run this wheelset on the Motobecane Fantom Cross Trail, which is an 8 speed bike.Enter this cassette, and I just popped it on the Carbon ICAN Wheelset, 1 thin spacer behind it, and viola !I've now got 2 wheelset options for my Motobecane bike.So, I can fit one wheelset for Gravel / Trail use, and the other when I'm going to ride mostly Road, or for a modest Road Race or T-Shirt Ride.

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.

Going on a comfort bike build.
