BOLANY 8-9-10-11-12 Speed Cassette 11-32T 11-36T 11-40T 11-42T 11-46T 11-50T 11-52T Wide Ratio MTB Bicycle Part Freewheel Sprocket (9 Speed 11-46T)

I'll start with what why I purchased the Bolany 9 speed 11-50T cassett. I own a Quickie Shark Hand Cycle. In it stock trim its a good all around entry bike. For me the stock Triple ring front crank set 44-32-21T and 9 speed 11-34T cassett left me with a need for a broader ratios due to hills both down and up them. My first change was the down hill problem, could not pedal fast enough to add speed down hill. Resolved that with a 46T Front big ring. For the up hill anything over 7% grade for even a short climb required frequent stops due the arms giving up. So after some math I figured I needed to jump from 34T to at least 46T and more if I was going to go up steeper hills. So when I came across the Bolany 11-50T it got the eyebrow raise followed by the Ooh! And a very inexpensive price when you consider it came with the derailer extension.I checked with my local bike shop since they are familier with my bike to see if they thought it would be plausible to do the swap. My bike needed all new cables/chain anyway so I figured if they said yes I would order it and let them swap it incase it needed some attention I could not give it. Andthey said yes.So I ordered it. Only bummer here is the stated shipping time of 4 weeks. I was relieved when it arrived in 10 days. It arrived with the product box wrapped in foam and celaphane. The product box was slightly squished but not alarmingly so.Installation had one two challenges mostely due to the bike itself and my setup not the product itself. 1) my frome needed about 1/2mill grinding to allow the extension fit flush and secure. 2) Because the bike needs a real long chain to begin with and my 46T big ring, the 50T needs a lot of chain. This lead to a very slack chain when in the 21T front ring and in the 11-24T on the cassett. Its will shift to those but it will literally slide overitself and the shift are slow. Again this is not the products fault its just the derailers dog leg was not ment to handle such a large spread of ratios. All 11-50 work perfectly on the middle 32T and 46T front rings. So I live with it and it really is not a problem since the only time I'm in my small ring I'm looking for those big ones.My impressions after a month of riding. I am very happy with the purchase. I do 7% grades now without stopping or exploding my heart. Yes at a slow speed but doing them with a cadence in the mid 80s. Shifting when in my big or middle ring on cranks is general smooth, although sometimes take some time (again cost of the long chain on my bike). The slack chain on the Small crank ring in the smaller casasett gears has not proven to be a inconvenience, I usually swith to my middle front before getting down to those for a better cadence. Speaking of cadence, I was surprised that in middle ring that the spacing between gears 80% of the time finds the sweat spot better often only needing only one shift opposed to 2.I would recommend this for anyone looking for wider ratio spread.

So far the new cassette working OK. Have not yet put that many miles on it. Installation went OK. Adjustment after installation went OK. Shifting is pretty clean. I also installed new chain. Buyers need to remember that a longer chain than original equipment may be required. Probably got 80 miles on cassette and it and chain are operating well.

I buy this on 17 june 2029 and receive on Aug 2020. In the picture you can see that the first mesh one teeth is incomplete...I will use it like that...I don't think do business here aging.

I am converting a 24 speed bicycle into a 10 speed motorized bicycle, and this cassette is just the ticket to get it done. Since my bike will have a 4.4 HP two stroke chainsaw engine powering it, I am more interested in durability than lighter weight, so I was tickled to death to find this 10 speed cassette with such a wide ratio of cogs made out of steel and at a price I can live with. The only hiccup is that this ships from the east and it does take a while. I waited over 3 weeks to get this, but the wait was worth it since I can't find anything else of this quality in this price range.

Bought this to replace my XT cassette, after going through two XT's, I decided to find a replacement that was made of steel. Sure its heavier but it will no doubt last a lot longer. Shifts feel more solid and confident, the smaller gears have more material on them than the XT which will no doubt bring longer serviceability.

Perfect combo for a 1x9 conversion! Easy replacement and comes with the hanger extension

I wasn't able to make this product work and bought a "Goatlink" to try and fix my fitment issue. That didn't work either. Eventually I was able to make this product work by installing the included derailer attachment backwards and on the inside of the dropouts rather than the outside where you would naturally think it would fit.Having a 52 tooth granny gear has been fantastic for those tough hill climbs laden with camp gear.

This is a light cassete that works well. Although you need to be very careful with the assembling. The screws that hold the spokes together can be loose and damage your hub. That happened to me and I had my DT-Swiss Hub damaged by one of these screws. I recommend double-checking the tightness of those screws and use lock tight bond to avoid them getting loose with time. Otherwise, this is a good part (and much cheaper than the Shimano or SRAM similars).

Estupendo. Tengo la versión de 11/50T y 10V. Estoy satisfecho con el resultado. Mi bicicleta es una RockRider 560S con tres platos y diez piñones. He montado un monoplato de 32T ovalado y este cassette en la parte posterior. No he cambiado ni el mando ni el desviador posterior. Simplemente se instala la patita de prolongación que viene con el kit, un pequeño ajuste del cambio posterior y listo. Eso sí plato nuevo, piñon nuevo y cadena nueva para 10 v. Lo recomiendo

Solid construction , shifts well came faster than advised

Premettiamo che ci ha messo un'eternità ad arrivare, ma purtoppo la prima volta il pacco si è perso. Il venditore gentilissimo lo ha rispedito ma nel mentre è esplosa l'emergenza per il coronavirus...quindi nulla da reclamare. È arrivato.Montato subito su Rockrider 520ST per poter affrontare salite più impegnative. La corona grossa si passa da 32 a 42, un bel salto. Grazie alla piccola flangia per il deragliatore (compresa) e a qualche piccola regolazione al cambio funziona bene. Provata solo in giardino perché #iorestoacasa.... quando sarà tutto finito e si potrà andare in giro farò un test.

11/46 cassette: I gave it a risky go to convert my old 3x9 to a 1x9 system with fairly good climbing gears (switched to a 30T narrow-wide chain ring in front) without replacing the shifter or the derailleur. While the mounting is as easy as for any cassette, it required quite some tweaking. The provided extension for the shifter eye is a MUST for my derailleur. The whole setup only just about worked after 1) replacing the original b-screw with a longer one to move it as low as it gets, 2) grinding down the derailleur cage not to get stuck at the 46T sprocket when shifting from the lowest (easiest) to the second to lowest gear, and 3) slightly correcting the chain line using a distance ring / washer between the inner part of the freehub and the new cassette (somehow left over of the old cassette..) -> this moved the cassette a bit outwards, so back paddling chain drops from the biggest sprocket are minimized (which seems to be a sign of proper adjustment). Still, there is slight resistance and a bit of clicking noise when climbing in the first gear, but as this was supposed to be a cheap hack I'm sill quite happy with the result.

Lo que me no haria es volverlo a comprar tuve que hacer 10 kilometros andando hasta llegar a la carretera y esperar a que me recogieran porque le saltó uno de los remaches del cassette y me lo dobló con lo que me lo inutilizó, por lo que tuve que venir a casa, os aporto las imágenes para que lo veais, no hace ni un año que lo compré.No lo aconsejo para nada,
