Shimano HG51 8 Speed Cassette

Great cassette , reasonable price and it will do it's turn im sure.

Good quality Shimano cassette for your HG hub. I bought this to replace the factory fitted Sunrace cassette that came on my Merida hybrid bike. The hardest part of any cassette installation is getting the old one off. The Shimano nickel finish looks amazing and the black decals go with my black bike. Paired with a new chain I hope to get well over 2000 miles out of this before I consider changing it. Disappointingly the Amazon service on this order was poor - it stated delivery within a few days but it took nearly a month and arrived from Europe. Seeing as I could have gotten it cheaper elsewhere with a quicker lead time i nearly cancelled the order. Luckily I wasn’t in a rush for it.

This makes a good upgrade for most 8-speed budget hybrids and mountainbikes. I fitted one of these to a Ridgeback Velocity and a Scott Aspect 50 and in both cases the bikes now run a lot smoother. In both cases I also changed the chains to a KMC Z8S and also added a new Alivio crankset to the Ridgeback. You'll need the right tools to do the job, a chainwhip and shimano compatible cassette removal tool (and maybe a chainbreaker depending on your old chain). You'll also need a crankset tool to remove a crankset (if you change it which is recommended if it's worn badly, otherwise the chain will wear out faster). All very easy if you've got moderate mechanical skills and lot cheaper than getting a bike shop to do it.

Very good value. Good quality.

Very good. Quite easy to put on.

I find in the middle between fourth and fifth gear, the four is easy and the five is hard, almost like there should be another gear between them, so not perfect for me but runs smoothly on my ride

Easy to fit and sorted my gears jumping. Now I have smooth gear changes again.

I usually use Shimano. This model, I will use soon to prepare new wheel, for my bike. It is good quality and price product. Of course, you should be perfectly sure what you are buying. The product fits for specific hub, derailleur and other bike elements. If you are not a bike expert, read manual and technical documents first. This is Alivio class according to Shimano, so it should be good for all user and has high/medium quality. I can recommend this class of Shimano product, specially for normal users. Higher class sprockets are recommended if you are high quality focused or you are a professional, racing biker (but they usually know what they want without reading any comments). Higher class elements, usually are slightly lighter and made of harder materials.

very good service and product

Quick Notes: - Great quality cassette that’s light in weight.(I didn’t put it on a scale but just holding it I could tell it weighs less than 1lb.) - Easy to install you just need a chain whip or an old chain and some gloves (is what I use) and a Shimano freewheel remover to take off your old cassette and just the freewheel tool to install the new cassette. - Can take a lot of force being applied to it without any chain slippage. - Up shifting (high toothed gears) is as smooth as butter and has the smoothest down shifting (lower toothed gears) that I’ve experienced out of any cassette I’ve used. - Becomes super shinny again when cleaned with simple degreaser. - I would recommend this cassette to anyone looking to replace or just upgrade their current cassette. Full Review: I’ve used this cassette every day for 3 weeks now and have put a few hundred miles on if so far and I’m very pleased with its performance. I installed this cassette in less than ten minutes including setup. To replace a cassette you will need a chain whip and a Shimano Freewheel remover. It’s worth noting that if your cheap like I am you can just use an old chain and hold it with some gloves to prevent the old cassette from moving when removing it. The chain isn’t needed when installing the new cassette just the freewheel tool. If you are unsure of how to change a cassette look it up on YouTube or take it to your local bike shop or if I get 5+ comments asking about installation I’ll make a video of how to replace a cassette but there already tones on YouTube if you are unsure of what you are doing. Now about the performance of the cassette up shifting on this cassette is like most others its butter smooth but much to my surprise this cassette dramatically improved the ease of my down shifts it almost never slams into any gear the only gear slam I notice is going from 28T down to 24T and I assume the 32T to 28T is probably the same but I’ve haven’t had to go into 32T yet in a real world ride. Every other down shift though is very smooth it is important to note that in order to get smooth shifts it’s not just the cassette that matters but your derailleur and shifters as well. My personal set up is a Shimano Acera M360 derailleur and Shimano Acera SL-M310 Shifters. The next cassette I order though will probably be a 11-30T simply because I’ve climbed some pretty steep hills any only ever felt the need to go to 28T but if you are new to mountain biking you will probably want to get a 11-32 just to make sure you can climb any hill. You can also really crank out the power on this cassette and not have to worry about chain slippage, which is great if you like doing burst power workout rides like me or if you are on the heavier side and looking for a quality cassette to go with a bike that you can use for some basic exercise. But the best part of this Cassette is by far its durability with scratch resistance. When you clean your bike after a long off road venture that gets everything covered in mud just spray some degreaser on your cassette and spray it off with a hose and it will look brand new again. I have no problem recommending this cassette so anyone its fairly inexpensive and the performance is miles ahead of any of the cheaper cassettes that really makes this cassette worth spending the extra 10 bucks on. --*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.*
