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.*
