8 Speed Cassette 11-42T 11-40T MTB Cassette 8 Speed Fit for Mountain Bike, Road Bicycle, MTB, BMX, SRAM, Shimano, Gears for Bicycles

Due to my usual supplier having inventory issues I decided to take the amazon route for this cassette instead of a Microshift I was looking at. This cassette was installed on a 2008 Kona Dew Plus that I had turned into a gravel bike. So far I only have almost 200 miles on it but it's been through rain, mud and a ton of dust and shifts great. I will update if I have any catastrophic failures :P On a side note I have taken it on some technical singletrack and this hub has crap engagement and being a cross country mtb racer I torqued really hard on this thing and it handled it fine. Definitely durable. Legit value for money.

Best upgrade I ever did to my cheap Walmart bike.

Really nice quality. Great upgrade.

I have this on a bike that gets plenty of use, commuting and crap weather riding. I have been through one chain on it and it's still going. The shifting isn't Ultegra by any means and the gaps between gears are quite noticeable in places but it's perfect for me. It's been quite solid and reliable and has the range for my ghetto 1x setup to work really well. I just got another one so I have a spare on hand when I kill it. I'm hoping to get two more chains out of my first one. Good value cassette.

1. **Gears and Shifters**: Use the shifters to change gears.2. **High Gear**: Harder to pedal, good for speed/downhill.3. **Low Gear**: Easier to pedal, good for uphill.Shift low for hills, high for speed. Practice helps!

Bought it less than a Month. 3rd time out riding and one of the gears broke off... hoping this was just a defective piece and waiting for seller’s reply.Update 11/03: seller sent the replacement. Received today the complete COG and I only expected them to send that one broken gear. Excellent communication/service and kudos to them for standing behind their product.

Price is great, product not great 😕

In all fairness I am using this on a 2kW emtb ebike which is probably not what it is designed for. This is my second one, the first one wore out on most of the gears in about a month's worth of rough riding. The second one folded like taco after about 5min of testing its ability to hill climb on the lowest gear. Chain alignment was pretty good, so I think I just need a more robust design with something less than 42 teeth.
