This is hilarious. I bought the 8-40 on a lark to see if it would actually fit on my 97 bontrager privateer (a 3x8 drivetrain) and IT ACTUALLY DID.There is a cartoonishly tiny amount of space between the upper jockey wheel on the derailleur and the giant 40 tooth cog. But it isn't touching. IT WORKS.It even SHIFTS to the cog without complaint.I wanted something for that bike that would make it a real commuter beast, since I have a beast of a 25 degree slope hill on my ride home. Now I genuinely think this bike climbs it easier than my 750w ebike.We're talking 1.5 cranks to 1 wheel rotation. It pulls like a FREIGHT TRAIN.Great fun. Great upgrade. Can't speak to reliability yet but it feels just as good as brand new shimano set.

Works great on my commuter bike. Definitely heavier than the OEM Shimano/sram cassette but significantly cheaper. I've only put five or 600 miles on the cassette, but no complaints.

Used this cassette paired with a shimano deore clutched 11 spd derailleur and a sram 120 link chain to convert my 2018 Giant Talon 3 from a 3x8 to a 1x11. Fitting it to the bike was easy and the fitment was perfect. Shifts smooth and stays in gear no problem. All in all a great option for anyone looking to do a budget friendly conversion or even just as a replacement.

Got the wrong rim so had to order this for my bike, great product, way better than what I had, glad I broke the other one and replaced it with this, far more superior than the junk I had, shifts smooth and works great! Highly recommend! If needed would buy again! And the colors are great for my needs as well!

Needed a couple more lower range gears for climbs. Had the lowest at 32. Now I have 36 and 40. Seems exccesive at times but will adjust to at. Feels like cheating sometimes.

Like I said you, cant beat the price! Yes, its a bit heavier than the name brand but for what you get it is very a competitive cassette. I have used several of these "discount" cassettes and at times their shifts can be clunky. I believe the spacing is just a smidge different than "standard" however not a big deal as 99% of shifts are like butter. Installation is a breeze; all you need is a cassette removal tool, chain whip, and a bit of derailleur adjustment. Shipping was on time. I have found long-term durability comparable to known brands. Overall, it's a great budget cassette, I wouldn't put one on my S-Works however my Fat-tire needs a refresh and so I will surely be buying again!

Bien, solo falto la extensión (patita) que marca como un "plus"

one of my cogs just snapped and I wasn't even doing anything hard on it. i was street riding and 2 of my cogs were bent and had to throw it away. it is made from cheap aluminum. complete waste of money and is a safety issue.
