Sun Race CSM680 Cassette 8-Speed 11-40T Black

Fits right up to a Shimano freehub. Comes with the locking ring, no derailleur adapter. Similar to what another individual wrote, this is almost a must have for anyone building the “Family Beater/Bike Path” bike. This was installed on free to me GT Timberline 1.0 size large that’s being converted to 1x drivetrain. It’ll be used to pull a kids trailer while I sip on a big ol’ Chic Filet soda riding down bike paths. I have what looks to be a Shimano Altus long cage on the bike and was able to get it to work by replacing the b-screw with a longer one. You will require a chain whip and cassette tool to perform the install. All in all, a good budget friendly option for converting your drivetrain.

Used this cassette with a 1x conversion and have great gear ratios for the hilly riding I do. Easy install and dialed in with an equally affordable shimano acera derailleur, chain shifts through the gears perfectly. Have put a couple hundred miles on it and hasnt skipped a beat, though I do clean & lube the drivetrain often

A great upgrade for an Aventon LEVEL II, along with a Shimano Acera derailleur! 5 stars for quick shipping, price and ease of setup! (Recommended!)

I had an 8 speed 11-34t cassette and I wanted a little more easier gear all of the cassettes that have 36 tooth you had to go to 9 speed and I did not want to get a new derailleur and shifter. I was a little bit hesitant about getting this because it is in 11-40t cassette with my front chainring is 34 22 I thought it would might popping snapping not work properly when in 22 tooth chainring but it works perfectly there is no snapping popping skipping gears none of that. The installation was a breeze no problems everything lined up just had to adjust the B screw so the derailleur could go onto the 40t sprocket. My rear derailleur is a Sram X5 8 / 9 speed derailleur seems fine with going onto the 40t sprocket the price was good to everywhere else I look they wanted $40-50 for this same cassette

I've been abusing this thing for about 1.5 yrs now and it is still going strong. My only complaint is that backpedaling in 1st gear will cause the chain to jump down to 2nd. I have another cassette with a larger 1st gear and the same alignment (same bike actually) that does not do this, but honestly that isn't that big a deal. This is a good quality cassette for the money.

Very nice looking durable Was fairly simple to put on you must have the right tools. I Will update after 100 miles or so and some hill climbing... Update I road 200 plus Miles and some 10 % inclines , this thing is solid. Must buy we'll buy again and recommend.

Used on Schwinn axum to replace broken original. It shifts better now than it did new. Happy for the price

sunrace is good but the 40 tooth bent too easy
