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!)

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

Upgraded my son’s 2019 Cannondale Trail 24 with this cassette. Did have to use a longer chain for the bigger gear. Worked great.

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

Using this on my ebike , with a Shinano ACERA RD-M3020-SGS long cage . Perfect combo this cassette is 11,13,15,18,22,28,34,40 . which makes more scene for a e bike , wider mid range , good hill climbing and good top end . And You can't beat the price. These are steel , not light weigh , should take a pounding of the BBHSD. Top this off with a 46t ft chain ring and You have a beast !

Swapped out my 11-34t to this 11-40t on my road bike. Sunrace makes decent aftermarket components. Easily fit my shimano freehub. A spacer on the cog assembly may or may not be needed.You may need an extension hanger to attach to the rear dropout, and then re-attach your derailleur to that; otherwise your derailleur may not have enough clearance to put the chain on the largest cog.I was able to keep my rear derailleur -Shimano Deore M530- It has a long cage. A derailleur with a short cage may not work. Putting on a new chain will probably be needed

Got an old 99 GT Palomar for next to nothing to haul the kids in the trailer. Bottom of their line with twist shifters. Problem is while taking the boys on an adventure sometimes you need to hold a big old Chick-fil-A cup in one hand while you pedal and manage hills etc. So I got a 26” wheel with HG hub from the coop, put a Wolf Tooth road link on the rear derailleur, removed both old shifters, got a new 8 speed shifter and this cassette, and took off front derailleur. Using the middle ring (28/38/48) this thing has slightly better climbing gear than the old 28:28 ratio AND slightly better top gear with 38:11 than the former best 48:14. Great ratio and speed combination to make for a very economical 1x setup.

sunrace is good but the 40 tooth bent too easy
