I'm content with this product, it's one of the best in its category. The chromium finish is good, it runs ok, let's see how much it will resist.
Excellent freewheel...world class customer service!

Excellent replacement freewheel for a 1x7 drivetrain (wanted to get rid of the 'mega range' Shimano freewheel, lower gear ratio makes for a much nicer ride!). Quality SunRace product, very happy with this purchase. This was my first order from BikeInn, and am very impressed with the prices, customer service, and the shipping time to Canada is pretty decent! Will definitely be a return customer! Thanks BikeInn...recommend you anyone looking for their cycling needs.

Thickness

Good morning, I would like to know the thickness of the package, how much space it takes up between the wheel and the frame. Thank you
Answer of Christian
Hello. Please be informed : although Bikeinn names this item "Cassette", this item is in reality what is named "Freewheel". This is a reminder of what A Freewheel or Screw-on cluster, is -on your rear wheel´s hub, on the drive-side, the hub has a threaded protrusion -this "Freewheel" has thread that will engage onto the thread of the rear-wheel´s hub : so you screw the Freewheel onto the hub You question specifies "thickness of the package". Hmm, I assume you meant "thickness of the cluster of cogs" I put the cluster on a flat surface and measured it twice with a measuring tape ( not as accurate as a calliper, but you don´t need 1/10mm accuracy ) : - thickness : 35,8mm, count it slightly less than 36mm - I have a 26-inch bicycle with 135mm distance from left side to right side (the technical name is "dropout distance") , at the rear, where you engage the axle of the wheel to fasten it to the bike´s rear - this Screw-on cluster (or "Freewheel" ) fits perfectly onto my hub - the resulting layout allows the chain to pass freely ; enough space for chain to pass between the smallest cog of the cluster, and the bike´s frame My answer refers to a bike with a dropout-distance of 135mm. If you bike has another value of dropout, you can do an educated guess, based on the value of 36mm thickness. I hope this helps you out. Happy year 2024, happy bike rides.
Answer of Guillem
It is compatible with steel frames from the 80s that have a distance between toenails of less than 130 mm. In my case I bought a Sunrace 7 crown freewheel sprocket to not have problems in my 80´s Orbea frame with 120mm dropout spacing and not have to force the chainstays and tie rods.
Answer of Trevor
Not sure the exact thickness of it but I can guarantee you that if you had another 6spd or 7spd freewheel it´ll fit straight on without a problem as I´ve done this many of times, no problems there. Sunrace are excellent quality.
Cassette 7v 16 - 25

Good morning, do you have a 7v cassette that starts with a 16 sprocket and ends in 25, thanks and regards
Answer of Christian
Hello. If I understood : you're looking for a cluster of cogs, which starts at 16 teeth and ends at 25 teeth. First : this article here is a cluster of cogs which attaches to the rear-wheel-hub, by screwing it on the hub. -therefore, this article is NOT what is called a Cassette ; the article is a Screw-on Freewheel -please do not be misled by the title "Cassette" of the article in Bikeinn webpage : the title unfortunately creates a confusion between Cassette and Screw-on -in other words, you need to know : does your wheel-hub take a Screw-on Freewheel, or a Cassette ? Those designs are completely different, NOT interchangeable ***please read this page for diagrams and details https://www.sheldonbrown.com/k7.html Second : this (Screw-on Freewheel) Sunrace MF-R30 has these steps of teeth : 13-15-17-19-21-23-25 -therefore, this article has a cog which has 17 teeth instead of the 16 teeth that you're looking for, very very close ! Third : in the day-to-day life of a cyclist, what a cyclist looks for is : { 1/ the Small cog should go as low as possible, in order to provide as high a Top speed (on horizontal or down-hill roads ) as possible -therefore 13 teeth is a very good small cog ! [ Because of engineering reasons, engineers cannot make cogs smaller than 13 teeh on Screw-on Freewheels ] -therefore I can't understand your specifying that you look for a 16 teeth : what is the reason to start with 16 teeth ? 2/ the Large cog should allow you to climb the steepest slope of your habitual bike-trips ; -manufacturers make Screw-on Freewheels and Cassettes with the Large cog at 28 teeth, or 30, or 32, 34, and even 40 teeth on Cassettes for the latest bikes which only have a Single chainring (versus the usual Triple chainring) -this article Sunrace MF-R30 has a Large cog at 25 teeth : this means it can NOT help you overcome very steep slopes, but the advantage is that it is slightly lighter than another Screw-on Freewheel which has a Large cog at 28 teeth, or bigger } Conclusion : -I had a quick look on the internet for cluster of cogs starting with 16 teeth and ending with 25 t : found nothing ! On the range 13-15-17-19-21-23-25, simply do not use the 13 and 15 if you think they are useless ; and you still have all the other cogs for use -please talk this over with your Local Bike Shop -please make sure whether your rear-wheel-hub takes a Screw-on Freewheel, or a Cassette ? Remember Those designs are completely different, NOT interchangeable Happy bike rides !
