Preparing a bike without maintenance for 12 years meant I had to replace the chain and then also the cassette. This one was great price, delivered fast and works well. I did have to buy a special key/tool to get the old one off and install this one as I didn’t have that.

Used this to replace a Sunrace set on an older Raleigh, and it fits and works fine. But don't try to cheap out like I did and try to re-use the chain. Even though the bike has fairly few miles on it and there was no visible wear on the old gears, there was very noticeable noise under load with the new sprockets until I did replace the chain. Works great now!

My old 1989 classic Schwinn Paramount build has nice Dura Ace 7401 7-speed shifting but you can’t get unused Dura Ace 7 speed obsolete cassette cogs and the 13-24 cassette was geared too high with my 52-42T Nuevo Record crank. A new 126mm rear wheel and this 14-28T freewheel shift perfectly with compatible 7 speed cog spacing and Uniglide shift ramps and lowered the gearing just as I wanted. I even exceeded the recommended 26T cog max and it still works great if the chain length is right. Nice smooth and fairly quiet pawl coasting noise. A Shimano-compatible Sunrace 7 speed 14-28T freewheel that I bought new at a bike shop for a quick fix shifted just as well but had a very slight wobble on coasting and had the small cog only a 1/4” from the dropout, so the genuine Shimano item seems a bit more precise. You’ll need a freewheel tool for removal. I also use the tool on installation because I make sure the freewheel turns on the hub threads smoothly clockwise and counterclockwise at the start to prevent cross-threading and trashing the hub threads (a big pitfall for home mechanics not familiar with old style freewheels).

Remember to buy the removal tool before buying the cassette or you going to have to buy and wait. I found the cassette removal tool that is highly purchased with this cassette. Once you have that you can use a 20+ adjustable wrench to do the job. Did this on a chinese electric mountain bike that came with this same cassette. Very easy to do and everything wemt smoothly and works.

I had to replace my freewheel after the original fell apart. I found it was cheaper to replace it than try to repair the old one. I'd never replaced one before, but with the help of YouTube and a freewheel lock ring removal tool (NOT the cassette tool; mandatory but inexpensive) I was able to get the old freewheel off the hub and install this new one without too much trouble (and all for less than $30). Clicks in reverse and operates exactly as it should. Very pleased for now, time will tell if it holds up.

14-16-18-20-22-24-28T22Tか24Tでスタートし、カチャカチャと小気味よくシフトアップする。ペダルが軽い。13年買い物で乗り続け、古ぼけてしまった鉄フレームのママチャリをレストア。我が家の生活を支えてくれた感謝を込めピカピカに。そのついでに内装3段をフロント3枚/リア7段の多段化(21段)に改造。ディレイラーやクランクなどの部品が余っていたから。家の周辺は坂が多く内装3段では行けなかった所も難なく行ける。かねてから構想していた買い物スペシャル。前カゴ後ろカゴにお米や野菜、ジュースやビールで時には積載量20キロを超えることも。34Tのマルチプルフリーホイールを入れ激坂対応も考えましたが、フロントは42T/32T/22Tと三枚あるのでシフトチェンジの繋がりを優先し28Tを選択。結果、登板能力も十分で急に重くなったり軽くなったりせず調子よく漕げてます。
