TIAGRA/SORA Shimano Cassette Sprocket, CS-HG50-9 9-Speed

My old Specialized Allez with 3x9 running gear was quite worn.I used this cassette with the Shimano CN-HG93 Ultegra/XT 9-Speed Chain and now i have excellent, smooth shifting again.

Easy to install and worked right away.

This cassette works great. I replaced an old worn out Shimano Cassette with this one and a new chain. The bike has never ridden smoother. I have put close to 150 miles on this cassette and have had no issues at all. This is a great low cost cassette and I would buy one again.

I used this for my 8 to 9 speed conversion and it worked great. I don't know about durability and I don't care about weight so much but was nice to find this cassette in a variety of configurations--I chose 12/25T to keep the gearing changes small. I used the 9 speed HG53 chain and R440 flatbar shifters and the RD2300 (soon to be RD5701) rear derailleur.

I bought the 14-25 and actually disassembled the large cog carrier. This requires carefully punching out and filing the 3 pins that fix it as a unit. I then swapped the 25 for a 27, since I also switched to a single chainring. This left me the tight gaps I wanted, along with a lower first gear as my "bailout". Shifts great, I couldn't be happier with the results.

Glad I found this cassette, makes the hill climbs a little easier.

Did it get lost in the mail? once I got it, its a very nice piece; has nine sprockets versus the original 8 sprocket cassette; it gives me a larger sprocket , 30 versus 26, and one smaller sprocket, 11 versus 12. It should work with the original Shimano derailleur which is rated for 9 speeds and a max rear sprocket of 30 (or possibly 32 teeth); time will tell.

Hard to find 30 tooth 9 speed cassette. Quality made, it's a Shimano.

It's worked well on my two road bikes, I find the teeth wear out quickly though.
