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

I used this to replace the Sora cassette on my Specialized TriCross bike. I was initially going to give this 4 rather than 5 stars, because I am unsure whether this is a true Shimano product, (did not arrive in Shimano packagine, and the cover-nut is not laser-etched like the one it replaced - however the quality of this product has been fine, and even though it is not advertised as a replacement Sora part, it has worked very well replacing a skipping cassette cheaply and easily.Quite a nice touch, (and makes me think this is possibly not an OEM product), is that there are no spacers between the gears. All but the top 2 cogs are attached together in 1 piece, and the top 2 cogs have their own spacers attached to themselves, so you just stack them up - makes it a heck of a lot easier if you happen to drop the stack before fitting it !!!Time will tell whether this is as tough as a Shimano OEM would have been, (and apologies to the seller if this IS and OEM product, and I am simply mistaken), however first impressions are good although I've only done a few hundred miles.

working ok no problems with the unit

so above, renewed chain and cassette easier to order from amazon delivered to your door at no extra cost and cheaper then shops high street shops days are numbered.It will be a shame but money is the be all and end all.

Fit for purpose
