SHIMANOAcera Cassette Sprocket CS-HG41

A quality Shimano part that installs cleanly and works well. One issue with the 11 speed is that teeth seem to wear out faster than on smaller cassettes such as my 7 and 8 speed bikes.

I've used these Shimano cassettes for years. The HG-41 is the top model 7 speed. They last thousands of miles as long as you replace your chain regularly. I also use an HG-51 8 speed on my 1997 Trek 830 with aftermarket rims. Why is the 11 tooth sprocket, and retaining ring black? Not a big deal, just odd. I purchased mine as a return for half the price of new. Great product for older bikes, and they always shift smooth!

I bought this to replaced a worn out cassette on my Trek Marlin 6. 100+ miles in and it's still working great! I went to the 11-34 for a better uphill gear and am very pleased with the setup.

It seems excellent! I replaced the original Shimano cassette with this new one and have ridden twice so far and the cassette works really well. I'd definitely recommend this cassette. The only thing I didn't like was that the cardboard box has a open window cutout without any plastic over the window, and the cassette itself isn't wrapped or protected in any way from sticking out through the window opening. This is no problem in a retail store but doesn't seem the best when it's being shipped. It did arrive in perfect shape but I would still have preferred it be wrapped inside the box to make sure no sprockets got damaged in transit while sticking out of the box window cutout. Other than that I'm very happy with it and would buy from this seller again.

The cassette and other parts were packed loosely in the box and the second smallest sprocket is missing. The teeth on each sprocket look poorly machined and, as another reviewer pointed out, don't have the number of teeth embossed on the face of the sprockets, making it unlikely that these were actually manufactured by Shimano. I wouldn't recommend gambling with purchasing one of these.

Purchased to replace an old/worn like-geared (7-speed 11-28T) IG31 Hyperglide-C cassette on a mid-90's Trek MTB. This unit is a simple, drop-in, 5-minute replacement that requires no other modifications (aside from a little post-install shifter adjustment of course). Paired it with an HG70 chain to replace the also-worn original IG30.The new cassette works perfectly. Pedaling is now a bit smoother. Shifting is now much smoother, quicker, and more accurate. Also, there's no longer a tendency for the chain to want to hop sprockets under load (never could get that adjusted out with the old cassette/chain after a while).About the only negative is that Shimano doesn't make it very easy to determine the proper replacements for discontinued parts.

Great product. Beautiful. Smooth

Perfect fit for my 90s mb. Great price and solid construction
