Very happy with a like for like swap. The same cassette lasted 2 years of constant use though because I tend to stick in 2 of the 7 gears for most of my riding that's where the wear was. The other 5 gears were unworn. Slick changing back
haven't fitted yet so.....

I replaced an old cassette with this one with no problems. It feels a lot better, together with a new chain.

Can I use this for my Dawes Galaxy Twin tandem?
03 Nov 2019
I need to replace the cassette (14-28t, around 38mm inside diameter) on my Galaxy Twin tandem. Would the Shimano Acera CS-HG41 7 Speed Cassette be suitable for it?
If not what is the product I need as well as the tool to take it off?
Yes this would work. We recommend -

Fitting on 11 Speed Hub
27 Jul 2018
I'm looking to experiment with fitting my old beater on my smart direct drive turbo as a permenant turbo bike. The turbo has an 11 speed hub, plus came with a spacer for "8-9-10" speed cassettes. Will that spacer be sufficient or will I need more (like the sproket washer mentioned in the other question)?
This should be okay without, but sometimes you do need that spacer depending on the particular hub shell / cassette.

Cassette loose on splines
10 Aug 2017
I have just replaced an old Shimano Exage 500X 7 speed cassette with a Shimano CS-HG41 7 Speed Cassette supplied by your good selves.
The old 6 sprocket stack appear to be thicker than the new ones. This means that when the lock ring is tightened, the 6 new sprockets are slightly loose on the splines.
It would appear that the gap between the 7th sprocket and the others is only about 1 mm.
Is there a thin spacer shim available for this setup?
Also, the old chain appears to ride up when used on the 11 tooth sprocket (it is fine on the other 6). Could a new chain prevent this?
Many thanks
You need to fit 2 (perhaps just 1) Shimano CS-HG50-7 Sprocket Washer - 1mm - Y11E03000 (our item # 6776) BEHIND the cassette as the Exage 500 hub was not designed for 11t top sprockets.
Is It A Design For Hybrid Also

As long as your bike is designed to take a 7spd cassette then this will be fine.
