Customer Reviews

Shimano Altus HG31 8 Speed MTB Cassette is rated 4.8 out of 5 by 5.
Rated 4 out of 5 by from Good like for like replacement Purchased as a like for like replacement for existing cassette. Great price, easy to fit (with correct tools). No problems so far. Fitted a couple of days after fitting a new chain, which was slipping using the old cassette. No chain slippage at all with the new cassette, nice & smooth.

Rated 5 out of 5 by from A rugged bargain. I recently converted an old road bike for use as CX / gravel / adventure bike and I wanted to go for more of a mountain bike type 3 x 8 gearing, I combined this cassette with an Atlus M310 rear mech., Altus M313-6 front mech. & M361 ( 42/32/22 ) Crankset. Everything fitted together perfectly and so far the set-up has coped with everything I've thrown it at.

Rated 5 out of 5 by from Direct replacement for my bike Had to replace cassette due to a worn chain (newbie me didnt realise). Direct replacement for my Carrera Subway One. Comes with 12-32 rivetted together and the 11 separate. If you have the tools, takes 5 mins to install. Really pleased with the price, i thought anything like this would be really expensive - if I'd noticed my worn chain the original one of these on my bike would still be pretty good after 2 1/2 yrs, approx 3000 miles

Q & A

Replacement for 7-Spd Hyperdrive-C?

Is this a good replacement for a Shimano Hyperdrive-C? If yes, is it easy? Are there any additional requirements/products need to accomplish this?
Asked by: BubbaMorse
Unfortunately not, we would recommend the HG50 7 speed cassette.

Screw-on?

This cassette appeared as a result of Googling "Shimano 8-speed screw-on cassette" Can you please confirm that it IS screw-on, because it doesn't look like it from the photograph. No mention in the product description, either./ With thanks
Asked by: DJBxxXXXXcxcxxxcxCcdxdDdc
This will not be a 'screw on' freewheel, and will be a cassette. From the sounds of what you are looking for it will be a freewheel (not cassette), if you could contact us we will be more then happy to assist and advise on what you will require. https://www.wiggle.co.uk/ContactUsForm

Which of the two options fits the Shimano Altus 8 speed rear mech

Asked by: cwaby
The Altus can handle both the 11-32 and the 11-34 cassettes.

Is this compatible with the Shimano Claris 2400 GS medium-cage rear derailleur?

Asked by: Tov1
The 11-32t option should be compatible with your derailleur.

Microshift Triple

Would this be compatible with a Microshift Triple (50/39/30) that currently has a 12-25 cassette? Thanks
Asked by: cyclec
Yes, would fit but you have to check your rear mech as well. You would need a medium or a long cage mech for the 11-32T cassette. If you require any further information, feel free to contact us: http://www.wiggle.co.uk/ContactUsForm
