Rapunzel Posted April 2, 2017 Share I'm soon going to need to replace my worn cassette. What is the difference in durability between Shimano M7000 (482g) and Sunrace Rapide MX8 (404g)? Link to comment Share on other sites More sharing options...
gpcar Posted April 2, 2017 Share Not sure what other people's opinions are but I've come to realize the heaver the part the longer it lasts. This is not always the case but i see it as the general rule of thumb when it comes to groupset components. Link to comment Share on other sites More sharing options...
droo Posted April 3, 2017 Share Cassette wear is caused by a worn chain. If you change your chain before it wears out your cassette will last far longer - if you let your chain wear out you could make your cassette from diamond and it would still wear.

Wannabe Posted April 3, 2017 Share Rapunzel, I am using the Sunrace MX8 cassette for the last year or so. Been using it with two chains that I rotate, and to date, there is no wear on it that I can see.Done just on 2500km with it. Link to comment Share on other sites More sharing options...
whattingh Posted April 3, 2017 Share I agree with most comments above. invest in good chain and chain checker. Clean chain clean and lubed and cassette should last long Link to comment Share on other sites More sharing options...
Tatt Posted April 3, 2017 Share My 2 cents.... Had the new M8000 XT 42-11, that lasted around 3000 kms, replaced that with XT 40-11 and that lasted 900 kms. I get my bike serviced religiously, so chains replaced as required. The wear on the cassettes is purely on the alu rings, the rest are ok. Have switched to a an all steel Sunrace 42-11, unfortunately have only done around 150 kays on it, but so far it hasn't given any issues.

Kom Posted April 3, 2017 Share The OP seems to be more interested in Shimano related 11-Speed Cassettes, but as a side note SRAM XX1 11-Spd cassettes are bullet proof. Keep the chain and blade fresh and i reckon it will do 3000km, I wouldn't bother with 3rd party cassettes. On the blade front i might, but havent yet.

SCD Posted April 3, 2017 Share You cannot rely on service intervals for chain wear. Check it yourself once every 100km or so. Parktool has an updated chain-wear checking tool that is longer than the old models and offers a 0.5% measure. Or take it off and measure the length. As an example I was riding my last XX1 chain for over 1500km without reaching 0.5% measurable stretch. And then I reached 0.5% on a new XX1 chain just during 650km EPIC. River crossings and dusty/sandy trails thereafter are chainkillers, and during a race you don't stop to avoid this kind of stuff...And as Andrew said. Replace your chain in time and your cassette will last a very long time... Link to comment Share on other sites More sharing options...

Skylark Posted April 3, 2017 Share Considering how much you pay I bloody hope you get more than 3000km with an XX1 cassette!! Running cost on cassette alone over R1/km.. Link to comment Share on other sites More sharing options...
stefmeister Posted April 3, 2017 Share My XO1 cassette has 3200 km on now and still looks fine. Bought a replacement a while ago off ebay but it seems it's going to stay on the shelf for while still. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

BaGearA Posted April 4, 2017 Share So what cassettes are full steel ? I want to upgrade soon but I see the top cog on the slx cassette is Alu , being A lazy fart I will most likely use that a lot and wear it out quick while the rest of the cassette is fine. I'm A little weary of sunrace as i hear they Fuc# up chains Link to comment Share on other sites More sharing options...
Thermophage Posted April 4, 2017 Share I currently have the SunRace 11-42 cassette and have done 1455 km according to the Strava gods.So far all good. Have so far had 2 or 3 chains on it and it has been flawless.My XT M8000 cassette had about 2500km on it and the 11t and next up cog started slipping under power. That had 3 chains over the life with proper cleaning.So...will the SunRace last as long? I reckon so.Does it look cooler...? Yes...it's important Is it like 60% of the price...? YesShould I replace chains more frequently? Probably a Yes Droo I'd Get the SunRace 11-46 at present though and not the 11-42. You can play a little more with the front ring then too if you're feeling strong. Link to comment Share on other sites More sharing options...

At that rate you're are spending more on replacing chains than cassettes. Link to comment Share on other sites More sharing options...
