TPN Posted March 24 Share Hi hubbers, I am looking for some advice. The GX cassette on my MTB needs to be replaced. Apart from fitting another GX cassette, I am considering two other options. 1. Using a SunRace CSMZ91X WT5 10-50T cassette. It uses XD hubs. It's almost half the cost of the GX. I am seeing mixed reviews on this cassette. 2. Replacing the XD hubs with Microspline and using an SLX or XT cassette. This works out simular in price to a GX cassette. In the long run it might be cheaper. What do you suggest?

BaGearA Posted March 24 Share I would not mix and match Although it might 'work' sram runs at its best with brand on brand. Get a 10-50 from bike addict for like 4k i think , if you look after the chain a gx cassette still gives lots of life. Shimano is a cheaper ecosystem and if changing the freehub i would change all together cause again , brand on brand works best. If you do go with the sunrace or shim cassette+ freehub option, either way it will probably work okay but will give less milage and worse quality shifting Link to comment Share on other sites More sharing options...

christovdw Posted March 24 Share Give keanbikes a go as well - got my GX cassette (10-50) for under 4k quite recently... DNC 1 Link to comment Share on other sites More sharing options...
Me rida my bicycle Posted March 24 Share I'm running Sram Lunar with Shimano XT cassette and chain. Has never missed a beat, shifts fast and quiet even shifting under load is smooth. My main reason was Shimano's ratios is just so much better than Sram and the overall smoother quiet ride is definitely a plus. That said I was building my bike from scratch with that in mind. Some freebodies are inexpensive and some are m#&r duur. So it might be cheaper just to go with the same cassette again.

TPN Posted March 24 Share Thanks guys. I see Keanbikes has a very good price for the GX cassette. I will go that route. Link to comment Share on other sites More sharing options...

Would suggest just bite the bullet, you won't be disappointed ! 071 491 4594 Pop me a whatsapp if you want we also have some cassets (new) chains and chainrings ! 10/52 T or 10/50T Kindest Edited March 24 by Bicycle Yard WESTERN CAPE Added info nonky 1 Link to comment Share on other sites More sharing options...

Currently running a gx cassette with 2 x01 chains and a xx1 chainring, switching chains every 500km, heard you can get some serious milage with that type of setup. guidodg and nonky 2 Link to comment Share on other sites More sharing options...

You throw them away ? My current GX cassette has 9500km and is as new, and I thought I was a bit extreme changing chains every 2000km or so, I'm running those KMC Gold Ti with hot wax melt setup and squirt top ups, and they hit the .25 wear mark at around that mileage, I'm sure with a XX1 chain I would do triple that distance. If I were to change chain every 500km I'd change them every week and half.. Edited March 25 by Jbr Link to comment Share on other sites More sharing options...

I get about 3500km out of them .... so not cheaper to run than other chains but they seem to run a lot cleaner which in turn saves the cassette. I did 13000km on the last X01 cassette which included some hectic mud crunching up in Africa Link to comment Share on other sites More sharing options...

I hope so although I don't really see the point of that, why not just clean the one chain and replace it once it's passed the .25 mark ? because once your two chains are passed that, you'll start chewing your cassette anyways Edited March 25 by Jbr Link to comment Share on other sites More sharing options...

PS: I do not rotate and just replace at 0.5 wear Link to comment Share on other sites More sharing options...

PS: I do not rotate and just replace at 0.5 wear yeah I've had a chain skip on a fresh chainring at just about .25 so I don't wait further to change chains those KMC's aren't that expensive and well rated in the friction tests so worth it imo Link to comment Share on other sites More sharing options...
