  • SRAM X5 crankset – can I replace inner chainring only?

    I have an SRAM 2×10 S1000 crankset (the OEM version of X5 I believe) with 38/24 chainrings. Is there any reason why I shouldn’t replace just the inner chainring with a 22T version, to give me a lower granny gear? I’m thinking about something like this:

    Many thanks for any advice on this one.

    That would work fine. Seems expensive though, I’m sure you could get something similar for less.

    There you go. 8 quid!

    Edit. Just noticed yours is sram, not sure if they are cross compatible with Shimano.

    any 64BCD 4 bolt chainring should fit, like the one davros linked. Unless there’s some kind of fiendish assymetrical bolt pattern…

    I feel like I’m getting a bit obsessive about this, but aren’t chainrings speed-specific? The SRAM spare parts catalogue lists six 22T 64mm rings. On some websites, the four ‘V3’ rings are listed as 9-speed.

    11.6215.089.000 CHAIN RING MTB 22T 64 V3 ALUMINUM HARD BLACK

    11.6215.064.000 CHAIN RING MTB 22T 64 V3 STEEL MATTE BLACK

    Also, I read somewhere that SRAM 2x chainrings are designed to be used in specific combinations, e.g. 36-22 or 38-24. So perhaps I should replace the big ring as well?

    Finally, is it better to go for steel for durability?

    If my bike wasn’t in another country (where the terrain is very steep!) I could just have a look at the crankset and that would help me a great deal…

    you;re definitely over thinking it 🙂

    you’ll have no problem with a 9 or 10 speed chainring and just get any brand in the material of your choice – steel lasts longer. It’s possible your front shift will not be quite a smooth with the bigger gap but try it and if its a disaster then replace the outer ring next.

    Thanks for the help Joemmo, will have a crack at it and hope it goes OK!
