Replacing chain rings

hi all.

Newbie here. I have a GT Zaskar and finally got round to replacing the chain to realise I need a new cassette. This done I had slipping which I have narrowed down to worn chain rings, unsurprisingly, im a weighty guy and its had a lot of use. However, I can find a replacement outer ring but have been searching for 2 days for the inner ring. Am I missing something? I can only find the pair with a whole new crank set for a fair bit of cash. Is this only how they come? I'm surprised that I cant just buy them as a pair.

I'm after Shimano SLX FCM675 10 Speed Double Chainrings but can only find the outer ring.

Its all a learning curve for me but enjoying learning to do my own maintenance, but I'm stumped.

    You should be able to pick up the individual chainrings new from ebay easily enough. Just make sure that bcd and tooth count match your old ones.

    I had similar issue searching by OEM crank set part number, if you know the individual chainring part number it's a lot easier to find.

    You just need a chainring with a 64mm BCD.
    CRC have the 24T ring for £21 if you want to stick with Shimano.
    SJS Cycles have a 26T ring or a 28T ring for £15.
