New chainrings for SRAM 2x10 chainset

stubs

My new 29er bike has a SRAM 2x10 chainset with 39/26 tooth rings. Finding the gearing is a bit high for grinding uphill. Planning to do Snowdon in a couple of weeks and would like to drop to a 24T granny and 36 or 38T big ring. Having trouble tracking down anywhere that sells rings in the SRAM BCD sizes of 120mm and 86mm (I think its 86mm googled size but havent taken crank apart to measure accurately). Googling is not bringing much up apart from a couple of places selling just the original 39/26 sizes.

Anyone point me in the right direction.

edit:think the granny ring BCD is actually 80mm not 86mm

They obviously do make what you are after and recommend the range for 29 ers

I have ended up buying a 2nd hand 36/24 crankset off ebay. Just couldnt find anywhere selling them new must be a manufacturers option only, or not imported into EU.
