[#11054852]

Just ordering some parts for a mate and he's also looking at a new cahin ring. Does anyone know if the SRAM X-Sync 2 Steel Direct Mount Chain Ring fitted is Boost or not??

Linky to bike - https://www.specializedconceptstore.co.uk/product/13952/2019-men-s-stumpjumper-comp-carbon-27-5-12-speed/

I can see its DM and assume its Boost but does anyone know for sure

Cheers
Carlos

It should be boost and have the offset stamped on it if you have access to it. Both ours are 3mm

Thanks Tracey.

I don't have access to his bike atm and thought I'd ask on here so I can add it to the basket of other bits.

Yeah pricey indeed, but he's running NX and they are about £15
