Noob here. Looking for some advice to replace the chainrings on my 2011 29er Stumpjumper FSR Comp. I currently have for the stock crankset: Crankset Custom SRAM S-1250, 10 speed XC Trail double, GXP spindle, XC guard, 175 mm. Chainrings are 22A/33A XC shift guard, 4 bolt, 104/64mm. Looking not to upgrade but stay the same. My chain wear is about 1 so I was thinking about changing my chainrings and cassette. Any advice appreciated. Remember,,,,,Noob here.
