Ratio Tech brings 34T and 36T chainrings to GRX cranks

Best known for its SRAM shifter upgrade kits, and recently, its own modular rear derailleur, Ratio Tech is back with another new product to fill a market gap. The UK-based manufacturer is now offering chainrings to suit Shimano GRX asymmetrical 4-bolt cranks. While Shimano itself offers 1x rings down to 38T, Ratio is offering sizes of 38T, 36T, and a truly unique 34T. The rings are 1x-specific, with a tooth profile claimed to be compatible with 11, 12, and 13-speed chains. The rings are machined in the UK from 7075 aluminium and priced from £60 / US$67 / €58 / AU$95.
