The STONE chainring, made in a CNC process with anodized surface and aluminum Aleris 7075-T651, is a wear-resistant and effective single-plate bicycle chainring in any terrain and time. Whatever the type of terrain, even the most bumpy, your chain will stay in place. Its optimized wide/narrow tooth system keeps the chain in place with the least friction and the greatest efficiency.
