Review on Sturmey Archer 13 Tooth S3X Cog by Prince Castaneda

The Sturmey Archer 13 Tooth cog is a game-changer for serious cyclists .According to my experience, this cog MAKES for a smooth ride with minimal effort. The teeth are strong and sturdy holding up well under high speed and high torque. The only downside is that this cog may be too expensive for casual riders or those on a tight budget. Overall, I highly recommend this cog for anyone serious about their cycling game..
