SRAM drivetrain engineers optimized this ring to combat the high-torque, high-wear situations e-bike riders face. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel with a focus on long wear-life.104 BCD CompatibleSteel (34T,36T,38T)Backwards compatible with other Eagle TechnologySRAM Model ID: CR-TTYP-104-A1 table{border-collapse:collapse;width:100%;}td{text-align: left;padding: 8px;font-weight:350;}tr:nth-child(even){background-color:#f2f2f2}th{background-color:#eb212e;color:white;text-align:left;padding:8px;}.desc ul{font-size:24px;font-weight:600;margin-left:-25px;padding-top:35px;border-top:3px solid #f0f0f0;}.desc li{list-style:none;border-bottom:4px solid #eb212e;width:142px;} TECH SPECS BCD 104 Chainring Comp.
