• Material: the bike chainring is made of high quality anodic oxidation 7075 T6 aluminium alloy, aerospace grade strength.
• Very Durable and Stiff: FIFTY-FIFTY 104 chainring is 4.5mm thickness plant to ensure the 104mm BCD MTB chainring no flexing.
• Narrow Wide Tooth Design: The narrow-wide chainring increases chain retention and wear life, no chain drop, reduces friction and noise.
• Compatible with 9/10/11 speeds, ideal for replacing old chainrings or converting 2 or 3 speed chainrings to single speed. Comes with 4 aluminum alloy chainring bolts. (Tighten to recommended torque, do not over tighten.)
• Light Weight: 30T (36g/1.27oz) / 32T (36g/1.27oz) / 34T (48g/1.69oz) / 36T (60g/2.12oz)
