Product details
Made in the USA from a machined 7075 aluminum alloy, the RENNEN chainring is unique due to its decimal tooth arrangement, which results from a slight modification of the ring's circumference. This allows you to adjust your gear ratio in fractions of teeth depending on the requirements of the BMX track you will be riding on. It is designed for mounting on a 4-bolt pedal crankset.
Features:
• CNC-machined 7075-T6 aluminum
• 4-bolt mounting, BCD diameter 104 mm
• Decimal teeth
• Thickness: NC
• Chain pitch: 3/32"
• Weight: 102 g (44.2 teeth).
