【Material】The Mountain bike chainring is made of high quality 7075 Aluminum Alloy, anodized surface,can prevent corrosion rust and color fading. CNC machining integrated, intensity is more secure, appply for long time cycling.
【Narrow Wide Tooth Design】 The positive tooth corresponding chian tooth width; tooth corresponding negative chain is narow. Teeth designed to prevent the chain from dropping. The narrow-wide chainring increases chain retention, wear life, reduces friction and noise.
【Teeth and Weight】32T(58g)/34T(54g)/36T(61g)/38T(71g)/±5g
