Using your Promax CK - 1 Carbon Crankset is easy. First, make sure you have the right bottom bracket as it's sold separately. Install it according to the standard procedure for your bike. Attach the pedal washers that come with the crankset to the pedals before mounting them on the crank arms. If you're using a SRAM 3 - bolt chainring, ensure you have the appropriate bolts (SKU CK2203 is recommended). For those who want to use the 4 - bolt 104 BCD chainring adapter, you'll need to buy it separately and install it correctly. When riding, you'll notice the smooth power transfer and the lightweight feel. To maintain your crankset, clean it regularly with a mild soap and water solution. After cleaning, dry it thoroughly to prevent rust. Check the bolts periodically to make sure they're tightened properly. Avoid using harsh chemicals or abrasive materials on the carbon crank arms as they can damage the surface.
