The Promax Direct Mount Crank Spider in black is a high - quality aluminum adapter. It's specially crafted for the Promax CK - 1 carbon cranks. With this adapter, you can easily use a 104 BCD chainring with your CK - 1 cranks. The high - quality aluminum offers great strength while being lightweight. It uses SRAM's 3 - bolt mount style to attach to the crankarm (bolts sold separately, SKU number CK2203 recommended). Note that it's not compatible with Promax HF - 3 cranks. Ideal for 4 - bolt 104 BCD chainrings.
Using this Promax Direct Mount Crank Spider is easy. First, make sure you have the Promax CK - 1 carbon cranks. You'll need to buy the bolts separately (SKU number CK2203 is recommended). Then, use the SRAM 3 - bolt mount style to attach the spider to the crankarm. Install your 4 - bolt 104 BCD chainring on it. Remember, this spider is not for Promax HF - 3 cranks. For maintenance, keep it clean and dry. If you notice any signs of wear, check the bolts and the spider itself. Replace parts if necessary to ensure smooth operation.
