CYBREI Standard Spider
What is
The CYBREI Standard Spider is the "spider" that connects the crank arms to the chainring on a bicycle. It's the intermediate component between the crank arm and the chainring, to which the bolts that secure the chainring are screwed. In many drivetrains, this part is essential for properly mounting the chainring and ensuring efficient power transfer.
Technical specifications

Main advantages
-
Lightweight and strong : At only 40g made of AL7075 aluminum, it maintains the necessary rigidity without adding unnecessary weight to the drivetrain.
-
Versatility : Compatible with CYBREI cranks, allowing you to mount different chainrings depending on the use (road, gravel, fixed-gear, etc.).
-
Ease of assembly : Being a standard spider, it simplifies the installation or replacement of the crankset — useful if you are building the bike from scratch or upgrading components.
-
Transmission efficiency : By correctly connecting the crank to the chainring, it ensures good power transfer when pedaling.
🔧 What is it for?
The spider is an essential component if your bike uses removable cranks with bolt-on chainrings (instead of a single-sided crankset):
-
It allows the chainring to be fixed to the crank arm using screws;
-
Facilitates the assembly of different sizes or configurations of chainrings (according to your needs: road, gravel, fixed, etc.);
-
It's useful as a spare if the original spider is damaged, or if you want to reduce weight by optimizing components.
