In aluminium 6061 T6 with black finish this chain tensioner system is designed to go only on our SCUD EVO3 frames.
It's made of:
2 external plates
2 internal plates which get thread to screw the bolt of the end of the dropout
4 small screws connecting these plates together to prevent them from falling during assembly or disassembly of the rear wheel ...
3 pairs of screws of different lengths to put at the end of the dropout of the frame following the position of the rear wheel.
2 x 10mm screws to use for your hub if your original screws have a thread area smaller than 35mm, but if your hub get a different thread than ours screws you can easily find on the market long screws with correct 35mm thread.
