Without Hub damper
I purchased this product to install on my SEROW250.
The NORMAL Sprocket is Offset by Hub damper.
By using the SprocketAdapter, the Damper Offset is set and a wide range of Sprockets can be combined.
I have been wearing a XAM Sprocket carrier with an aluminum Sprocket on my SEROW for mountain activities, so I chose this one for my TwoSEROW for touring.
It's Steel's Sprocket for durability rather than weight savings.
I just installed it and it is the desired shape.
The shape of the Sprocket is more rugged than the Sample photo, so 4 stars.
It is lighter than the NORMAL, has a better Design, and is cheaper than the OEM.

Improved forward response when stirring Axel
Comparing this item with Normal sprocket, Hub damper is not present.
This allows power to be transmitted directly to the Chain. Therefore, the response delay of Axel is eliminated.

SEROW Rear SprocketAdapter
SEROW's Rear Sprocket has a hub function, so the Sprocket is rather expensive. This Adapter is designed to enable the use of DRC's Sprocket. View detail

428 to 520 Conversion
I bought this to convert the Chain size of my SEROW250 from OEM 428 to 520.
Because the circumference of the bolt hole is cut, it does not overlap with the Sprocket hole, so it looks refreshing and light.
The dark Silver or rather light Gun meta color has a high quality and the accuracy when installing was not a problem.
There may be an error because it is an actual measurement by Caliper that I have, but the color of OEMSprocket (Between Sprocket teeth and Wheel hub) was 9.6mm thick and the tooth was 7mm thick.
The thickness of the part corresponding to the collar of this product is 10.0mm, and it is the same as the thickness of the part for MC41 attached together. (Steel at 520Size) teeth is 6mm.
Made by ISA (Material with Size for 428):The thickness of the collar (Aluminum) was 10.5mm and the teeth were 7.3mm, so the thickness differs slightly depending on the product! (Internal LINK width of Chain is 7.94mm for 428 and 6.35mm for 520) 。
If you want to replace the Stud bolt by yourself, please note that the Stud bolt on the hub side is prone to trouble.
