Hello, Just wondering about using this system on a Fixed Gear bike. Does the rear COG just attach the same way that a fixed COG would attach?
Unfortunately we do not have a fixed gear cog available at the moment. This cog is compatible with 9-spline freehubs and we will be releasing a thread-on freewheel cog this summer!
where do you measure for the chain stay length? -mario
Here is a video on how to measure the minimum chainstay length!
Hello, I am excited of the possibility of switching to a belt drive. Will this work on both sides of a flip-flop hub, i.e., on the fixed gear side, or just the free hub side?
Unfortunately, this will not work on a flip-flop hub if it has the thread-on freewheel mounting and fixed gear mounting. This is compatible with standard 9-spline freehubs. However, we do have a freewheel cog in development and hope to have it available in the near future!
How large in diameter are the 64 & 72 BCD 130 chainrings? I have a 52 or 54 currently on my bike and it takes up most of the space for a chainring so I want to ensure these aren't too big.
Our 64T ring has an outer diameter of 170mm and the 72T ring is 190mm. Both rings are 18mm wide.
