I've designed a spider to allow the use of off the shelf chainrings instead of being limited to the sickbikeparts 24T custom chainring.
It will likely require the use of custom chainring bolt spacers for each individual application, but these are readily available, as are various length chainring bolts.
104 BCD and 74 BCD and the sbp 2.63" BCD for the freewheel.
No modification to the freewheel required. Just find the spacers/chainring bolts that will work for you and that's it.
I'm going to machine one for myself and confirm that it works and fits. Then I will open it up to the public for order. I will not make any $ off these, it will be a break even project. I will only commission a single batch of these to be machined, after that I can make the CAD available to those who want it, or missed the group buy.
No firm dates yet but will keep posted on any progress.
Please leave a response below if you are interested so that I can reach out to you if and when this takes off.
