Hi Folks,
I've been immensely enjoying my 6kW tangent kit on my bike. It's seen about 500miles of use.
The inner chainring is now very worn and needs replacement. It's aluminum, I'd like to replace with a steel/hardened steel for greater durability.
It is mated to a freewheel crank mech, through a custom spider that also carries the final drive chainring. The final chainring has a BCD or 104 which is fine and standard sizing. But the inner chainring is the one that seems to have a custom/unorthodox BCD of about 66.5mm. This makes it impossible to source standard bicycle components for replacement.
Can anyone point me in the right direction?
