Having been through a fair bit of gear failure on our road tandem, we eventually got it right, and dont have major dramas any more. (thanks to Chris king hubs, and a gates Belt). But the Fun is restarting again with our track bike. Im reaching out for help with Track Cogs, and anyones experiences so far.
We are generally using 100inch gear (48x13) but up to 112inch is common. The problem is keeping all 13 teeth on the rear!
The cogs that we have damaged so far are
Gebhardt 7075 Alu
Titanium CBC machined
Using both KMC Kool chain and Izumi SuperV chains.
Do I need to run much bigger chainrings and a 14 or 15 tooth cog?
At what point will the chainrings start to fail? (I am a big Gebhardt fan, and would be surprised if they failed)
Is there a better cog option that isnt likley to fail??
Thanks for sharing your experiences
