Thanks for comments – I’ll check out the Rohloff tensioner.
@MrPottatoHead – good point, you would think I would be able to, but currently the Anthem is in bits as I took the drivetrain off it for my On One C29er Race. So hope was I could save some cash and build up single-speed for awhile – but wanted to get the STW wisdom on it before I fork out for cog/spacers (instead of cassette) and tensioner (instead of derailleur).
I do already have a 32 tooth Widgit, as I previously ran the Anthem as 1×10, but still need to get some cheap cranks to fit as well…
