Interbike 2015: Praxis Works’ forged steel n/w chainring

In addition to a new creak-free Cinch-compatible expanding bottom bracket and some new OEM-level cranks, Praxis Works was on hand at Interbike showing what is likely to be one of the hardest-wearing chainrings going. Forged from 4130 cromoly steel, the prototype chainring should be the “mothership of reliability,” with three times the wear of alloy.  Tooling for this sort of thing, of course, isn’t cheap- which means that the chainring will be limited to a single size (32t) and bolt pattern (104mm) to start.  One for the singlespeeders and one-by tourers, perhaps?

Praxis Works will also be offering this handsome replacement chainring for Shimano M8000 XT and M9000 XTR cranksets and their funky irregular bolt pattern.  At $50ish, it should run about half what Shimano’s replacements do- and with a narrow/wide profile, it was implied that chain retention would also improve.

    Why would a single speeder need a N/W chainring then? 😉 purty though it is.

    Stoner,
    I use one on the singlespeed- it allows a little more confidence when the chain stretches and should wear better than a straight chainring (thanks to a shade more bearing surface).

    I use an elliptical ring on my s/s. i.e. the chain goes from slack to less slack on every revolution and never had a chain drop in all my years. And as for wear, it’s pretty much the least important thing on a single speed drivetrain.

    As great at what they do N/W chains are, they’re really an irrelevance to SS.
