Praxis Works Single Speed 104 chainring£39.99

Single ring with standard depth teeth

BikeRadar score3/5

Praxis Works chainrings have earned a cult following for their strength and durability in the US, but their single ring isn’t exactly remarkable. 

The main difference is that, while the twin and triple rings are cold-forged for grain-realigning strength and then machined, the single ring is stamped and then machined. We haven’t folded it or crushed teeth on it, though, despite a few boulder bangs, and it’s wearing well so far. 

The teeth are standard depth rather than extended and fattened like SRAM’s XX1 or some other single-ring specific designs out there, which help improve chain security. The shoulders are also sloped and narrow rather than squared, and there’s no built-in bashring like on the new Hope ring. 

It runs very smoothly with no suck even on dirty chains. The 32-38T sizes include odd numbers if you’re really fussy about your gearing too.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
