Wolf Tooth single ring kit review£147.00

Superb one-by upgrade

BikeRadar score4.5/5

Wolf Tooth’s full set is the best performing single-ring upgrade we’ve used. The ‘Drop-Stop’ chainring is quiet and smooth under power, and the anodised teeth are holding up well. It comes in a vast range of options.

The expander cog is available in SRAM or Shimano synced designs, and if you’ve got a SRAM or Shimano XTR/XT cassette there’s a 16t sprocket that replaces the 15t and 17t sprockets for a smoother ratio range. Finally, if you’re running a Shimano rear mech, you can help it cope with the bigger cassette by fitting a longer ‘angle of dangle’ B-screw bolt or extended ‘Goat Link’ gear hanger.

The result is impressively smooth and consistent shifting right across the range, with no big gaps in revs and no need to carefully nurse the chain into the crawler cog, and we soon forgot we weren’t running a full-factory 1x transmission.
