I was curious how the Wolftooth 42T GC cog would work – particularly with the shortcage Shimano Zee derailleur on my Santa Cruz Nomad.
I gave it a shot and it works just fine. I’ve got dozens of successfully rides in so far.
I removed the 15T cog as I use the bigger cogs much more than the smaller ones. I was going to ditch the 13T cog, but it mates with the 11T cog to generate the correct spacing so I left it.
What I used:
- 42T WT GC
- SRAM PG 1070 cassette
- SRAM chain PC 1031
- Shimano Zee derailleur and shifter
- Race Face 30T NW ring
- stock B tension screw [works fine]
- longer B tension screw that came with cog [works a bit better]
The shifting is not as good as either a stock 10 spd or stock 11 speed setup, but it’s just fine. If you are a really picky shifting snob you may find it too clunky for your tastes, but if you are just happy that it shifts up and down reliably you’ll enjoy it.
Since I installed my 42T WT cog a few months ago they have come out with a couple new options:
- 40T cog for those that want a smaller jump at the low end
- 16T cog to allow for better shifting down in the smaller cogs
I haven’t tried either of these.
