I'd like to resurrect this thread since I have the exact same question in late 2024:
I'm looking for something that rolls fast on frozen dirt and well packed snow. Mostly will be riding them on those freeze-thaw days, might be calling them into action for a race or event when conditions seem pretty firm. It seems like the options are:
- Terrene Cake Eater Light, unstudded, 27.5 x 4.0, Bead to bead: 217mm, claimed weight: 1325g
- 45Nrth Dillinger 4, unstudded, 27.5 x 4.0, B2B: 230mm, claimed weight 1400g
- 45Nrth Vanhelga 27.5 x 4.0, B2B: 238mm, actual weight: 1423g
- Bontrager Barbegazi 27.5 x 4.5, B2B: 255mm, actual weight: 1310g
Barbegazi is the lightest and the highest volume. I was leaning towards a smaller diameter tire because I thought it would be more nimble and have less self steer, but maybe that's not really a factor. Cake Eater is the smallest and also pretty light. The current D4's look more aggressive than the old ones I used, which seems a good thing in most cases but not for my purposes. And then there's the VanHelga, which I found to roll surprisingly fast in the old 26" version. It may have been in my head but I liked them better in the dirt than D5s.
Does anyone have any real experience that could help me out here?
