29+ going forwards looks dubious, but not impossible to stock up and backfill with 2.8s.
The problem with going rowdy is the tires aren’t really built for it. Forks get interesting, either you have to find the Unicorn Fox 29+ or pick a fat fork.
I’ll put in a plug for 27.5 x 4 Van Helga 120 TPI, they roll really fast and feel more like a new experience than going from 29 x 2.4 to 3"
I want to keep to a rigid fork in this mental dither, but that’s always where I get confused geo-wise.
The Salsa Beargrease was another frame I always have an eye on. I know 29+ is a bit of a dead end, but that makes me consider it more as trying it before it might fully die. I have 1 Maxxis Chronicle 29x3 tucked safely away as a hope.
If Jeff Jones and unicyclists can keep the market for Duro Crux 3.25s going then at least you have a big aggressive option. Maybe Terrene keeps the Cake Eater 2.8 and then with the Teravail Oxbow 2.8 there’s a fast rolling option.
The 27.5 x 3 Oxbows on those Pub carbon plus rims were fun, light, chubby, fast rolling (perceptually, no idea about actual wattz).
Trek Stache might be worth keeping an eye out for too. This list is helpful, nice that they also list discontinued but worth looking for models at the bottom.
Look at the reach, the Beargrease has geo that’s almost as old as the Krampus. It might be pretty cramped compared to a modern bike like the Kona Unit.
I still have a large purple Jones LWB frameset with a unicrown fork if you’re Jones curious. At least height wise, you’re in the middle of their recommended range for the large size.
This makes sense if you have a use case for a fat bike. I have an Ice Cream Truck with this setup. Geometry is pretty modern. Top tube is long. There is a q-factor penalty with fat bb width.
After having a twisted DT Lynskey I’ve just realized I don’t want anything other than a regular straight tube frame. Just don’t like the ‘weird’ attention.
The seat tube on the Banshee Phantom is way too steep for 80% of my terrain which is flat with some technical undulating trails - no sustained climbs or descents.
I could go hard tail with my 140mm fork and gain maybe 2º, not sure if that’s enough. I don’t have as many choices as in the 'states.
I’m contemplating saying ‘screw this’ and going full rigid - the Nordest Sardinha 2 is pretty modern in reach and head angle, but has a seat tube around 74º which would work just fine. I could embrace ATB life for a while.
I probably need a ~22" top tube. My old track bike was a 56 mm ETT (effectively 22") and I would bang my knees on the stem bolts all the time. I’m leaning toward the older GT cos TAF.
