I can speak for my direct experience. I have a 2019 29" Lyrik with a 29x3.0 Maxxis Minion DHRII installed. Plenty of mud clearance.

Do most boost forks fit 29+?
I'm looking at building up a hardtail as secondary bike to ride on trails where my full suspension would be overkill, tow the chariot, and possibly do some winter riding. I have a 35mm 29er wheelset so I figured I could build up a bike and run 29 x 2.6 XC tires in the spring/summer/fall and then toss some studded 29 x 2.8 tires on there for winter riding if I ever wanted to get into that.
I have my eye on the Esker Japhy as the frame seems to have good clearance for 29+ and by all accounts rides very nicely. However, I was wondering if I'll need to buy a specific 29+ fork or if most boost forks will accommodate a 29 x 2.8 on a 35mm rim. If not all boost forks will work can anyone share which ones they know will work?
Thanks

Not all boost forks will work. The Sid SL for example i think has a 2.4” tire max.
These are the boost forks I’ve used (and can remember) that fit a 29x3.0 tire.

I'm told the Rockshox Pike can fit 29+ also.
Fox says their awl 29er version can do 2.8 or 2.6 with fenders. https://www.ridefox.com/family.php?m=bike&family=awl

Just because it clears the brace doesn't mean it's safe to ride.
Measure clearance to the crown and allow extra for wheel flex.

Fox says 2.5" for the 34 performance elite 130mm fork that came stock on my 2022 Spark.
FYI Unfortunately the Japhy does NOT have good 29+ tire clearance. They tried to say it did initially but many users have to run the dropouts middle - toward the back to not have frame rub with 2.6 on i35 rims. I had my name on one of the second batch frames, until I discovered this info. Turns out they just tested their McFly 2.8 on i30 rims, which is realistically a 2.6 tire not a true 2.8I have my eye on the Esker Japhy as the frame seems to have good clearance for 29+
Marzocchi Z1 & Z2 clear 29+ easily and also all 2018 (and newer) RockShox 35mm forks clear 29+ (SID 35 being the exception).
I was looking at running the 29 x 2.8 Cake Eater for winter riding but doing a little more reading it sounds like that tire is undersized. I'm wondering if it'll fit frames with 2.6 clearance as that will open me up to significantly more options.
Is there like a guide that shows what the max clearance on each RS model is & general differences between them? Do you know the max on the SID 35?Marzocchi Z1 & Z2 clear 29+ easily and also all 2018 (and newer) RockShox 35mm forks clear 29+ (SID 35 being the exception).
I know the Z2 shares some bits with the Fox34 if I remember correctly. Would the Fox34 AWL an e-bike version of Z2 with rack mounts since clearance seems to be the same as the Z2 & not other 34 models?
Not sure on the Fox 34 AWL, they do share some internals but the lowers/arch area is different (best I remember). Here's a pic another user took of a Rekon 2.8 on i45 in SID-Is there like a guide that shows what the max clearance on each RS model is & general differences between them? Do you know the max on the SID 35?

I live SoCal so mud not an issue here. Has me thinking maybe Sid 35 now.
