    Not many Jumbo Jims O.E. Equipped for 2020

    Just happened to notice very few bikes this year come with JJs,supply? Price? Other reasons?

    While I like the speed of my JJs they do seem to side slip a lot on off cambers and anything that is not hit dead center.

    Looks like Schwalbe had their day in the sun. Some companies are likely using less expensive choices.

    On the washouts, air pressure is a leading cause. There are better choices of tread pattern for the rowdy times in loose and off camber. The cost, severely reduced fuel economy.

    Looking at Trek, their fat line had the Gnarwal or Barb's while the + line had Nobby Nic 3.0's until this season when they offered their tires. That had to have been a good contract for Schwalbe at the time.

    My main issue with JJ is when riding a bench cut that traverses a ravine and you have to ride up onto the berm of the cut at the exit of the ravine and bike is back to vertical the front tire slips back down and the back tire arcs off of the inside of the trail,sometimes itís a big drop off. (Think rock stacked shelf to get you across the ravine) Easiest solution would be to just hop the back wheel over but I ainít too good at that. Hard to give up the easy rolling tires, maybe a minion on front? I donít think any rideable air pressure adjustment will help the JJs


    However,I donít think the lack of OE spec is due to performance characteristics,the price must be outweighing the rolling resistance benefits and the what,maybe Pound and a half weight advantage?

    As mentioned, rowdy times require a proper selection and is precisely why I have a few pair of tires to choose from before a ride begins.

    OEM is primarily financial and scarcely performance realated. Of course, there will be the smaller operations that are looking squarely at rolling resistance, weight and general performance over price.

    Also taking notice of skill sets, we all know where we need to focus on improving and place an effort in it. Challenge is good, since it improves our ride.

    What Trek + bikes had Schwalbes?
    Everything I've seen has had Chupa/XR2s since the beginning

    I know the Trek Roscoe 7 for 2018 has Schwalbe Rocket Rons on it when I bought it.

    Fuel EX last year certainly had Schwalbes.

    There's nothing wrong with 29+, but it's a niche within a niche.

    That said....the Full Staches I've seen had XR4s OE.

    Well,I am 60 yrs old so the main skill set I work on is building the stamina to go riding with the mid 30 yr olds!

    I need to work on hopping my Sherco trials bike first, I would like to ride the Advanced line in some events before I get too old. Shoulder surgery then trialsmastering a event that went off weekend before last has put pedaling onto the back burner.

    Bud and Lou are still going strong after 5 seasons... JJ's are fine for my Jeepin forays, and if I wanna get properly rowdy, the Wildcat or Middlechild will certainly be involved!

    Looks like half of the new fat bikes are 27.5. i don't think jj comes in 27.5, so that explains part of the reason you are seeing less jj.
