    Widest tires on Jeffsy 27?

    I know the current Jeffry comes with 2.35" tires. Does anyone know what the widest tire the frame can safely handle? I really want a 27.5+ but since they haven't come out with a plus version yet I'm wondering what's the widest I can get away with.

    Neither the 27" or 29" frames say they can work with 27.5+. You can definitely fit a 27.5+ tire on the front of the 29" fork, but I'm not sure about the rear. Looking at my 29" frame I'd say there's probably enough clearance for a 27.5+ tire, but can't be sure. You'd definitely be dealing with a dangerously low BB.

    I get that I won't fit a plus size tire (2.8", 3.0") back there in the rear triangle. I'm just wondering how big I can go, 2.5"? 2.6"? BTW, I'm looking at the 27.5 version of the Jeffsy

    Perfect. That's just the info I need. What tire are you running in the back?

    Right now I still have the original HR2, but I want to switch to the Maxxis Minion DHF or DHR

    Honestly I would rather try a 2,6 tire in the back and in the front 160 or 180 mm 29er air fork and wheel with a 2,4 tire.
    It would make the Jeffsy a beast to ride and I finally could get rid of the stupidly low BB.
    One thing for sure, I won't buy any new bike with low BB anymore.
    It may be great on downhill but hella annoying on uphills.
    I hit the shit left and right all the time and it ****ing sucks.

    My new 2018 JEFFSY 27 CF PRO RACE. The 2.6” width Maxxis Minion DHR II has plenty of clearance. The Maxxis sidewalls are about .5” more than the stock e13s. . The weight and balance of this bike is awesome (much better than my Niner RIP 9 RDO).

    Yeah the low BB is the one geo element im curious how will be, mostly because I already feel like i wish mine was a little higher on my 2011 FSR specialized pitch.

    Of all the comparable trail bikes im looking at I think the Jeffsy has the lowest, other than the new stumpjumper which seems crazy low

    I just measured the bottom of my e13 crank arms (vertical position) and the ground clearance is 6.5”. This is with the flip chip in the high position and with the Maxxis Minion 27.5 x 2.6 tires. For comparison, I also measured the ground clearance on my Niner RIP 9 RDO and it’s the same (6.5”). This is with Maxxis Minion 29 x 2.5 tires.

    Thinking 170mm cranks and 2.6 tyres will resolve the low bb problem.

    Resolve the low BB problem. That's funny. The low BB is a feature on this bike and is comparable to the other "ripper" trail bikes in the category. I am curious how many volume spacers people have in the rear shock when they complain about it being an issue. I found the RS shocks don't have any support without them and will sag too far in the travel going up hill making the BB too low for climbing. I would start there if your BB is too low.

    Didn’t wanna start new thread, talking about tires anyways. E13 tires have amazing grip but I find them slow rolling. Is it just me or others feel the same? If so did they improve over time?

    I have a 2017 XL with 2.8 Nobby Nic tires and tubeless.
    Rim width is 29mm. Tire width is 69mm at 23 psi.
    Those tires roll pretty light and climb great.

    I had to cut off a small part of the rubber protector, because of slight rub.
    Other than that there is still around 7mm space to the chain and seat stays on both sides.

    But I'm not sure if that will work the same on the smaller frames.

    2.6” Maxxis DHF in the front. Plenty of clearance! Love this bike! 👍🙂
