I haven't personally, but I've seen a couple of people who have. I think one was over at mtbr forums with a couple of photos

I'm 82kg, and run 2 volume spacers in my deluxe shock at 225psi. Nice and firm, sits at 20-25% sag, currently my setup for when I ride downhill. Bring it to 210-215psi for normal riding, around 25-30% sag

Is your pump okay dude, or do you huck-to-flat a lot? I can't imagine how it can move at all with that much pressure. Or maybe you like it hard (I know that's what she said), no problem with that, I am just asking.

I am 85ks and run with 160psi, no bands which equals a ~32% sag and even with this I am unable to use full travel. Which is no wonder because with my settings and weight it bottoms out at 7500N which is more than most other frames ( a Speci Enduro or a Bronson goes up only until 6000N-ish on 30% sag. This is the force btw I am capable of putting to the rear wheel of my Jeffsyca too with no jumping so I could use full travel on those bikes with my style. Btw the Nomad 3 on 30% has the same 7500N bottom out force and that is not a trail bike either.)

225psi takes the unbelievably high 11000 N to bottom it out (not counting the bands which add to the progression), which is almost twice the force I'd bottom out a Bronson for example.

Yeah, your pump seems to be okay, 82kgs and 225psi outs it to 21% sag.

For anyone considering the Gabaruk 10-50 11sp cassette, and wondering if the rear mech can handle the range.
For the X1 on the MY17 AL One, it is a no go.
If I make the chain "short" enough, to have at least a little tension on the chain when in the 10t. Then I max out the mech at full compression. And I'm still at 150mm travel, so 160mm would be worse.
Although there's not a lot of chaingrowth, it's enough to be too much in this instance.

On the other hand, if I make the chain long enough, to have just a very small amount of movement left in the mech at full compression. Then there's no tension on the mech, so the chain grinds on itself. No amount of B-screw adjustment can fix this.
Well, their cage will fix the issue. I had just hoped that I wouldn't have to extend my mech.

The cassette does seems to be surprisingly good quality though.
And doesn't weigh half a kilo, like the GX Eagle does.

Hello dear jeffsy owners. I've been looking to upgrade my 29er hardtail to playful trail bike that can take lighter side enduro/dh too (no big hits) and seems like jeffsy is best option. 29 wheels feel too big on technical slow stuff, tight turns etc. I think my height 5'6 has effect on that too.

Only thing concerning me is pedaling effiency. Guy on link below sure makes the suspension sound not-so-efficient if bike shakes you around every root. My trails are literally full of big roots as i can show on video clip later on. Maybe his suspension isn't set right? I really need a bike that i can pedal through root sections without bouncing around as thats the reason im not enjoying hard tail on first place

Here is what my trails consist of. I can tell you this isn't fun on hardtail after riding couple hours Big Grin

Also, what kind of suspension you think is best for this kind of terrain. 27 AL with fox rhytm etc or 27 AL Comp with rockshox? Or do i need to save more money for even better setup (or bike). I don't want to be upgrading later like i had to do on my hardtail.

How do you like this setup compared to the e13's and does the rear ever rub?

Made a huge difference for me. So much faster now. The e13 felt like i was dragging an anchor.

Obviously the rear doesn't grip quite as well, but I don't mind the rear being a little loose. I'll use the e13 for any shuttle/uplift days.

Sorry, I should've been more specific. Wondering whether or not you made a good decision to go with the 2.6's, and if you have any marks on the seatstay/chainstay. Mine are already dinged up from rocks and mud with the 2.35 and it's only a couple months old. Same bike btw Beer

So how many of you carry a spare derailleur hanger when you ride. I have been but it just dawned on me that without a spanner I am not going to be replacing it out on the trail anyway. It's kind of weird that YT didn't make a hanger that attaches with a hex bolt.

Does anybody know what happened to the "Size doesn't matter" video? Is it still available somewhere?

You can use your axle to get it off. Just thread it in from the opposite side.
I know it's from a Capra, but it applies to the Jeffsy as well Smile

That's awesome! I was wondering if that would work but I hadn't tried it. Good to know.

It’s been gone for a while, I liked that one. Not sure why it got pulled offline.
