I'm trying to decide on tires for my upcoming SS build. The 29-4 looks like it might be a sweet rear tire. The Bonty Jones ACX has always hooked well in my area (especially on wet slick roots and such) and the 29-4 looks to be their new version of that tread design.

Any one got a good bit of time on one of these? Would definitely like to hear from some East Coast riders if possible.

Got a few rides on mine before winter hit. Seems to be a different tire than the ACX was. I'll be getting back out again on them soon now that our trails are drying out.

As a rear tire on an SS rig? I wouldn't go there, but I don't have trails like yours either. I'd maybe consider a FR-3 rear/ 29-4 front for a grippy set of SS tires. But that's me.

I was actually thinking the other way around, but I see where your coming from there. The FR-3 probably would roll better.

I'm looking at these two Bonty tires, the Ardent 2.4, and Purgatory Control 2.2 & 2.4 (maybe Captain Control 2.2 for rear).

I would like a tire that doesn't have terrible rolling resistance, but my main interest is something that will hook up on climbs and good volume. Spinning out on a SS blows, besides being a clyde, gravity seems to play in my favor on downhills. :)

I will be riding some rolling trails though, and I don't want the tires to hold me back too bad.

My previous SS tire combo has always been a Rampage reversed on the rear and correct rotation Rampage on the front.

Ha ha! Well, if Rampages worked well for you, the 29-4 definitely rolls better than those tires.

I don't have enough trail time to give you judgment on climbing in mash-mode, or on fast cornering on hard pack, but so far they seem like a great pattern for loam and loose, rocky terrain.

Thanks for the input Mark, I'll be watching for you thoughts later on for the 29-4.

The Jones ACX has been by far my favorite rear on my geared bikes and I have a new one that may go on the SS for the rear tire at first. If only there was a 2.4 version of that tire!!

I have used the 26" version of the 29-4. Its angled knobs not not holdup as well as the square blocks of the ACX on rock and roots and more so in the wet. The FR-3 (and 29-3 2.25) is great in the dry and a bit sketchy descending wet roots/rocks.

Look at the Panaracer CG XC 2.25 for drier conditions.
Schwalbe Nobby Nic for looser or wet.

This makes sense to me so far as I have had the 29-4's out on trails. This was where I was leaning towards as far as my opinion on them. Since you commented pretty much exactly my inclinations so far, I figured I'd let on to that.

I agree that the old ACX would be stellar as a 2.4 incher which would probably work a treat in techy terrain, wet slippery stuff, and loose rocks.

But that isn't any surprise really. Look at any trials tire worth its salt and you'll see right where the ACX gets its grip. Or look at most any motocross tire for that matter.

Square blocks. Hard to beat the simplicity and functionality of that shape for a grippy, aggressive tire, me thinks. :)

I've been using the 29-4 on the front for a few months. I like it, definitely rolls faster than the hugeness would imply.

My SS is sporting a 29-3 front, and I will be trying a 29-2 in place of an XDX on the rear tomorrow morning for the first time. The 29-2 is a good bit lighter - we'll see how the traction is. I have used ACX front and rear with great success on this bike.

Trails are typical Socal - rocks, loose over hard, etc.

I am hoping 29-4 will be my new Stout. It is reported 200 grams lighter (Team Issue) each, and it sure looks to have the potential to roll well.

The Stout is basically a square block tread. The 29-4 is not. See the comments above.

I have had a Bonty 29-4 mounted on the rear of my SS for about 10 - 12 weeks and love it. Living in the AZ dessert I cannot tell you how it works in the wet or on roots etc but it just flat out grips on rock and sand. My initial concern with the 29-4 was that the sidewalls felt much thinner than my FR3 (or the UST and DH tires I run on my 26" bike) but so far so good.

Keep thinking that way.

The 29-4 is massive, taller than a Purgatory. You will have a hard time fitting it unless Steve did something different to the chainstay yoke.

The FR3 is much more capable on dry rock and loose terrain in my experience riding them back to back.

29-4 rolls better.

Personally for a bike where traction is important, I would just run an FR3 front and rear. This is what I run on the Jones and it's killer....for our terrain. In loamy terrain, who cares, everything hooks up.

I would agree that the FR-3 rolls and grips really well in the dry, but I think the OP is on the East Coast where wet roots and rocks are more common. There I feel the FR-3 would slip more easily due to the center rib design it has.

And as for loamy terrain- Not "everything" will hook up there. We get loamy conditions a lot here, and if you run a lower tread style, or something with tightly spaced knobs, you will experience poor traction. At least around here. YMMV.

I'd be hard pressed to give up the Rampage up front. I've yet to find a better tire for this area.
On my previous 38mm rim I completely agree! However on a 28mm rim I still like it, but it doesn't have the same cornering traction IMO.

Have you tried it on yours, and if so did you have to put the sliders all the way back?

Shiggy- So in your opinion which of the mentioned tires would have the best forward bite in dry and wet rocks/roots?

Peace.

Will the 29-4, then, not hook up and land drops like the Stout? Except for weight, I have loved the Stout, but obviously, as we've noted before, it's gone. I need something for harder intermediate/lighter black diamond runs at Mammoth and such.

I for sure won't be looking to the Dissent for that. Too heavy for anything I ride (at least until I can hit the lotto and get a PBJ).

I ride tubeless exclusively on trails, and the Bonty TLR family have been excellent, even on Flows.

I got a new Superfly 100 and before I left the shop I changed out the tires. Originally, my plan was to use the 29-4 on the back and the FR3 for my front, but after seeing the FR3 (FR means FreeRide) it in person, it's pretty heavy. I decided to use my old standby for the front - the Panaracer Rampage. Similar pattern, lighter, and proven to work great.

It fit, but would rub under hard cranking at 16.4" It is the same width as the Purgatory 2.4, but taller. I had no trouble fitting an FR3 2.25 at 16.4" It would fit best around 16.7" as that is where there is max clearance. Overall, I think you are better with a 2.2 ish tire back there, especially if you will want mud clearance.
