Bombtrack Beyond+ ADV 29+ expedition mountain bike ventures even further

Last year Bombtrack’s 27.5+ Beyond+ had already crossed North & South America with Tales on Tyres, and tackled the unsupported Tuscany Trail race with Clem Shovel. As a loaded expedition off-road touring mountain bike it was an affordable & capable ride. But Bombtrack knew they could do it better, so now the Beyond+ gets Advanced for 2018…

What’s new in 2018?

Building on the success of the first generation Beyond+, Bombtrack tweaked the bike into a bigger wheeled 29+ bike. Keeping the same general concept of the bike, the 4130 double butted chromoly Beyond+ ADV gets larger and fatter wheels to roll over even more challenging terrain in 2018.

The other big change on the Beyond+ ADV is a new full carbon, tapered steerer monocoque fork. With the bigger wheels & giant 3″ tires, Bombtrack wanted to trim weight back, managing to still drop 700g off last year’s smaller bike.

And not just any fork can suit a 29+ adventure bikepacking machine, so the ADV includes anything cage mounts down both legs of the carbon fork, and even internal routing for a dynamo wire if you want to add a dynamo hub.

Tech details

The new ADV also features a stealth dropper post routing port in the downtube. So now you can get down, even with a loaded bike. (Although droppers and bikepacking saddle bags don’t really mix well.) The bike keeps routing external for simplicity and durability, and also adds Rohloff compatible stops.

The bike already had tons of braze-ons to mount several cages and whatnot. But now it gets even more inside & out of the main triangle plus the rack mounting points at the rear.

Complete bike build

The ADV features 29+ wheels with massive 45mm internal, tubeless-ready WTB i45 rims, and wrapped now with 3.0″ TCS tubeless ready WTB Ranger tires. Of course the big 29+ bike includes front & rear thru-axles and Boost spacing.

A new SRAM GX Eagle 12-speed drivetrain keeps you moving with its super wide 10-50 cassette paired to a 32T chainring. The frame features a standard threaded bottom bracket, IS brake mount out back & post mount on the fork, and an oversized seatpost so you can get a proper dropper.

The bike build also includes the Jones Loop handlebar, specially developed for control & comfort through multi hand positions, paired with short 80mm stem.

The complete steel Beyond+ ADV will sell for $3100/£2500/2600€, with a claimed weight of just 12.8kg for a medium. It is available in a four size range (S-XL).

Geometry

The new Beyond+ ADV expedition mountain bikepacking killer will be available from the January 2018 through your regular Bombtrack dealer. Two versions of the 27.5+ Beyond+ also carry over in 2018, one that shares the same carbon fork as the ADV.

They’ve been killing it in the fork department.

Nice looking bike!
Brings up a question I’ve wondered about lately….. Why have a 50 tooth rear cog and a 32 tooth front? Back in the day having 4 teeth less in the front for your “lowest” gear was a little slower than walking and very adequate, has this changed?

Excellent point. Funny thing is most people I know think that 32t ring is way too big to pedal uphill with 50t cog. Many in my area want 30, 28 or even 26 tooth chainrings! It seems most Mtb bikers have lost the ability to try harder or simply walk uphill when the trail becomes difficult.
Nobody wants to spend the time to develop their climbing skills anymore. It’s too much work and doesn’t have the instant gratification most people desire. Instead everyone is “all about the downhill” or “just wanting to send it”

Cool bike though!!!

It is a not a classic MTB.
You can use it as a MTB but is more for Bikepacking or Loaded touring, explorer MTB.
I think it make sense the need of smaller cogs in front (when you are loaded).
I will try it 🙂

@Jimmy: because the bike is meant to be ridden with a load. Heavy bikes need lower gears.

Tire sizes are much bigger than (my guess) the 26×2.1″ tires from back in the day. 32/50 on a 29+ is about 19 gear inches. 26/30 on a 26×2.1″ is about 22 gear inches. Not far off. Close to walking pace for either gear ratio scenario.

I enjoy riding bikes, not really walking them. If I can clean a super steep technical section at less than walking pace, I’m much happier than if I have to get off and push my bike.

This hasn’t changed since my first mtb, which had a 24×28 low with 7 speed thunbshifters.

Now, with my 29+, a Minnion in the rear, and a 30×46 low, the things I can’t climb are few and far between.

Agree with you here. 24-28 worked for me when I was twenty lbs lighter and ran 450gram XC tires on a light “race” bike. Now my bikes use grippy tires that weigh twice as much and I roll over much more gnar. When hauling a chain saw my 30-46 and even 24-36 are not enough. Bike packers often haul a ridiculous amount of gear along with a six pack of carbs.

Yeah, I don’t understand why anyone would need a 32 tooth front when you have a 50 rear. I’m running a 38 front and have never needed anything smaller. If I was going to do a multi day mountain trek I might change it to a 36. But 32? Not on my 27.5.

36/50 on a 27.5X2.8 is 20.5 gear inches. 32/50 on a 29×3.0 is 19 gear inches. Just a bit lower than your example. The comparison is tighter if you are not running big tires on your 27.5. Sure, maybe lower gearing than you prefer, but not off by much.

Even though I have no place to properly ride it I would love to have that bike. Makes a lot more sense than any fat bike or full suspension machine.

Probably like every 29” hardtail, but have a look at the maximum tire clearance and the frame geometry. We tried to tap the full potential of the Boost standard when designing the Beyond ADV.

Totally, if they wanted to make an adventure bike with a lot of braze-one, they should have built a single triangle bike.

Astonishing bike. Bombtrack is on fire.

I think what a lot of people don’t get is that bikepacking is often done in remote terrain with varying ‘trail’ conditions. Where I live in the Swiss Alps, mountains are shockingly steep (the road out of my house has a warning sign for 26%) and as you become more fatigued, it gets more difficult to climb. When I started bikepacking, I was a serious singlespeeder and I still dropped from a 32 to a 30…. there are times that I wish I had a 28t…. even with a 1X12, 50t rear cog. Generally, I find myself using the gears at either end of the cassette, more so than the middle. Just sayin’.
