Pole Stamina 140 Up Close At The Sea Otter

by 6

We got up close and personal with the new Pole Stamina 140 at today’s Sea Otter Classic in Monterey, California.

Previously dubbed the Bushmaster, apparently that name was in use, so Pole logically chose to name it in line with the existing Stamina 180. It features the raw machined aluminium look of the Pole Machine although, unlike that bike, which is machined in two halves and then bonded and bolted together, Pole is confident enough in its construction that it has removed the bolted aspect of the frame.

The Stamina 140 is a 140mm all-round fun trail bike with 29in wheels and pretty modern geometry, with 64°/78° angles and a reach of 500mm for a size large.

Steep and slack.

This is the first time we’d seen one in the flesh, and designer Leo Kokkonen was happy to show us some of the finer details. He was particularly proud of the weight (13.2kg/29.1lbs) and the lateral stiffness (very)…

If you’re going to machine things, might as well get a logo in.

Unlike the Machine, the Stamina is symmetrical

Leo reckons that most riders would get on just as well on the bigger Pole Stamina 180, but admits that some riders aren’t going to be going flat out all the time and might enjoy the slightly shorter travel.

Complicated, yet simple

Compared to the Stamina 180, the 140 has enlarged bearings, which allow for shorter linkages due to the larger bearing diameter. The swingarm pivots are three-piece too, with a keyed axle much like a crank. This allows easy replacement of, say, just a single side of a rear end if you damage it.

The linkages have been shortened thanks to the bigger pivots

Huck Norris 2.0 Prototypes spotted

Pole and Huck Norris, the rim protection system both share a designer in Leo and he had some prototypes of the new Huck Norris system he’s working on. The new version will have dual (or even triple) density foam to improve rim protection and reduce bounce when bottoming out. There are no release dates yet, and Leo reckons there’s still another season of testing to go, but you heard it here first…

The new system will have tougher foam to provided a more graduated bump resistance.

The system might even have three layers of different foam. The cutouts may change too.

Chipps wasn’t around for the dawn of mountain biking in the UK, but he likes to claim that he arrived in time for second breakfast (about the time he shows up for work, then…) starting in the bike trade in 1990 and becoming a full time mountain bike journalist at the start of 1994. Over the subsequent quarter century, he has seen mountain bike culture flourish and diversify and bike technology go from rigid steel frames to fully suspended carbon fibre (and sometimes back to rigid steel as well.)

His riding style is best described as ‘medium, wheels on the ground, trail riding’ though he’s been spotted doing everything from endurance downhill racing to 24 hour cross country racing. He favours mid-travel trail bikes and claims to be wheel-size, gear, brake and tyre agnostic. In fact, his garage spans most bicycle flavours, taking in steel hardtails, carbon trail bikes, even a mountain bike tandem, along with road, touring and gravel/cyclocross bikes.

While he’s happy to chat about bikes all day, his real interest is in the people and places that bikes can introduce you to and he talks as fondly about the trails he’s ridden and riders he’s met as the bikes that took him there.

    I kow a guy who bought one of these and it literally fell in to two pieces as the joint where the frame is glued together completey failed. I hope they get this sorted as it looks like a geat bike to ride.

    @pmurden did he have one of these new non-bolted only bonded models? All the earlier Stamina have bolts and glue holding them together. Did the bolts snap too?

    SA angle looks very steep, which isnt a bad thing

    I find it extraordinary that they’ve managed to use this method to get a 29lb bike. When you look at tube wall thicknesses on a normal welded frame, it’s hard to imagine that they could get machining close.
    I don’t know whether I’m super-impressed, or a little worried about their longevity. I really hope they succeed with this.

    @AlexSimon I believe they use a different aluminium alloy for the machined frames, stronger and stiffer one. But I agree it will be interesting to see how these frame fare in the long term.

    @pmurden Sorry mate, but sounds like BS. The Stamina frames (*i think) haven’t started deliveries yet. If it’s one of the earlier, first gen Machine models then have the bolts snapped? I’d be surprised.
