ORBEA OCCAM TR M-LTDPrice: £5,599.00 // From: Orbea, orbea.comTested: Two months

Back in 2015, Orbea announced that its Occam trail bike was being split in two. Gone was the 100mm travel, cross-country angled machine of yore, and in its place are two very different beasties. The first is a 27.5in wheeled, 140mm bike – the Occam AM. And the second is this, the Occam TR – a 29in, 120mm high-speed trail monster.

First impressions are clear: this bike is light. The XL model I tested weighs in at a scant 24.7lbs without pedals, which puts it in the same ballpark as many cross-country machines, never mind trail bikes. The weight saving comes courtesy of a carbon-high construction, and a large smattering of the nicest kit that money can buy.

Let’s talk about the frame, first of all. Light, yes – we’re told that the large frame weighs less than 4.4lbs, without the shock. There are no pivots at the rear dropout of the carbon frames – instead, Orbea uses what it calls UFO technology, which is essentially another word for ‘bendy seatstays’. The inherent flex in the stays is apparently equivalent to 5kg at the shock, or around 1% of the total spring required once the shock is up to pressure. So pretty much unnoticeable. The frame is comparatively long, and low – there’s a 68° head angle, and a 74.5° seat angle to keep things capable on long climbs. The reach on our XL model is a creditable 472mm – and to aid that reach even more, there’s a Race Face

Turbine 70mm stem, and Race Face Next SL carbon bars in a 740mm width. These are attached to a Fox 32 Float with a custom tune – yes, the photos say Fox 34; that was a stickering error at the factory apparently – and the boosted dropouts front and rear are host to some very swish DT Spline wheels, shod with an Ardent on the front and an Ardent Race on the back.

Drivetrain-wise, 1x11 is the order of the day on our test bike, thanks to a mix of XTR shifter and mech, with an XT 11-42 cassette (they don’t make an XTR one with a 42 sprocket), and a Race Face Next SL carbon crankset; ours came with a 28T ring. And stopping is also courtesy of XTR – Shimano’s Trail variants are mated to 180mm and 160mm rotors front and back.

The RideFirst up, an admission. The test period was December, in Yorkshire. So before I did anything else, I swopped the tyres for something more suited to the terrain around here – a Specialized Purgatory on the back, and a Maxxis Shorty up front. I have no particular complaints about the Ardent/Ardent Race combo, but they’re definitely Summer Spain rather than Winter Yorkshire.

The bike fitted pretty well. That 70mm stem conspires with the generous reach to produce a very comfortable feeling bike out of the saddle or in it – although I’ll pull Journalist’s Prerogative at

this point, and say that I’d have liked 20mm more on the bar and 20mm less on the stem. But that’s something that can be tweaked at the point of sale if it matters to you.

As soon as you turn a pedal, it’s extremely impressive how well the rear suspension works. There’s very little bob, even when climbing out of the saddle, and to be honest I kept the shock open most of the time, only resorting to the ‘trail’ setting on particularly pedally climbs. The steep seat angle meant that the front didn’t get too wandery when the trail turned steeply upwards, and the light weight was certainly a boon. This is, gratifyingly, a bike that rides its weight when pointed upwards.

But what of the descents? The numbers on the Occam TR are definitely more ‘trail’ than ‘enduro’, but even so the bike impressed hugely. It was definitely in the ‘agile’ camp – short chainstays and longer front centre aside, it rewarded line choice more than a ‘barge through’ approach, but it was capable of lightning-fast direction changes, and once I was used to the handling, it screamed through corners and twisty sections with aplomb. As a heavier rider I could

make the Fox 32 fork struggle somewhat when cornering at speed and in certain technical situations; I’d love to see what a stiffer Fox 34 or a RockShox Pike up front could do. I have a sneaking suspicion that it’d make for a quite terrifyingly competent machine, perhaps at the small expense of some of that climbing prowess.

And while we’re on (very minor) downsides, although the thick, Boosted, asymmetric chainstays make the back end beautifully stiff, they meant that I experienced a certain amount of heel-rub, although I don’t ride particularly heels-in. It’s not a major gripe though; it’s something which would be easily sorted with a judicious bit of helicopter tape, or some less chunky shoes (I principally rode in chunky Shimano AM45 or AM9s).Overall: This is a lightning fast, beautifully appointed, extremely pretty, top-end trail bike. It’s not one for the big-hucks enduro brigade, sure, but if you like going up as quickly as you like going down, you’ll be hard pressed to find better. Barney
