ADVENTURE²
Your bike should match your vision of the ride, adapting to whatever adventure your trail takes you on. That can mean razor efficiency and instinctive handling to one person, or it can mean floating jumps, railing high mountain corners and pulling up over roots to another.
Make The Mountain Your Playground
Occam LT is the voice in your head telling you that you can push harder, stay off the brakes, and take it that bit further. It thrives when things get steep, fast, and loose.
Choose Your Adventure. Smooth Moves or Rowdy Routes
Adventures can take you anywhere, and Occam is built to keep up. Whether you're chasing flow and speed or seeking out the roughest descents, there's an Occam for your ride.
Progressive Trail Suspension
Occam has always been famous for its climbing ability and that hasn't changed. With around 30% progressivity Occam balances finding grip with composure on the bigger hits. It also works well with coil shocks
Kinematics
Built to charge hard, Occam LT's concentric pivot suspension delivers a controlled, linear-progressive feel when the trail gets rough. Balanced anti-squat and anti-rise keep it efficient under power and stable on the brakes.
Leverage RatioProgressive curve gives great traction and bottomless feel. this also works well with a coil shock
Anti-Squat
Great pedalling efficiency
Anti-Rise
Controlled under braking
Fast and Light Adventure machine
Lightweight and ready for anything, Occam might just be the perfect trail machine for big adventures.
High Performance Materials
OMR Carbon
High modulus, high-strength fibres, and advanced carbon manufacturing techniques let us use less carbon while maintaining strength.
The Same Fast Trail Experience. In Alloy
Using aluminium technologies as advanced as our carbon manufacturing ensures our aluminium bikes are never second-best. For riders who prefer aluminium, our High Polished Alloy is simply the best aluminium frame you can buy, with the bonus of that carbon-look.
Shock Extender - Lightweight Carbon, or Adjustable Alloy
Each Occam is equipped with the perfect shock extender for its purpose. Lightweight carbon for the SL, adjustable alloy for the LT.
Asymmetric Design
The offset frame brace allows us to remove material whilst tightly controlling stiffness and lowering weight. The fact that we think it looks cool is almost irrelevant.
No Compromise Trail Machine
With adjustable geometry, you can fine-tune your setup to match the terrain or your riding style, all without changing parts. Flip the chip, shift the attitude.
Attack the rowdiest trails
Occam LT puts riders in the perfect position to attack the trail. Of course, Attitude Adjust lets you tune Occam LT in a bit to suit whatever adventures you have in mind
Head angel from 63.3º - slack and aggressive for the toughest trails
BB Drop from 38mm - low and stable, perfect for shredding the bike park
Lower standover and deep seatpost insertion lets you choose your size to get your preferred reach
Attitude Adjust - Tune For The Trails
Occam is ready for every adventure, with adjustable geometry that lets you fine-tune your setup to match the ride.
Headset Adjust
The headset angle is easily adjustable using the offset cup. The possibility of regulating +/- 0.75º allows you to slip into a more slack position for steeper tracks or aggressive runs
Attitude Adjust: Change The Geometry In Less Than 15 Seconds
Attitude Adjust lets you tune Occam LT to suit whatever adventure you have in mind. With our new Quick Flip system, changing from High to Low takes just a few seconds. The clever, offset design means you only need to slacken the bolt, using the 6,, hex tool in the rear axle, and pull slightly upwards on the top tube. It takes less than 15 seconds.
Choose Internal or External Headset Cabling
You asked and we listened! We give you the choice of internal headset cable routing or not.
Steep 'n' Deep
Due to the uninterrupted, steep seat-tube all riders should be able to fully insert an astonishing 230mm dropper in their Occam. Drop your saddle right out of the way on the descents, giving more space to move your body and more control. Long travel droppers are the only way!
Simple, Minimal and Packed With Features
Great things don't have to be complicated. The patented I-Line system means the remote lockout is sleek and easy to use. Cleverly integrated tool storage and the bigger and better LOCKR frame storage mean everything you need is right at hand.
Quiet Frame Fundamentals
A quiet bike is a fast bike, and Occam keeps things silent with features that cut out noise and distractions.
Upgraded Frame Protection
Occam is fitted with an upgraded, soft rubber chainstay protector which absorbs chain noise.
Fully Guided Cables
Occam’s internal cable routing eliminates rattling and makes maintenance straightforward. Silicone entry and exit plugs reduce noise even further, while a guided internal conduit ensures clean, quiet cable transitions between the front and rear triangles.

OC Components
OC Components offer better integration than ever before as well as giving many options to find your perfect fit.
Integral Orbea Elements
Clever features, designed to improve your ride.
Fully Loaded Pivot
Rallon's Fully Loaded Pivot (FLP) includes a multitool with 2, 3, 4 and 5 hex keys held securely in place with a magnet while the rear axle holds a 6mm hex key for quick adjustments right at hand.
LOCKR
Enjoy the advantages of our updated LOCKR with easier access than ever. Store tools, lunch or even a jacket easily behind the water bottle mount ready for easy access.
Fully Sealed Bearings
Bearings normally fail due to grime, not overload. We have worked hard to seal Occam's main pivot points. Clean bearings last longer and keep the suspension working optimally when things get dirty.
Second Skin
Occam is ready for a tough life and the replaceable vinyl protection brings new styling options as well as keeping the paintwork looking like new for longer. The beauty of it is that if you get bored of the look, or want to refresh your bike, you can easily remove it and replace it with a different design.
Integrated Chain Guide
Light and simple, the integrated chain guide offers enough protection to make sure you don't drop your chain on the roughest trails.
