Origin

The Occam is Orbea's quiver-killer trail bike. Because 'trail' means different things to different people, Orbea split the 2024 model into two distinct bikes sharing the same frame: the fast, pedaly SL (Super Light) and the aggressive, mini-enduro LT (Long Travel). Gen 3 (2020-2023): Moved to asymmetrical frame design and 29er only. Offered in 140mm standard and 150mm LT versions. Gen 4 (2024-present): Formal split into Occam SL (140/140mm, remote lockout) and Occam LT (160/150mm, adjustable geo). Added 'Lockr' down tube storage.

Specifications

Frame: Orbea Monocoque Race (OMR) carbon, or hydroformed aluminium (H-series). Asymmetric design with right-sided strut, Lockr internal down-tube storage and integrated multi-tool in linkage. Straight seat tube allows up to 230 mm dropper insertion on all sizes.
Weight: kg
Drivetrain: Spec varies by trim: Shimano Deore / XT to SRAM GX / X0 / XX Eagle Transmission AXS 1×12 (M10 trim: Shimano XT / SRAM GX Eagle)
Brakes: Hydraulic disc, Shimano MT201/Deore to XT 4-piston or SRAM Level/Code; stock 180 mm rotors (reviewers advise larger rotors for long descents)
Wheels: 29" Oquo MC32TEAM (carbon trims) / Race Face AR30 alloy, Boost hubs

The verdict

+Strengths

Clever, functional frame: Lockr internal down-tube storage, hidden multi-tool, clean cable routing that prevents chafing.
Two genuinely distinct bikes from one frame — SL is a lively, efficient climber, LT is composed and confidence-inspiring on the descents.
LT delivers tons of traction from a sensitive, pedal-neutral rear suspension; SL carves tight corners fast through flowing trail.
Intuitive, accessible handling that feels good from the first ride.
M10 build (~€5,999) widely cited as the best price-to-performance point in the range.

−Weaknesses

Stock 180 mm rotors overheat on long descents — reviewers recommend upgrading to larger discs.
SL's shallow-tread, lightweight Super Race casing tires lack traction on loam and are puncture-prone.
Chain slap against the shifter cable caused damage after minimal testing; upper seat stays left unprotected by the frame film and mark easily.
SL reaches its limits quickly on rough terrain and rewards a clean riding style; even the LT gets overwhelmed on the very roughest trails.
LT is heavy (~14.6 kg in L) for a 150 mm trail bike, blunting climbing snap versus the SL.
