For the cyclist who loves the feel of a cable-operated derailleur, often goes away on trips or holidays and doesn't want to depend on a charger. It suits someone who wants carbon wheels and a race frame while keeping mechanics they can maintain themselves.
OCLV carbon, Trek's signature. OCLV has been Trek's in-house process since 1992: heat and pressure compact the carbon layers so that almost no voids remain between them, the usual weak point of a composite frame. On Trek's scale, the 500 of the SL 5 Pro marks the first road tier and the 900 of the SLR models the top; as you move up, the amount of material needed for a given stiffness decreases. Trek lifetime warranty on the frame, as on all OCLV models.
| OCLV 500 (SL 5 Pro) | OCLV 900 (Madone SLR) | SL / SLR difference | |
| Level | Entry point to Trek road carbon | Top of the carbon range | Identical tube shapes |
| Construction | OCLV layup with more fibre | 3D moulding, reduced overlaps | The 900 claims up to 20 % more strength than OCLV 800 |
| Reference bike | Madone SL 5 Pro: 8.44 kg (ML) | Madone SLR 7: 7.52 kg (ML) | 0.92 kg, of which 271 g on frame + fork |
| What it means | Budget focused on the carbon wheels | One-piece carbon cockpit, aero bottles supplied | The SLR frameset is mainly justified for racing |
Put simply: the SL 5 Pro keeps the OCLV 500 frame of the SL 5 and invests where the gain is felt most, in the wheels. A 48 mm carbon rim reduces rotating mass and improves the way it cuts through the air; the SLR frameset would only save about 270 g more.
Mechanical 12-speed Shimano 105 remains precise and light in use; a cable can be replaced anywhere, whereas an electronic fault needs a diagnosis. On a trip to the Pyrenees or the Alps, that is real peace of mind, and the 11-34 leaves you something in reserve on long climbs.
Should you ever change your mind, the frame is designed to accept an electronic drivetrain thanks to its compatible routing and UDH hanger. In the meantime, the separate stem lets you change the reach easily, and the threaded T47 bottom bracket remains simple to service in the workshop.
| Model | Carbon | Drivetrain | Wheels | Weight (size) |
| Madone SL 5 | OCLV 500 | Shimano 105 mechanical 2x12 | Paradigm 23 alloy | 8.64 kg (ML) |
| Madone SL 5 Pro | OCLV 500 | Shimano 105 mechanical 2x12 | Aeolus Elite 48 carbon | 8.44 kg (ML) |
| Madone SL 6 | OCLV 500 | Shimano 105 Di2 2x12 | Aeolus Elite 50 carbon | 8.16 kg (ML) |
| Madone SL 6 AXS | OCLV 500 | SRAM Rival AXS 2x12 | Aeolus Elite 48 carbon | 8.11 kg (ML) |
Our take: compared with the SL 6, you keep mechanical shifting and 48 mm wheels instead of 50 mm, for 280 g more. If wireless electronic shifting tempts you, the SL 6 AXS weighs 8.11 kg.

LVR sizing advice Between two sizes, the smaller one is often right on race geometry: the two-piece cockpit then lets you lengthen or shorten the stem without changing the handlebar.
