The Trek Madone SL 5 Gen 8 combines an OCLV Series 500 carbon frame with the aerodynamic shapes of the SLR models, a mechanical Shimano 105 2x12 groupset and Paradigm alloy wheels, for 8.64 kg in size ML. It is the most direct way into the current Madone, the bike that now brings together at Trek the lightness of the former Émonda and the speed of the former Madone. The Era White colourway dresses the frame in a clean, bright white that is understated and timeless.

For the rider who has spent two or three seasons on an aluminium bike and wants to make the move to carbon with a proper race frame. It also suits anyone torn between a climbing bike and an aero bike: this Madone does both, with a more aggressive position than a Domane.
OCLV carbon, Trek's signature. Since 1992, Trek has moulded its frames in OCLV, a carbon whose sheets are pressed and heated until all internal air pockets are eliminated. The series number reflects how refined the lay-up is: the higher it goes, the fewer fibres are needed to reach the target stiffness. The Madone SL 5 gets OCLV 500, Trek's entry point into road carbon, but with exactly the same tube shapes as the SLR models, and the Trek lifetime warranty on the frame.
| OCLV 500 (Madone SL) | OCLV 900 (Madone SLR) | SL / SLR difference | |
| Level | Trek's entry-level road carbon | Trek's most advanced carbon | Same frame design, same aero |
| Construction | OCLV process, slightly more material | 3D moulding, fewer overlaps | OCLV 900 up to 20% stronger than OCLV 800 |
| Reference bike | Madone SL 5: 8.64 kg (ML) | Madone SLR 7: 7.52 kg (ML) | 1.12 kg, including 271 g on frame + fork |
| What it means | Separate bar and stem, easy to adjust | One-piece Aero RSL carbon bar/stem | The rest of the gap comes from the wheels and groupset |
Put simply: on the SL 5, the difference from an SLR is measured on the scales, not in the wind. The aerodynamic profile is the same; you are simply carrying some 270 g more on the frame and fork, a gap that only a very fussy climber will notice.
Moving from aluminium to this frame is above all about gaining liveliness: OCLV carbon filters vibrations better, and the IsoFlow opening in the seat tube provides vertical compliance that the aero frames of the past lacked. Trek claims up to 24% more compliance than the Émonda; you feel it on the rough roads of the Biterrois.
The 50/34 paired with an 11-34 cassette is sensible for a first race bike: it lets you keep up with a group on the flat and climb the hills of the Minervois without straining. The 23 mm Paradigm alloy rims, Tubeless Ready, are tough and not very sensitive to wind; they are also the first thing to change if you want to upgrade the bike.
| 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 7 | OCLV 500 | Shimano Ultegra Di2 2x12 | Aeolus Pro 51 carbon | 7.87 kg (ML) |
Our take: the SL 5 Pro adds carbon wheels for 200 g less, the SL 6 moves to Di2 and comes down to 8.16 kg. The SL 5 remains the least expensive way to get the same frame as the whole SL range.

LVR sizing advice The Madone geometry is that of a race bike: between two sizes, the smaller one gives you a more tucked position, the larger one more reach. Handlebar and stem follow the frame size.
Source: Trek size guide. Bike fitting available in our Béziers shop. |
| A good first carbon bike? | Yes: a current race frame, a simple drivetrain and manageable maintenance. |
| More aggressive than a Domane? | Yes, the position is lower; the separate cockpit lets you raise it a little. |
| Wider tyres possible? | Up to 32 mm measured, compared with 28 mm as standard. |
| Aero bottles supplied? | Not on the SL models: the RSL Aero bottles are optional, and round bottles fit fine. |

The LVR Cycles verdict The simplest Madone for discovering carbon: you get the Gen 8 aero frame without paying for electronics. We recommend it to those who want a serious race bike and plan to upgrade it.
