For a smaller rider, woman or man, who wants a properly proportioned carbon race bike, with no overly wide bar or excessive reach. It also suits a young racer who is already fit and wants a race bike in their size.
OCLV carbon, Trek's signature. Trek has made its carbon frames using the OCLV process for more than thirty years: each fibre layer is consolidated in a heated mould under pressure so that no micro-bubbles remain. The higher the series, the more optimised the lay-up and the less carbon is needed to withstand the same loads. The Madone SL 6 stays with OCLV 500, with a painted frame of 1,054 g in ML, and benefits from the Trek lifetime warranty.
| OCLV 500 (Madone SL 6) | OCLV 900 (Madone SLR) | SL / SLR difference | |
| Level | Entry-level carbon in the road range | Trek's top-end carbon | Identical aero, only the weight changes |
| Construction | Proven OCLV process, more fibres | 3D moulding, fewer overlaps | OCLV 900 up to 20% stronger than OCLV 800 |
| Reference bike | Madone SL 6: 8.16 kg (ML) | Madone SLR 7: 7.52 kg (ML) | 0.64 kg, including 271 g on frame + fork |
| What it means | Electronics and carbon wheels at this price | One-piece Aero RSL cockpit, Ultegra Di2 | The SLR is aimed at racing and the mountains |
Put simply: with the SL 6, Trek prioritises electronics and carbon wheels over OCLV 900 carbon. For most riders, instant shifting and 50 mm rims pay off more day to day than 271 g saved on the frameset.
On a small size, proportions matter as much as quality: a 36 cm handlebar suited to narrow shoulders, a short 80 mm stem and Di2 levers that need little force to shift. That is a real advantage for small hands, especially on long descents.
One point to watch: a light rider feels crosswinds more on 50 mm rims. In strong wind, keep a firm grip in exposed areas such as the coast or the plateaus of the Minervois; a shallower pair of wheels can complement your kit if you often ride in the wind.
| Model | Carbon | Drivetrain | Wheels | Weight (size) |
| 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) |
| Madone SLR 7 | OCLV 900 | Shimano Ultegra Di2 2x12 | Aeolus Pro 51 carbon | 7.52 kg (ML) |
Our take: in XS, the SL 6 keeps the same 50 mm wheels and the same Di2 as the larger sizes. The SL 5 Pro, with 48 mm wheels and mechanical shifting, weighs 280 g more in ML.
