Carbon aero road bike Trek Madone SLR 7 matte carbon grey: a rouleur into the wind, Ultegra Di2, 7.52 kg in ML

Trek Madone SLR 7 Carbon Smoke: ride fast into the tramontane

The Trek Madone SLR 7 Gen 8 is an aero race bike with an OCLV Series 900 carbon frame, built with Shimano Ultegra Di2 2x12 and 51 mm Aeolus Pro 51 wheels, for 7.52 kg in size ML. This colourway is reserved for sizes L and XL, intended for riders from 179 to 199 cm. The Matte Carbon Smoke/Prismatic Pearl finish lets the carbon weave show through a matt smoked grey, enhanced by prismatic pearlescent highlights.

Technical specifications

Who is it for?

For the solo rider who racks up long rides on the flat, often into the wind, and for the tall cyclist who trains alone and wants to hold a high speed without wearing themselves out. It is aimed at intensive training as much as at fast, rolling sportives.

The LVR workshop view

OCLV carbon, Trek's signature. Since 1992, Trek has pressed its fibre sheets under heat and pressure to drive out micro-voids. Each step up the OCLV range reduces the amount of material needed for a given stiffness, and the Series 900 of the Madone SLR 7 is the pinnacle: 3D moulding, fewer sheet overlaps, and strength up to 20% greater than OCLV 800. The result: 796 g for the painted frame in ML and the Trek lifetime warranty.

Put simply: with the same groupset and wheels, the step from the Madone SL 7 to the SLR 7 comes down to the frame and cockpit. You save 350 g on the complete bike in size ML, and the one-piece Aero RSL bar/stem replaces the separate bar and stem, at the cost of less flexible position adjustment.

The Full System Foil principle consists of designing the tubes with the bottles in mind, since bottles disrupt the airflow on most bikes. On the SLR, Trek supplies RSL Aero 595 ml bottles and cages that are integrated into this profile; round bottles can still be used if you prefer your usual set-up.

On the open roads between Béziers and the sea, the sea breeze and the tramontane often blow across the road: the 51 mm rims remain a good compromise, more stable than 60 mm profiles while keeping useful momentum on the flat. The IsoFlow seat tube filters out vibrations from the rough tarmac of the plain roads.

Which Madone should you choose?

Our take: for a strong rider on the flat, the aero gain of the Gen 8 frame matters more than weight: the SL 7 and SLR 7 share the same shapes, and the 350 g difference is felt mainly on climbs. The SLR 7 AXS adds a power meter that is useful for training.
