Share the post "Loïc’s Specialized Tarmac SL6 Expert"
Loïc Sarret is a former professional motocross and Supercross rider who discovered cycling later in life. But he quickly became passionate about his new sport, and in May 2020, he bought a Specialized Tarmac SL6 Expert Disc, equipped with Shimano Ultegra Di2 and Roval C38 wheels. After a few months, he made some modifications to reduce the weight from 7.7 kg without pedals to 6.9 kg. The result is superb.

« I bought my bike in May 2020, but I quickly upgraded it for aesthetic reasons and because I wanted to save weight, begins Loïc Sarret. Even though I live in Essonne, I regularly ride in the mountains, and I love it. As everyone knows, weight is the most important factor for climbing a pass; we’re talking about the law of gravity! So I started by changing the round aluminum Specialized Expert handlebar for the Aerofly model from the same brand with the Venge stem for aesthetics. This allows for the small winglets between the handlebar and the stem. Then, I changed the Power Arc saddle, chosen after a bike fit, for the same S-Works model with carbon rails and shell. »
Then Loïc moved on to the wheels: « I wanted versatile and lightweight wheels, and tubulars were the obvious choice, he continues. I’m not disappointed, with good efficiency and great feel. So I replaced the Roval C38s with Legend 55 wheels featuring DT Swiss 180 EXP hubs. They’re top-notch! It’s a shame the Roval Rapide CLX weren’t out yet at that time, but they’re in the pipeline with K7 Bikes store in Monthléry.«



« When modifying the drivetrain, I took the opportunity to install Cycling Ceramic derailleur pulleys. I would have liked to mount a derailleur cage with oversized pulleys, but it wasn’t compatible with my medium cage (GS) derailleur, and it’s currently out of stock for the short cage (SS) model. But that remains a planned modification. »

« Ultimately, the bike went from 7.7 kg in size 54 to 6.9 kg, or a round 7.2 kg with the Assioma power meter pedals, he concludes. I made this choice because I plan to buy a Specialized Shiv, and this pedal system allows for easy transfer of the power meter from one bike to another. »
