did you already swap the crankset to the R7000 model? and new stem with no headset dust cap? What was your reasoning?
Posted over 2 years ago
Simple: Even if I work for Shimano and and ordered the groupset back in 2021, I'm still waiting for the Crank. The R8100 on the contest was a crank that Scampi Cicli lent me. Now I have to ride the available and cheap 105 till my crank will be delivered. Extralite stem is some serious weightwheenie stuff. How this cnc masterpiece flexes and clamps is just scary. The Ritches is 120g heavier but I trust it lol.
