henry510 says:

did you already swap the crankset to the R7000 model? and new stem with no headset dust cap? What was your reasoning?

Posted almost 2 years ago

ianiscaratti

ianiscaratti says:

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.

It rides amazing like expected but I haven't been on cx tires since last winter (ca. nov 2021/ 7 month ago). They terreno mix drift very predictable on trails and gravel but cx tires are scary on tarmac. Luckily only the Sti is broken and should be exchanged soon.

sublorange says:

there is an instagram account named @bicyclepubes that makes fun of current trends in "alternative cycling", initially as drawings made in MS Paint and now as fully built monstrosities. genuinely though, congratulations on realizing your vision on such a unique bike!
