It seems pretty clear from the article that front isospeed is out - it isnt included on the new 2022 checkpoints either.
They'd be crazy to eliminate the downtube storage IMO - that has to be popular.
Does anyone know how to get the Domane with that shorter head tube? Is that only for the semi-custom project 1 bikes?
With rear IsoSpeed, there's a pivot point at the top tube/seat tube junction - even on models where an internal post might not be impeded, shoving a seat post through that pivot point would defeat the purpose of tuned flex.
The shorter head tubes are from a different fit option (their fit options are labeled H1 [most aggressive], H1.5. H2 [least aggressive/endurance]) and typically only available on the SLR models.
