Trek emonda carbon with discs and thru axles.

All fine apart from chainstays , is this 2-3 mm gap between chainstays ok?

    you will get grit, stones dirt or whatever in there and it will rub in no time.

    there is an article here on Cervélo tyre clearances
    the interesting bit is there is actually an ISO required minimum allowable clearance for safety. The difference between these two dimensions is 4mm (per side).
    fwiw, my Cervélo C3 can take 32mm tyres ok, but 36/38 mm tyres 'just' rub, so this confirms the Cervélo clearances are pretty much spot on
