I rode my trek domane for Rapha HOTN last april. It was a mud fest and a hoot and have ridden it through Epping forest a few times this summer. It’s remarkabke what it can do, but it’s highlighted that I really should be buying a proper bike for the job
CAADX - canti and 105 = good
XLA - disc and same 105 group from above = also good
Not ridden anything else apart from Pompino and a trek hybrid for lolz at HH SummerCX.
If you just want to test yourself: the xla is decent.
