Pinnacle Arkose 3 2018 Sizing

Hello,

after the recommendation of Evan Cycles I ordered a Pinnacle Arkose Bike in size L. I am 183cm tall and my inseam length is around 85cm. I am not sure if I have decided correctly after I read the reviews on road.cc. The riders between 180-183 all testet the bike in size M!? 

Could anyone help me? Maybe someone riding a Pinnacle Arkose bike with similar body size?

Thanks in advance!
