I have mentioned the 580 frame feels a little large for me as I’m just 183cm. Yesterday I received a new 90mm carbon stem I ordered from Ebay. The new one felt little heavier than the original 100mm HongFu stem, but it wasn’t expensive (22£ shipped) so I can’t really complain. At least initially the much more compact riding position felt comfier on the saddle. I hope the new stem will help with my aching shoulders. I will need to get some some time on the saddle to really decide whether the change is for the better or still too little and I need to get a smaller frame. This far I have done 360km so I’m about third of the way for my cycling goal of 1000km this season. To be honest riding the chinarello has been so much fun already that I’m already kind of tempted to up the target to 1500km.
