After 9 months of riding with a 10 cm stem (decreased from the stock 11), I want to increase the comfort. It looks that my available time for training will reduce, thus, I can not face the stretched ("race") position anymore (although in the near past I was able to make 2 rides of 150 km with that configuration).

I was wondering whether a further reduction of 2 cm (stem lenght going down from 10 to 8 cm) will make a 59 size bike to look strange, or is it still acceptable?
