Bianchi Sprint Fit

Hi all,

I’m new to cycling (30M), I’ve been sporting all my life, and took up indoor rowing throughout COVID. I’m kind of over it now and want to get out into the real world so decided to take up road cycling.

Just purchased a bianchi sprint 2024 105 12s. There was a great deal on a size 59 and I went for it (after careful research). At one point I found a fitting guide which I can no longer find stating that an inseam of 87cm would correspond to a size 59. I measured my inseam at 86cm (if I really shove the book up there it’s 87-88cm).

Im 183cm tall, and lately I’ve been reading from other users that at that height they are riding mostly 56s/sometimes 58s/rarely 59s.

Does anyone with my approximate dimensions have experience with this bike? Is it indeed too big or will it be ok?? Thanks!!
