Hi all! So I'm pretty set on the Trek Domane SL6 but between sizes. Also, I don't really have options for test rides and a fit in my area. I could drive an hour to see more inventory but really don't want to waiste a shops time and then buy local.

About me, 55, 5'11", 33.5" inseam, not great neck and kness can get weird, back on the bike last year after some years off with health issues, got up to 30 miles at 17 mph avg. I will get the fit worked out, have done it many times, but being right in the middle of sizes kinda stinks. Goals this year, improve to max 60 mile rides and 19 mph avg.

Looking at Trek I fall exactly at the top end of a 56 and the bottom end of a 58. One thing I notice is the 56 comes with a 170 crank and the 58 a 172.5 crank, my current bikes are 175 cranks. I'm leaning towrd the 58 cause I figure I can always shorten the stem from 100 to 90 for a bit reduced reach if needed. Thoughts please and thank you!
