Have been looking at the 54cm Graro frameset to replace my 58cm Felt Broam to go from a relaxed gravel bike to a race gravel bike. About to place my order, but with similar concerns to others here (sizing and the seatpost setback) figured I may as well see if someone with the bike has any input.
Sizing
The 54cm Graro is pretty similar to my 54cm Cannondale CAAD10, but with a higher stack and slightly longer. Love my CAAD10 fit but would say it's slightly too small. Looking at the BikeInsights comparison, the 54cm Graro seems to be slightly higher with a little extra length.
The 56cm Graro is pretty similar to my 58cm Felt but with less stack, and what appears to be a more pushed back seat. I'd say my Felt is too big for me. My Felt has the seat pushed forward pretty far, and seeing the 56 cm Graro has a slacker ST angle and the 15mm seatpost set back, I'm not sure this is the right size for me.
So I think the 54cm Graro is the way to go.
However, just a tad hesitant since Graro would recommend me (72" or 183cm) to go with a 58cm bike. These height charts tend to be crap, but I'm pausing because I'd be going down two sizes and not just one.
Set Up Plans
I'm buying just the frame and will test different stem lengths when I get it. Will then buy a third-party stem and handlebar to internally route the cables.
I plan to move all other parts from my current gravel bike to this one, which includes a 1x setup with a 46t chainring. I've seen people here talking about 46t being too big, wondering if anyone has had success with spacers or if they had to downsize.
I did get the 46t when I lived in Texas (very flat), but now in Arizona and there's more climbing so moving down to 42t might just be smart.
Any and all thoughts are appreciated.
