Having studied bike geometry for a long time, I look at the trail number and maybe the front-center if toe overlap is your concern. The 67mm trail is not overly large for the intended use of this frame. Some Italian brands don't even list the HTA or fork offset, considering their preferred dimensions a secret. I owned a 55cm Tommasini Sintesi back in the 90's that was that way. I still have a catalog of their offerings from that time. Colnago did the same. My current Cinelli Superstar has a 71 degree HTA with a 45mm fork offset that yields a trail of about 70mm, depending on the tire size. It handles great. My new Yoeleo frames have a 71.5 degree HTA and 43mm offset, that yields about 3mm less trail.
I use the formula (R/tanH) - (offset/sinH) for trail. The first half of the equation is the trail without fork offset and the second half is the reduction in trail from the offset. The larger the tire diameter, the larger the trail. I've never seen a brand that listed a tire size.
