Internet bike fit/gravel riding question.
I normally ride a 54 CAAD road frame with not much seatpost and very little standover clearance as the stack works for me. I've been thinking of making a switch to something more durable/comfortable and by chance my girlfriend has offered me her XS Datum as she isn't using it. Geo charts tell me stack is essentially the same but the reach is 18mm less on the Datum. Before i get excited and start trying to make it fit me i thought i'd ask the hive mind if it's a road(trail) to nowhere.
Looking at most the bikes posted here it seems like longer top tubes and shorter stems is the norm. The wheelbase on the Datum is still 10mm bigger then the CAAD but would i be at any significant disadvantage with a shorter top tube other than i'll need a longer stem which isn't ideal for getting rad? FWIW i'd be using 165mm cranks. Standover difference is 30mm but i would have thought that would be a good thing if i want to do sick jumps over bumpy stuff.
