Hello all,
Thank you for the wisdom written.
I'd love to go for a second hand, but right now that doesn't seem possible either as people don't seem to be selling much besides a couple of £900+ Cannondales in my area (probably the lockdown). I think I will still go with the Triban as it seems to be really well reviewed, plus has gravel tires, which I'd not thought before to consider but a couple of good rides near me are hardpacked.
By the sounds of things, it seems best to go for the XL and make adjustments, such as potential new wider handle bars and adjusting seat. Would that be correct? My thinking there is that more space allows for more adjustments, and I would have space to shrink down.
Side note - do all bikes' bars raise or lower? I can't seem to find any info on whether the RC100 does. (If needed, best pictures of the bar are here:

Thanks a lot!
