Currently considering an XS Datum frameset for my partner. Not knowing too much about recent tech is there any reason why i'd regret the slightly dated QR/15mm TA over 12mm TA front and rear? Only comparable option we've found that has 12mm is the Synapse carbon and i'd really rather not buy a full bike.
Depends: 12mm: newer, hip road bike standard.
QR & 15mm: loads of cheap parts, 15mm has been a mtb disc standard for almost a decade now and theres loads of good longlasting hubs for that. for QR too, obviously. :) So for a DIY wheelbuild, go for QR and 15mm, gonna be way cheaper!

This'll mainly be used on the road.
