Price labels fixed 2026-09-27: split the 2014 26 inch IS 6 bolt generation into dt-swiss-xm-1501-spline-one-2014 (years here now start 2017, the first observed year of this wide rim Center Lock generation, and the May 2014 source moved to the new entry), added xd to compat.freehub because the 2019 Boost HG rears ship with a SRAM XD freehub body kit, and left list_price_usd $1165 (2019-12, per set, price_basis pair) unchanged.
