DT Swiss XM 1501 XM 1501 SPLINE ONE 26

First XM 1501 SPLINE ONE generation as shown on DT Swiss's May 2014 page for the 26 inch wheel: 1535 g per set, tubeless ready aluminium clincher rim, IS 6 bolt rotor mount, DT competition straightpull spokes laced 3-cross with DT Pro Lock aluminium nipples, RWS included, a 15/100 mm thru axle front and 12/142 mm thru axle rears with a Shimano and SRAM 9/10 speed body or a SRAM XD 11 speed body (the HG rear was convertible to XD). End caps sold separately converted it to quick release, thru bolt or 135 mm rear standards (spec.axle_conversions). The page gives no rim width, hub model or US price, and the last year on sale is not documented; 2014 is the first year observed on dtswiss.com, not a documented launch year. Price labels fixed 2026-09-27: split from dt-swiss-xm-1501-spline-one, whose 2017 to 2019 wide rim Center Lock data does not describe this wheel; no US price was shown, so both price fields and price_basis are null.
