Final Review: DT Swiss Spline 1 XM 1501 Wheels- by Grannygear
It seems a bit redundant to post about the Dt Swiss Spline 1 XM 1501 wheels since I did the Mid Term here (and the OOB here) because since I wrote the Mid Term, which was written after a thorough wringing out on the trails of Flagstaff, AZ, nothing much has happened. The XM 1501s just keep doing their job. They, along with the Specialized Ground Control and Butcher tires, have held air just fine. No burps, etc. They are as true as ever and I have not had to touch a thing….spokes, hub adjustment, etc. Nada.
I have ridden them a bit easier on the smoother trails at home, but they have also done some pretty long XC type rides and I have yet to feel they held me back speed or acceleration wise, the bigger tires not withstanding. I did save some weight over the stock Roval wheels that came on the Camber (also a DT Swiss based rear hub) and I did not notice any loss in stiffness with the swap over.
Basically, kind of an anticlimactic finish but that is what you want from a wheel, yes? Well let’s talk price. I am seeing the XM 1501s at around $1,100.00 a set and they weigh in at 1,680g for both wheels. The stock Rovals would be in the 1800g range but sell for MSRP of $700.00. The new SRAM Roam 50 is in this league, is a bit narrower (21mm internal) and weighs in at 1,610g in “the lightest configuration” and look to be selling in that $1,100.00 range too. Easton Haven 29s are a bit heavier at just under 1,800g and sell for just under a grand MSRP. The biggest fly in the ointment might be the Roval Control 29 Carbon that has an MSRP of $1200.00 and weighs less at 1,580g.
So the Dt Swiss Spline 1 XM 1501 wheels look to be in the ballpark price and weight/performance wise. The unique PRS (Pro Head Re-inforcement) washer/nipple system and Squorx Pro Lock nipples, straight pull spoke, easy swap end caps for axle compatibility, RWS ratchet system and the wider rims…well it is nice combo of features and tech. I do not expect any future surprises and I anticipate that buyers of this wheel set will have the same results we have had.
