Enve boss til SRAM XDR
XDR (“R” is for Road) is the road version of the XD freehub body.
It looks similar in appearance to the XD freehub body, but is machined 1.85mm deeper where the cassette threads onto the freehub. This is in an effort to match the flange spacing for road hubs, so a re-dish is not required.
Similar to the XD design, XDR allows for less than a 11-tooth cog, for a wider gear range on the cassette. While XDR is road specific, a 1.85mm spacer (Supplied by SRAM) can be used on the XDR freehub body to accommodate XD cassettes.
XDR driver bodies will fit 11 and 12 speed drivetrains with XDR specific cassettes. The XDR freehub option is available on our G Series line, and our SES Road Disc line of wheels.
