• Rr421 is the shallower version on the rr521. Both are welded. The r470 is sleeve joined. Its still a decent rim but the kinlin xr22rts is lighter and even better for it bead hook, bead lock....

  • I believe you're referring to the 18mm 460.
    @ObiWomKenobi
    From where I stand (I wasn't aware of 421/470/521 until now), said rims are simply 20mm versions of the 18mm 411/460/511.
    470/521 are the only 20mm symmetric disc road rims DT does.
    For what it's worth, 460/470 is a common rim for OTP Spez, Spez dealer I'm friendly with (gasp) haven't had any trouble with them to report of.
