I think its actually the 350 which I did look at and assumed only came in 28 hole becuase thats all I could find, but according to the website they're 24 as well. Cheers
No problem. I should note that after about 2000mi the freehub became pretty draggy. Got new wheels because carbonz so never bothered sorting it out, they're my emergency spare wheels now. My mate had similar hubs and had to buy a new freehub after a similar distance I think...
DT Swiss - Whatever hubs are on the R24 Spline DB would match that, apart from the rear would be 10mm thru axle.
My R24s came with various endcaps for QR, thru axle and proper big axle (12x142?).
