I have fitted the front wheel with its 74mm OLN Pantour hub and it looks like I have a 2004 model. The braking surface on the Rolf Accel is 10mm, and the stated minimum requirement according to Dahon is 12mm. Unperturbed, I ignored Dahon's recommendation (they advise hole 1 for the trajectory screw) and went for hole 4 after reading various helpful posts on the Dahon forum. However, after giving the bike I quick spin, and with the brake blocks at the top of the rim, they are still eating into the aero portion of the rim by a couple of mm or so under load. Damn!
I have just ordered narrower brake blocks and am looking into getting stiffer elastomers. As it is, I think I will have to go with hole 1 or 2 (which provides less vertical movement) as I cannot afford front brake failure on a fixed.
