• How is yours proportioned?

    56cm seat tube, 58.5cm top tube.

    Regarding the R559: did you had to file them down or even open the tabs?

    Not sure what you mean. I did have to drill a hole in the mono stay, as the mudguard hole at the back isn't through and through. And I changed the caliper bolt to a longer one, so I could put a nut onto it (since you can't recess the hole for a recessed nut, as the seat tube is in the way to be able to drill it).

    what is the maximum tire width with your current setup?

    I recon 650b x 47c will fit. Haven't tried it (yet) though. Currently running 42c with 51mm guards.

    measured a 26.2 diameter seatpost. Correct?

    I've got a 26.4mm in there.

    Good luck with the Muddy Fox; those plans sound good! Would be cool to see some pictures.

  • Thanks @Tijs for the information!

    Strange...this would be quite different to our geometry. Length almost the same, but the seat tube is so different...guess you measured centre-to-centre with the seat tube? Measuring centre-to-end of the seat post gives me 55cm.

    Hole in the monostay sounds like a good idea we should give the frame when its naked.

    With the filing of the tabs I meant if you were able to move the brake pad the required amount down to the rim, without modifying the brakes itself...if the brake arms are not long enough, one could file the hole where the pads are mounted at the bottom, to get even lower with the pads. Would be nice, if it would work without modifying the brakes....

    Good to hear that 42mm fits fine and 47mm could also eventually be possible...and: will keep you updated on the build of course!

  • guess you measured centre-to-centre with the seat tube?

    Yes, both c-c.

    With the filing of the tabs I meant if you were able to move the brake pad the required amount down to the rim, without modifying the brakes itself.

    I my case the front still has some room left to lower the pads, and the rear ones are all the way down in the tabs. Ideally I would want a little bit more adjustment for the rear, so might file them in the future. Bear in mind the tolerances of positioning the studs when the frame was made, so your miles may vary.
