The DD geo is pretty different- 74 ST is 1 degree slacker than the Jamis (73) and the HT length is taller by 15 MM. I'm confused as to whether this will make the ETT to long, even though they are measured within 2 MM (DD 562, Jamis 560). Any help would be appreciated.
    Yes the 56 is the large. A 1 deg steeper ST pitches the effective TT 13.5 mm forward acc to sheepo. So if you don't change your saddle position relative to your cranks you will have a longer reach and stack. My dilemma was similar, but I use a more forward position relative to my road bike so it worked out for me. My bike (medium) is post #9.

    Sizing help needed on bad EBay purchase

    Hi,

    I am 5'10 with a 31" inseam. I bought (what I thought) was a 56cm disco on EBay. Turns out it is a 54cm. I am worried it is too small. I ride an All-city Nature Boy (55cm...the geometry is slightly larger than a Disco 56cm frame) which is perfect for me, but they tend to run big. Should I stick with the 54cm or wait until the 56cm is available (On-one USA is sold out for another two months). ?????

    Thanks!

    I'm 5'9' w a 32" inseam. I ride a 54 and it fits me well. I like a long stem tho - 12 or 13cm.

    Thanks. I have also looked at the 58cm DD...it has an effective top tube only 10mm longer than my nature boy. The head tube, however, is 30mm longer (although they have different types of headsets). I am wondering if the 58 would work for me?

    I think a 58 is a stretch. I would go towards the smaller frame and fine tune it with your stem length.

    Is it possible to run full hydros on these frames? Or, do the guides not allow it?

    The guides will allow it. I had hydros on mine for a month or so.
