    08/09 R3-SL geometry

    Hi all, Has the geo changed from the older 08/09 R3-SL to the newer 12/13 R3, looking at the headtube length. A link to the older geo or info would be great.

    cheers

    R series 'old' is the same as the current S2

    Thanks for that, just to clear it up my 08 R3-SL in 61cm has a head tube of 199mm, same as my 2012 S2, and the newer R3's have a headtube of 225mm in 61cm.

    cheers

    The S2 (=R series 'old) geo table i am looking at says 200 mm head tube lenght, where the current R series has 225 (both size 61)

    you'd be better off comparing stack heights

    Size 61:              Size 61:

    S2 R old = 599   R series new = 630   makes + 31      (reach = 409  vs 405)   makes  - 4

    if you feel that the front is getting too high, you may consider going down one size;

    Size 61               Size 58

    S2 R old = 599  R serie new = 605     makes  + 6       (reach = 409 vs 396)    makes - 13

    so, assuming you want to replicate you position on a new R, and you are not using the longest possible stem and the lowest headset to stem configuration, the 58 is the way to go

    Thanks all for the replies. Has anyone gone from the old geo R3 to the new geo R3/5 and noticed any difference in the ride/handling?

    cheers

    yes, i think the R3 new is more vertically compliant at the front, most likely because of the fork specifically designed for this bike (and not the generic 3T which). handling still a good mix of quick with good straight line stability

    Good to know, I might hold out for a 13 model R5 with Red next year.

    My experience was slightly the opposite. My main gripe about the old (pre-201 R-series) was how the front end of bike was too compliant...mostly lateral flex, especially noticeable on high speed downhills or tight cornering. The front end softness was addressed with the larger tapered headtube and oversized crown race and bearing, on 2011 and newer R-Series frames. The new front end is stiffer and provides a much more balanced and stable frame, with more neutral and predictable handling.EM3
