    If you want to feel ‘in’ rather than ‘on’ the bike you want a low BB and a long reach. Do you shuffle back on the Parkwood because you find the seat tube too steep or because the bars aren’t far enough away?

    VERY much the feeling I get on this…

    It’s an inconvenient and somewhat expensive way to get exactly what you want, buying a bike then upgrading everything on it, but I knew from the geometry it was the closest to what I wanted (which was the limited edition Whyte 929 from a few years ago in truth) so went for it… The Whyte geo chart is a little conservative too to be fair, as with a 120mm fork on I’ve measured my medium sized bike at 67HA, 1160mm wheelbase, 308mm BB height (with 2.25″ tyres) and the reach/stack/TT lengths are all perfect for me running a 55mm stem and a low rise bar (I’m 5ft10 FWIW). It corners like its on rails, and at under 26lb inc Reverb and pedals its no slouch when you stamp on the gas!

    I’ve got a lay back post already and still keep shuffling rearward on it.

    I got a 25mm layback post, it makes all the difference

    I also have a L Parkwood and in comparison with my XL Smuggler it is pretty short, but I quite like that for what I use it for, it turns really nicely for a wagon wheeler. If I was doing xc races I’d want something longer.

    Mboy are you saying that you shuffle back all the time on the whyte or do you fit in it ??

    What size is it BTW. I think I would be after a large ? EDIT doh just read its a medium.

    Trek Superfly is pretty good geo on the trail, but only 100mm forks. Nice long ett, plenty of standover and takes 2 bottles (essential for long tides for me).

    Fit in it nicely. It’s got a nice low BB, long front centre, slack HA, very much feel in the bike not on it.

    IMO On One missed a trick with that Parkwood, cos the price is right, the weight is bang on, but the geometry is somewhat behind the times… Seat angle is too slack, head angle not slack enough, reach figures are at least 25mm too short size for size, and the head tubes could be shorter. Oh and the BB whilst not lofty could be lower.

    The 650b parkwood geometry is worse, about 20m less real than the 29r

    *less reach* even.

    Don’t understand it to be honest. On one are normally pretty good geometry wise but this seems a bit strange.

    Not the cheapest way to do it but I had Nicolai make me an Argon custom. 470mm reach with a shorter back end. Mine is an XC race bike but they will tailor their bikes however you want for a cost.

    Things change, OO didn’t that’s why.

    Hmmm, not convinced about that, latest On One email introducing the DeeDar as “long low and slack”, err sorry but that’s not long by any stretch of the imagination (or even reasonably long)

    ^ Surely the ‘DeeDar’ geo is wrong? Surely?!? 😯

    Nukeproof Scout? It’s built for 130mm (if there’s such a thing as a EC56 headset, that’d deal with that) and you’d probably want to go up a size as it’s short of reach… But it’s good. Even with a shorter fork it’ll still be slacker than a lot of the competition. It’s also stiff as ****, I couldn’t live with that personally but I liked it otherwise.

    Had a similar issue with my fireline – great bike but way shorter than advertised so reach is way down. So that is for sale! Ended up going for the Cotic Solaris mk2 in XL to get the reach I like. Building up now but looks great in gunmetal grey! I tried the Scout and it is fun but you would not want to ride it all day – it really is stiff.

    Crashrash, what size is your Fireline and how does it differ to O-O’s shonky geo charts? And obviously, how much are you after?
