    New bike and questions on fit

    Hi all - I just purchased a Kona Dew, and I have some questions on whether I should make any adjustments in terms of fit.


    I'm about 5'10", and the bike is 56cm in size. I was able to stand over it and pull the bike up almost two inches before it started hitting anything 'core', if that makes sense.

    When I test rode it, it felt pretty comfortable. Now, though, I get some pain in my shoulders and back. Nothing crippling, but I notice it, especially after longer rides (> 15 miles).

    Part of it is that I'm sure that my posture sucks. Also, I work with computers all day, and that doesn't help the tightness of my back, neck and shoulders. And I've had back problems for several years.

    The bike shop said that they could swap out the stem for one that's shorter. Does anyone think that this would work? Any other things that I could try?

    I know that, for best results, I should have a professional fitting done. I'm a little short on cash at the moment, so that's really my last resort - especially if they tell me that the bike's too big.

    Thanks,
    Phil

    Go shorter and higher. Or, probably even better, get North Road bars:

    Then investigate doing Alexander Technique or Pilates before you cripple yourself permanently.

    Professional fittings are based on complex methodologies designed are around road racing bikes, forget them. With a hybrid: get the standover height right, position the seat to get the correct pedalling position, and then change the stem/bars as needed.

    You know people who've been crippled permanently from riding Konas?

    Gooseman, you've only got a few choices; raise the bars with a riser stem, and/or fit MTB riser bars with a little sweep-back Try a 90mm Ritchey adjustable stem as far up the steerer tube as will fit. If you've got too much weight on your hands, and they're also going numb, you're stretched out too far. If that doesn't work for you, sell the bike while it's still reasonably new.

    Pilates doesn't conquer the laws of gravity. Neither do riser stems.

    If you don't want to spend the cash, you can do your own fitting, which should help quite a bit. It helped me substantially. It was like buying a completely different bike, the change was so dramatic.

    Here's a link to an article on mountain bike fitting, much of which should directly apply to a flat bar hybrid bike:

    No. But the OP's problem doesn't come from a Kona:

    Part of it is that I'm sure that my posture sucks. Also, I work with computers all day, and that doesn't help the tightness of my back, neck and shoulders. And I've had back problems for several years.
    I certainly do know people who have crippled themselves permanently with a mixture of IT and lack of proper exercise.

    Back to the aptly named snafu

    Pilates doesn't conquer the laws of gravity
    No, but it can restore back flexibility and core muscle strength. The OP's problem isn't that the Kona has an aggressive position but that his problems mean that he can't cope with a normal one.

    Would you like to try thinking before posting?

    Post a picture of you on the bike. Could be that you're too stretched out or the bars may be too low (or both). You are probably at the low end height wise for that frame size but it should work with some minor tweaking.

    Liked the article on mtn bike fitting. I have never seen that one before.

    Why don't you try that yourself? Snafu's brain is working perfectly well. Your perpetually snarky attitude is very tiresome and detracts considerably from your posts which would otherwise be well worth reading. His point is that you draw some very strong conclusions from very little information in this case and I agree with him. There is no reason to believe that gooseman is on the verge of permanently crippling himself based on the information given. Snafu's question was understandable, your answer is uncalled for. Or that is the impression your last sentence leaves in the mind of the reader. The bulk of your answer is fine and explains your concern quite well, but then you ruin it in an attempt to prove, what?

    what is your insteam. i had the same problems. to solve them i tried many things. using a shorter stem, adjusting saddle position and angle. after watching this video i recognised the main problem. saddle height. i adjust saddle height according to this formula:

    saddle height = inseam x 0,883

    and also i made this adjustments in this video. saddle angle, position etc..



    i ride about 44 miles for 3 days. and it seems that fitting related issues solved for me. yes there is a bit pain sometimes in my back, shoulders etc. but it is reasonable. i feel prety comfortable for now.

    Hi all - it's been awhile - sorry for the delay! I couldn't find someone to take pictures - but the LBS where I bought the bike swapped the 90 mm stem for a 95 mm adjustable stem, so even though it's longer, I'm more upright. I did a 40 mile ride last week (I had a '40 by 40' goal - 40 miles by my 40th b-day), and I was sore all over from the ride because that was the longest I'd ever done. But my back and neck weren't hurting nearly as much! So I'll be doing some shorter rides, and seeing how it goes!
