    Fit questions - with video

    Hey-

    Seems to me my hips are rocking, unless I just have terrible form? What do you all think? Anything jump out as good, bad, etc?

    Thanks.

    It looks good to me, the only thing I'd mention is that I think the leg should be straighter at full extension (move the saddle up a bit).

    Looks good to me, too; hard to see if hips are rocking without seeing from behind, but Given your leg extension, I wouldn't expect it.

    Looks like a good, sporting classic fit, and unless you're having specific problems, I wouldn't change anything.

    From this angle is looks like your toe is slightly pointing down when your leg is fully extended and your foot is not quite parallel. It does look like you have some hip rocking, but would be easier to see with the camera angle from behind. Not saying this doesn't work for you, but looks like the seat height could come down a few cm's.

    I'm by no means an expert but it looks pretty good to me but looks like the seat could come down a little. A bit of rocking and your legs seem to be a bit stretched.

    Last time I was fitted for a bike, they had me put my heel on the pedal when at the bottom of the pedal stroke and adjusted the seat til my leg was straight and I haven't had to touch the seat since.

    Thanks, so I'll try lowering the saddle a bit for tomorrow morning's ride and see how that goes. I'll hopefully remember to keep my foot straighter too.

    I don't see anything that would warrant a lower saddle height. It is perfectly normal to have the toes pointing down at the bottom of the stroke; it would be unusual if your foot was flat actually. There is some rocking, but that could be a combination of not having the best form in the world and being on a rigid trainer instead of having the bike move freely under you. You don't seem to be reaching in any case. As far as I can tell, your knee angle is close to 35 degrees or even slightly more at full extension, again pointing to the saddle not being too high.

    Do you get any hamstring or achilles soreness or pain on long rides? That would be a good indicator of having the saddle too high.

    Honestly it looks pretty good. Obviously "fit" is subjective and can be tweaked for your specific needs and riding style.

    More important, how does it FEEL? Any significant discomfort issues during or after a ride??

    You can get a goniometer delivered to your door for $15, and put all the seat height speculation to rest.

    Some riders naturally pedal toes down, while others have the foot in a more level position. Setting the saddle high enough so that your heel can just touch the pedal with your leg fully extended is a good suggestion to start with.

    Looks good. Your back could be straighter. Try rotating your pelvis more forward. Not everyone is comfortable that way though, perhaps most notably Lance.

    It appears as if your seat is far back. If you used KOPS as a starting point, your knee in the video appears to be way behind the pedal axle. Does the back of your knee hurt after a long ride? If all feels comfy and you feel balanced on the bike, stick with it.

    As the other guys said, pretty good. Your pedal stroke doesn't look real natural to me...but it may have been just the video. You may want to experiment a bit with saddle setback and seat height. Maybe a touch high and touch too far back as mentioned. Close tho and better than most.

    Here are my current settings:

    Inseam is 35" and I'm 6'.

    Frame is 58
    TT is 57.5
    Stem is 110mm

    Saddle height at 79cm
    Setback is 10cm
    Drop is 10cm

    I have a bad lower back, and have been thinking about flipping my stem up and reducing the drop, which would probably allow me to straighten my back without bending too low. More of a French fit.
    I feel balanced with my current setback - but notice more hamstring tightness lately (my hamstrings are tight as it is). I like more setback though but I'll experiment!

    I'm always tweaking my fit, so ill try the heels on the pedal trick and see where that puts the saddle height.
