  • Ha, I'm obviously going to listen to him. I have got one yes ;-) I wouldn't really want to set it up myself though and it's ugly as sin. I'd rather let him get it perfect. Anyway, roll on November the 5th! I am excite.

  • This is likely a question for hippy, dammit and James...

    When I go to Scherrit, if he tells me I need a component that he has for fit purposes, does he charge RRP for them, or are they priced competitively?

    He's not going to push his own parts on you. I'm sure he can work to your budget. He may loan you a part or test fit something during the fitting though. He's very accommodating.

  • Interesting isn't it? Good use of technology.

    I might give it a bash at some point over the weekend.

  • Yeah, seems to have come out of nowhere. Guess one of the guys at Double Dog Studios is a cyclist? It'd be interesting to see what it says about my angles (ooh nurse) in midfoot guise.

    It depends really on the item. If you are worried about this, give us a call and Corinne can tell you what we charge for stuff.

    Basically we want to get your fit sorted, and making profit on the parts is somewhat secondary.

    1. Cleat fitting - incorrect cleat fitting accounts for most knee issues we see.

    Current models seem to indicate that its unclear just where the cleat is best. A number of studies which moved the foot forward--- axel towards the middle of foot--- seem to indicate that the assertion is incorrect.

    1. Adjustment - when we get you on the bike we will start to look at optimum measurements for saddle height, reach to the handlebars

    Never put that word in your mouth: "optimum". Its like having someone tell you about the absolute best tasting whiskey. There is NO such thing, for example, as optimum saddle height no more than one could speak about optimum sleep, eating or training. There are models and models are belief based and hardly static. Is the Guimard model of saddle height optimimum or does it reflect a popular training model? Is the empirical observations of what saddle height a winning elite cyclist uses evidence of "optimal" saddle height or of the popularity of a model? Sean Kelly, for example, ran a low saddle? Did he have more knee problems than Bernard Hinault? Current empirical research seems to indicate that positions that provided better Vo2 and power and those that seem to reduce injury don't intersect.

    1. Pedalling technique – the Retul 3D analysis allows us to assess how your knees move during your pedalling action

    And what does that tell you? Look at the stride of runners at the elite level.. Look at marathon runners and one quickly understands that its as individual as one own genetic makeup. Variability is the norm and not "what looks good" (other than the observation that winners always look good).

  • Variability is the norm and not "what looks good" (other than the observation that winners always look good).

    Hmm.

    From the man himself! No, it's fine. I just wanted to see what the situation was. Looking forward to my appointment though :-)

  • Thanks. That could get very expensive, very quickly. Can't exactly tell him I don't want something he is recommending though, ha.

    If you can't afford it, you can't afford it. There nothing wrong with riding a sub-optimal set-up until you can pay for it.

  • Or even after you can.

  • Steve Hogg has some useful information on bike fitting.
    A fair amount you can DIY.
    He suggests fitting assessment when muscles are warm, as do Argos.

  • Steve Hogg has some useful information on bike fitting.

    He indeed seems to say some intelligent things.. but still misses the point that the human body adapts. In order to judge the impact of changes one must wait.

  • Was reading that yesterday.

  • Good videos, those^^

  • Thanks to the excellent video suggested to me by Apollo
    in this thread I am proceeding with my bike fit project with a view to eliminate knee pain.

    I would welcome your thoughts on my little video below:

    Bike fit on the cheap - YouTube

    Points for discussion:

    My heel position:
    I would like to get into the habit of fully extending my hamstrings so my intention is to learn to ride with a horizontal foot. Could it be that my tendency to lift the heel when pedalling is making my saddle position too short? If so, raise the seat or continue to work towards 'correct' heel position?

    Frame Geometry:
    I had this frame made for me to be used for commuter riding so specifically asked for the narrowest wheelbase possible, and in my choice of stem and saddle I generally aimed for an upright position - as recommended by the bike boffins on here. I would hate to give up on the frame entirely, so let's discuss what can be done with saddle and stem below.

    Saddle:
    See picture below where I hold a plum line over my knee. If we follow the advice from the bike fit video

    my knee is further ahead than recommended and as such I should move the saddle back. Only, the Brooks saddle doesn't allow for it. I would hate to give it up now that I've finally have begun to break it in. How important is this? Should I change it for a saddle that can be moved further back?

    Stem:
    OK, I've got no issues with buying another stem. But what angle for the fixed gear rider? The bike fit video suggests 90 degrees between arms and torso, but that's for racing bikes.

  • Frame looks a little small for you, but I'd not choose to be in such an upright position.

  • The top of the plumb line (as far as I understand) should be originating from the bony protrusion below the kneecap.

    Also, do you have an inline post or one with layback?

  • as recommended by the bike boffins on here.

    I lol'd.

  • I've said this on another thread. But the 90 degree thing is designed for when the elbows are pointing slightly back. Due to the wrist angle when gripping hoods. On a flat bar the elbows point out to the sides. This makes a massive difference to amount of weight you want on the front end.

    I'm always faffing with this when setting bikes up for road or off-road. But in basic terms. When my bikes hang next to each other on the wall. My off-road bars tend to be in the same sort of area as my road bar tops. So total reach calculated for road bike minus bar reach seems to work for me.
