    Any old-school (2006) fitters here?



    On my 2006 CAAD8 R800 39/52 bicycle, I've decided to use these fit guidelines as a starting point. I'm going with all of the lesser numbers on that chart, the left-side column. They have proven to be quite accurate so far.

    Handlebar: 2006 Cannondale Fire, 31.8 mm, 42 cm, (15cm drop)
    Dual-Control Levers: 2006 Shimano STI 105

    The handlebars are anatomic with the ramps are angled downwards. As a starting point, I looked at how Cannondale had them configured in their marketing photos. These are all supposedly 2006 CAAD8 frames with the same Cannondale Fire 31.8mm handlebars but with different dual-control levers, depending on the price point:



    And here are two photos of professional racer's bicycles with anatomic drop bars, I believe at least the first photo is from 2006:



    This is from 1997:



    My concern is with the relatively steep ramp angle on the Cannondale Fires. Because of the downward angle of the ramps, the bar-shifter transition will not be perfectly horizontal. I need information on the correct configuration for this type of equipment. Specifically, the correct horizontal angle for the dual-control levers. As for the handlebars, all of the photos appear to have the bar ends pointed at the rear brakes or just slightly below so that's what I'll be doing.

    Ignore the photos. They look nice and that's all they do. They don't illustrate anything. I don't use any numbers. I fit the bike to the person by eye.

    #1 , do the heel-on-pedal-with-locked knee thing to get saddle height.
    #2 , decide on your saddle to bar drop and set that. There's no right drop. Some like the stem slammed, others level with the saddle.
    #3 , get your saddle fore-and-aft position dialed. Watch this video. Make your position like hers:
    Pedaling Efficiency.wmv - YouTube
    Recheck your saddle height.
    #4 , get your stretch dialed. I like to have about 2" between my elbow and forward knee when my forearms are about horizontal on hoods or deep in the drops. Some people like more.
    #5 , get your bar tops dialed. In your low fast cruise position, your wrists should lay flat on the bar top ramps leading to the hoods with your forearms more or less horizontal. Ignore what the drops point to. Who cares?
    #6 , bring your hoods to where they're comfortable to hold with your wrists lying on the bar tops.
    #7 , check braking from the drops. You'll have to mess with 5, 6, and 7 until it all works and you can brake comfortably from the drops.
    #8 , Tape!

    Some bars are built to have nice flat ramps, others don't. I prefer those that do. Your fit should look like the woman's in the video when you're done.

    What about the angle of the hooks?

    As long as my hands are comfortable when I'm tucked in the drops, I don't care. And there's really no reason to ride the drops unless one is trying to get aero. Anything less than being deep and one is more aero on the hoods. IMO.

    Don't you mean "hooks" or do you actually hold on to the drops? And the angle of the handlebar affects both since they are both names for sections of the handlebar. The angle certainly has an effect on comfort among other things. I'm not sure what you mean by "being deep".

    I was using that term to indicate hands either in the hooks or the ergo section, depending on the bar type. Hands forward, not straight down like one sees too many people.

    What I've been trying to say is the ramps on these handlebars have a very downward slope to them, and setting them to be horizontal would make the angle of the hooks and the drops very steep.

    The ramps don't have to be absolutely horizontal (mine aren't), but they should be at the same angle as your wrists when in your low cruise position. Something like the 'dale photo with the Fulcrum wheels can work well. Those ramps are a bit more horizontal then they appear in that photo. You might have to go to a slightly different bar shape, but I doubt it.

    You just have to do the fit and see how it goes.
