    WTB Drop Bar Shifter Adapter Question

    Hi - Can someone with these adapters measure & tell me what dimensions "A" and "B" are?

    I'm making a set and need these dimensions as a starting point.

    "A" is from centerline of handlebar to back of shifter.

    "B" is from centerline of bar mount to center of shifter.

    Thanks!

    I snagged the picture off this site, let me know if it's yours and I will give credit.

    That's great, retrodude! I appreciate peoples' rides and effort. Now, I'll try to get somebody who is better at measuring in here to help ya! You can ask DoubleCentury how awful I am at measurements.

    Measure once, cut twice?

    That's my photo. A = 3 inches, B = 2 inches. The silver spacer is my addition to allow room for larger-than-child's-hands to operate. Without it A = 2.5 inches. Good luck.

    Thanks GOB & DC!

    I'm making mounts for a set of M732 shifters to convert the Ti Fat to drops.

    I'm immensely interested in this project. I'm currently in the process of adapting a Merlin with an LD and WTB Dirt Drop bars. I'm either going to go with some Suntour Command shifters or the M732s with a homemade DKG-style mount or perhaps some homemade WTB mounts. I've pondered how I would make the WTB mounts, and haven't come up with any easy way to do it. Please share how yo are going to do this. Lots of pics too. Thanks.

    I believe the Ti Fat and Yo Eddy are not the best candidates for dirt drops. Top Tubes are long and head tubes are way too short. Even the wicked, w/ it's short top tube is not good due to short head tubes.
    want: Ibis ti handlebar. suntour 31.8 front derr. bottom pull

    Time machine or a lot of patience.
    Seek: Koski Trailmaster. Breezer Series 2, or 3. Fillet brazed Ibis Custom. Cunningham Racer. Otis Guy (but not that softride model). That's all I need I don't need anything else... except... except for an old Mountain Goat bar stem combo. And that's all I need. I don't need anything else. Except.....

    some progress

    Been busy with work, eagle ceremony, high school graduation, college graduation, 25th wedding anniversary, yada yada yada... anyway, this is as far as I've gotten. Modeled up & 3d printed for fit/reach. Need to get this wrapped up, going to run drops for the Blackfly Challenge again. My son confiscated my Unicoi with drops and I don't want to ride/race 40 miles of dirt roads with flats. The plan was to model & print then have friend fab a set from aluminum, looks like I'll be using the printed parts.WTB Drop Bar Shifter Adapter Question-0504132255.jpgWTB Drop Bar Shifter Adapter Question-0504132256.jpgWTB Drop Bar Shifter Adapter Question-0504132256a.jpg

    Wow! 3D printed retro bike parts! Could jet packs and flying cars be far behind?!

    Is the plastic sturdy enough to hold up to riding? Any idea about UV resistance?
    Don't call it a gooseneck.
