    1988-89 Mantis Valkyrie

    So I posted this in the "all things Mantis" thread but i figured that I would start my rebuild thread.

    This was listed locally on CL and I was lucky enough to be the first to call the owner, Rick. Not only did he have the Mantis listed but also a R and E Terra Tech that had some tasty parts.
    When I went to pick both bikes up Rick told me he had many offers for up to 4 times his asking price. But Rick being the guy he is, held true to his original price and here it sits.
    Not only did I get the Mantis with original fork but also a box of random parts that included to my delight the original Mantis stem.
    I also got a set of Red/Black Bullseye hubs laced to Mavic MA 2 rims(are the MA2 the Bontrager rims?), Topline cranks, Kooka Cranks, Grafton pedals and other bits. Rick also through in 2 mantis T-shirts with one being signed by RC.

    I have always wanted a Mantis as they remind me of the old Quadangle that I lusted after as a kid. Also, Seeing DC's lime green Mantis from years ago made me want one even more so...........

    The story behind this Mantis goes something like this:
    Rick, the original owner, had this made custom back in 88 or 89. He can not remember which. He raced and rode it for about 5 years before it cracked around the seat tube.(it seems this was common)
    Rick sent it back to Mantis and had it re-welded but they forgot to put the front dererailer and rear brake cable guide and stop on.
    Mantis told him to send it back but by then he had picked up a Amp and never did anything with the Mantis.

    The paint is in rough shape so as soon as I get the guide and stop put back on it will get a repaint. I am thinking Candy Apple Green.

    In the past 3 days I have had many ideas of how to build this up.
    650B conversion?
    Drop bar?
    Full XT M7**?
    I am not quite sure yet.
    The frame is a 18" with a 22" top tube. A little small for my 6-1 frame so that is why it makes this a perfect 650B canidate.
    I will post photos and updates as it happens.
    Thanks,
    LJ

    I have a NOS set of MA2 rims in 26 inch. I figured they were not a Bontrager product because the green/yellow MA2 stickers go right over the rim joint.

    I have another rim that appears to be a Super Champion that is probably a Bontrager cut down, because the joint has excess epoxy around it.

    Not sure how that would like it fit bigger either unless you plan on dropping the BB.

    I think a 650B with drops would be rather cool.

    Now that I know the chrome stem is indead a Mantis I am 99% sure that it will get built with the proper mix of era correct componentry.

    I am meeting with my welder friend on Tuesday so first things first.

    Although maybe not the original paint scheme, I really like how that red fork looks with the dark frame.

    And yes, the drops look nice on there!

    If you are thinking about making that a singlespeed, you may need a tensioned tensioner (i.e. Paul Melvin or a old derailleur). When I made my Nishiki Ariel a singlespeed, the rear end wagged like crazy and would ultimately break chains.

    Cable guide

    Take some shot for the cable guide of front derailleur and rear brake. I hope this could be useful.

    How are you planning to adapt the brakes for 650b?
