As far as I know the Valkyrie suspension was only a prototype featured in MBA on february 1991. The serial Number as many of Mantis prototypes was one of a kind, on the bottom braket Is stamped Mantishock
Stunning bike in a very immaculate condition. The year should be 1986 or late. The price is a little bit demanding... but this version Is very very rare.
In search of an American Classic seatpost, diameter 26.8 lenght at least 300mm. Titanium would be very appreciated.
I'm also searching a set of quick release also made by American Classic.
I'm from Italy. Thanks for the help. Alessandro
I'm always happy when i see a beautiful Mantis to get back at it's former glory! If I may permit Gianni, a Ringle' seatpost will be as " cacio sui maccheroni"...otherwise a beautiful frame with a nice selection of boutique components!
