Tigras were really nice bikes, IMO better than Mondia and Allegro... Much less common too!



Here's a link to my 1965 Tigra Professional:

Have you tried all of the tricks like turning the frame upside down and pouring ammonia into the seat tube through the BB? Some people swear by Kroil or other penetrating oils.

One suggestion, gently spread the ears a little (where the seatpost bolt goes through the seat lug). It probably wont help releasing the stuck seatpost but once you get it a little loose you can get it out easier.

BTW, That's a great tool [MENTION=61707]squirtdad[/MENTION] built....

A few years back I bought a Centurion IRONMAN Tri bike without wheels and seat. I got it dirt cheap to build a wet weather beater. The seatpost was stuck in the seat tube. The previous owner rode it in triathlons after coming out of the ocean plus the seatpost was fluted (stupid idea for this kind of bike) so salt water got into the seat tube!

I cut off the seatpost and carefully cut a slot into the stub using a folding brush cutter and a jab saw . Even after I cut through it I had to crush the seatpost in a vise to collapse it enough to remove it! Two hours work!



Afterwards I honed the inside of the seat tube, applied lots of water resistant grease to the inside and put in another well greased seatpost.
