I picked up a nice vintage Nishiki for four bucks at a garage sale. Problem: it has solid inner tubes. My biker friend told me I had to hacksaw them off and replace with regular tubes and tires. Well, 'tain't so easy! I have hacksawed through them down to the rim in four places, pulled them with vice-grips and pried them with screwdrivers, and they are still good as new! I think they are still quite ridable, even after being completely sawn in quarters.
Are they glued in place?
Any tips for removing them?
Thanks for any suggestions you can offer!
