    Your current tubes have tread-knobs on them to fit into the knobs on your off-road tires. You'll need to buy smooth-sided tubes.

    Fixed.

    You're current tubes should be fine unless you dramatically change the width of the tire.

    My lbs is always out of those. Can you give me a link to where I can get those ?

    Actually the reason I asked this was I spoke with 2 different sales people at my lbs and they gave me both opposite explanations.

    Most tubes had the size on the side of the box. Mine say 26X1.90-2.125...If I used slicks that were 1.50, I'd use the appropriate tubes.

    Use the correct size to avoid any confusion. I know riders that don't, I just like it to be right.
