How can you tell if a 26in tyre will fit a bike that came with the 700 ones. Other than ask the salesperson as I really dont want to go into the why I want to do this and so on.

Please dont suggest I get a mountain bike, I just dont like the look of them for some reason


TIA

700 are a larger diameter then a 26 so it should fit in the frame. The width of the tire is the only thing that could give you a problem

I'm gonna assume a few things here. I think you mean wheels and not just tires (tyres). Obviously a 26" tire will not fit a 700C wheel, but I don't think that's what you mean. In most cases a 26" wheel/tire combo will "fit" a bike that takes a 700C wheel but then there's the issues of brake compatabilty and clearance (on some tight roadbikes). Bikes with disc brakes can usually swap back and forth as I understand it. Beyond this, we're talking alot more specifics needed for an accurate answer.

Maybe I'm confused then..I do get what you say about a 26inch tire(tyre) not fitting a 700c wheel. I guess my real question or to try and and clarify how could I tell if a hybrid bike would work with a 26in wheel/tire combo.

Say like the Kona Dew or anything similar.

Well as I said, brakes may become the issue. If the Kona Dew (or similar) is equipped with disc brakes then as far as I know a set of 26" wheels (w/disc brakes of course) should work on that bike. A bike of the nature of the Kona Dew should have plenty of side clearance to accept most 26" tires. Without disc brakes equipped, then the brake pads won't line up to the braking surface of the 26" rim. The brake mounts on the frame would then have to be relocated. Probably not something I'd recommend. Bear in mind the frame geometry is designed for a particular wheel size, so you may not like how the bike handles after the swap is made, if it's even possible.

Thanks for the assistance. I think I may have solved my problem:) ::fingers crossed::

Some hybrids are designed for 26 inch wheels. Some are designed for 700c. Look at the catalog.

Well, there is drop out spacing to consider:

Good advice about the handling!
