hello.

I just got a Koga Miyata from 1978 with Mavic(champion du monde en route) rims.

The tyres are in bad condition and I want to change them with a new ones. But no idea what kind of tires I need to buy. It is possible to buy them in a normal bike shop?? or the must to be ancient tires??

Any tips that fits this kind of bike??

Thanks a lot.

What size are the tires that are on it now? you'll be able to find it printed along the sides.
That'll help a lot.

They might be early 700 or 27 1/4. It is likely the narrow 27 1/4. For the best quality and lowest price tire of the 27 1/4 variety I recommend the Serfas Seca. They are decent tires.

Championnat du monde is a tubular rim isn't it ?

Do you have these rims ?

Along the side of the tyre is nothing. They are in really bad situation. Is not possible to read nothing more.

And I don't know if they are tubulars(it is my first road bike )

For example I can buy those Serfas Seca in a normal shop like for example chainreaction.com??

Deflate the tire...If you can remove it from the rim and there is no tube then you have sew up tires...The tube is sewn inside the tube. In that case you will need to get sew up tires.

Yellow Jersey tires are the best value 3 for 50 but then you still need glue. I think the Continental Cement is the most easy to work with but it takes 24 hours to fully cure...

Thanks a lot for the info guys!!

The problem is that I can't see the size of my rims... Wich tubular size I must buy??

I think the problem is that you are spelling it with a "y". It's spelled T-I-R-E.
