700C x 29 mm Extra Léger Tires


We asked Grand Bois for Extra Léger tires in other sizes than those already available. As a result, we now have a limited quantity of 700C x 29 mm (28 mm nominal width) Grand Bois Extra-Léger tires available. They are not on the Compass web site yet, but you can order them here.

This means that the Grand Bois Extra Léger tires are available in the following sizes:

  • 700C x 23 mm
  • 700C x 29 mm
  • 700C x 32 mm
  • 650B x 42 mm

    Great news for those who can’t fit the 32s. I’m on a pair, and they are FAST!

    Hi there, I LOVE the 42mm EL tires on my 650B converted Trek commuter. I am thinking your 29mm might just fit on my ’95 Bianchi Eros, the campy mirage brakes are the chokepoint I’m afraid. Do you have a vertical measurement for a fully inflated tire, edge of rim to the furthest extent of the tire?

  3. René Sterental says:

    Is there any chance we’ll also get a 700×40 or similar Extra Leger tire added to the group?

  4. Greg says:

    Woo hoo! Most excellent news.
    Now that these are available, we just need some 700 x 26 ELs with tan sidewalls as well. Keep ’em coming!

    Super exciting. Thanks for that. I feel kind of spoiled at how many terrific tires there are available now.

    If wishes were horses (or bicycle tires), one of these days there’d be an Extra Leger variant of the excellent Compass 26″ x 1.75″… I’m loving the 700c x 32mm variant.

    How do they compare to the Challenge Parigi Roubax tires? It is an expensive experiment just to find out if any difference can be felt.

    • In my experience, the Challenge Parigi-Roubaix tires have a ride that is comparable to the standard Grand Bois tires. Our tire testing confirms that the two tires offer comparable performance. However, the Challenge tires wear much faster than the Grand Bois, so per mile, they are much more expensive.

      The Extra Leger Grand Bois tires are definitely more supple than the Challenge – it’s a very noticeable difference.

        The Extra Leger Grand Bois “Cerf” 700C x 29mm tires arrived yesterday. I mounted them this morning and repeated the same ride I did the day before on the Challenge Parigi-Roubaix tires. Yes, the Extra Leger make an incremental, but definitely noticeable, difference in feel. Riding over alligator one and two road conditions is smoother (see: http://en.wikipedia.org/wiki/Crocodile_cracking Los Angeles rates alligator cracking from 1 to 3, from mild to chunks missing.), and they do not transmit as much buzz from the road surface.

        Thank you for importing these tires.

    Just curious – How would these compare to the only other high-end 700x28ish tire I know of, the Challenge Parigi-Roubaix?

    I vote for 650b x 38mm (for bikes from the pre-Hetre era) 🙂
