Someone posted this earlier today on the facebook group - 

Blue lug blogged about a 20" gravel king tyre from panaracer here.
Seems to be on sale already in two colours - here and here. Limited to 2.1", so I guess restricted to the Llama's, the All-packa, and maybe the disc-NWT.

This is great. I find that 2.1 is the max my nwt will fit without being too close for comfort with the rear mech and the tire.

Nwt with rim/disc? What year? :)

Here is the Panaracer spec-page for the 406mm X1 tire.

When I saw the title, I was hoping they had created a 406mm version of the Gravelking 'Slick'. But they've created a blocky-knoby. It appears to be shaped to a round profile (which is nice), but there's still a lot of rubber. It comes in 100g more than the 60tpi 2.1-inch version of the Tioga PowerBlock. I'm really curious to see how it behaves. But I already have so many 406mm tires on the wall, that I can't really see buying a set right now.

On the up side, it does claim to be tubeless compatible. As far as I know, there hasn't been a tubeless 406mm tire since Schwalbe discontinued their HS-434 'Shredda'.

The "competition" here would be the Schwalbe G-One Allround, which is also a tubeless compatible 2.1" with a bit of small knobs. It's pretty impressive and I'm sure the Gravel King X1 will be similar.

Sorry to hijack this thread, but I’m going to anyway ... this is still about tires!

If you are looking for a wider 451 tire, I can recommend the Tioga Fastr-X.  Really nice ride, but they were also very hard to find in the more-supple Kevlar bead version.  They are nominally 20 x 1⅜” and come in a bit wider than the Primo Comet 1⅜” width on the same rims. (The photos show them on Velocity A23 rims; Tioga says to use a rim with 16mm internal width or more.)

I’m selling a single mounted-but-not-ridden wire-bead edition, and a pair of lightly-ridden tires (maybe 300 miles?) in the folding edition.  I was running them on my Air Friday, with fenders (aka mudguards).  

So, why am I selling them?  I’ve decided that the clearances are a bit too close for comfort.  Make your own decision here.  With Disk brakes, or V-brakes I think that they would be just fine; the narrowest clearance on my bike was under the brake caliper.

Please contact me on blacksha...@gmail.com if you are interested.  I’ll sell them for $20 each, plus shipping to wherever you are.

But  I don't see that Schwalbe makes the G-One Allround in a 406mm size :(

We’ve got them for sale at the shop for $66 each. 

It’s also Brompton’s stock tire on the G-Line:
They’ve always been hard to find on Schwalbe’s website. A customer first pointed them out to me and I looked and couldn’t find them. Then he sent a direct link. 

Unfortunately, that doesn’t work anymore. Given Brompton’s singular usage of that tire, I doubt it’s going away. Probably just in the middle of updating for the new year.

$66 from BF is a great price for the Schwalbe G-One All Around 20"x2.1". They can also be ordered from REI at $82.50  (free shipping) with 10% back in rewards for REI members.


They are difficult to find using the name on the side wall. REI has them listed as "G One Tire for G Line."  But if you search for Schwalbe G Line and Brompton, you start to get lots of hits.

They are 54-406, foldable, and tubless compatible.

How does this Schwalbe G-One compare to the Schwalbe Billy Bonkers? The tread looks similar. Walter, do you have any insights on this?  I have the Billy Bonkers on my All-Day and find them to be a very comfortable supple tire. I have thought about getting some for my NWT, but perhaps I should look at the G-One tires instead?

I'm sure they'd work out well on tandem Tuesday.  Our Schwalbe Big Apple 2.0 tires are great on pavement and flat surfaces, but we have had some sideways sliding on gravel, crowned roads on a few bike tours of Europe.  The Panaracers look like a tire to consider in the future as replacements for off road riding.

The Allround is similar but wider, more supple, and tubeless compatible. I’d recommend it as a better alternative to the Billy Bonkers. 

I wonder if the Gravel Kings aren’t even one step above those.
