Thanks!

I'm planning a Gorilla Monsoon bulid, and although that bike is not going to be about going fast i'm looking for some 2.2 tyres that are not too draggy if I ever find myself on pavement for some reason. The Thunder Burt sounds like a perfect candidate with some light MTB wheels.

I'll add a +1 for the thunderburts. I'm running them on my newly converted rigid 29er and they are smoking fast. I can hold nearly the same pace on flat pavement as I can with my '16 Diverge with 35mm G-ones, and the off road performance is vastly superior.

I'm curious what widths you guys are getting after a week or two inflated?

My Thunder Burt Front and Smooth rear seemed to work pretty good in my mixed surface race yesterday. I came in 5th and Im not sure they were noticeably "slower" than the guys on 700c and cross tires. I ran them at 22.5psi front and 23 rear. We have quite a bit of loose gravel around here and the larger tires are amazing to have when there is no good line.

2.1" TB upfront with Hutchinson Black Mamba 127 tpi RR at the back is very fast onroad and pretty deft at (easyish) offroad. Or Maxxis Maxxlite at the back if you like to live dangerously. There are many more fast mtb tire options though.

Sweet! The TB sounds perfect.

My plan is to do 3-4 hour rides mainly on dirt roads with some pavement to connect them, nothing crazy.

I try to do this on my current bike, I have 43 and 38 GravelKing SKs. More than enough grip for what I do and they roll beautifully on pavement, but after about 2 hours I get too beat up. Need some more suspension.

That is good feedback, thanks guys.
The Thunder Burt (TB) has a rolling resistance of about 22.3 watts
For comparison, Conti Gatorskin has 19.3 watts per tire (i.e. not a difference I can feel)
I would guess that the G-One is in the range of 16-21 watts.

So yeah when loose gravel and stability are more important than weight and aero (i.e. most gravel rides/races), there is a strong case for the bigger TB

I’m thinking of putting a 650b 2.1” TB on the front of my bike and a 700c 40mm G-One on the rear (as that is about what my frame will accept.  They seem to have the same diameter.  That would give me a fast/efficient tire for power transfer in the rear, and a wide footprint for gravel stability in the front.

Just as a follow up, I did a race this past weekend with the Thunder Burts. It rained overnight before the race, so the course was wet, with standing water in a lot of places, but not deep mud except a couple of spots. The Thunder Burts were great everywhere except of course in the deep mud. There, they slid around almost like a slick. On the wet dirt they had good traction and rolled well. On pavement they were super fast. I caught quite a few people on paved descents and flats. Now if I could just get fitness to match my tire performance;-).

I continue to be impressed with the TB's. So far I've tackled ~60 miles of urban riding when I traveled for work VIA train and bike, a legit 14 mi XC loop with some mild techy sections, and a 44 mi gravel ride this last weekend with a ton of climbing and some very loose sections. The only time I felt a little held back by them were some of the descents on my XC loop, but this could definitely be remedied with a grippier tire up front... I wasn't expecting DH performance out of a lightweight XC/gravel race tire anyway! I think Schwalbe nailed it with this one.

This was all on my rigid 29er I mentioned above.

I have had the Thunder Burts on Halo Vapour rims, 21 mm internal width, for about a month.  The tires measure exactly 2 inches at the carcass.
