New RH Endurance Tires in 700C and 650B

Many of you asked for more tires with Endurance casings… The 700C x 35 has long been a favorite of gravel racers and all-road riders. Now you can choose between the versatile Standard casing, the superfast Extralight and the tough (but still lightning-fast) Endurance.

The 650B x 48 Switchback Hill was another obvious candidate for the Endurance casing. This is the tire that started the entire ‘Road Plus’ genre when we introduced it in 2015. It makes as much sense today as it did back then: A slightly smaller wheel size allows you to run a much wider tire, plus it maintains the nimble handling of a road bike.

This is the tire I run on all-road bikes like the Open U.P.P.E.R. and the Salsa Warbird – and it’s one of the reasons why these bikes can morph from road racer to adventure bike with a simple drop in tire pressure.

Our Antelope Hill was developed for bikepacking and adventures. It’s the perfect tire for riders who take their 29er on gravel (and even paved) roads. It’s been available with the Endurance casing for a while (above). Now we offer it with the ultra-tough Endurance Plus casing as well: Perfect for adventures where you don’t know what lies ahead.

To complement the new tires, we now offer Panaracer’s SealSmart tubeless sealant in a larger, more economical 1 liter bottle – useful when you are setting up multiple tires.

We’ve got the new tires and sealant in stock now, in limited quantities. Click on the images for more information or to order.

    Nice to see the panaracer sealant come on the market….but why low allergen? What does that even mean?

      Latex is an allergen, I’m guessing that’s what that is in reference to.

    Any plans to bring the 26″ x 2.3″ Rat Trap Pass with Endurance casing? and with dual-purpose knobby tread? Please?!

      I second the hopes that both the knobby and the endurance casing will find their way to 26″! That said, the standard casing has held up admirably given the abuse I subject them to…

    As I mentioned in a previous post, the Barlow Pass endurance are fantastic for tubeless road and gravel use in goathead country. I’m not sure the casing actually prevents any punctures, I pulled 60 out of one tire earlier this year, but the thicker sidewalls do not leak any sealant and tire pressure stays up better than extralight.

    The Panaracer sealant also performs well, sealing those 60 holes without needing to pump the tire, but I’m having a problem filling it. I fill through the valve, removing the core and placing a plastic tube from the bottle over the outer stem. I always shake the bottle well before filling, but often it stops flowing and I find the walnut shells have clogged up inside the stem. The good news is this probably means the sealant should seal a hole in the tire as big as the stem opening, but it is tricky to fill. Have you had this issue?

      Clogging valve cores are always an issue – the sealant does not distinguish between a hole in the tire and the valve… I use a Q tip after I replenish the sealant to clean out the valve stem as much as possible.

      I’ve set up a few pairs of RH tires now and I don’t even try to fill through the valve because it just clogs with walnuts. I pop off the bead for 4-6 inches and pour in directly from a small measuring cup. Good news is the sealant seems to work very fast on holes.

    Did you forget to print “TC” on the labels of the first two tires, or aren’t they TC?

    • Jan Heine March 10, 2020 at 2:57 pm #

      All Endurance casings are tubeless-compatible. So we decided to simplify the labels.

    Are all Rene Herse tires bias ply? It seems that most bicycles tires are bias ply. This seems at odds with the auto and motor bike industry that almost exclusively switched instantly from bias ply tires to radial tires when they were introduced due to their lower rolling resistance and better gas mileage (and other benefits) decades ago.

    I’m also going to lobby for a 559 knobby tire.

    • Jan Heine March 11, 2020 at 7:29 am #

      Several companies experimented with radial bicycle tires a while ago. We have some prototypes… The problem was a lack of directional stability – apparently not a problem with car and motorcycle tires, which use much stiffer casings.

    Are Rat Trap Pass tires your lowest selling tire? I use Rat TP tires on my circa 2000 US made Kestrel CSX, and like them quite a bit. If RTP tires do not sell well, then we will probably never see a knobby version?

    • Jan Heine March 12, 2020 at 4:00 pm #

      We don’t make what sells, but what we want to ride ourselves. And a knobby 26″ tire is something that would be perfect for my Firefly.😉

    Regarding sealant drying up, has anyone experimented with adding a small appropriate amount of water at certain intervals to keep the moisture content at the approximate correct amount?
