We rode 26x2 inch Duremes on our tour this year, which we just finished. Midwest US: Iowa>Minnesota>Wisconsin>UP Michigan>Michigan. A mix of roads and trails, 1800 miles. We ride a tandem and camp. No flats and the wider tires were great for the mix of conditions. I very much appreciate other peoples comments that these are one of the best touring tires ever made.
As many of you are aware, these Duremes are a special production batch for SJS. I was going to purchase more tires after the high Covid-induced shipping costs reduced, but SJS has since sold out. I have contacted SJS and they responded that they might commission another batch next year. You may wish to add you voice to encourage another production run.

Running a pair on my tandem too. Good all round tyres that handle most surfaces well. Not had a visit from the puncture fairies yet either (Touch wood ! ) Got a spare in waiting..

Dear Hendrich,
pressing sjs not to discontinue the duremes is an excellent idea, I was going to do the same (after watching a youtube clip where the quality of the duremes was celebrated).
Who did you talk to specifically at sjs?
-
lorenzo,
thanks for your interest. John from SJS said "Not anytime soon I'm afraid- maybe sometime next year?" Hopefully they will! The Duremes are awesome.
-
hi Henrich, I will send sjs an email just to convey the idea that there is market interest in such tires. I suspect the disappearance of duremes has more to so with supply problems due to covid than anything else. There is clearly a shortage of tires. And I have been waiting for the restocking of Thorn’s cranks for almost one year!
-
ups. sorry, Hendrich ;D
-
Lorenzo, if I understand correctly. Schwalbe discontinued the Duremes some time ago, but SJSC/Thorn thought so highly of the tire that they had a batch made specifically for SJSC. That batch has recently sold out, and with interest in 26" fading, SJSC will think about demand before paying for another batch. Perhaps the year wait is due to covid problems with manufacturing. Nevertheless, it would be good to let SJSC know there is still demand.

Hey Mike, good on yer for making such a tour this year! I envy you & Susan. Hoping I might be able to do a mini-tour in W Québec in late Aug/early Sept.
And good luck nudging SJSC for another batch of Duremes.
I have to believe that's doable, tho' the final decision may rest with Schwalbe...
Cheers, John

Hi John,
Many interesting things along the tour, including Sand Hill cranes...always stunning to see such large birds. I have journaled some of our trips in past, but I find it tedious, perhaps cycleblaze. If we can enter Canada next year, Gaspe is in our sites again. Good luck with a tour in late August, sounds wonderful. Route Verte I presume?

A quick note on Duremes. I have a couple Duremes that I bought several years ago, very nice rolling tire, 50mm wide. Then later saw one on a website at a clearance price and bought one more, that one is much stiffer and slower rolling.
The first ones I got are labeled Double Defense, the slower one I bought later is labeled Tandem Ready in red print.
I do not know what the special batch that SJS got was, I did not buy from that batch.
I am just pointing out that there have been different Duremes over time. The "Double Defense" ones I like how well they roll, the "Tandem Ready" one was at a price that I can't complain but I am not sure if I will ever be happy with it. I might use that on front next time I do a really heavily loaded tour on my Nomad Mk II.
I just took a photo that shows the difference in labeling.

I have 6 wired-on Duremes mounted to 3 bikes including my tandem and I have 2 more with the folding/Kevlar beads as take-along spares.
I like them because they roll well, last a long time, are very puncture resistant and the tread is a good all-'round compromise between lighter road slick (think: Supreme) and something heavier like the old Mondial. They also de/mount easily for me on my Andra 30/40 rims and don't require even a single tire lever for either operation.
What I don't like is the wobble present in every single one of them. It isnt a huge wobble and doesn't make a functional difference but sure is annoying if I happen to look down while underway and see. The tread just isn't set square on the casing. The beads are fully and evenly seated so it isn't mounting error. This lack of precision on an otherwise great tire disappoints me -- so I don't look at them, just ride! ;D
My $20 Innovative Swiftor tires (an excellent low budget choice in a 26x2.0 tire) run true as a die on the same rims.
Anyone else notice a wobble in their Duremes?
Best,
Dan.

I find that a handlebar bag and a fender does an exceptional job of preventing me from being bothered by such wobbles.

:D ;D ;D :D
Nice one, George. That's one of the reasons I extended the front fender/mudguard on my Nomad! ;)
All the best,
Dan.

Agree. But 50 mm Supremes are a tad lighter, roll slightly better on tarmac, last a long time, have been very puncture resistant so far and are also easy to de/mount without tyre levers. And though I mainly use tarmac roads, they have (so far) coped with some seriously rocky off road tracks despite their rather fragile-looking sidewalls.
So I have Supremes on most of the family bikes, keeping my Duremes in case I do a tour involving a lot of off-road riding, where they would be more suitable. I also used Duremes for survey work, which was mostly off road on paths and tracks.

My 50 mm wide Supremes and Duremes all have a noticeable wobble if I bother to look. But no noticeable wobble on the 42 mm Supremes on my wife's bike and my Raven Sport Tour.

George, the Duremes I have are from the special SJSC batch and are labeled "Double Defense Evolution Line" with no other markings for tandem. I also have supremes, the suppleness (is that a word?) is comparable to the Duremes. The Duremes do roll well, and quiet for a tire that can also handle trails. On tour, we are often seeking trails to ride if not an ATV path, so I appreciate the multi-surface capability.
Regarding wobble, seems that most tires with a white line tend to make imperfections more noticeable, but the function is not affected. Our Planet Bike Cascadia mudguards were great in heavy rain, low in front keeping water off my feet, and perhaps masking the wobble:)
We use Andra 35 rims, which seem ideal for 2 inch. I built the wheels since the wheelbuilders in the US do poorly with Rohloff.

Sounds like the special batch that SJS got were the good ones then.
The Tandem Ready one I got also says double carcass, so that likely explains the stiffer sidewalls. And that is why I might put it on the front if I do any more off road tours with my Nomad Mk II.
My Sherpa, if a tour is likely to be almost all on pavement (tarmac), I use 40mm wide Marathons (with Greenguard). But if there might be a significant amount of gravel or off road, I use 50mm Dureme (Double Defense) on front and a 50mm wide Marathon Extreme in rear.
My Nomad Mk II, my past tours were on Marathon Extremes front and rear, 57mm wide. But I could see using my Tandem Ready Dureme on front on a tour with that bike. I suspect that the double carcass would make it a bit stiffer and slower than the 57mm Extreme, but I like having my most robustly constructed tire on front.

Mike,
"Suppleness" is indeed a word, and a good one too!
If we can enter Canada next year, Gaspe is in our sites again. Good luck with a tour in late August, sounds wonderful. Route Verte I presume?
You can enter Canada w.e.f. Monday, Aug. 9. No quarantine if you're doubly vaccinated, tho' a COVID test is required. So you should be Ok in 2022, as well. Be wise to re-check come spring, tho' ;)
Give a shout if you will be cycling the Gaspé. I didn't do a journal on our circuit in 2010, but I still have quite a few notes on accomm, campsites, etc. Do make sure your brake pads are in good nick. I'd go counter-clockwise to avoid 17% and 24% climbs -- but your brake pads will be tested by the corresponding descents!
My mini-tour-in-the-planning will incl a couple of bits of Route verte sections. There are good regional routes in Qué, tho', which intersect with la Route verte. In the Ottawa Valley, we have several, some of which criss-cross the river into both Ont & Qué. A recent one is the 800 km "Log-Driver's Waltz" bikepacking route.
The Valley and its tributaries on both sides have a long history of logging, now embedded in both popular and official culture.
"The Log-Driver's Waltz" is a delightful song by Wade Hemsworth (who also penned the (in)famous, "The Blackfly"). This, from the National Film Board, features a duet by the young Kate and Anna McGarrigle: https://www.youtube.com/watch?v=upsZZ2s3xv8 (https://www.youtube.com/watch?v=upsZZ2s3xv8)
Malak Karsh, photographer extraordinaire, lived and worked in Ottawa for decades, and created compelling photos of the draveurs' life on the rivers and neighbouring landscapes. (His brother, the more famous Yousuf, did portraits, good 'uns to be sure, but I found his subjects intrigued me far less than Malak's.)
Cheers, J.

Great video! I whitewater kayak and learned early on to avoid "strainers", which are trapped logs on a river and are deadly. The log drivers make my head spin.
Our plan (next year) is to add a loop of Saint-Jean lake to the Montréal/Gaspe loop. Perhaps CCW this time, although the prevailing western winds along the St. Lawrence are nice for CW direction. I found a map of the Log-Driver's Waltz trail. Is it mostly single track with a dirt surface, not so good for standard pannier-tour bike? There is a route verte from Ottawa to Montréal along the Ottawa river. Have you rode this, what's your opinion of it?

Thanks, Mike.
With gigantic apologies, I mixed up my clock-directions for the Gaspé: I did my circuit clockwise: Starting in Matapédia & heading N & E to Matane, then E along the N shore of the Gaspé, S round the tip, then W along the coast of Baie des Châleurs to finish up in Matapédia.
There was one tough climb near the NE tip of the peninsula, about 12-14% if memory serves. But, we encountered a 17% downhill in that area--meeting a couple of cyclists climbing, and I thought, "So glad I'm going downhill!"
There was another fierce downhill towards Gaspé village; and then, further along the South Shore, there was a 24% downhill into Percé village. My buddy Jim & I ducked that, deciding to take the truck route instead; and happily, there weren't any trucks that day.
The winds can blow W-to-E in the morning, and then flip 180 degrees at midday...That happened to us on the N Shore. On the S shore, we did 140 kms one day with a tail wind, starting just W of Gaspé village. A day later, we did 60 kms in 6 hours, after the tailwind flipped overnight :(
I've not ridden the loop to Lac St-Jean, but I'm told it's splendid.
(One thing you might consider: have a listen to the songs of Gilles Vigneault, Québec's national poet/chanteur. Two I'd recommend are: "Mon pays" and "Gens de pays". For many of a certain generation, the latter is a national anthem. You can get the French lyrics easily enough; the English version works quite well for "Mon pays", less so for "Gens de pays". If people learn that you know Vigneault's songs, they'll be surprised and delighted.)
On the "Log-Driver's Waltz" trail, I understand it's a mix of quiet tarmac, gravel, some logging roads, and some single-track. My route will be secondary/tertiary tarmac & some gravel. Can send you a map when I get it done, if you're interested.
I've travelled part of the Rte Verte #1, along the Ottawa River E of Ottawa/Gatineau towards Papineauville & the Chateau Montebello. (Ottawa is on the Ontario side of the river.) It's a mix of quiet roads & bike paths, all well-marked. There are some stretches on Hwy 148, the original main road beside the river, but those all have well-surfaced wide shoulders. (Québec generally is far superior to Ontario in providing paved shoulders for cyclists. The Rte Verte people have done their work well.)
Cheers, John
