With Donalrey’s stunning photos, this feature will make you want to head to Hawai’i and ride to its highest point yourself. Closer to home, we ride the Mason InSearchOf, an adventure bike that, according to its maker, is “in the #FastFar, #ContinentCrushing vein, but with steeper, rougher and deeper terrain well within its capabilities.” To test all aspects of the Mason, we venture out of our usual comfort zone onto some true mountain bike singletrack – and have a lot of fun. We bring you the story of three great rides on three continents: The BQ Un-Meeting was in California this year and saw a great group of riders, including the ‘Queen of the Wombats,’ mountain bike pioneer Jacquie Phelan (center). Adem Rudin tells the story and shares his photos. In Japan, we headed to the mountains to attend the 60th anniversary ride of the Alps Cycle Friends and marvel at some beautiful passhunters and cyclotouring bikes. Nicolas Joly takes us to the center of France. Sparsely populated, this region is home to 100s of (extinct) volcanos, 10,000s of cows, and an equally impressive mileage of gravel roads. Nicolas’ friends from the local bike maker Victoire charted a two-day trip that will make you dream of heading to France. We’ve updated our recommendations on how to find the right tire pressure. There are now two curves, since our tests show that there are two pressures that optimize rolling resistance. Which one you choose depends on the road surface and your personal preference. We also look at front/rear pressure, carrying loads and everything else you always wanted to know about tire pressure. Our projects show you the secrets of wrapping leather handlebar tape and – for advanced home mechanics – how to route lighting wires through your frame and rack.

At 48 mm wide, the Hatcher Pass hits the sweet spot between narrow gravel tire (38 mm) and mountain bike volume (55 mm) – ideal for the latest generation of gravel and all-road bikes. Named after Lael Wilcox’ favorite road in Alaska, this tire perfect for Hatcher Pass: The front side of the climb is paved and leads to Independence Mine (an abandoned gold mine that is now a state park). The back side is dirt. In August and September there are fields full of wild blueberries near the top. The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous. The Hatcher Pass is tubeless-compatible. For tubeless setup, we recommend Orange Seal.Rene Hersebanden zijn ontworpen met gedachte dat brede, soepele banden het meeste rijconfort geven. Rene Hersebanden hebben weinig rolweerstand, zijn snel en absorberen alle trillingen. De banden hebben goede grip in zowel droge als natte condities.

The Corkscrew Climb semi-slick is named after the biggest climb of the SBT GRVL race in Steamboat Springs, Colorado. Instead of distinct zones with different tread patterns, the slick tread transitions seamlessly into the side knobs, for better and more predictable grip as the bike leans into corners. The first row of side knobs is anchored on the center tread to stiffen the knobs for superior traction under extreme power—important when you sprint or climb out of the saddle and rock the bike from side to side. The knobs are arranged with our proprietary noise cancelling technology, making this tire almost eerily quiet for a gravel tire.The radius of the tread is significantly larger than the radius of the casing—effectively creating a tire that corners like a much-wider tire. This innovation also allows us to make the center tread thin and supple for ultra-low rolling resistance, while the tall side knobs provide superb traction when the tire sinks into the surface.

TPU tubes are easy to fix: Simply wipe the area with an alcohol wipe and stick on a patch. Push down with a tire lever to increase adhesion. No need to roughen the tube with sandpaper or use vulcanizing fluid. Patch kit includes 5 self-adhesive patches and 5 alcohol wipes. 5 pre-glues patches 5 alcohol wipes 11 g

Enjoy the performance and convenience of TPU tubes with the flat-proofness of tubeless—truly the best of both worlds. Rene Herse sealant is specially formulated to seal small punctures in TPU tubes. Since the sealant is enclosed inside the TPU tube, it lasts a long time before it needs to be replenished. The sealant only needs to seal punctures—and not the entire tire/rim interface—so you need much less sealant than you would for tubeless. Use this formula: Tire width (mm) = Sealant (ml) Example: For 38 mm tires, use 38 ml of sealant. Most riders add the sealant before they install the tube. Just remove the valve core and inject the sealant. The 100 ml bottle has a built-in valve core tool in the cap, and the nozzle fits onto the valve stem. You can inject the sealant directly out of the bottle into the tube. A clear strip with gradations on the side of the bottles make it easy to keep an eye on how much sealant you’ve injected. The direct injection bottle isn’t just convenient for home shop use. You can also inject sealant on the road. That way, you can run your TPU tubes without sealant for the ultimate in speed. If you have a flat, remove the valve core, inject the sealant, replace the valve core, inflate—and you’re ready to go without having to remove the wheel, take off the tire, find the hole, etc.

One of the most comfortable and beautiful handlebars ever made. Based on classic racing handlebars from the days when stages were long, with periods of easy spinning interrupted by fast-paced attacks and chases – just like many modern weekend rides.The long, flat ramps give you room to roam. Put your hands near the back for an upright position during easier efforts. Slide forward when it’s time to ‘put down the hammer.’ Ramps and drops are parallel, which makes for a very elegant handlebar and gives you room to move around – much-appreciated when you are facing headwinds.Pro Tip: Select your stem 10-20 mm shorter than you would with most handlebars, to compensate for the longer reach. Your position ‘on the hoods’ should be a little more stretched out than before, the ‘on the tops’ position will be a bit closer, and you’ll enjoy the long, flat ramps for an intermediate position. That way, you can fully benefit from the wide range that these bars offer.25.4 mm clamp. Also available with 31.8 Clamp. For 26.0 mm clamp diameter stems, use a Shim.Handlebar widths are center-to-center.Specs: Drops: 400/420/440/460 mm wide (center-center)Ramps: 360/380/400/420 mm wide (bars flare outward)Reach: 115 mmDrop: 125 mmClamp diameter: 25.4 mmWidth of clamp area: 35 mmWeight: Superlight: 281 g (400 mm); Lightweight: 336 g (440 mm)Rene Herse Superlight handlebars are made from extra-thinwall aluminum.

Pro racers have been asking us for a semi-slick—a tire that combines the speed of our slicks with the traction of our knobbies. They didn’t want a conventional semi-slick, but the same round profile as our other Rene Herse tires, for predictable cornering grip at all times—whether in a muddy gravel race or during a paved descent with ultra-fast hairpin turns.So we went about reinventing semi-slick tires. It took three years of R&D and resulted in three new patents. Instead of distinct zones with different tread patterns, the slick tread transitions seamlessly into the side knobs, for better and more predictable grip as the bike leans into corners. The first row of side knobs is anchored on the center tread to stiffen the knobs for superior traction under extreme power—important when you sprint or climb out of the saddle and rock the bike from side to side. The knobs are arranged with our proprietary noise cancelling technology, making this tire almost eerily quiet for a gravel tire.The innovations don’t stop there: The radius of the tread is significantly larger than the radius of the casing—effectively creating a tire that corners like a much-wider tire. This innovation also allows us to make the center tread thin and supple for ultra-low rolling resistance, while the tall side knobs provide superb traction when the tire sinks into the surface.Together with our supple casings, the result is a semi-slick tire that’s faster than most slicks on the market. We don’t use the word ‘revolution’ lightly—try these tires yourself and tell us whether you notice the difference!The Poteau Mountain is named after the roughest and most remote part of the Arkansas High Country Race. It’s a magical place, especially at night. The initial climb is ultra-steep and full of loose rocks. Rough boulder fields suddenly appear during the high-speed descents, adding to the challenge. The Poteau Mountain tire is perfect for adventures like the Arkansas High Country, which combine ultra-rough terrain with paved sections.The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous.

One of the world’s lightest pumps – and yet the Nuda can fill up even a large tire without your friends getting impatient as they wait. A Rene Herse exclusive, the Nuda minipump weighs just 30 g and fits in your handlebar or frame bag, yet inflates your tire faster than most other minipumps. The Nuda’s superlight action allows you to pump with more strokes per second.Cyclingnews.com crowned it “The best road mini pump for weight weenies” and commented: “If you’re preparing for an FKT, or a bikepacking adventure where the grams really start to add up, this would be an excellent option.”Made completely from carbon and titanium, the Nuda’s is superlight thanks to high-end materials and simple design, not because it is excessively fragile: The pump is rated to 142 psi (10 bar). Like most minipumps, the Nuda works best for wide, low-pressure tires – above 70 psi (4.8 bar), pumping gets a bit harder.The Nuda is the only pump you need for most rides, or carry it as a backup during truly epic adventures.Notes:Like most minipumps, the Nuda not intended for shop use, but for the (hopefully rare) times when you flat on the road.The O-Ring in the pump head rarely wears out, but if it does, it’s replaceable.The pump is assembled with two small Allen screws. They are not intended to be unscrewed – the tiny threads easily strip.Pro Tip: Compared to the even smaller and lighter Nana, the Nuda adds just 5 g in weight, yet pushes out 85% more air per stroke. (Use the tiny Nana if you want to carry your pump in your jersey pocket or small under-seat bag.)

Our most comfortable handlebar for all-day rides. The gentle curve of the ramps supports your palms better than a flatter handlebar shape. This eliminates pressure points that can lead to numb hands and pain in wrists and elbows. It’s a shape that was developed when races were long and roads were rough. We refined it so the shape ‘just right’ (unlike many similar bars that only raise your hands, but don’t really add comfort). Once you have ridden these, you won’t want to use any other bars for long rides. Pro Tip: Angle your Randonneur bars upward so the ramps are approximately flat. It’s key to enjoying the supreme hand comfort for which these handlebars are famous. Handlebar widths are center-to-center. All models (except 37 cm) Drops: 400/420/440/460/500 mm wide Ramps: 370/390/410/430/470 mm wide (bars flare outward) Reach: 115 mm (bars horizontal), increases as you angle the bars Drop: 140 mm (bars horizontal), decreases as you angle the bars 37 cm model: Drops: 370 mm wide Ramps: 295 mm wide (bars flare outward) Reach: 115 mm (bars horizontal) Drop: 135 mm (bars horizontal) Clamp diameter: 25.4 mm Width of clamp area: 35 mm Weight: Superlight: 296 g (420 mm); Lightweight: 339 g (440 mm) Rene Herse Superlight handlebars are made from extra-thinwall aluminum.

Named after an iconic cyclocross course near Seattle, the Steilacoom combines the supple casing of Compass tires with a knobby tread optimized for muddy conditions. The knob pattern is designed to pick up as little mud as possible. The knobs are widely spaced to clear the mud as the tire rotates. For riding on hard surfaces and pavement, the center knobs are staggered to offer good rolling. The large side knobs reduce squirm during cornering and make for a smooth transition without the sudden breakaway of most knobby tires. Even thought the Steilacoom rolls OK and corners fine on pavement, it is not intended as a road tire. Use the Steilacoom for rides where you expect muddy conditions – and cyclocross. The Steliacoom is tubeless-ready.All Models Clincher, folding bead Tubeless-ready Fast-rolling Excellent grip Superior traction Clincher tires with the ride of a good tubular Maximum pressure with tubes: 75 psi (5.2 bar) Maximum recommended pressure – tubeless: 60 psi (4 bar) Standard model Tan sidewalls Weight: 423 g Extralight model Ultra-light, ultra-supple casing Black or tan sidewalls Weight: 378 g Endurance casing: Further improved comfort and traction Extralight casing in a denser, stronger weave Protective belt under sidewalls and tread Ideal for rough gravel and tough conditions Dark tan sidewalls Weight: 445 g

The ultimate 650B bikepacking tire is designed for rides where you don’t know what lies ahead. Umtanum Ridge a steep and lonesome ridge in the central Cascade Mountains. It is so remote that European settlers never renamed it, and it carries its ancestral Native American name to this day. The Umtanum Ridge’s large and widely spaced knobs grip tenaciosly when conditions get tough. On pavement, it rolls and corners like a slick thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road. The Umtanum Ridge features our patented noise cancellation: The staggered tread blocks create overlapping noise frequencies that partially cancel each other. This means that on most surfaces, the Umtanum Ridge doesn’t just roll as fast as a slick – it’s also as quiet as a slick.All models feature: Clincher, folding bead Tubeless-compatible Maximum pressure with tubes: 55 psi / 3.8 bar Maximum recommended pressure – tubeless: 55 psi / 3.8 bar Actual width on 21 mm rim (internal): approx. 56 mm Actual width on 23 mm rim (internal): approx. 57 mm Extralight casing: +1 mm width Tubeless: +0.5 mm width Recommended rim: 17 - 40 mm (inner width; hookless: +1 mm) Standard casing Supple casing Tan sidewalls 580 g Extralight casing Ultra-light, ultra-supple casing The ultimate in speed and comfort Tan sidewalls 515 g Endurance casing The same ultra-fine threads as our Extralight casing, but in a denser, stronger weave Protective belt under sidewalls and tread Ideal for rough gravel and tough conditions Dark tan sidewalls 595 g Endurance Plus casing Extra-tough casing with ultra-strong threads Protective belt under sidewalls and tread The ultimate in sidewall protection Dark tan sidewalls 630 g Click here for a downloadable article on optimizing your tire pressure and tire installation instructions.

Finally Rene Herse's revolutionary dual-purpose knobbies are available in a 26″ version. Humptulips Ridge, the place that inspired these tires, is at the southern edge of the remote Olympic Mountains. A beautiful narrow gravel road climbs one side of the ridge, then descends the other, in an otherworldly loop that ranks among the best riding experiences anywhere. The Humptulips Ridge grips like a knobby when conditions get tough. On pavement, it rolls like a slick tire thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road.
