The Barbieri Nana pump is a high performance pump that inflates tires up to 10 BAR and 142 PSI. Thanks to its compact size and low weight this pump can be used in competition. Good reliability is ensured by the use of carbon fiber and titanium. Complete with clips for attachment to the frame. The Nana’s superlight action allows you to pump with more strokes per second to make up for its smaller air volume. Made completely from carbon and titanium, the Nana’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 Nana works best for wide, low-pressure tires – above 60 psi (4 bar), pumping gets a bit harder. It weighs only 29 grams !!Specs: For Presta valves only Max. inflation pressure: 10 bar (142 psi) Weight: 29 g Carbon: barrel, plunger Titanium: cover Made in Italy

No. 78Winter 2021 Mauna Kea Test: Mason InSearchOf BQ Un-Meeting French Gravel Oregon Outback How to Wrap Leather Bar TapeAnother un-missable BQ, starting with the cover story: Donalrey Nieva and Karen Yung climb Mauna Kea. 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. Continuous center tread for optimum power transfeFile tread in the center for optimum braking (special request from our pros)Large side knobs for cornering tractionRound profile and gradual transitions—no cornering surprisesNoise cancelling for shoulder knobs—quieter than other tires with knobsLightweight: class-leading weight, like all RH tires (481 - 564 g, depending on casinDeveloped with gravel pros, input from Ted King, Brennan Wertz, Mazda Orange Seal Gravel Team Clincher, folding bead, Tubeless-compatible ISO size: 44 - 622 mm Recommended rim: 17 - 28 mm (inner width), hookless or with hooks Maximum pressure: 4 bar Actual width on 20 mm rim (internal): approx. 43 mm Actual width on 23 mm rim (internal): approx. 44 mm Extralight casing: +1 mm width Tubeless: +0.5 mm width Made in Japan The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse.

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.

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. This specification can only be used for handlebars up to 420 mm wide. Rene Herse Lightweight handlebars are made from slightly thicker, but still very light, aluminum to compensate for the longer lever arm of the wider bars. Heat-treated for ultimate strength All Rene Herse handlebars meet the most stringent EN “Racing Bike” standard for fatigue resistance. Polished (aluminum) finish Made in Japan 5 year warranty

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. 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.

At 48 mm wide, the Switchback Hill is Compass largest 650B (27.5″) tire yet. Switchback Hill is a climb on the 360 mile Oregon Outback gravel ride/race. The gravel is quite loose in places, and the extra floatation of the Switchback Hill tires gives you more speed and security when the going gets really rough. 30% of the Oregon Outback is on pavement, so we designed this tire to roll as fast and grip as well as a good racing tire. With this tire, you truly have the best of both worlds. The Switchback Hill is tubeless-compatible in both standard and extralight casing.All Models: Clincher, folding bead.

The ultimate tire for bikepacking and gravel adventures – and recipient of Bikepacking.com’s coveted ‘Gear of the Year’ award for the ‘Best New Component’. Developed together with bikepacking legend Lael Wilcox, the Fleecer Ridge measures 29″ x 2.2″ (or 700C x 55 mm), making it a perfect fit for bikepacking bikes.We name our tires after the passes that inspire them: Fleecer Ridge is the toughest climb on the incredible Tour Divide that traverses the Rocky Mountains from Canada to the Mexican border. On a ride that long, you’ll need a tire that can handle a huge range of conditions, from deep snow and mud via fast gravel to pavement as you descend into towns to resupply.The Fleecer 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. The Fleecer Ridge is the world’s first bicycle tire with noise cancellation: The staggered tread blocks create overlapping noise frequencies that partially cancel each other.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 Endurance Plus casing provides the ultimate in sidewall protection for extremely tough conditions.The Fleecer Ridge is tubeless-compatible. For tubeless setup, we recommend Panaracer SealSmart. When used with tubes, we recommend SV19 or SV19A tubes. Pro Tip: The noise cancellation improves further during the first 30 miles (50 km) as the sharp edges of the knobs wear off a little.
