Tubeless Tire Technology

Tubeless tire technology in cycling has gained significant popularity due to its advantages in performance and puncture resistance. This technology, initially popular in mountain biking, has now expanded into road cycling and other disciplines. Here’s an overview of tubeless tire technology and its benefits:

How Tubeless Tires Work

  1. No Inner Tube: Unlike traditional tires, tubeless tires do not use an inner tube. Instead, the tire itself creates an airtight seal against the rim.
  2. Sealant: A liquid sealant is added inside the tire, which helps to seal the tire onto the rim and automatically repairs small punctures.
  3. Bead and Rim Design: The tire's bead locks onto the rim securely to maintain an airtight seal. Tubeless-ready rims are designed to support this feature.

Benefits

  1. Puncture Resistance: The sealant inside the tire can quickly seal small punctures from thorns, glass, or other sharp objects, reducing the likelihood of flat tires during a ride.
  2. Lower Pressure, Better Traction: Tubeless tires can be run at lower pressures without the risk of pinch flats (caused by the tube being pinched against the rim), which improves traction and comfort, especially on uneven surfaces.
  3. Reduced Rolling Resistance: Some studies suggest that tubeless tires have lower rolling resistance compared to traditional tubed tires, potentially improving efficiency and speed.
  4. Improved Ride Quality: The absence of a tube can lead to a smoother ride, as the tire can deform more during contact with the ground, absorbing shocks and bumps.

Considerations

  1. Installation: Setting up tubeless tires can be more challenging than traditional tires. It requires ensuring a proper seal and may sometimes need an air compressor to seat the tire onto the rim.
  2. Maintenance: Regularly checking and replenishing the sealant is necessary, as it can dry out over time.
  3. Compatibility: Not all rims and tires are tubeless-compatible. Ensure that both the tire and the rim are designed for tubeless setup.
  4. Emergency Repairs: While the sealant can handle small punctures, larger cuts may require a traditional patch or even a tube as a backup.

Applications

  • Mountain Biking: Tubeless tires are extremely popular in mountain biking due to their puncture resistance and ability to handle lower pressures for better traction.
  • Road Cycling: Increasingly common in road cycling for their potential to improve rolling resistance and comfort.
  • Gravel and Cyclocross: Well-suited for the variable and rough terrain of gravel and cyclocross racing.

Future Developments

As technology progresses, we are seeing continuous improvements in tubeless tire design, including better sealing technology, lighter and stronger materials, and wider compatibility with various rim types and sizes.

Adopting tubeless technology can offer a noticeable improvement in your cycling experience, especially if you frequently ride in conditions where punctures are a concern. However, it's essential to weigh the initial setup challenges and maintenance requirements against the performance and comfort benefits.

 
 
 

Comment of the Week: Attorney Chris Thomas on recreational immunity

Attorney (and BikePortland advertiser) Chris Thomas of the Thomas, Coon, Newton & Frost law firm, shared his expertise on liability in the comments section of our recent post about a case involving Oregon’s recreational immunity law: “In fact, recreational immunity is alive and well,” wrote Thomas.

Podcast: Portland City Council Candidate Jesse Cornett

Jesse Cornett is running for District 3, which encompasses (roughly) southeast Portland from the Willamette to 82nd, and I-84 to the southern border. He’s an intriguing candidate, not just because he was a “body man” for Senator Bernie Sanders and worked on his presidential campaign, but because of his long political resume here in Oregon. In 2008 he narrowly lost a race for the Oregon State Senate and in 2010 he ran for Portland City Council. I interviewed him during that campaign, so it was fun to sit down with him again today — 14 years later.

Our conversation touched on a wide range of topics, from policing to homelessness — to whether or not Portland’s goal of 25% cycling mode share by 2030 is possible.

Check out a few of our exchanges below:

If you’re on council would you support the idea of reducing space for driving so that we can put other things in its place?

Cycling Pitfalls

Cycling, whether for recreation, fitness, commuting, or competitive sport, comes with its share of pitfalls. Being aware of these common issues can help cyclists prepare better and enjoy their rides more safely and effectively. Here are some of the key pitfalls to watch out for:

  1. Inadequate Preparation: Not having the right gear, failing to plan your route, or not checking the weather can lead to uncomfortable or even dangerous situations.

  2. Neglecting Bike Maintenance: Regular maintenance is crucial. Issues like improperly inflated tires, worn brake pads, or a poorly lubricated chain can lead to accidents or breakdowns.

  3. Ignoring Traffic Rules: On the road, cyclists must follow the same traffic laws as motorists. Ignoring signals, signs, or right-of-way rules increases the risk of accidents.

  4. Inadequate Hydration and Nutrition: Especially on longer rides, failing to hydrate properly and not having enough nutrition can lead to decreased performance and health risks like dehydration or hypoglycemia.

Hi! I’m Erin and I’m excited to move to Portland

My necessities for a recent housing search in Portland… and the front rack bag I crammed it all into. (Photos: Erin Bailie)

Hi! I’m Erin Bailie, and I’ll be moving from Seattle to Portland (Sullivan’s Gulch neighborhood) in February. By day I work a tech job in product/research, and I love using bicycles as my primary means of transportation. In my 30-something years I’ve lived a lot of bike lives: I’ve been bike commuting since second grade, sometimes I do track racing or go bikepacking, and I love Pedalpalooza. Reading BikePortland has been part of my morning routine for years, and I can’t wait to chronicle some of my thoughts as a newcomer to town. 

Though my husband Jonathan and I will be new to Portland, Portland won’t be new to us. Over the past few years, we’ve found any excuse we can to visit for the weekend. We’ve driven, taken Amtrak, and once we even rode the whole way to Portland (thanks, STP!). When the opportunity knocked for Jonathan to take a job in Portland, we couldn’t say “yes!” fast enough. 

The month before our move, we spent a week in Portland with the sole purpose of finding housing. Each day played out in a chaotic frenzy: I crammed my necessities and laptop into a front rack bag and rode from our lodging in Richmond, to rental showings across northeast and southeast, to co-working spaces to dial into meetings — and tried to find a gluten-free lunch somewhere along the way.

Oregon trails in jeopardy as confusion reigns over ‘recreational immunity’ law

A law that was created to shield land managers and property owners from liability claims is under fire and public trail access — including bike trails — across Oregon could be in jeopardy. That’s the state-of-play due to a decision in July 2023 by the Oregon Court of Appeals in a case that hinged on the legal concept of, “recreational immunity.”

Oregon’s recreational immunity law (ORS 105.682) states, “an owner of land is not liable in contract or tort for any personal injury, death or property damage that arises out of the use of the land for recreational purposes.” The idea behind this law is to encourage landowners (government entities or private companies/individuals) to keep trails open to the public without fear of being sued if someone is hurt using them.

Challenges to this law have happened before, but one if its biggest tests yet began when a woman slipped on a trail and broke her leg while walking near Agate Beach on the Oregon Coast in 2019 and sued the City of Newport for damages, saying the law shouldn’t apply because she wasn’t recreating at the time of her fall. Nicole Fields claimed the city was negligent because they failed to maintain a footbridge on a trail that led to the beach. Her lawyers argued their client was using the trail as an access route to her recreation — and was not technically recreating —  when she fell. A local judge didn’t accept that argument and ruled in favor of the City of Newport. But last summer, the decision was reversed by the Court of Appeals. When the Oregon Supreme Court refused to hear an appeal to the case in October, it raised questions about how to apply this important law.

Some cities and land managers are confused and worried that they will no longer be shielded from lawsuits if they keep trails open. According to the Salem Statesman Journal, several coastal cities have already closed trails and paused trail projects already. The Journal also reports that some legal experts feel closures are an overreaction, spurred by insurance industry scare tactics.

Time to brighten your mood with Winter Light Fest rides

(Photo of a 2023 WLF ride by Dylan Evanston.)

After several days holed up at home and frozen, the thought of biking through the city with friends, gazing at creative light displays, and being entertained by people holding fire sounds mighty fine right about now.

If that sounds cool, you’ll be happy to know that the program for the annual Portland Winter Light Festival (PDXWLF) was announced today. What is PDXWLF? The nonprofit Willamette Light Brigade, the organization that hosts the event, puts it like this:

“PDXWLF brings art, technology, and inclusivity together, invigorating Portland in the winter. With free admission, the festival fosters community and showcases captivating light installations, projections, and interactive displays, creating an immersive experience for all attendees.”

The event is a collection of over 200 illuminated art displays throughout the city — and a bicycle is the best way to see them all! In fact, cycling is such a good match for this festival that organizers have released seven routes curated specifically for riders, put together by ride leader and BikePortland contributor Tom Howe.

PBOT will manage new food truck program to activate downtown sidewalks

Slide shown by PBOT right-of-way manager at City Council this morning.

“This will increase the walkability of the Central City Plan District and decrease the need for auto-oriented transportation.”

Mingus Mapps, PBOT commissioner

Portland City Council voted unanimously at their meeting this morning to green light a new pilot program that will bring more mobile food trucks to the the central city. The program is expected to help revitalize downtown, the Lloyd, and the Central Eastside, by allowing food truck operators to park adjacent to sidewalks and do business in the public right-of-way — a practice current city code prohibits.

The program will be operated by the Portland Bureau of Transportation (PBOT) as an expansion of their Healthy Business permit program that was launched during the pandemic as a way to help businesses expand operations into the street. That program also began as a pilot and was recently made permanent.

The ordinance means PBOT receives a nearly two-year waiver from having to comply with existing city code 14A.50.040 which states, “It shall be unlawful for any person to sell or attempt to sell any merchandise or services in or upon any sidewalk, street, alley, lane, public right of way, or under any bridgeway or viaduct within the Central City Plan District.”

Cycling Tracking Technology

Cycling tracking technology has advanced significantly, offering cyclists of all levels detailed insights into their rides and performance. This tracking technology encompasses a range of devices and applications, each with unique features. Here's an overview of how cycling tracking works and the types of technology involved:

  1. GPS Bike Computers: These devices, mounted on the handlebars, use GPS to track the route, speed, distance, and often elevation. Brands like Garmin, Wahoo, and Lezyne offer popular models. They can provide real-time data, navigation, and even connect to third-party apps.

  2. Smartphone Apps: Apps like Strava, MapMyRide, and Komoot are widely used for tracking cycling performance. They use the smartphone's GPS to record your ride and can provide a wealth of data, including speed, distance, elevation gain, and route maps. Many of these apps also offer social features, allowing users to share their rides and compete with others.

  3. Wearable Tech: Devices like fitness trackers and smartwatches (e.g., Fitbit, Apple Watch, Garmin) can track cycling activity. They often include features like heart rate monitoring, GPS tracking, and the ability to sync with other cycling apps or devices.

  4. Power Meters: For more serious cyclists, power meters are a valuable tool. They measure the power output (in watts) of the rider, which is a direct indicator of physical effort and performance. Power meters can be built into the bike's crankset, pedals, or wheel hub.

Four months after 43-year-old Rose City Park neighborhood resident Jason Ruhmshottel was killed in a traffic collision, his family is still searching for closure and answers. 

According to his sister, Christina Cuanalo, Jason spent his free time playing video games, collecting Funko Pops, and reading. He loved 80’s horror villains such as Freddy Kruger and his favorite author was Stephen King. He ate healthy, but had a weakness for See’s Candy and ice cream. He loved coffee and would rave about a new ground he tried. 

Jason lived in Portland his entire life. He attended Jefferson High School and moved to an apartment near NE 53rd and I-84 in 2016. With a degree in Criminal Justice from Portland Community College, Ruhmshottel worked for the Transportation Security Administration at the Portland Airport before switching jobs in to work as a security officer at the Columbia Sportswear warehouse off of North Marine Drive. 

Estimated view of driver on N Portland Rd. Jason was coming from the right.Looking northwest at the collision point with bike path on the left.

Jason worked the graveyard shift at the warehouse, which is located adjacent to the Smith and Bybee Wetlands Natural Area. When he began that job, he commuted via TriMet bus and walking — a journey Google Maps says takes one hour and 37 minutes. But four years ago, a close family friend gave Jason a bicycle and he began to ride it every day.

A university based in Barcelona, Spain has released the first-ever report on bike bus efforts around the globe.

The report, from the City Lab Barcelona research group at Institut de Ciència i Tecnologia Ambientals de la Universitat Autònoma de Barcelona (ICTA-UAB), summarizes key findings from interviews with 22 bike bus leaders in eight countries. 

Bike buses took off in 2021 when a Barcelona effort went viral online. But, according to this new report, the organized bike bus took place in Brecht, Belgium in 1998. “Today, Bike Bus has evolved from a set of isolated initiatives into a global movement that aspires to influence city policy and participate in the global conversation about building child-friendly cities.”

Wild winter weather check-in

Readers Emily (left) Bradley (center) and Josh are making the most of the snow.

How are you doing with this wild weather?

What started as a dusting of snow, high winds, and record-setting cold temps Saturday has turned into a major weather event in Portland. There have been several deaths, lots of damaged property, school and business closures, and thousands are still without power. Folks who rely on TriMet have had a rough go as closures of the light rail system have wreaked havoc on some commutes.

As I type this Tuesday morning a possible ice storm is due to bear down on our city before the day is done. 

I’ve seen many posts of people bicycling and most roads are relatively rideable; but I haven’t been out much since Sunday morning. The photos I’ve seen of Mt. Tabor are heartbreaking! So many beautiful trees are gone, but even worse is the destruction of the big, covered picnic area near the start/finish of the Mt. Tabor series races.

Comment of the Week: We’ve found the voice of southwest Portland!

Nothing stings like satire. Writing in response to our StreetsPDX and southest Portland’s sidewalk problem post, “Young SW Advocate-in-Training” brought some comic relief, and maybe even thrust a dagger or two into the heart of some zombie tropes about southwest that just won’t die. In training as an advocate? I’d say sitting on the knee of Jonathan Swift.

Here’s what Young SW Advocate-in-Training had to say:

As a parent and a resident of SW Portland, I was heartened to read about PBOT’s new Safer In Cars Initiative. Formerly the Safe Streets Initiative, this new direction will be better aligned with our existing infrastructure, our current transportation investments, and our society’s values.

Let’s face it, in SW Portland, it’s not safe to have your children walk or bike anywhere. Our kids belong in the back seat of our car. The benefits are immense. First, driving in a car is a much healthier option than walking or biking once you consider SW Portland’s lack of sidewalks and the inertial difference between a four-year old and an Amazon delivery truck. Second, sidewalk infill projects that encourage active transportation are not good for the environment due to the negative impacts of increased storm water. Third, the future is digital, getting kids outside could mean an awkward face to face social interaction. This only slows their progress in developing digital relationships from the safety of their own homes (or back seats of our cars!). And finally, reducing or altogether eliminating sidewalk infill projects can help bridge the $500M funding gap for critical and more beneficial projects like the I-5 Rose Quarter project so we can get people back to their Southwest Washington tax havens 5 minutes quicker.
