If you have a carbon frame bike that also uses a carbon seatpost you might find you have the problem of your seatpost slipping down over time, which is very annoying and also means your seatpost will get scratched, but also messes up your riding position. So let’s have a look at a few ways to fix that issue!

Five different bikes make the list in a disparate year of riding
It’s that time of year again. Summer has faded, the Black Friday bonanza has been and gone, the Christmas music is blaring (it has been since mid-November, don’t email me), and it’s the point in the year when we get to reflect back on our year of riding, racing and reviewing all the tech that the bike industry has to offer.
For me, 2023 has been a quiet year of on-bike achievement. It’s been fairly busy here at work, especially in the first half of the year which saw me heading overseas at least once per month between February and August. Combine that with a new puppy taking up a lot of my spare time and a wedding on the horizon to save up for, I’ve not managed much-structured training, racing, or any really big rides this year.
Most of my riding at home has been done indoors (alongside testing various smart trainers). Although I spent a good number of summer days on a mountain bike that was loaned to me by Giant, and that reignited a love for riding mountain bikes, something I’ve not done since I was around 16; almost half a life ago.

In October, Micromobility America brought a two-day conference and trade show of alternative transportation to Richmond, California. Exhibitors included manufacturers of a range of e-bikes and scooters, app developers, and even representatives from the U.S. Department of Transportation. CalBike participated in one of the many panel discussions, and you can view the recording below.
Our panel was titled How Cities Can Incentivize Electric Bikes and was expertly moderated by Colin Hughes. The panelists were:
- Ed Clancy from Pedal Ahead, which is administering the statewide E-Bike Incentive Program
- Heather House, a manager at the Rocky Mountain Institute, which has developed a tool for cities to measure the impact of e-bikes on reducing greenhouse gas emissions
- Kerby Olson, new mobility supervisor at OakDOT, which is preparing to introduce a local e-bike program
- Brett Wiley, senior program associate at East Bay Community Energy (since renamed Ava Community Energy, providing green energy in the San Joaquin Valley as well as the East Bay), which is planning an ambitious e-bike incentive program for its customers
- Laura McCamy, communication specialist and e-bike advocate for CalBike.
Slamming stems or spacing them to fit? Riding Zwift on maximum difficulty because the power feels all off? Is there a way to put pressure sensors into a shoe insole? How many watts does a ticking disc brake rotor actually take away? Numb feet after switching to cleats! All this and more are answered in this week’s GCN Tech Clinic.

My summer bike is a Specialized Tarmac SL6. Even though it has disc brakes, I’m hesitant to expose it to the salted winter roads. I want to keep the more expensive parts lasting longer, yet I’m not keen on spending the whole winter locked up on the turbo. Therefore, I’ve been on the lookout for a suitable alternative bike that can handle the winter conditions.
Many people invest in a cheap bike that they don’t mind abusing over the winter months, but I’ve gone down an alternative route and picked up a 2018 Specialized Diverge Comp with SRAM Force 1 from Facebook Marketplace instead.
Specialized first introduced its Diverge in 2014, and for the 2018 model year it gave the Diverge a complete overhaul. The bike is designed for road and off-road riding, featuring Future Shock suspension which provides 20mm of basic suspension. It also has tyre clearance for tyres up to 42mm and ‘Open Road’ geometry, which was an attempt to move away from traditional cyclocross geometry to differentiate the gravel and ‘cross genres.

What San Francisco and Oakland can learn from Los Angeles… yes, Los Angeles
By Roger Rudick
Los Angeles closed seven miles of the Arroyo Seco Parkway for one Sunday last month and let people use it for cycling, walking, and just having a good time. From our sister publication, Streetsblog Los Angeles:
…tens of thousands of Angelenos did the unthinkable: enjoyed spending time on a freeway. Arroyo Fest 2023 removed cars from about seven miles of the 110 Freeway, known as the Arroyo Seco Parkway. Instead, the freeway was filled with people on foot, on bike, on skates, on scooters.
San Francisco, of course, has Sunday Streets, one of the earliest and most successful and celebrated examples of a temporary conversion of car space for other uses. The Bay Area also boasts the annual “Niles Canyon Stroll & Roll,” which removes cars from a stretch of highway 84.
San Francisco has its Marathon closures. And the Golden Gate Bridge was famously closed to traffic in 1987 for its 50th anniversary. But there’s no equivalent to “Arroyo Fest,” where the city closes a freeway for pure recreation.
The two places to do it seem screamingly obvious.
The first is the stub of the Central Freeway and 101. The city is already talking about removing or undergrounding these freeways, which are in need of seismic retrofits or removal. The other is I-980 in Oakland. 980 is one of the top candidates for removal on the Federal government’s “Reconnecting Communities” program.
Ollie and Hank decided to enter the biggest bike race in America, El Tour de Tucson. At 100 miles long, this was a test of endurance, but also speed. They tried to break the 4-hour 100-mile time barrier. Will Ollie and Hank manage to hit their target or fall behind the peloton?

WORDS: JAMES WITTS
‘Tis the season for cherubs, cheese, Christmas cake, and cyclocross. Yes, up and down Great Britain and beyond, once passive fields are churned up into a quagmire by the knobbly tyres of (visually) beefed-up road bikes. It’s wonderful and exhausting in equal measure. “I’ve never tried it,” you ponder. Well, make this the winter that you do as you’ll enjoy a competitive boost to your 2024 season.
“But I haven’t a clue about the technical, psychological and physical benefits of this historic discipline of cycling that, legend has it, stretches back to the early 1900s and beyond as European road racers would race each other through tut farmer’s fields and over tut fences,” you ponder further in a rather laborious fashion. “Please tell me more with the help of current UCI World under-23 cyclocross champion Shirin van Anrooij, plus explain the transferable benefits to my 2024 road season.”
As you’ve pondered so nicely, we’re on it…
SCIENCE OF SPEED
Cyclocross dominates the cycling calendar in autumn and wintertime, and commonly plays out over a course that’s one to three kilometres long in races lasting between 40 and 60 minutes. The off-road parcours include sharp turns, steep banks, tree roots, sandpits and hurdles. Those latter two obstacles mean dismounting and running with a bike nestled on either shoulder is a much-needed skill. You also need the lungs, heart and legs of a thoroughbred as though the racing ‘only’ consumes an hour compared to a road race or sportive that can roll on for five or six hours, the intensity is all out.
How intense is highlighted by a 2017 study in the journal Sports and Exercise Medicine. A team led by Ryanne Carmichael, associate professor of exercise and sports physiology at Plymouth State University, USA, had eight experienced crossers take part in both a lab test and a cyclocross race.
In the lab, they pedalled to exhaustion on a cycle ergometer, the researchers measuring a number of metrics including lactate production at the increasing intensities. Broadly, the fitter you are, the higher your power output while keeping lactate levels low. In Carmichael’s study, heart-rate intensities were categorised as low, medium and high where low equated to lactate levels of 2mmol/litre or under up to high at 4mmol/l or over.
Join us for the last event of the 2023 season, CicLAvia—South LA (Leimert Park <—> Historic South Central) on Sunday, December 3rd, from 9am – 3pm as we transform the streets of Leimert Park, King Estates, Exposition Park, and Historic South Central into a public park for the day.
The South LA area is rich with African American culture, especially in its food, art, and architecture. Here are some of the MANY local gems that will be along the route.
And our friends at Los Angeles Conservancy have designed an interactive scavenger hunt for CicLAvia participants to explore the history surrounding your ride through historic South L.A. neighborhoods. Stop by any CicLAvia info booth for more information on how to participate. Local Gems marked with an asterisk (*) are part of the challenge and are also open to all visitors throughout the day.
