Another excellent Corbett Report
Not quite new technology, D1x has been around for over a year now. Still a very interesting and viable option for mtb riding.
“A tire set up tubeless won’t be faster than a lightweight inner tube, but also not significantly slower. The simple fact is that a tube, especially a lightweight one, is extremely supple and adds very little resistance. The sealant required to run a supple tire tubeless will cancel out the gains from eliminating the tube.”
When tubeless tires first became popular on mountain bikes, it was their resistance to pinch flats (above) that made them popular. Off-road, there are few nails or broken bottles that can cause punctures (and even those usually will be pushed into the soft ground rather than puncture the tire), but rims can bottom out on sharp rocks and other obstacles. So much so, in fact, that top mountain bike racers used to race on tubular tires – because tubular rims make pinch flats less likely. Eliminating tubes did the same, and while you still could ‘burp’ the tire, in general, tubeless allowed running lower pressures with fewer problems.
Many also believed that tubeless tires were faster. It made sense: an inner tube, even a thin one, added a membrane that flexed and absorbed energy. A tire without a tube had to be faster, even if only by a small amount! One big…

Pizzagate was just the beginning of the cracks opening in the floor, outing some of the more high-profile psychopaths. Alafantis, Podesta and Weiner. Pedogate then brought global awareness. Sadly, this is nothing new. The Vatican has protected pedophiles for over a century. The Royal Family is embroiled in pedophilia and trafficking as well. Hollywood elites, government officials, law enforcement and celebrities all have a penchant for the sick and disgusting practice of pedophilia.
This is just the beginning of uncovering the global pedophile ring that involves the US government, the British government, the Royals, the Vatican and many, many elites in politics and Hollywood. Stay tuned…
The minority, can deny, ignore and even defend the Deep State
at their own peril…
You may or may not wonder how much longer it will take for the majority of the mostly ignorant American populace to STOP accepting (AND championing) this corrupted, criminal enterprise, they happen to call ‘their’ government. This warmongering, murderous, pedophilia entity that presides over what has become a declining, massively unequal and divided nation. (If ever there was a once great nation, that is now a burgeoning shit hole, the US is certainly headed in that direction)
Amazingly as it seems, the majority of voters are STILL nothing but ideological statists who for whatever illogical reasons, cling to their useless, worthless party values. Be-it the scumbag democrats or the scumbag republicans. And make NO mistake those values are complete fucking garbage. The complete absence of any morals or ethics is beyond clear, yet…the muppetry continues.
“The shoulders of the tires are important for cornering traction.”
(this is what moto racers and riders refer to as ‘edge grip’ availability and performance)
To celebrate 15 years of Bicycle Quarterly, we are examining 12 myths in cycling – things that we (and most others) used to believe, but which we have found to be not true. Today, let’s look at tire tread.
“Bicycles don’t hydroplane,” declared some experts many years ago. “Hence, tire tread patterns don’t matter on the road.” The first part is true – even wide bicycle tires are too narrow to lose traction due to hydroplaning – but the conclusion assumes that tread pattern only serves to evacuate water from the tire/road interface.
The reality is more complex. I once cycled on the polished stone that surrounded a college library, and I was surprised by the lack of grip: I crashed. Even though I was unhurt, I learned the hard way that the coefficient of friction between our tires and the rocks that make up the road surface isn’t…
