I've never seen that either, but I believe there was a product liability law suit over it. https://www.jvra.com/verdict_trak/article.aspx?id=28254 ARTICLE ID 28254 $ - PRODUCT LIABILITY - DEFECTIVE BRAKING SYSTEM ON MOUNTAIN BICYCLE - FAILURE OF MAIN BRAKE CABLE - CABLE CATCHES IN KNOBBY TIRE - PLAINTIFF THROWN OVER HANDLEBARS - CERVICAL FRACTURE - QUADRIPLEGIA TO 24-YEAR-OLD. Philadelphia County, Pennsylvania This was a product liability action brought by the male plaintiff, age 24 at the time of injury, against the retailer, manufacturer and component part manufacturer of a Raleigh Pointe Mountain bicycle. The defendant retailer and manufacturer settled with the plaintiff for a combined total of $4.5 million and agreed to continue to trial. The plaintiff claimed that the brake and cable of the bicycle, manufactured by the defendant component part manufacturer (Shimano, Inc.) was defective in that the pulley and brake cable were incompatible. The plaintiff also alleged that the bicycle lacked a method to prevent the cable from entangling in the knobby tire in case of a break in the line. The plaintiff claimed that the main cable broke, the straddle cable became caught in the front tire and caused the plaintiff to fly over the handlebars. The plaintiff was rendered a permanent quadriplegic as a result of the accident. The defendant, Shimano, argued that the cable break was caused by an inappropriate size pulley installed by the co-defendants who manufacturer and assembled the bicycle. The defense also denied that the plaintiff flipped over the front handlebars and contended that he lost control of the bicycle and struck a car. Evidence showed that the defendant, Shimano, manufactured the cable and brake system used on a mountain bicycle which the plaintiff had purchased new within a year of the accident. The plaintiff testified that he was coasting his bike to a red light and applied the front hand brakes. The plaintiff’s accident reconstruction expert/biomechanical expert opined that the front main brake cable on the bicycle failed on the pulley, the straddle cable became lodged in the front tire, the bike stopped suddenly and the plaintiff pitched over the front handlebars. This expert also testified that a dent in a car positioned next to the bicycle at the time of the accident was pre-existing and not caused by impact with the bicycle. The bike’s rear tire merely touched the vehicle leaving a tire impression, according to this expert. The plaintiff was not wearing a helmet and the plaintiff’s expert also opined that a helmet would not have prevented the plaintiff’s cervical injury. The plaintiff’s metallurgist testified that the main brake cable fatigued because the brake pulley was too small. The pulley/cable incompatibility was an engineering and design defect, according to the plaintiff’s expert. The plaintiff’s bicycle industry expert explained that there are three ways to guide the brake cable on a bicycle: a pulley, a cable hanger or to bore through the handlebar stem. The pulley system was an intended use for the integrated cable/brake system manufactured by the defendant Shimano, according to this expert. The plaintiff’s expert also explained that the wire brake cable will fail if the pulley is too small because every time the break is used it bends and unbends the wire over the pulley. The plaintiff’s bicycle p 7 3 industry expert opined that the bicycle was also defective in that it lacked a mechanism to prevent the cable from entangling in the front tire in case of a break and lacked adequate warnings. The plaintiff’s rehabilitation expert testified that the plaintiff has been rendered a C-5 quadriplegic with some limited arm use and no use of his legs. The plaintiff is permanently disabled, has lost all sensation below the chest and is incontinent, according to his physician. The plaintiff’s physician also testified that the plaintiff will require an average of one hospitalization per year for the remainder of his normal life expectancy. In addition, the plaintiff suffers from

Re: [RBW] What if the answer is knobbies on the QB?
Untrue. It's not safe to ride with cantilever brakes with "traditional" style ^ cables and knobbies w/o fenders. Shimano created a new style of hanger cable to fix that problem when it surfaced decades ago.

Re: [RBW] What if the answer is knobbies on the QB?
I'd be more worried about knobbies + fenders + off road debris. If something gets stuck in the fender, it could stop the wheel very fast.

Knobbies and canti's not "safe" ? Sure for those that promoted v-brakes and slick tires and "protection" devices I suppose since their sales depended upon this myth... but for the countless rest of us it is not and never was. Safety and peril are 2 sides of the same coin, dependent on each other and satisfying nothing. For Deacon Patrick, It seems to me a custom frame of some sort would be your "answer". That way it could be designed just as you needed, instead of trying to make bike after bike work by compromise. By the time you add up all the time and money spent on compromises you can have a custom. But with compromises all you have ever have is compromised from the very start and won't be anything else. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] What if the answer is knobbies on the QB?
It's the straddle cable falling into the knobs fear. Someone used to sell -- in fact, perhaps Rivendell sold -- a little arm that bolted to the crown and projected forward between straddle wire and tire; I had one myself, and may even have installed it on one bike. But, as Eamon says, cantis and knobs came together on just about every mountain bike before the invention of the V brake, and this was simply taken for granted.

I was as able to fit the wide Nokian W106 studded tires on my Quickbeam with SKS fenders. It was a tight fit but worked ok. Slush build up was an issue.

The idea of narrower studded tires got me thinking: what if the answer to my winter riding quandary is the Quickbeam (ss, solves drive train in weather issues, plus, it has fenders) is Compasses supple knobbies, the Steilacoom TC. Perhaps this winter I will try the narrow tire (now with knobbies) approach to winter, at least on those freeze the drive train days. Grin.
