Argonaut tailors to discs and wide tires

Oregon-based Argonaut Cycles has updated its road disc frame to better accommodate 30mm and 32mm tires. Each custom-built road disc frame features molded carbon dropouts designed to work with Mavic’s Speed Release thru-axle. They’ve also redesigned the carbon lay-up throughout the frame to strengthen stress points specific to disc-equipped bikes. A “test flight” program in the San Francisco area allows potential customers to test the bike in any size before ordering one to their specifications.

Enve fights flats with M Series wheels


The first generation of Enve’s M Series hit the scene in 2014. Off-road riding has changed since then, so Enve changed too. The updated M Series encompasses four main categories: cross-country, trail, enduro, and downhill. Each category gets an expanded rim width in order to accommodate high-volume tires. The trail and enduro wheels have three different rim width options (25, 30, and 35 millimeters internal). Furthermore, Enve claims its hookless bead system (and incorporated rim strip on enduro and downhill wheels) virtually eliminate pinch-flats. The new hookless bead rims Should allow riders to run lower air pressure while protecting against impacts that normally cause pinch flats. The cross-country wheelset (M525) and enduro wheelsets (M630, 635, 640) start at $2,800. The enduro wheelsets (M730, 735, 735E) and downhill wheelset (M930) start at $2,900.

Low-friction battle: CeramicSpeed responds to Muc-Off

When Muc-Off released its new NanoTube chain, the company claimed the NanoTube was 10 watts more efficient than CeramicSpeed’s UFO chain. But  CeramicSpeed is fighting back with its own statement that says Muc-Off’s testing does not account for the “slacking effect,” which occurs when the chain “slacks” or slightly unloads as it snakes through the rear derailleur. Thus, CeramicSpeed contends Muc-Off’s claims are misleading. Which chain is faster? We have yet to see any independent testing on either chain, but more competition is always a good thing.

Bike shop compressor in your pocket?

MilKit inflates tubeless tires in seconds while out on the trail. The company’s first foray into the tubeless arena was a valve system that made refilling sealant quick and easy while allowing the tire to stay seated on the rim. The addition of the booster to MilKit’s arsenal means you’ll be able to reseal and reseat your tubeless tires anywhere. The mini-compressor can be charged with a normal tire pump. The booster recently met its crowdfunding goal and is ready to move forward with production.

Scott’s new kicks have sights set on the racecourse


Scott’s top-of-the-line carbon mountain and road shoes have gotten a makeover and Scott claims they have the best stiffness-to-weight ratio on the market. The new line includes two road models and two mountain bike models. For road, the lightweight RC SL has an eye on the racecourse, while the  RC Ultimate focuses more on all-day comfort and affordability. Scott partnered with Carbitex to create an upper that takes advantage of carbon’s high-tensile strength and low elongation properties into a flexible form. This allows the upper to be both lightweight and stiff, while still conforming to the foot. A Boa closure system helps limit foot movement within the shoe. The RC SL road version weighs 245 grams, while the RC Ultimate is 10 grams heavier.
