EB14: Xentis Brings Full Carbon Wheels to 27.5″ with New Size for Kappa2

Xentis Kappa2 CC 275  (2)

Mag wheels were big back in the day. Now made from carbon rather than plastic, the one piece wheels aren’t quite as popular but that hasn’t kept Xentis from building on their Kappa2 line. Originally just for 26″ frames, the Austrian carbon company has upped the size to accommodate the new crop of middle sized wheels. Xentis calls the Kappa2 CC a super durable wheel that is still light enough for marathon or XC use. It’s unknown whether these wheels will ever make it into the U.S., but we have more details after the jump…

EB14: Novatec’s Factor Carbon Mountain Bike Wheels Launch For Real – More Sizes, Too!

2015-Novatec-Factor-carbon-fiber-mountain-bike-wheels

Introduced last year at Interbike, Novatec’s premium Factor lineup showed all three diameters in the new carbon fiber rimmed wheels, but word is only the 26″ model made it into circulation. And only in limited quantities.

Now, the brand has made a few refinements to the rims’ shape, introduced a more XC-oriented 1-series, and should have everything ready to ship. The wider 3-series has all three diameters and a rim width of 23mm inside, 30mm outside at the top of the rim. The 1-series gets a bit skinnier at 21mm inside/28mm outside and only has the 27.5″ and 29er sizes.

Beyond having a carbon rim, the other main upgrade from the Novatec lineup is a 3º engagement in the rear hub. It pairs a 60-tooth engagement ring with six double-tooth pawls. Three pawls are engaged at any time, and the other three are partially engaged. Each pawl has two teeth on it, so there are technically six points of engagement at any time.

IB14: Onza Goes Wide for Enduro, Shows Different Internal Casing Profiles

2015-Onza-Citius-275x24-freeride-enduro-mountain-bike-tire

After loving several of Onza’s tires at the Cane Creek Double Barrel Inline launch, we’ve been paying closer attention to the brand. They, like virtually everyone else, are bolstering their offerings for both 27.5″ wheels and the enduro discipline.

For the latter, their new EDC enduro casing uses a folding Kevlar bead and a thin butyl rubber layer from the bead all the way up the sidewall to the start of the knobs. Their DH tires use a thicker, shorter butyl section to protect the rim, but these use a thinner, taller section to provide better sidewall protection while keeping the tire more supple and much lighter.

The Ibex (2.4 in all three wheel sizes, plus 29×2.25) and the Citius (27.5×2.4) will get the new casing. The Citius are shown above, the Ibex is below along with a cutaway of the different sidewalls…

Nox Composites Goes Hookless, Drops Rim Weights & Intros New Models

Nox-Composites-Skyline-29er-carbon-rim-mountain-bike-wheel

Nox Composites has revamped their rim lineup, changing to hookless beads across the entire line and introducing two new models. They’re also expanding their hub and spoke build options, helping anyone find the right wheels for their budget or desires.

Cofounder Brad Stinson told us the hookless design came about because they wanted to reduce weak spots while still being able to build the rims as light as possible. Their design’s IP revolves around the seam placement, namely the seams between mold plates that press the carbon into shape. Because of the way the molds often go together, a lot of rims have a seam right at the top of the bead, which is a prime spot for delamination to occur. Others start out with a thicker “hookless’ bead then machine out the hook. With ours, we’re able to put the seam from the molds far away from the top of the rim wall, like under where the rim tape goes so it’s protected from rock strikes or other things hitting or rubbing on it. They’re calling it Rockguard HL, named because they surmise that most rim failures occur because of rocks striking a rim’s seam and starting the destructive delamination process.

That, plus new layup mix of materials and weaves, allowed them to develop a 345g Xc rim called Skyline with no compromises…

IB14: Jamis Renegade Adventure Road Bike Breaks Outta Production, Plus New Women’s 650B Mountain Bikes!

2015 Jamis Renegade adventsure gravel road bike

Jamis’ Renegade adventure road bike goes beyond a single classification. It’s a fondo bike, endurance bike, gravel bike and commuter road bike all at once. It’s also looking like quite a high performance bike when called upon to hustle, too. Like when Tyler Wren took 3rd place in this year’s Crusher in the Tushars.

They introduced it this summer just before that event along with a healthy dose of info, but at Interbike we put it on the scale and got a few more details about production spec and builds. We’ve got plenty of pics and notes to share, and their new product video really puts it all into motion…

IB14: Swobo Expands Bicycle Collection – New Gravel/Adventure, Mountain & Fat Bikes

2015 Swobo scofflaw steel cyclocross bike

Back in January, Swobo added step-through versions of their existing Fillmore and Novak city bikes. They followed up with the launch of an all new youth line called Farrier. Now, they’ve more than doubled the adult line with four new models covering a range of terrains.

If you’re looking for a do-it-all road bike that’s ready for gravel rides, cyclocross races and backroad adventures, the Scofflaw is the ticket. It’s built on a Reynolds 531 steel frame with tapered carbon fork and room for 700x42c tires. It comes complete as a singlespeed bike, making use of the Tange sliding dropouts, but will include extra dropouts with a derailleur mount if you wanna add gears later.

That drivetrain versatility is built into some of the other bikes, too, and all are worth a look…

Must Watch: The Rampage Podium Winning Helmet Cam Roundup

Due to rain delays, the Redbull Rampage finals were postponed till Monday, which meant productivity for mountain bikers was at an all time low during the live stream of the event. For those of you who were actually diligently working, we’ve rounded up the POV footage of three of the best runs (and will continue to update with more as Redbull uploads them).

Up first is Brett Rheeder. This Canadian phenom was oh so close to stealing the show from Brandon Semenuk at the Crankworx slopestyle event earlier this year, and came out charging in Virgin, Utah. His combination of tech, big air, and huge tricks was breathtaking, yet only good enough for 5th place.

Drop past the break to see what previous winner Cam Zink and this years champ threw down. READ MORE ->

IB14: Michelin Sizes Up with 28mm Pro 4 Endurance Road Bike Tires

Michelin Pro 4 28mm  (1)

Road tires are at an interesting state of development. Many riders are starting to trend towards wider rubber even on the road, but then the definition of road riding is evolving. Thanks to the growing popularity of “gravel” ride, races that include dirt roads, and more people taking the path less traveled, tires are often being subjected to new abuse. Already an ideal size for many gravel or dirt adventures, the 28mm tire has become a favorite since it will fit in many standard road frames and some caliper brakes adding a bit of additional capability.

In developing their new Pro 4 Endurance tire, Michelin wanted to offer a 28mm tread but also a durable tire that would keep flats at bay. To that regard the tire features a reinforcing layer that claims a 40% increase in puncture protection compared to the competition while a dual compound rubber provides long wear and excellent cornering grip.

IB14: Jeff Jones Goes Big with Jones Plus 29+ Model, New Steel Spaceframe, Headset, more

Jeff Jones 29+ 275+ adventure bikes  (6)

The latest creation to come out of the Jeff Jones workshop is a 29+, but Jeff is very quick to point out that this isn’t your average bike with big tires. Jeff mentioned that the inspiration for the bike came while riding some super heavy cargo bikes in Asia that still handled well in spite of their exceptionally long wheelbase. While the Jones Plus also has a long wheel base, the fork and frame have been designed together to provide a super comfortable and stable ride that retains its quick handling.

Jeff also had the newest version of the Jones steel Spaceframe and Truss Fork on hand with 27.5+ wheels which will be an option, but he personally still prefers the larger 29+ wheels and tires. All together the new wheel options mean there are 4 different tire configurations possible with Jones frames making them even more versatile than ever before…
