EB14: Fulcrum Gets Carbon Tubeless, Tubular Mountain Bike Wheels, Plus Alloy Models & Stealth Road

2015-Fulcrum-Red-Carbon-tubeless-mountain-bike-wheels

While sister brand Campagnolo unleashed new top level carbon clinchers for the road, Fulcrum added them for the mountain. Along with carbon tubulars and new alloy clinchers, too. These come just one month after they introduced their latest top level alloy racing wheelset, the Red Power HP, and about two months after we spotted prototypes being tested by Merida Multivan. For road, they added a blacked out Nite version of their Racing Zero alloy wheels that promises better braking performance.

The Red Carbon tubeless ready clinchers will be available in both 27.5″ and 29″ sizes with these subtle gray-on-black graphics. The rim is full carbon, and the hubs get carbon shells with alloy flanges built around a cup-and-cone bearing system. It’s all tied together with bladed, double butted stainless steel straight pull spokes. Weights are impressively light at just 1,356g for the 29er and 1,288g for 27.5″, thanks in part to a titanium freehub body.

EB14: Open Cycle’s 15.12lb Race-Ready Hardtail Mountain Bike

Open Cycle 1.0 ultra lightweight hardtail mountain bike

How do you take one of the lightest complete bikes and make it even lighter? Add a Lauf Fork and THM Clavicula cranks, of course.

Following frame tweaks and a production shift to Germany announced earlier this year, the chassis comes in at under 800g for a size Large. Until now, the lightest complete build we’ve seen from them was a 16.2lb bike with Di2 parts. Now, they’ve pushed more than a pound lighter by running XX1 on one of the lightest cranksets and forks on the market.

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.

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…

Factory Tour: Seattle Based Hampsten Cycles Builds Steel, Ti, And Now Carbon

hampsten cycles fabrication shop

While Oregon seems to be mecca for custom frame building, there is no shortage of exemplary builders located throughout out the North West. For those in Seattle, one of the best options is Hampsten Cycles. Over the fifteen years they’ve been in business, their frame construction has been subcontracted out to various industry luminaries including Kent Eriksen, Parlee, and Moots, but they’ve recently brought everything under one roof.

Today, all Hampsten Cycle frames are built in house by Max Kullaway, who has welded thousands of frames for high profile builders including Merlin and Seven Cycles, and fabricates his own bikes under the name 333Fab

During a recent trip through the PNW, I stopped by their small workshop to get a closer look at some of the beautiful bikes Hamspten cycles produces from a two car garage in a quiet residential neighborhood in Northern Seattle.

IB14: Sarma Doubles Up on Carbon 29+, Introduces new Aluminum Vortex Fat Bike

0912_6502 copy

While the majority of fat bike companies are based in North America, Sarma Bikes continues to put out some impressive equipment by way of Siberia, Russia. Now being imported to the U.S. by a new distributor, the products should be easier than ever to get a hold of which is a good thing – Sarma is blowing up. After introducing the first ever double wall carbon 100mm rim, Sarma now has their sights set on 29+ and has a new Naran carbon rim to prove it.

Technically Kuroshiro is also offering a carbon 29+ rim with a box section, though as far as a true double wall carbon rim the Naran is it. Available as an individual rim, Sarma is also offering two 29+ Shaman builds complete with a Bluto suspension fork. Carbon may be the most buzz worthy, but Sarma also has a new option for the more budget conscious with their new aluminum Vortex fat bike frame. Details next…

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…

IB14: TwinSix Standard Bicycle Collection Debuts – 29er, Cyclocross, Rando & Fat Bikes

2015-TwinSix-Standard-29er-mountain-bike03

After years of frame collaborations with Raleigh, Handsome and others, TwinSix let loose in early August that they were working on a collection of bicycles, giving us a detailed look at the Standard Fat titanium fat bike. That one’s shown at top, and hit that link for the full details.

Sitting in front of it is the Standard 29, their Reynolds 853 steel hardtail. It’s suspension corrected for a 100mm fork to have a 70.5º head angle. Chainstays are reasonably short (17.32″ / 440mm) while leaving room for a 29×2.35 tire. Ride the metal past the break for more details, pics and models…
