EB14: Kuroshiro Puts the Salsa Bucksaw and Niner ROS9 Plus On a Carbon Diet

Kuroshiro light weight fat bikes 29+ carbon wheels (1)

If you have been paying attention to the plus-size carbon wheel market, you know that Kuroshiro has been rewriting the rules when it comes to fat bike wheels. The super light carbon hoops are designed to run tubeless without rim tape and owe much of their strength and stiffness to their unique SPline design with uses a continuous raised center carbon ridge.

Recently, the company introduced a slimmed down version of their fat bike rims to cater to the 29+ crowd. Using a similar technology but with a completely boxed center channel, the wheels are a simple 1 step weight loss program for your bike – as long as you have the cash. To illustrate the weight savings provided by their wheels, Kuroshiro swapped out the wheelsets on some common, mostly stock fat bike and 29+ models to show what is possible.

Light weight fatties ahead…

EB14: Mondraker Makes the Wheels Bigger & the Mountain Bikes More Aggressive

2015-Mondraker-Crafty-29er-full-suspension-trail-mountain-bike

Mondraker introduced the new Foxy Carbon this summer, essentially claiming the 140mm travel, 27.5″ wheel mountain bike was a quiver of one. But, supposing you like larger wheels, the new Crafty 29er takes the concept up a notch with bigger diameter hoops.

It keeps their Zero suspension design, which floats the shock between two moving links. The rear triangle is one piece to keep it stiff. It also gets their Forward Geometry, putting a longer top tube behind a very short stem. Other than wheels and necessary frame sizing tweaks, the only functional change was a slight drop in rear wheel travel to 130mm. The front end keeps the longer 140mm fork. There’s even an XR version that gets a 150mm Pike.

Other bikes grow to 27.5″ from 26″, spec gets updated and a new fat bike makes an appearance below…

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: German:A Unveils Inverted Fat Bike Fork, Integrated e-Bike Display & More

German:A Trace inverted fat bike suspension fork

Building off their existing inverted fork designs, the new German:A Flame fork takes the internals are from their 130mm 26″ fork, then limits the travel to 100mm to allow proper tire clearance at the crown under full compression.

It’s built around a 142mm front hub and has clearance for 26×4.0 tire. Up top is their travel adjust button, found on all their forks, which uses a dual air chamber with a valve in between. Simply put your weight on the fork and push the button and it’ll drop into its travel. Stop it anywhere you want and release the button and it’ll stay there, working as normal in the reduced travel mode.

But that’s only part of the interesting tech they had on display…

EB14: TRP Updates HYRD Brake Calipers, Adds Camo Spykes & More

trp-hyrd-caliper-pro-shotTRP’s HYRD calipers, which are their mechanical-to-hydraulic brakes that work with any standard drop bar lever, received a rather quiet update at the beginning of the year.

All of the changes were aimed at improving long term performance and keep users from fiddling with the parts that could cause failure. Inside, they swapped the gasket’s material the reservoir so it is more pliable. This reduces the likelihood of the system creating a vacuum since it won’t pull as hard against the fluid when levels decline slightly as pads wear. In other words, it lets the system more easily compensate for pad wear.

They increased reservoir volume to hold more oil, which should help with heat buildup. A steel ring was added around the pistons to help them slide in and out easier. Before, it was solid Bakelite, which does a great job of insulating against heat, but wasn’t as smooth, so now it’s just used in the center of the piston.

When we reviewed the original HYRD brakes, one of the tweaks we made to improve pad contact speed and power was to dial in the piston rod. Unfortunately, TRP frowns upon this and for good reason: It can cause the system to remain closed or open depending on which way you turn the bolt. Either way, it could mean brakes that don’t work.

EB14: Ryde Goes Wide, Steps Out from Behind OEM Curtain w/ New Rims for All

Ryde-trace-ultra-wide-mountain-bike-rims01

For us, Ryde’s been primarily known as the company that always had a very light scandium road bike rim luring us into their booth. The rep said they’ve mainly been an OE manufacturer for others thus far, but now they’re looking to bring rims to market under their own brand name.

To start, they’ve created some impressively wide mountain bike rims for both XC-to-enduro and lighter weight race-oriented pursuits, plus a fairly standard road bike rim and some prototype fat bike models. The Trace, above, is the XC/Trail/Enduro model and will be available in all three wheel sizes in three different widths: 21, 25 and 29 millimeters. Those measurements are internal widths…

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: Vredestein Gets a Muddy Bobcat Mountain Bike Tire, Plus All Weather Road Options

Vredestein-bobcat-enduro-trail-mountain-bike-tire01

Just as the Bobcat is an adaptable predator covering terrain from Canada down to Mexico, Vredestein’s new Bobcat all-round, all-conditions tire aims to attack anything it rolls across.

Likewise, it covers all three wheel sizes, from 26″ to 27.5″ to 29er, all in a 2.35 widths and with tube and tubeless ready versions. They use a 120tpi casing and respectable weights considering the intended usage. Prowl for details below…

EB14: Campagnolo Bora Wheels Gain Clincher Options

2015 Campagnolo Bora Ultra and Bora One carbon clincher road bike wheels specs and weights

This summer, Campagnolo’s top level Bora wheels were redesigned to be wider, lighter and have better braking performance. But they were still tubular only, as has always been the case for that model.

But even Campy admits not every top rider wants to deal with glue or the risk of being stranded (or carrying the spare and paraphernalia to use it). So, they’ve finally introduced a clincher version with the same options. Choose from 35mm or 50mm depths and Ultra or One trim levels. Both use a 24.2mm wide (UPDATE: 17.4mm internal width) rim with the 3Diamant braking surface they say offers equal stopping performance to alloy rims. Wheelset weights are around 200g more than the tubulars, and you can catch all the tech and closeups below…
