IB14: Nikola Reinvents the Pedal w/ Sliding Q-Factor to Boost Power, Efficiency

Nikola Zivo road bike pedal with position based dynamic Q-factor

Among the more interesting inventions to come out at Interbike was Nikola’s Zivo road bike pedals, which actively change the Q-factor throughout the pedal stroke’s rotation. Here’s the official introduction:

Coming to marketing in Fall 2014, Nikola is the first road pedal that produces power, efficiency, and comfort. Nikola Innovation, located in Cleveland, Ohio, has been in research developing the optimal performance pedal. Studying the motion of speed skaters and cyclists has been the foundation of this new technology called “Zivo” which has Serbian origination meaning “alive”. Nikola completed studies at the Human Performance Lab of Cleveland State University refining the Zivo technology producing peak power improvement of 7% in a 30 second Wingate tests and efficiency improvement of 2.1%. This new motion creates comfort with riders’ knees and hips with its patented Synchronized Q-factor generated by Zivo. Two versions will be offered, one in Titanium at $549, the second in Stainless for $339. Both pedals are using a standard 3-hole standard style cleat and compatible with any 9/16” crank-arm threading.

IB14: Rolf Prima Rolls Out Budget Carbon Road Wheels, Adds Wider 27.5″ Ralos CXC Mountain Bike Wheels

2015-Rolf-Prima-Ares-ES-budget-carbon-road-wheels

Rolf Prima knows their carbon wheels aren’t the cheapest on the market (they’re also not the most expensive), so they wanted to help more people get on their paired spoke design and excellent carbon rims.

The new Ares ES series wheels do that by lacing their same Ares carbon fiber rims as the top level models to standard hubs and higher spoke counts to drop the price by $650 per set. The new build is available on the Ares6 (60mm deep) and Ares4 (42mm deep), both 27mm at their widest. Inside width is 17mm at the bead.

The ES wheels go from 16/16 spoke counts to 16/20, but use the same bladed Sapim CX Speed spokes. Total weight gain is just 70g, but none of that’s at the rim save for four more nipples. Even their folks admit the ride quality is very, very similar, you’re just saving a lot of money…

Following last fall’s introduction of the GE1 enduro mountain bike grip, this year see the addition of the GE1 Slim. It came about after feedback from their World Cup racers that wanted a little better bar feel, to feel more connected to the bike.

It’s only marginally slimmer, but it’s noticeable. Price is $34.99 for either size, and the new slims are available in March 2015. Check the visual comparison and all the rest of their new gear after the break…

IB14: Enduro Bearings Adding threaded Pressfit Bottom Brackets, New Tools & More!

enduro bearings threaded pressfit bottom brackets

Enduro is finalizing their new PF30 and PF86/92 threaded bottom brackets, looking to solve two of the biggest problems with pressfit setups.

They’re still pressed into the frame, but the alloy shell is stiffer and once pressed in, you thread it together lightly to cinch it tight. That eliminates any play, which causes those annoying creaks and groans, and ensures proper alignment, which extends bearing life and reduces drag.

The smaller one uses a standard Shimano BB tool. The bigger one uses their own tool, which also has teh Shimano size on the other end. They’re not sure yet of the tool will be included, but they’ll try to make it cheap if not. They’re also considering making it work with the Rotor BB tool, but not sure if the thinner wall on their BB will work properly with only 12 indents.

Should be available end of September with pricing similar to their other bottom brackets.

IB14: Upstart Legion Launches w/ New Disc Brake Rotors, Lightweight Cable Housing

legion-javelin-D-Drive-two-piece-brake-rotor01

Shortly after Interbike 2013, Wayne Moore left Ashima after quite a few years of developing lightweight brake rotors and parts. Between then and now, he’s been busy revamping the design and launching new rotors under his own company, Legion.

Two models will be offered – a one-piece and two piece. The Javelin D-Drive two piece rotors use an alloy carrier with a 420 stainless steel that are machined to nest into each other. That locksteps their rotation so the pin joining them doesn’t need to handle a load. So, he’s able to use an alloy pin rather than steel, which helps pull heat away from the rotor faster. It’s a no-rivet operation, and the pin floats freely, held in place with a star lock washer that takes about 150kg of force to pull apart.

Moore says the design is also stiffer since the pieces are tucked into each other.

IB14: Selle Italia Goes Enduro, Plus New Road & Cyclocross Saddles

Selle Italia Butcher DH-Freeride and Nepal enduro mountain bike saddle

Selle Italia’s long been known for their very flat, generally very lightweight road bike saddles. For 2015, the line expands quite a bit, introducing some rather trick mountain bike saddles and a rounder profile road bike seat.

Above, the new Butcher gravity saddle has a handle cut out that’s not for comfort or improved blood flow “down there”. Instead, it’s for grabbing when you’re doing tricks off ramps, so it’s aimed squarely at the DH/DJ/BMX crowd.

It’s named after Butcher Ranch Trail in Downieville, CA. The shape is thought out more for when you’re not going to be seated a whole lot…like ripping downhill, jumping, etc. The wider nose makes it easier to steer with your thighs. It’s got a thick “crash pad” at the front for landing hard, and all the edges are soft and rounded for easily sliding on and off when maneuvering, but a grippy TPU ribbed section keeps you from slipping off unintentionally.

But, they know not everyone is pulling superman seat grabs, so there’s another purpose for the hole…
