EB14: Jagwire Warms up to Disc Brakes w/ New Finned Cooling Rotors

jagwire elite cr1 finned brake rotor

Jagwire is jumping straight into the premium category with their new Elite CR1 vented 3-piece brake rotor.

The three piece design pairs a stainless steel braking surface with stamped aluminum fins pinned to them. Those sit on a forged alloy spider, which helps keep the whole thing very stiff.

They’ve benchmarked them against Shimano’s IceTech rotors, and they say performance is equivalent, even being a hair better, for the first 100 seconds they’re the same. And how often are you braking for 100 seconds? Performance, in their tests, refers to heat management. Theirs stayed a bit cooler during the first minute of braking…

Giro & Bell Partner With MIPS & IceDot, Plus Bell Launches New Multi Impact Rated DJ Helmets

 

Giro MIPS Diagram

If you’re unfamiliar with the technology, MIPS is the biggest buzzword in helmet safety today. The acronym stands for Multi-directional Impact Protection System, and is a technology that seeks to reduce the damage from angled impacts. It works by using a liner inside the helmet as a low friction slip plane, which allow the helmet to rotate slightly in a crash and helps absorb rotational energy.

Both Giro and Bell will be launching helmets with the technology that span their commuter, road, and mountain bike line ups.

At trade shows everyone seems to ask the same question – have you seen anything cool?

Schwalbe seems to have no such trouble thanks to their game changing tire technology – Procore.

After a few good teases, the production version of the system was unveiled tonight at the Dornier Museum Friedrichshafen which happens to be a fitting shrine to German engineering.

2015-Felt-Z2-Disc-brake-road-bike

Felt released the rest of their 2015 road bikes at the beginning of August, but they saved one for Eurobike. With the burgeoning gravel racing market, the F1 PR looked pretty good, except it doesn’t have the other current road buzz word: Disc brakes. Ender the new Z-series Disc. It’s a new version of their popular Z-series road bikes that adds disc brakes and a bit more tire clearance.

The top model, shown here, gets Shimano hydraulic disc brakes, Ultegra Di2, the new Mavic Ksyrium Disc (which we’ll have more info on this week!) wheels and FSA SL-K crankset.

Below that is the Z4 with SRAM hydros with 160mm rotors and Rival group, Mavic Aksium wheels and Zipp cockpit. Finally, there’s the Z75 alloy model with a Shimano non-series/105 mix with TRP Spyre mechanical disc brake calipers running 160/140 rotors.

Spy Shot: Prototype Chris King Lefty Hubs

Chris King Lefty Prototype Hub

Spotted on professional cyclist Ryan Trebons twitter feed, this fancy new Lefty hub from Chris King is currently not in their catalog. The company originally let slip they were working on a conversion kit for their oversized mountain bike hubs last year at Sea Otter, but had not set an official release date. From what we were told then, the hub will utilize their existing non-drive clamp fitting, but have all new axle parts.

We’ll post more details as we get them…

Since the introduction of the RockShox RS-1 there has been a discussion about the availability of compatible front hubs. Due to the Predictive Steering, the forks require a special hub design that initially was very limited in manufacturers.

While there has been some talk of SRAM approved hub designs, other manufacturers like American Classic have taken it upon themselves to design their own hub for the new fork. Technically still a prototype, we get a sneak peek at the new hub next…

EB14: Quarq XX1 MTB Power Meter Gets Official, Teases New Features for All Models

2015 Quarq XX1 crankset power meter

Quarq has officially launched their XX1 power meter spider for all SRAM 1x mountain bike cranksets. It’s available as a chassis, built onto an XX1 level crank arm using a new mounting interface and other new features.

It adds in “multipoint, active temperature compensation” that’s pulling from 10,000 data points to calibrate it as it’s cycled from 0° to 130° F. That provides a baseline setting for temps within that range. So, outta the box it knows what the calibration should be for any temperature you’re likely to ride in, staying accurate for the whole ride, season to season.

Power through for more new features that’ll carry over to all their power meters…

They have divided the product line into three distinct models, which are versatile enough to encompass several dissimilar but related cycling disciplines – everything from gravel, CX, to XC and trail.
