Updated – EB14: Cervelo Ups the Aero Road Ante Again with a New S5, plus Updated RCA

After almost universal accolades from the cycling media for the previous generation of the S5 as possibly the fastest road bike on the market, including our own, instead of taking it as a compliment, Cervélo took it as a challenge to make the bike even faster. What resulted is a new bike that chops another 21.3 watts off from the last S5 VWD.

At the same time for the RCA, Cervélo went back to the drawing board to see how they could make their handmade super bike an even better all-arounder, and where they could make measurable weight gains.

Read on for full details on the S5 and the lowdown on the new RCA… READ MORE ->

EB14: All-New Parlee Altum w/ Disc & Rim Brake Models, Plus Lower Price ESX Aero Road Bike

Parlee Altum road bike with disc brakes or rim brakes

Parlee launched one completely new model, with three versions, at Eurobike, plus a more budget friendly edition of their ESX aero road bike.

The Altum, shown above in it’s top form with founder and designer Bob Parlee, replaces the stock Z5 series of bikes. Sitting at the base of Parlee’s Z-series hierarchy, the Z5 was their semi-customizeable stock frame that provided a lightweight, fantastic riding road bike with Parlee’s signature comfort and performance. The Altum looks to improve on every aspect of that while also adding a much more affordable disc brake option to the line up.

Three version will be offered: The Altum is the top of the range and replaces the Z5 SLi. The Altum R gets a slightly heavier, lower level carbon and replaces the Z5i. The Altum Disc gets the same geometry as the rim brake models but is disc specific with convertible rear dropouts. All of them get a new Parlee fork, and the top model gets their new Parlee carbon seatpost.

Ride on for the complete tech breakdown, actual weight, and a look at one amazing custom paint job!


EB14: Reynolds Carbon Road Bike Wheels Go Tubeless, New Disc Brake Options

reynolds assault strike performance carbon wheels go tubeless with more disc brake options

Reynolds’ Attack, Assault SLG and Strike SLG Performance road carbon clinchers all become tubeless ready for 2015, and the Attack becomes available in a disc brake specific option, too. The 46 Aero also gets a disc brake option, and three Aero (46, 58 and 72) wheelsets all get tubular rim options. 

Weights for the Performance line stays the same with the switch to tubeless compatibility, coming in at 1365g, 1515g and 1635g. Depths are 29, 41 and 62 millimeters respectively, and all are rated for anything from road to gravel to cyclocross.

To go tubeless the bead hook and channel had to change, and designer and aero guru Paul Lew explains…

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…


EB14: New Pro-level Noah SL Aero Road Bike From Ridley


With feedback from their Pro-Tour sponsored Lotto-Belisol team, Ridley has developed an evolution of their Noah FAST aero bike concept into the professional-level Noah SL. The Noah SL fits in between the 2 bike the pro-team picks from, the Helium and Noah Fast, pulling benefits from each to create a bike to keep weight low, while still giving riders the aero advantages they’ve come to demand for the fast and bunch sprint races.

Come past the cut for detail on the development and the tech on the new bike.


Felt Adds Z-Series Disc Brake Road Bike, Abides with Dude Fat 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.

Check some frame detail photos below, then chill with the Dude…


New 1050g Easton E100 Full Carbon Tubulars Introduce Tuned, Tensioned Carbon Spokes

2015 Easton E100 ultralight 1050g full carbon tubular road bike wheels

Easton has brought boutique levels of carbon to a mainstream wheelset with the new E100 to create 1050g tubulars that can easily be repaired.

Nothing about the E100s was pulled from Easton’s current parts bins. Instead, they spent more than five years developing all new technologies and designs to create something they say is not just incredibly lightweight but stiffer than other full carbon spoked wheels. And it can be repaired far easier than other completely carbon wheels.

The rims are a new “Fantom” shape, and the hubs get a full carbon body with two donuts on either end holding the spokes for that side of the wheel. Those spokes, which are indeed full carbon fiber yet thinner than what we’ve seen from others like Lightweight and Mavic, are then hand tensioned to properly build each wheel for the best performance.

Last week’s USA Pro Cycling Challenge may be over, but the product news continues. SRM chose the Colorado stage race as the venue for their public release of the all new PowerControl PC8. After years of listening to the pros and weekend-warriors alike, after nearly two years of development and research, the production model is finally being released. Power past the break for details, pics, and some rumors on future SRM developments…


Alchemist Unveils Zirconium Disc Brake Road Bike Wheels – Light, Stiff & Asymmetrically Aerodynamic


Alchemist has shown us some pretty wild looking wheels for mountain bikes in the past, and now they’re applying their unique take to the road market with an astonishingly lightweight set of disc brake-only clinchers.

The new Zirconium wheels use an asymmetric rim profile to balance spoke tension evenly from side to side. The 2mm offset also improves dish, and reinforced spoke nipple beds increase strength, allowing them to use higher tension for a stiffer wheel. All that, and the high modulus carbon fiber rim weighs in at just 315 grams!

As usual, their hubs are a work of art, mixing carbon and alloy with their signature angles and flares on the spoke and disc flanges. What’s unusual are the aero claims…
