EB14: Birzman Reinvents the Pump Head (Again) with the new Snap-It Apogee

Birzman Snap It apogee new pumps tools (20)

Birzman first gained a lot of attention when they introduced their Snap-It pump head at a time when many screw on heads were causing presta valves to blow their tops. While the Snap-It was certainly good, it wasn’t perfect as we found with certain valve styles. Looking to remedy that situation, Birzman has introduced the latest version of the Snap-It, the Apogee. Not only does the new head make it even easier to inflate presta valves, it also requires less work to inflate schrader valves in what looks like a winning combination for pumps.

Snap into the details next…


EB14: American Classic Carbonator Wheels Get Official, Sprint 350 Gets Upgraded

American Classic Carbona carbon wheels sprint 340 tubeless (2)

Spotted as just a prototype in Taipei, American Classic’s Carbon mountain bike wheels made their official debut in Germany. Called the Carbonators, the wheels are built with fairly wide rim profiles to provide excellent handling characteristics while still remaining light enough for cross country use. Available in 27.5 and 29″ diameters, the wheels will offer tubeless compatibility along with multiple hub configurations all for an impressively low price….


EB14: Connex Diamond Shape Chains Get Extreme Shaping for Better Shifting

Connex Diamond Shape high end bicycle chains

Connex has a new chain design called Diamond Shape, which radically chamfers the outer and inner links and their interface with the rollers.

They’re compatible with SRAM, Shimano and Campagnolo because they basically blend the chamfers and shapes used on those brands’ chains. All of them. And then they add a little more just to be safe. The result is a more angular leading and trailing edge at all points on the chain, helping it scoot from one cog to the next.

Detail photos and diagrams below that better compare the old with the new…


EB14: Projekt MRSC – Electronically Controlled Full-suspension Road Prototype from Canyon


In an effort to combat rider fatigue from road surface vibration and ensure all of the cyclist’s energy is put to forward motion, Germany’s Canyon bikes have introduced a smart full-suspension road bike prototype at Eurobike. The concept bike dubbed Projekt MRSC Connected ( for Magneto-Rheological Suspension Control) is a move in the direction to highlight a design focus on comfort, as lightness and stiffness have continue to progress almost exclusively at the high-end. Canyon feels strongly that more comfort means higher performance, and has incorporated their own VCLS Technology (Vertical Comfort, Lateral Stiffness) into their frames for several years. The Projekt MRSC is a next iteration in expanding this tech.

Canyon’s engineering team sees constant road vibration as the next biggest cause of rider fatigue beyond pedaling effort. As the back and leg muscles undergo stress to counteract road impacts and stabilize the bike, rider comfort decreases and with it endurance and speed. The vibration also breaks the bike’s contact with the road and its intended path, consuming unnecessary energy.The MRSC system proposed an active bike frameset to enhance comfort and handling, with less energy input.

Join us after the break for a detailed look at the bike, how it works, and how it stays connected…


EB14: Kenda Juggernaut Fat Bike Tire, Honey Badger DH & Kountach Endurance Road Get Official


We’ve seen quite a bit of these “new” tires from Kenda by now, with the mountain bike tires popping up at Taipei Bike show in March and Sea Otter in April. And the Kountach Endurance road tire was shown in great detail at Interbike 2013. But, now, we have full production details for all and weights for most.

Heretofore, the Juggernaut had only really been seen in Sport trim, which, uh, sports a wire bead. Eurobike brought out mention of a Pro version with folding bead, too. While the tread resembles some of their standard mountain bike tires, it’s actually inspired by Kenda’s Millville 2 motocross tire. Tread blocks are tied together to make them a bit sturdier while also providing a bit of a paddle effect for mud and snow. They’ll come in 26×4.0 and 26×4.5 in both versions. The only claimed weight so far is for the Sport 4.0 at 1,360g (+/-50g).

Specialized Releases Limited Edition Steel Allez

2015 Limited Edition Steel Specialized Allez Road Bike Frame_10

The Big S is turning 40 and to celebrate, they’re doing what they do best, building a beautiful limited edition frame. This time, the company has turned their attention to the Allez.

Working with Mark DiNucci, one of the original Specialized frame builders, they’ve reexamined every tube, lug, and braze-on to create a totally modern steel frame. Starting September 8th, the company will auction off 74 frames, which were built in the same factory as the original. Once they’re sold, Specialized will never sell or produce the replica frameset again.

As an added bonus, 100% of the proceeds from the frame sales will go to World Bicycle Relief. Head past the break for more photos and the full press release.


EB14: New Quarq Elsa RS Power Meters for Shimano 4-Arm Hollowglide Chainrings

Quarq Dura-Ace DA9000 power meter crankset

Quarq has added another option to their crank spider based power meter offerings. Already stocking units for a variety of SRAM cranksets (including the new XX1 mountain bike version) Specialized and Cannondale, now you can add Dura-Ace DA9000 to the mix.

The unit gets all the new technology introduced with the XX1 model, including the multipoint temperature calibration to keep it accurate from 0º to 130º F (-17C to 54C) and accelerometer based cadence measurements. Those combine with their usual features – OmniCal (maintains accuracy regardless of chainring selection) and Power Balance (captures left and right side strokes independently).

You will have to swap to their ExoGram hollow carbon crank arm, but if you’ve already got the Shimano crankset, then at least you won’t have to buy new chainrings. Yes, SRM has offered 11-speed DA power meter cranks since last fall with a version of Shimano’s crank to maintain the aesthetic, but they’re double the price…


EB14: All New Cannondale Slice Triathlon Bike Debuts, Plus CAAD10 Track Bike & Budget Road Racer

2015 Cannondale Slice Black Inc triathlon bike

The all new Cannondale Slice triathlon bike will formally debut at Ironman World Championships Kona in October, but we’ve got a first look at the top model, the Slice Black Inc.

Goals were to reduce weight as much as possible, add aero efficiency and make it more comfortable. Compared to the outgoing model, they don’t have final wind tunnel data but they’re saying it’s significantly improved. That was done by making the frontal profile narrower, reshaping the fork legs, and smoothing the fork crown to downtube transition.

Those aero changes were the obvious ones. It’s the other little tweaks that make it unique -and UCI illegal- along with the impressive frame weight…


EB14: THM’s New Clavicula SE Crankset Drops More Weight


THM debuted the newest iteration of their superlight carbon fiber crankset at Eurobike – the Clavicula Sine Exceptione, following on their latin naming this one sticks with the clavicle/collar bone name with a ‘without exception‘ subtitle. Certainly nothing was spared in this design either. The entire crank is made of carbon fiber with only the pedal inserts and clamping bolt being alloys. The big feature to note here is that carbon fiber spindle with THM’s standard spline interface molded in, and the new-in-carbon clamping surface on the lefthand crank arm. Read on to see how much weight they saved and where they are going next…
