We’ve been wowed repeatedly by OPEN’s releases, whether it’s their interpretation of what a gravel bike should be, or their definition of no-detail is too small, or simply how they seem to keep everything as classy as ever.
While everyone is busy launching new gravel rigs these days, OPEN goes a different direction: a road bike. The new Open MIN.D., which stands for Minimal Design, is one sleek machine highlighted by an integrated seattube designed for comfort.
Since it’s an OPEN, you can pretty much assume it will be light. At 870 grams painted in size medium along with a 335 gram uncut (!) disc fork, you bet ya we want one so so bad. Pre-order is open today, with frames shipping before July 20th.
When I was told a few weeks ago that Goodyear was making a comeback into the bicycle tire business, I had to look up what they meant by “comeback”.
To be perfectly honest, I didn’t even know that Goodyear wasn’t in the bicycle business. With companies like Continental, Michelin and Maxxis knee deep into bike tires, you’d think Goodyear, the third largest tire manufacturer in the world, would be in the game in some shape or form.
Well, they were. As a matter of fact, the Akron, Ohio-based Goodyear produced bicycle tires from the company’s founding in 1898 up until 1976.
So unlike Michael Jordan’s one year “retirement” from the NBA, or Johnny Manziel and Dave Chappelle, it’s been 42 years. But guess who’s back, back again? Goodyear is back. Tell a friend. Thank you Eminem for that sweet quote.
While Goodyear’s new lineup consists of nine tires, I am just going to focus on the road-going Eagle.
That’s right, the sole road tire in Goodyear’s lineup shares the same name as the company’s better known racing rubbers both previously seen in Formula One and currently seen in NASCAR… and most likely as OEM tires in some cars. In fact, Goodyear even used the same font to label “Eagle” on the sidewall. Okay, I get it. The Eagle has a deep, high-performance heritage.
And Goodyear was kind enough to send us a pair in 25c to play with before the launch.
Our test samples weigh 310 and 311 grams, just a tad over the claimed 300 grams for the 25C tire. Installation was pretty straight forward. I was told the Eagle is mountable with just a floor pump. I managed to get one of the two tires inflated with no sealant while the second tire needed just a tiny bit of sealant and compressed air from my Bontrager TLR Flash Charger. There wasn’t any overnight leakage, either. I did, however, injected some sealant into that one dry tire for extra insurance before my first outing.
My first ride using the tires was a 70-mile stroll following the weekend’s atmospheric river that caused some minor flooding, downed trees, and well, unpredictable road conditions that left me yearning for those disc brakes on the Focus Paralane I just sent back and I almost went to IKEA instead of riding. Not your ideal day to try out tires for the first time, or was it?
So off I went. Rolling down this 10% hill right outside of my house. The Eagle felt supple, dare I say even better than the Zipp Tangente RT25 I just came off of, or the stable Schwalbe Pro One 25s. Goodyear ostensibly didn’t include much info such as the tpi of the casing used, but did mentioned the inclusion of a Nylon-based fabric from bead to bead called R:Armor to combat against cuts on punctures.
Interestingly enough, the Eagle didn’t balloon as much as the other two tires, measuring at 25.55 and 26.17mm on our Bontrager Aeolus 3 TLR D3 rim-braked wheels. It’s definitely a welcoming tidbit if you don’t have a lot of tire clearance.
Not long after I navigated out across the slippery Golden Gate Bridge, I ran across this broken Jameson bottle in Sausalito. Last time I rode on wet road with glass, the glass won so I was waiting to hear the tell-tale hiss. Nope. Nothing. The show went on.
The more miles I rode on the Eagle, the more I trusted its capability. The proprietary silca-based Dynamic:Silica4 compound designed with a smooth center for low rolling resistance felt lively and comfortable at 90psi.
And that “best in class wet grip” Goodyear claims to have is pretty darn good too. The Eagle handled water graciously with its directional sipes on the edges and grooves to channel water from the center. I’d like to see the comparison chart, though.
It’s still too early to comment on the long-term durability of the Eagle but it’s looking pretty promising so far. So stay tuned for our long-term report. The Eagle retails for $70 in four widths: 25, 28, 30, and 32. The 30mm and 32mm will also come with a second version that includes reflective strip all the way around the tire.
Just when you thought things couldn’t get any lighter, Giro drops their new Prolight Techlace.
I first saw these prototype 150 gram super shoe at InterBike back in September and they were so freakishly light I honestly thought they were too good to be true. It sounded like a concept car that was more of an engineering exercise, never reaching the public. I was wrong.
At 150 grams per shoe, the new Prolight Techlace is about 25 grams lighter than the already feathery Empire SLX lace ups. And Giro was able to pull it off with some pretty unique engineering features.
Instead of the Easton EC90 SLX2 high-modulus carbon plates found in previous flagship models, the new outsole employs TeXtreme spread tow carbon fiber manufactured by Sweden’s Oxeons that uses flat tape versus the conventional yarn-shaped fibers. With such configuration, less resin is needed without losing any stiffness. The new TeXtreme outsole is said to be 22% lighter.
Moving upward, a custom monofilament fiber mesh is used as its upper. For better structure and increased durability, a thermoplastic polyurethane film by Japanese chemical giant Teijin is then strategically welded over the mesh to act as an exoskeleton, hence the seemingly two-tone looking upper.
For fasteners, the Prolight replaces the sole Boa dial found on the Factors and went with three Techlaces incorporating the comfort of shoelaces with the ease and on-the-fly adjustability of a conventional strap. The tried and trued SuperNatural adjustable insole remains, so it should have a similar fit to existing Giro shoe users.
The Prolight Techlace is available now for $400 in red, white and black. Sure, it’s a lot of dough for a pair of kicks, but these might just fit the bill if you’re looking for the absolute lightest without going full-on custom and they’re still cheaper than a pair of Yeezy Boost 350s.

And it’s a doozy.
You’ve seen spy shots, heard rumors, and might have even seen the official teaser (which more or less gave it away with the site aptly named www.duraace.com).
But yes, Shimano announced their new flagship road drivetrain group. The Dura-Ace R9100 series.
It’s still 11-speed driven with a metal chain, but the devil is in the detail, so let’s see what’s up with this grouppo.
At first glance, it’s easy to point out that the FC-R9100 crankset has an (even) bigger crankarms, a darker finish (instead of the two tone silver/black) than the previous generation, but there’s much more under the hood. Returning are the four-bolt, Hollowtech II crankarm construction, but the chainrings profile has been reworked with a slightly wider spacing to accommodate frames with disc brakes and shorter chainstays. It’s also seven grams lighter and thank goodness the spindle remained the same at 24mm that we’ve come to love, or loathe, depending on who you talk to.
Shimano is going to shake up the already crowded powermeter market a bit by offering their own power-measuring crankset, the FC-R9100-P. We haven’t seen much of the actual unit but we were told it’s a waterproof, dual-sided unit (powered by a single rechargeable battery) with an accuracy of +/- 2%. Communication will be done via your typical ANT+ and Bluetooth so you can use whatever head unit you have.
On the cable-actuated side, the front derailleur (FD-R9100) has been reworked so that gone is the long lever arm. The light shift action remains but the action is much more compact, and cable management is said to be much easier. Shimano has also integrated the tension adjuster right into the unit, so bye bye barrel adjuster. In the rear, the RD-R9100 borrowed the proven Shadow design from Shimano’s mountain bike derailleurs for a lower profile (no words on the possibility of any aero benefit – yet), direct mount capability, as well as better survivability in case of a crash (because shit happens). The hanger pulleys are also new, with a slightly longer toothing. To control the mechanical drivetrain, two models of STI levers will be offered. the ST-R9100 for standard caliper brakes and the ST-R9120 for hydraulic discs. The overall lever shapes remain more or less the same but with smaller detail upgrades such as textured hood tops (ala Campagnolo), and a claimed 14% shorter lever movement and 24% faster gear shift. It’s all about those marginal gains, dude.
Now that we’re done talking about the mechanical side of things, let’s talk about the Di2 system. Again, borrowing from the XTR Di2 MTB group, synchronized shifting is now available with the new Dura-Ace 9150 Di2 group. Besides the standard synchro mode where the computer shifts the front chainring while the user shifts the rear up and down the cassette, the new “semi” synchro model basically flips it the other way around where the user controls the front chain ring while the computer shifts the rear to keep a consistent cadence. Pretty novel concept, don’t you think? Hardware wise, the new rear derailleur (RD-R9150) will receive the shadow treatment similar to its mechanical brethren while the front derailleur (FD-R9150) remains largely the same.
Ultegra 6870 and Dura-Ace 9070 owners rejoice
New firmware is coming to your existing 11-speed Di2 groups this November so the synchro shift option is there if you so please.
Two more things on Di2
The lowly but oh so important cable junction box got a makeover and now there’s the option of having it integrated into compatible frames and handlebar ends for a cleaner appearance. Sure beats having a tiny black box at the bottom of your stem. While Shimano didn’t go full wireless like SRAM eTap, Shimano is releasing a wireless junction box, the EW-WU111, made to enable programming of the Di2 system from a tablet or phone (instead of a pc), as well as to those who want to transfer drivetrain data to computers for better visualization.
Unfortunately, the clutched Shadow Plus derailleur did not make it into the group.
As expected, Shimano didn’t stop making caliper brakes while launching their first Dura-Ace disc brake. And as if the previous Dura-Ace brake is not good enough, the new brake calipers have been updated for even more stopping power and clearance (thank you) for 28C tires. For the hydraulic brakes side of things, however, it’s completely new. The hydraulic caliper utilizes the Flat Mount mounting system for a smaller footprint while a wider pad clearance was made to further minimize rubbing. The most visually-striking part of the brake system, though, has got to be the new SM-RT900 Ice-Tech Freeza rotor. While the stainless steel braking surface remains, the rotor’s aluminum inner core now extends out as one continuous piece towards the center for better a 30% heat reduction. And similar to its predecessor, it will only be offer with Centerlock mount in 140mm and 160mm diameter, just big enough to double as a pizza cutter and throwing star (but don’t tell the UCI about that)
It’s the same CN-HG901-11 with the tool-free connecting link. Nothing new here.
Not much different other than the new 11-30 cassette combo. Let’s hope the dreaded cracked cassette syndrome is done and over with.
The overall design is the same as any other SPD-SL pedals but the new PD-R9100 pedals are now 24.5 grams lighter and now shipped with hollow cleat bolts (ProTip: Use good hex keys).
Well, that’s another department deserving of a separate post. But yes, there are redesigned hoops in various materials and forms
Price and availability
The full R9100 mechanical group will be available this September for $2029.92. The R9100/R9120 mechanical/hydro brake group will come at $2354.90; The R9150 Di2 group will $3046.85 whereas the R9150/R9170 Di2 with hydraulic brakes will cost the most at $3137.90. Yea, there’s actually four similar, but different groupsets this time around within the Dura-Ace family.

A custom aluminum frame is somewhat of a unicorn these days. Stroll down the aisles at NAHBS and it’s obvious that the dominant materials for frames are titanium, carbon, and steel. And those are all wonderful materials in their own right, but I have a soft spot for aluminum.
Well, Klein’s gone now (RIP), but my hope of finding a good aluminum bike is not.
The Low Down
Sure, you could go with a big name factory option like Cannondale’s CAAD 12 and Specialized’s Allez, but if you want custom aluminum hand-crafted by an expert, Andrew Low of LOW Bicycles is your guy.
Growing up with interests in model airplanes, guitars and cars, Andrew started building roll cages for off-road vehicles while pursuing his degree in fine arts in Colorado. After moving back to his native San Francisco in 2005, he got really into bikes, and eventually got the idea to make his own frame.
Years of researching tools, saving money, and welding practice finally yielded two frames by the summer of 2010. From there, Andrew “started to take those around town where bike messengers were hanging out.” The LOW frames were an instant hit, and that was the origin of LOW Bicycles.
Today, besides offering four different track models, LOW is dipping into the resurgent aluminum road and cross market with their new MkI road and cross frames—all made in their 500 square foot shop so tidy you would think you just walked into a boutique car shop. Here’s what he has to say for himself.
Why aluminum? I like the look of oversized tubing as opposed to steel frames but I also wanted to make racing bikes and aluminum is a great material for that, dollar per dollar it’s the most effective material for racing. It’s really versatile in that you can make a really stiff bike and you can make really comfortable bike contrary to popular belief.
It’s just how you shape the tubes.
Aluminum is softer than steel and it’s not as rigid and brittle as epoxy which you find in carbon fiber.
How many frames do you make now? 12 frames every four weeks, and we stop 4 weeks out of the year. So that’s about 120 bikes a year.
Describe your bikes in five words: Beautiful, aggressive, well-designed, well-made, fast.
Why #thismachinekillscarbon? Because if you get on our bikes you won’t feel any disadvantage because you’re on an aluminum bike. I came up with that hashtag myself. The full quote is “this machine kills carbon and your preconceived notion of superiority.”
That’s what we’re setting out to do with our road bike. It started happening now in the industry where big brands are investing into high-end aluminum bikes. Specialized with their Allez which is a beautiful bike in my opinion. Some people are starting to realize that barring from buying the highest end carbon frame you can get just as good if not better performance out of aluminum. One of my bikes will ride much better than a similar-priced carbon bike. You’ll feel the difference.
Uphill or downhill: Downhill.
Favorite riding place: Riding in Marin is awesome, riding through traffic is fun. I used to love riding the city loop
One thing people don’t know about you: I am working on getting my pilot license.
Favorite music: Bands that I grown up loving: the Ramones. Jonathan Richmond, jimmy Hendrix, Lou reed, a lot of stuff from late 70s, early 80s. I play the guitar.
What are you most proud of? That I’ve able to keep this going for five years. Most businesses fail within the first year. I am proud that it took off to begin with. We have a shit ton of struggle keeping the business going. But I am just really proud that I did something people like. For me that’s awesome. It’s validating.
How long does it take to produce one frame: About 30 hours per bike.
Morning or night person: Both. I don’t sleep that much. I go to bed late and wake up early.
