First photo taken with Glass was a nearby Google bike
Wondering what we’re doing with Google Glass and what a glanceable computer is? Get caught up on Google’s page and Bike Hugger is participating in the Glass Explorers program, the second group.
There are two Explorer groups actively receiving Glass. The first 2,000 recipients are developers from Google I/O 2012. The other Explorer group are the selected 8,000 #ifihadglass participants.
After sharing this idea and getting invited to the program
#ifihadglass would share with you how a bike is made from concept, to welding, to assembly, and then the first ride.
Glass is a heads-up display in an eyewear form factor that does everything from maps, photos, voice search, and video calls to email, calendar, Google Now and videos. I call this category of device a glanceable computer because a few important things to do are a glance away.
View the photos taken and videos recorded so far with Glass on my G+ profile, including in this gallery. On rides I’ve recorded singletrack, bike paths, and the road. Also a writing a feature story about Glass and the bike for Wired. To date though, the best use of Glass has been beer tasting with Kevin Tamura.

As it breaks in, the Di2 9070 servo motor sound changes to that of a tiny, robotic screech owl call, indicating what chainring you’re in, protesting so much shifting.
Whir, shift, whir. You get used to the sound and can tell up from down.
The chain-bound robot shifts on command following its programming with perfection and it works as well as a Swiss watch movement. That’s until an unanticipated variable enters the equation, like a hard shift with a twisting frame under acceleration or when the slightest impact bends a derailer hanger out of alignment, even by a millimeter.
The pros get hardened hangers that don’t bend when you turn right and cough too hard
The drivetrain arms race between the Italians, Germans, and Japanese has them focused on cramming 11 cogs into a cassette, and with electronics or hydraulics. Brand loyalists celebrate their success like they took a bicycle beachhead, but all of them have failed and ignored a critical component of their respective drivetrains: how it hangs on the bike.
When asked what’s going on with Di2 in the Tour or mishaps from Campy, and SRAM, I respond, “derailer hangers soft like overcooked linguini probably caused it.”
Mark V writes about the replaceable derailer hanger in Issue 02 of our magazine. Why they’re replaceable, so soft, and how you can bend one with your hand, or leaning it against a tree during a stop on a ride. Also, why sometimes innovation results in very unfortunate products.
The solution seemed simple enough: a replaceable derailleur hanger that could be aligned without consequence. Even if the hanger snapped, a new one could be fitted. In fact, if the hanger was designed such that it preferentially bent before the frame suffered any damage, so much the better. This is especially true of carbon fibre frames. However, the derailleur hangers one typically finds on a stock bike bend like overcooked linguini.

Back to the whir, shift, whir…it’s shifting perfection that isolates riders. Failing from the lack of a human touch or emotion and a too soft derailer hanger.
SRAM RED 22 Hydro R (hydraulic rim brakes) was raced for the first time at the Tour. I mentioned that earlier with a post about Cav’s bike. Since then, SRAM dispatched a team to the Tour to document the event. We’ve got Hydro R installed on a bike and riding it now. See my initial review when I rode it in SoCal.
Writing from the Tour SRAM said
After we received acceptance from the sports governing body in June, it was obvious that SRAM RED 22 featuring hydraulic road rim brakes could and should be raced as soon as possible, and our professional teams emphatically agreed. The best opportunity to for Twenty-two HydroR installations were during the Tour’s second week. SRAM staff were joined by team mechanics from both Saxo-Tinkoff Team and Omega Pharma-Quick-Step Pro Cycling Team in SRAM’s German headquarters, where two full days of bike builds and technical training took place.
What SRAM RED 22 does is deliver a wider and smoother gear ratio, including the 16. Yep that’s another click in your drivetrain with an 11x26. As I’ve been describing HydroR to cyclists that ask, you know how you brake in a car? A little toe tap here and there and sometimes a full press when needed? Same thing with HydroR and that’s the bigger innovation than an 11-speed or arguably shifting with servo motors. In the simplest terms, you have far more control, modulation, and confidence with hydraulic brakes. It’s a slight or hard pull when needed.
SRAM has equipped Specialized Venges & Tarmac SL4s with HyrdoR at the Tour and see this gallery of the bikes in France. SRAM-sponsored Tour racers have the choice to ride the new kit and are expected to do so for more stages, including the 21st into Paris.
