Scott 3Rox Mountain Bike Team Plays Hide the Di2 Battery

Scott-3Rox-team-mountain-bikes-hidden-di2-battery05

Way back in the spring of 2012, Geoff Kabush’s Scott Spark revealed the first look at the Shimano/Fox electronic integration, using a Di2 battery to power the iCD lockouts for both fork and shock. At that time, it was pure prototype. Things got official the following April with Fox’s formal introduction, which was preceded by a second look at Kabush’s bike.

Now, the 3Rox team continues to tweak their electronic lockout set up with the new internal Shimano “seatpost” battery. Except they didn’t stick it in the seatpost…

Updated Gear Ratios: Comparing SRAM and Shimano’s 1x Drivetrains with XTR M9000

Shimano XTR m9000 11 speed 1x 2x  3x (19)

Not too long ago, Switchback Bikes posted an excellent gear ratio comparison chart that was put together by Daryl Smith. Obviously, when Daryl put the chart together the new option packed XTR M9000 group was still under wraps, so the comparison to its 11-40 wide range cassette couldn’t be made. To keep with the times Daryl has updated his chart to include the 1x options for an XTR group.

Crunch the numbers after the jump…

Null Winds’ Upper Wheel Fairings Blinds Headwinds with Science

null-winds-upper-wheel-fairings

Null Winds Technology has taken their Upper Wheel Fairings to Kickstarter to bring wind cheating shields to the masses.

Admittedly, they’re not for racers. And they’re different looking. But the science is interesting, so let’s have a look. Inventor Garth Magee says wind speed affecting the top of the wheel is up to 3x the speed of the headwind. That’s because the tire and spokes are all rolling directly into the wind at twice the speed of the bicycle. Of course it’s variable based on head wind speed and bicycle speed, but the power needed to overcome the drag rises in proportion to the cube of the wind speed. So, the faster the wind and the faster you try to go, the more power you’ll have to pump out for smaller and smaller gains.

His Upper Wheel Fairings block the spokes from “fanning” the wind against your efforts. Magee says the result is up to 20% more speed for a given effort…

SOC 14: More Anodizing, Hubs, and Lefty Supermax adapters from Project 321

Project 321 anodized lefty max hub cannondale sis2 cranks stan's wheels (8)

Given the fact that we seem to be heading into a renaissance of Day-Glo colors and color matched anodized parts, consumers seem to be paying more attention than ever to the individual components of their bikes. Those looking for colorfully anodized parts are at the company’s mercy hoping they will eventually offer what they want in the color they like, or can look to the anodization experts like the folks at 321 Components. We spotted Project 321 pushing around an Ibis with some Pink Thomson bits at last year’s SOC, so we wanted to stop by their booth and see what they have been working on since. The answer is more colors, more hubs, and more Lefty compatibility…

Hack! Custom Di2 Buttons Paired with Magura RT8TT Hydraulic Brakes on Triathlon Bike

Alexs Bicycle Pro Shop Di2 hack with remote buttons on a Cervelo P5 triathlon bike with Magura RT8 hydraulic brakes

What happens when you want hydraulic brakes with electronic shifting on a top end triathlon bike? Well, you could use Shimano’s stock bar end and climber’s shifter pods. Or, for about the same price or less, you could take your existing parts to Alex’s Bicycle Pro Shop and have them create some very slick stealth buttons placed right where you need them by the Magura RT8 hydraulic brake levers. Here’s what Julian Da Silva from the shop had to say:

I wanted to show you guys a cool little project I worked on for a customer who wanted to utilize Di2 shifters on his hydraulic brakes that came with his Cervelo P5 Six. The customer had a spare sprinter switch that he wanted me to use, so naturally from my experience playing with the di2 components, I was able to take it apart and make some modifications. The circuit board is a simple design with a common ground and positive switch. I tapped into the circuit and utilized a tactile momentary push button to act as the independent buttons on the brakes. The customer requested that he only wanted to operate the rear shifter, but if someone wanted to do front and rear, it would be no problem. This technology can be outfitted to work for disabled riders as para-athletes or take it a step further as another form of customization.

We charged $150 to do this service, this is of course if the customer has a spare shifter already.

Absolute Black Unveils 4-Cog 40-Tooth Oversized Cassette Adapter

absoluteblack-28-to-40-tooth-cassette-adapter

The oversized cassette hacks brigade just keeps on rolling, this time with a unique entry from Absolute Black.

Rather than replace just the single top cog, AB’s offering adds a 40t large cog onto a single piece of machined aluminum containing your 28, 32 and 36 cogs, too. Founder Marcin says the benefits are three-fold. First, it’s a stiffer unit as a cluster, so shifting should be very precise. Second, there’s more surface contact area on the freehub body, so less likely to dig into it and get stuck.

Third, it’ll weigh a lot less. How much so? Shift down and see…

NAHBS 2014: Brad Bingham Builds Eriksen a Full Custom Fatty, Gives Marzocchi Bombers New Life

Eriksen Bradti fat bike suspension fork Mike Curiak (2)

This was one of my favorite bikes of the show. Yeah, yeah, I love fat bikes – but I am also a total bike geek and projects like this make me happy. Called the BradTi, this is the creation of Kent Eriksen’s master welder and there is much more than meets the eye. Obviously, it’s a fat bike with a suspension fork, but it’s the amount of custom fabrication that it took to achieve which is really impressive…

Exclusive First Look: OneUp Components’ 16-Tooth Cassette Adapter Cog Splits the Difference!

OneUp Components 16t replacement cog for cassette upgrades to oversized large cogs

When SRAM first introduced their 11-speed Red22 group, they made a big deal about it having a 16t cog in the mix. Sure, it was tongue in cheek, but indeed, 16 seems to be the magic number now that oversized large cog cassette adapters are all the rage. Fortunately, you don’t need to pull apart a perfectly good road cassette to get your 16-tooth fix.

OneUp Components has just introduced a 16-tooth cog to slot in between the 13 and 19, smoothing out the jump to just three teeth on either side. It replaces both the 15 and 17 when adding their (or any other) oversized 40t or 42t large cog. The result is an even transition at the smaller end of the cassette, eliminating any 4-tooth gap.

We mated it and their new 40t cog to an XTR 10-speed cassette. Tech details, weights and first impressions below…
