Zipp updates Service Course stems, seatposts with new options, better usability (updated)


Zipp has just announced an all-new collection of Service Course stems and seatposts, with both technical refinements and more fit options. The changes spread across both the standard and SL levels and carry with them fresh graphics, too.

For the stems, shapes are refined from prior models, and it’s more than just aesthetics. They claim small improvements in both stiffness-to-weight ratios and overall weight. Also, MSRP prices are a bit lower, too, helping fit them onto more bikes and into more budgets.

Above, the new Service Course SL OS comes with an oversized steerer tube clamp section for 1-1/4″ steerers. That gives Giant and Canyon bike owners another cockpit option, but it also gives the majority of riders more angle options to fine tune their fit. On the 1-1/4″ steerer it’s fixed at +/- 6º. But, using the included shims and adapters, anyone with a normal 1-1/8″ steerer can now get +/- 4º, 6º or 8º angles.

UPDATED: Comparison to 2014 models added and small corrections made.

But that’s not the only new option…


2016 Axle Standards, Part 2: Mountain bikes get 15×110 – Road gets 12mm thru axles

2016 front axle standards for mountain bike will be 15x110

Alongside the changes coming to rear wheels with the new Boost 148 standard, two new options will be offered up front in 2016: 15×110 for mountain bikes and 12×100 for road and cyclocross.

Starting with the new MTB standard, the goal here is much simpler. Where Boost 148 allows for a wide array of geometry and suspension benefits on top of the stiffer wheel platform, the front has just two missions: : Stiffer wheels and better tire clearance.

The current hub standard for mountain bikes is 100mm wide, so going to 110mm is a bigger overall change than the 6mm change in the rear. Presumably, that’ll benefit front wheel stiffness even more.

“15×110 can be taken almost as a parallel to the 148, it’s like Boost Front,” says Mike Gann, Niner’s COO. “If people are paranoid about wheel deflection and wheel stiffness, it’s going to make a larger format wheel (read: 29ers) feel different. And it seems like it’s really going to be pursued by a good chunk of the industry.”

The change also opens up tire clearance by about 0.4 inches. That’s the difference between shoehorning a 2.5 or almost a full 3.0 tire in the fork. That 3.0 figure, coincidentally, seems to be the poster boy for the upcoming “plus” sized wave of bikes, made much more possible thanks to these new axle standards…


Aaron Chase Vs. Bilenky Junkyard Cross: Through My Eyes Ep. 6

You probably wouldn’t expect to see Aaron Chase race cyclocross on his dirt jumper, but then again this wasn’t your average race.  Called the Bilenky Junkyard Cross, the race has become a Philadelphia institution with riders tearing through an active junkyard for the ninth time. If that name sounds familiar, it’s probably due to the fact that when they’re not putting on wild cross races, Bilenky builds some amazing bikes.

As he admits, Aaron Chase can be talked into just about anything so he and George Ryan loaded up the truck with their dirt jumpers and a kicker ramp and made their way to the junkyard. RedBull was there to capture the action which included flips, sidehacks, and plenty of junkyard slime.

Marin Smooths out Pavement Line for 2015, Offers More Tech, Better Value

Thinking of ditching your car for a bike in the New Year? Thanks to ever increasing bicycle infrastructure and the work of advocacy groups like People for Bikes, it’s becoming easier than ever to do so. Even if you don’t plan on completely giving up on your automobile, a dedicated city bike can make errands by bike a pleasure rather than a chore.

You could easily spend a fortune on a new bike, but for many riders looking to bicycles for transportation, value is as important as performance. Based on their Pavement line up for 2015, Marin seems to understand the concept as well as any manufacturer. Nearly everything in the Pavement line is new with fresh frames, improved spec, and better value. On various frames you’ll find internal cable routing, improved disc mounts, and more integrated accessories and accessory mounts than ever making it easier to just jump on and ride.

Commuter ready right out of the box, the Fairfax SC6 DLX is one of the more interesting bikes in the line up. Complete with a Shimano Alfine 11 speed internal gear hub, Gates Center Track belt drive, Shimano hydraulic disc brakes puncture resistant tires, the SC6 DLX adds commuting ease with a Super Nova E3 lighting system that receives power through the front dynamo hub. An integrated fender/rear Ractime Custom Integrated Match-It QL3 rack system makes rides in sloppy conditions a bit more pleasant, and the entire bike with all the accessories comes in under 30 lbs (28.28 lbs). As the top level Fairfax the price reflects that, but at $2399 complete, the bike is still a bargain.

That theme continues with the rest of the models after the break…


Chez Velo hacks Gevenalle w/ SRAM TT shifter on amazing 11-speed 28″ cyclocross concept bike

Chez Velo gevenalle retroshift hack with SRAM TT 11-speed shifter

Gevenalle has been making quite a bit of headway lately, offering everything from mechanical and hydraulic brake levers matched to mechanical shift levers that can be set to either indexed or friction shift with models for short or long cable pull. One thing it can’t do (yet) is mate up to 11 speed cassettes.

But that didn’t stop Chez Velo, who wanted to use the simple, durable shifter lever combo to build up a slick 1×11 cyclocross bike, so they hacked it. By reversing the cable pull direction and mating a carbon SRAM TT shifter blade to it, they were able to make it work. But that’s really just the beginning of this incredibly cool build…


New TRP Carbon Cyclocross Fork Spotted at Races

TRP Carbon Cyclocross disc brake fork fork

If you make brakes, you know they’ve gotta end up on something. So, TRP decided to start making their own carbon forks to create a more tightly integrated system. We suspect that means ideal cable routing, but has one in for a detailed first look and gave us a few tidbits to share with you.

They first spotted it at the Milton Keynes UCI cyclocross World Cup race, so it’s likely aimed more at the big clearance, off road racing crowd than the pavement pounders. Check out a few details below…


No. 22 Bicycles Launches Ti Broken Arrow Cyclocross Bike, Barriers Don’t Stand a Chance

We may be over halfway through Cyclocross season, but that doesn’t mean it’s too soon to begin thinking about your ride for 2015. Especially if you’re considering a dream build which may take some time to put together. Perhaps you’re considering something titanium, something like the new Broken Arrow from No.22 Bicycles.

At this point, we have come to expect gorgeous, functional bikes from the Canadian company building their titanium fleet in the U.S., and the Broken Arrow is no different. Using many of the same craftsmen that made Serotta and Saratoga Frameworks possible, bicycles out of No.22 boast impressive welds, immaculate finishing, but are still built to get dirty.

As the perfect cyclocross frame material in their opinion, the Broken Arrow uses cold worked stress relieved 3Al-2.5V titanium tubing to provide an extremely durable frame that will hold up to the abuse of cross. Durability is key, but so is ride quality, so to ensure the perfect ride for any rider each frame uses titanium tubing that is double or triple butted by use of a CNC lathe. The ability to control the butting process results in varied wall thickness for different size frames resulting in a size specific titanium tubing.

Considering complete CX1 builds start at just $5,499, the Broken Arrow might be the perfect high end addition to your quiver…


Pacenti Launches SL25 Disc Brake Specific, Tubeless Ready Rims

Pacenti SL25 disc brake rims for road bike cyclocross and gravel bikes

Kirk Pacenti is following up his SL23 with a new disc brake specific rim that’s a bit wider and tubeless ready, perfect for everything we’re fans of when it comes to skinny tires.

Compared to the SL23, there are a lot of changes that make it disc specific:

“We obviously don’t need any extra material in the brake track,” Kirk told us. “So we shifted that to the spoke bed since they’ll see higher loads with the disc brakes. And we opened up the internal width a little bit. It goes from 18mm to 20mm wide inside by reducing the hook width, which is thanks to not needing a brake track. So external width is the same.

“We also increased the depth of the bead well in the center to make them easier to set up. The only complaint we ever had with the SL23 was that it was hard to setup, so this makes it easier.”


How Low Can Your Gauge Go? Kappius Offers Incredibly Accurate Pressure Gauges

Kappius pressure gauge fat bike cross ultra low bicycle

A lot has been made recently about bicycle pumps and the ability of their gauges to be accurate at low pressures. Most tend to maintain the highest level of precision at pressures well above where the average fat bike, cyclocross bike, or even mountain bike is run. One or two psi off might not seem like much, but when you’re only running 10 psi, up to 20% variance is a big deal.

Apparently, when Brady Kappius isn’t busy rethinking bicycle hubs and designing complete wheels, there is enough time to come up with gems like his new Digitial Pressure Gauge. Available in 3 varieties, the Gauge will be sold in Fat Bike, Cyclocross/Low MTB, and Cyclocross/MTB pressure ranges. The Fat Bike model will measure from 0-15 psi with 0.01 psi resolution, then 0-30 psi also with 0.01 psi resolution for the Cyclocross/Low MTB option, and finally 0-50 psi with 0.02 resolution for the Cyclocross/MTB gauge all with a +/- 1% accuracy.

Each gauge is for presta valves only and includes a bleeder valve so you can pump up the tire past the desired pressure, then bleed it down to the precise number. Powered by an included 9v battery, the gauge has a 20 minute auto off feature, and each model has a pressure limit that is twice the intended pressure range (so don’t use the fat bike model on your road bike!). Available for pre-order currently on the Kappius store, each gauge will run $159.99 with your choice of units and will look slightly different than the early prototype gauge above.
