Culprit adds more teasers for cable-hiding aero stem

culprit-aero-stem-with-hidden-cable-routing-teaser-2

Coming early next year, Culprit’s aero stem is just one part of a system designed to clean up the front end of your bike and offer improved aerodynamics. They’re not letting the rest of the cat out of the bag until January, but they do seem ready to share more on this stem.

Intended to hide cables and wires for any set up and direct them out the back of the stem, it seems most useful for aero bikes that run those cables into the top of the top tube. The new images show just how visual and drag-inducing clutter they remove, and it works equally well for full mechanical systems, too…

Pioneer power meters for Campagnolo, FSA & Cannondale now shipping, MTB coming in December

pioneer cycling power meters for campagnolo FSA and cannondale road cranks now shipping

Pioneer continues to show they’re serious about cycling by announcing models for Campagnolo, FSA and Cannondale road cranksets, plus options for Shimano’s latest Dura-Ace, XT and XTR models.

The upgrade to working with the latest Dura-Ace R9100 comes as no surprise since Pioneer sponsors several top pro teams and athletes. That one, along with versions for the Campagnolo alloy cranks, is now shipping in both single and dual leg versions. The Cannondale SiSL2 and Si cranks will come in left-side only options for now and are also shipping. Pricing without the crank arms is $499 for single leg and $999 for dual. Single leg measurement comes from the left crank arm and can be upgraded to add right leg at a later date.

The FSA SL-K carbon road version and mountain bike versions will start shipping in December for Trail XT and XTR cranks. That’s not all they showed at Interbike, though, check our coverage for a look at some prototype meters that capture data from the rest of your bike (and you).

scicon_aerocomfort-road-3-0-tsa_bahrainmerida

We’ve been seeing lots of press releases from the new Bahraini pro cycling team that Vincenzo Nibali will ride for in 2017, but to be honest we’re not too concerned over which domestiques and sports directors will make the new team function day to day. On the other hand, sometimes buried in the PR is an interesting tidbit. This one takes the form of a new pair of bike travel cases from premium Italian bag maker Scicon. The new pro team will be traveling with new Scicon Aerocomfort Road and Triathlon 3.0 TSA Bike Travel Bags, as well as the updated Race Rain Bags and several others, all in their characteristic red. Jump past the break for a look inside the bags and a hint of what new tech they bring…

Filament Spin Evolution winds up lighter, stiffer and stronger carbon rims

FSE Filament Spin Evolution wound carbon fiber bicycle wheels

Imagine a set of carbon wheels that claims to have 40% better impact strength, be 40% stiffer laterally, and about 20% lighter with a rider weight limit that’s about 30% higher than normal. Think that wheelset would weigh in at 1,035g? That’s what Filament Spin Evolution has done with their 25mm deep tubulars thanks to a non-standard construction method.

FSE isn’t the first brand to do filament wound carbon rim construction, that honor goes to Venn Composites and their REV wheels. FSE’s process brings the process in house using the same process used to create F1 driveshafts and by BMW. It was originally developed by DuPont decades ago, but hasn’t seen widespread use other than limited use by Wound Up forks and tubes for Calfee and a couple other small builders. Dan Kellerbee, FSE’s managing partner, says the process loves the cylindrical shape, which is why it worked so well for those products. They were already making rims for other brands using the traditional cut and layup process, but for their own brand they found a way to do filament spinning on the rim shape…

XShifter crushes Kickstarter, adds universal wireless TT bar end shifters

We broke the news on XShifter, the universal wireless shifting conversion kit that’ll match wireless shifting to any drivetrain, and they surpassed their Kickstarter funding goal in 48 hours. Now, with just less than two weeks to go, they’ve added a TT bar end shifter option.

The unit mounts to any standard aero bar extension, and inventor Paul Gallagher told us they can also mount to the ends of drop bars. Even better, they can be paired with their other shifters, giving you the ability to shift from multiple hand positions…

Diamondback transitions into custom bike builds with Online Bike Customization Tool

diamondback-andean-custom

A few weeks ago, Diamondback broke the internet (or at least disrupted it) with the launch of their new Andean tri bike. Now, they’re using the internet to offer customers a new way to build one. When you’re spending more than a few grand on a new bike, it’s nice to be able to pick and choose your components. In order to make the consumer’s (and the shop’s) buying experience as smooth as possible, Diamondback has introduced a new online bike customization tool.

While the Custom Studio will soon expand to other bikes, for now it is limited to the radical new Andean – which can be customized with different parts, colors, and sizes…

Culprit teases multi-part aero stem for first product as a components brand

culprit-prototype-aero-bicycle-stem-teaser-1

The humble stem might not seem like the most exciting place to start, but that’s what Culprit is apparently leading with for their reboot as a components-only brand.

This 3D printed prototype shows their patent pending new design, but doesn’t come with any details yet. Based on their past product mix, we’re guessing its an evolution of the integrated cockpit designed for the Legend triathlon bike that didn’t quite make it through Kickstarter last year. The nose cone appears to pull double duty as an aerodynamic fairing and cover to hide wires and cables. They’re teasing more to come between now and a planned launch early 2017, and we’ve got a couple extra pics below…

X-Shifter’s universal wireless shifting kit goes live

xshifter-universal-wireless-bicycle-shifting-upgrade-kit

At Interbike, we spotted X-Shifter roaming the grounds with their wireless shifting upgrade kit that turns any derailleur into a wireless, quasi-electronic shifting one. Whether it’s for road or mountain bike, anything from base level up to premium units, X-Shifter connects to them and gives you control with a single thumb pad to manage both front and rear shifts.

Since we first saw them, they’ve added a road specific shifter unit, upgraded their software to include multi-shifts, optional control of both front and rear shifting in an optimized sequence for you, and added in a few more customization options that could be coming soon…
