NAHBS 2015: ENVE Teases New Dual Bolt Seatpost Design, Plus More Details on GRD Fork and Chris King 12mm Prototype Hubs!

Machine cycles campagnolo competition enve seat post (2)

It seems that ENVE had more than one surprise when it comes to new products hidden in plain sight. Following the discovery of their new GRD thru axle disc fork with the clever removable fender, we spotted an all new seatpost design on a beautiful bike from Machine Cycles. It turns out that the post was used on a number of show bikes hinting towards a launch in the near future.

Not much is known about the post other than the fact that it is no longer a single bolt design. Now with opposing bolts and what looks like two separate wedge systems, our guess would be that the twin bolt design may allow for separate fore/aft and angle adjustments. More details next…


NAHBS 2015: WTB gives new Ci24 carbon mountain bike rims a fat chance

prototype WTB Ci24 carbon fiber mountain bike rims

Spotted on Chris Chance’s new Yo Eddy hardtails are a couple WTB Ci24 carbon fiber mountain bike rims. Word is they chose to show them off with Chance’s bikes to celebrate the fact that both brands have been on the dirt for a long, long time.

But, like the new bikes, these rims aren’t looking too far into the past. Built with a 24mm inside width, they’re coming in 29″ and 27.5″ sizes for sure, and these particular ones have 32 holes. Other than that, specs and details are being held until the Taipei show later this month. But hey, we’ve got pics!


NAHBS 2015: Stinner’s steel bikes tease prototype ENVE Gravel Road fork w/ integrated fender


Stinner Frameworks‘ backlog had grown by 8x over a three month period, so it was time to expand. So they recently moved into new production space in Santa Barbara, CA, and he’s no longer a one man show in the garage. Aaron Stinner still does all the welding, but they’ve added a painter (bringing it in house, which improves lead times and gives them more control), a fabricator and an engineer that helps with admin and operations. That’s five full time people all total, a big jump that indicates he’s doing something right.

Road and cyclocross are the bread and butter, but he also builds mountain bikes. Everything’s full custom, so he can do, touring and and gravel bikes, too, and was showing one off with a prototype ENVE gravel bike fork and fender combo…


Pedal at Highway Speeds with the RAHT Racer


For some, commuting to work by bicycle can be a drag. There is the preparation time required to kit up, packing lunch, packing clothes and the motivation factor. Sure, you may be the type who is organized and carted the week’s clothes into work last Friday, but swinging a leg over the top tube when the temperature is below 32º Fahrenheit isn’t everyone’s cup of tea. And, there’s the complication of lugging around a laptop or running errands during a lunchbreak.

However, for those who like to commute to work by bicycle, but are looking for similar benefits offered by an automobile, there may be a solution for you, RAHT Racer; Recumbent-Automotive-Human-Transport. It takes pedal power to a whole new level… READ MORE ->

Cyclocross Worlds Tech Finds: Prototypes and Pro Tips, Part 2


We’re back for another roundup of tech details from last weekend’s Cyclocross Worlds in Tábor. Today we’ll start off with the bike of young Dutchman and new world champ Mathieu van der Poel, as he kept a couple of mechanics busy going over his four prototype bikes in prep for Sunday’s big race. The biggest secret we could weasel out of them was probably their heavy use of spray-on wax polish. Besides making frames, helmets, and shoes look sparkly and new, it also does a bit to keep mud from sticking and certainly makes it easier to quickly wash the mud off that does build-up on the bike.

Follow past the break again for part two, where we’ll look a bit more behind the scenes at the prep for the final elite men’s race…


Cyclocross Worlds Tech Finds: Prototypes and Pro Tips, Part 1


Women’s World Champion Pauline Ferrand-Prevot’s muddy 140mm Freeza disc and Di2-equipped Liv-Giant Brava Advanced Pro

We spent last weekend standing out in the cold and snow flurries of Tábor, an hour south of Prague, screaming at cross racers riding around in circles. In between bourbon, beers, and cow bell ringing, we also sought out anything interesting from a tech perspective that we could pass on to you. There were several prototypes from tires to frames, that we’ll offer our guess as to whether they’ll make it to market.

We met with several professional mechanics and the odd directeur sportif to see what kind of special prep they were doing for bikes for a world championship. Some had worked dozens of worlds and had the wisdom to show for it, while a few were there for the first time and just happy to soak in the atmosphere. We also had a chance to get out on the course for a bit with some of the pros pre-riding the course to test out a couple of the bikes we have on test and to help some friends figure out which tires to ride for the changing frozen and muddy track.

So click on through for our first part, and we’ll try to give you a little behind the scenes insight into a bunch of things stood out for us…


Bike Check: Neko Mulally’s new Scott Gambler w/ prototype Fox shock

Neko Mulally Scott Gambler Dh bike with prototype dual high-low speed compression and rebound coil shock

Having moved to Asheville, NC, last year, gravity phenom Neko Mulally showed up for a Scott Bicycles demo ride at Billy Goat Bikes recently and gave us the run down on his new team bike.

The frame is the 2015 Scott Gambler with 27.5″ wheels that was introduced last summer, and a Scott rep informed the model will carryover unchanged for 2016, save for the likely spec updates. We were thinking there might be a carbon version coming, but the official word is that the riders are doing quite well on the alloy bike and are very happy with it. Neko’s been testing a coil version of a new dual high/low speed compression/rebound Fox shock for a couple months now, we just couldn’t photograph it the first time he showed it to us. We spotted a prototype Fox air shock using the same new damping controls in testing earlier, and our source tells us Neko could be swapping that in soon, too.

Drop in for a little Q&A and closeup pics…


SRAM Wireless Electronic Road Group Spotted (Again) at Tour Down Under Warmups

SRAM Red wireless electronic road group closeup photos from Gravel Cyclist at Tour Down Under 2015

Spotted by Jayson of while riding along with the AG2R during training in Australia prior to the Tour Down Under, these SRAM wireless electronic front and rear derailleurs are looking pretty darn polished.

Mounted to Christophe Riblon’s Focus Izalco Max road bike, there’s at least one detail we hadn’t quite picked up on in the already profuse collection of photos and technical data we’ve amassed on this group. The tops of each derailleur appear to have a similar looking hatch, which we’re guessing hides the charging port. Micro-USB would be our guess, since it would allow both charging and firmware updates. Plenty of closeups and links below…


Prototype Smith aero helmet spotted in the wind tunnel atop UHC


Photo: UHCprocycling on Twitter

We’d heard rumor late last year that the United Health Care pro cycling team was helping test a new aero helmet from Smith, and now it looks like they’re taking it the wind tunnel. The pic above was tweeted from @UHCprocycling and shows the helmet being worn by Slovenian cyclist Janez Brajkovič in the Faster AZ tunnel. No details to report, but it’s certainly less exotic looking (in a good way) than some other aero helmets on the market. No doubt the visor takes advantage of Smith’s experience with optics, and we’re guessing it’ll come in a few different tints if/when the helmet comes to market. Here’s what Smith’s marketing rep Cassie Abel could tell us for now:

“SMITH is committed to the experience. Our goal is to elevate human performance through essential product evolution. The cornerstone of our long-term partnership with UnitedHealthcare Pro Cycling Team is collaborating on the development of next-level products that meet the needs and demands of cyclists while offering superior protection with aerodynamic innovations. SMITH is working closely with UHC to bring a new TT helmet to market as part of our 2016 product assortment with more details of the project to emerge Summer 2015.”
