Berliner Fahrradschau 2015: An Eclectic Mix of Cycling and Lifestyle Products


Another year of Berlin’s consumer Bike Show kicked off this weekend highlighting a lot of the urban and lifestyle segments of the bike industry that sometimes get glossed over with new derailleur and suspension tech. That means a lot of classic city bikes, many e-bike applications, internally geared hubs, and belt drives, plus more cargo bikes than you can shake a stick at. Over the next week or two we’ll try to roundup a bunch of things that we spotted that stood out from the crowd and the free flowing Henrick’s Gin and Tonics and German beers.

Read on for a modern take on a classic, city bikes and great finishes, some custom bags, and an e-bike to sneak on some group rides…


TPE15: KS Zeta dropper seatpost for road bikes, plus prototype wireless dropper post

KS Kind Shock wireless dropper post remote prototype

KS is focusing on all categories for dropper posts, not just mountain bikes, which helps explain the new Zeta model for road bikes. They’re also working on all manner of buttons, levers and methods for making those posts drop, like this prototype wireless dropper.

Shown above, the electronic dropper doesn’t have a formal name yet, but it’s in development. It functions the same as the others, but with an electronic valve rather than a mechanical valve and a NFC wireless remote control.

Right now, it’s a proof of concept to gauge interest and see what sort of battery interfaces make sense. It could integrate with Di2 or e-bike batteries so there’s not a separate battery pack required. The one above had a rather big, ugly battery pack attached to the seat tube just out of the pic’s lower edge.


NAHBS 2015: Rolf Gets Colorful with Prima Plus Program, Tries out New Color Coating

Love Rolf wheels but looking to get a pair that stands out from the crowd? Due to a rising interest in custom colored decal requests, Rolf is launching the Prima Plus Program. Starting with the Rolf Ares, TdF, Vigor, or Elan, customers can pick out one of nine standard colors for a custom set of die cut decals that are made to order. If the decals don’t do it for you, Rolf whipped up a one-off color coated set of wheels just for the show. It’s prototype only for now, but if there is enough interest…


Powertap Teases new Products – Crank and Pedal Based Power Meters on the Way?

powertap tease 3

Somewhat quietly released on the first day of NAHBS, PowerTap just introduced a new video that likely teases some upcoming products. Highlighting their 17 years of innovation and product development in regards to power measuring devices, PowerTap chronicles their history starting with the Tune PowerTap up to the most recent PowerTap GS.

Now, the company is giving a little taste as to what’s to come – which by the looks of things includes a crank based and pedal based power meter…


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…
