The Bike That Got Away With Sky Boyer Of Velo Cult: Part 2

velocult sky boyer hanebrink 8

“The Bike That Got Away” is a series of interviews intended to showcase the best bikes of all time from the perspective of the diverse characters that make up the cycling industry. It’s an opportunity to look back fondly (or not at all) on vintage technology, paint jobs – whatever made or continues to make bikes compelling and awesome. These are the bikes that have shaped us as industry members, dealers, cyclists, and super fans.

Read Part 1 of this piece to get up to speed. 

Now for part two, we’ll dive into more about that wild Hanebrink fat bike we briefly covered at Sea Otter…

Jan Workshop Shapes a new Wooden Bike with Stunning Continuous Beam Frame

jan wood bike frame 3

Joining the ranks of bike builders who have turned to natural materials for bike frame and component construction, Prague-based studio Jan (named for partners Jan Muscka and Jan Vidlicka), construct frames out of wood. Taking a new approach to the material, Jan constructs an “avocado” shaped continuous beam, utilizing over forty laminated layers of veneer, then carves the frame characteristics and interfaces from that platform. The final product is both visually unique, durable, and, as they boast, naturally beneficial in enhancing ride characteristics. Several prototypes in, the studio is now accepting outside orders.

Check out this unique Czech design after the jump. READ MORE ->

Bike Check: Geoff Gulevich’s Rocky Mountain Slayer SS with Prototype Manitou Fork

Geoff Gullevich prototype manitou dirt jumper rocky mountain (4)

Gully gets all the cool parts. That’s not surprising though considering is always entertaining both on and off the bike, plus a genuinely nice guy to boot. This year after taking in the Manitou presentation for the all new Magnum Plus suspension fork, Geoff let us check out his slopestyle bike since he was on hand as a Manitou, Answer, and Sun Ringle sponsored athlete. In addition to sporting one of the raddest paint jobs we’ve seen in a while, Geoff’s Rocky Mountain Slayer SS was running an interesting suspension fork that we haven’t seen before…

SOC15: e*thirteen extended range cassette handles XD Driver differently, plus new cranks & more!

e13-EXF-extended-range-cassette-9t-42t09

e*thirteen had a plethora of prototypes on hand, only showing off things that are at least a few months out. The most interesting was this prototype EXF Cassette, which will offer a wide range set of cogs that runs from a 9-tooth up to 42-tooth in both 10 and 11 speed options. Following that will be an 8-speed version for DH, but that one’s still in testing with the Polygon/UR Team.

Weights should be in between XX1 and XTR, but it should come in much cheaper. Final MSRP is TBD. The lower cluster is steel, made in two pieces that are bolted together.

The upper 3-tooth cluster is aluminum and slides onto the freehub body portion of an XD Driver with a lock ring that holds that piece in place to attach the cassette to the wheel. Then the lower cluster slots into the upper section and a chain whip is used to twist and lock it into place. Wanna see the back side?

Spotted: XX1 Replacement Cassette Cog from Wolf Tooth Components

WTC xx1 cassette ring

One by drivetrains are great for dropping weight and simplifying your drivetrain. They also seem to be great for manufacturers as the move to ditch the front derailleur has resulted in a number of companies springing up to provide parts to fill in the gaps. Companies like Wolf Tooth Components offer up parts to piece together your own one by drivetrain, but also to address another issue – wear and tear.

While the SRAM XX1 cassette is a marvel of product design and engineering, it seems that may riders are finding the aluminum 42t cog to be wearing prematurely compared to the other 10 cogs in steel. OneUp components just introduced their 42t replacement with an even larger 44t cog, but for those looking to keep the standard 42 tooth count, it looks like WTC will soon have your answer…

TPE15: DVO Topaz enduro shock gets closer, Diamond suspension fork shipping now

prototype DVO Topaz enduro shock

The  DVO Topaz is their new Enduro rear shock that’ll be coming this fall. It’s a complete air shock with 3-position compression switch that goes from wide open to medium to heavily damped. That last setting is not locked out, just very firm.

The piggy back reservoir will use a bladder based, air charged chamber that manages oil displacement just like on the coil-sprung Jade. Normal shocks use a nitrogen charged chamber with an IFP floating piston, but DVO’s JP says the benefit of the bladder system is less initial stiction.

It’ll be available in 200×50, 200×57 and 215×63, retail, price and actual release date are all TBD.

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

BFS15_Cycle-Mag_cowboy-cruiser

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

Rolf Prima colored rims ceramic coating stickers (5)

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…
