A Cardboard Bike with 3D Printed Parts and Aero Bike’s Wooden Beam Bicycle

Aero wooden bicycle, lifestyle shot

It’s pretty interesting that creative designers and engineers sometimes build bicycles to pursue the study of new ideas or concepts. It piques our interest even further when the frame construction materials are a little outside the box…or perhaps part of the box (or crate)!

Two rather peculiar bikes have recently been created as engineering projects, one made almost entirely from cardboard and the other featuring an architecturally inspired wooden frame. While neither was made with the specific focus on producing a marketable bicycle, the Aero wooden bike seen above may not remain a prototype forever.

Money doesn’t grow on trees, but will bikes one day? Click below the break to see…

SOC15: Prototype Salsa 27.5+ full suspension mountain bike decorates WTB booth

Prototype Salsa 275-plus full suspension mountain bike

Looking very similar in design to their Horsethief 29er full suspension bikes, this prototype carbon bike showed off an upcoming Salsa model made to fit wider wheels, like those built with WTB Scraper rims and Trailblazer 2.8 / Bridger 3.0 tires.

Official details are slim, but we’ve got a little info and plenty of pics…


Triple Bottom Line’s DFM01 concept accomplishes sustainable customization through 3D printed titanium


When sustainability-focused designer Satoshi Yanagisawa of Japanese firm Triple Bottom Line approached the production bicycle, he saw opportunity in material optimization and customization per user. The result of his efforts is the DFM01, a cleverly designed and weight-competitive (the concept is 15.4lb when built into a complete bike) carbon fiber and titanium frame that can be reconfigured and printed custom around each user through an evolving geometry algorithm.

Triple Bottom Line is currently testing the product to establish viability with the goal of making it available to the public. It will be on display at the London Design Festival this Fall, but you can take a sneak peek here… READ MORE ->

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.

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!


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.
