NAHBS 2016 – Crumpton goes short & wide with prototype Type 5 Disc road bike

prototype crumpton type 5 disc brake road bike

Nick Crumpton, who took a year off from exhibiting at NAHBS, is back and he says he’s starting to move away from trying to be every weight weenie’s dream. Not that things are getting heavy, but the absolute gram counting we’ve seen in the past isn’t the focus.

Now, it’s a new disc brake option for his Type 5 carbon road bike. It’ll use flat mount calipers and 135mm rear spacing, but what sets it apart is its ability to run massive tires while retaining a very tight rear end.

Crumpton’s normal road bikes typically don’t go shorter than 412mm on the chainstays. Here, he only had to extend it to 415mm, which is the minimum recommended by Shimano when running disc brakes and the wider rear axle spacing. But, it can run full size gearing on the cranks and a massive 32mm tire on wide rims with no problems…

F-1 engineering expertise helps North Bucks Machining create this CNC’d downhill bike

NBM CNC machined DH bike, side shot

Although it isn’t the method of choice for any large bicycle manufacturers, it would be cool to see more effort go into creating CNC machined frames, if only because they tend to look pretty awesome! This eye catching downhill bike was built by Stewart Palmer, a fifth generation engineer with past experience machining F1 race car components and high performance engine parts.

After his Dad’s job became redundant, Stewart’s parents founded North Bucks Machining in 2011 and took their son and daughter on as employees. Stewart enjoys riding in his spare time, and with the dream of creating his own project suddenly possible he spent 18 months designing and building his first bike frame…

Team-exclusive Orbea Orca Disc brake road bike for Cofidis, new budget model for rest of us

2016 Orbea Orca Disc brake road bike exclusively for Team Cofidis

While the window between when the pros get the new stuff and the rest of us do narrows each year, they still get many of the best things early in the race season while we wait for summer release schedules to roll around.

Case in point, the team-exclusive Orbea Orca Disc, a new bike for Cofidis to race the classics upon. The Avant Disc came out in 2013, so it’s not the Spanish brand’s first disc road bike, but it is the first intended for the pro peloton. It’s decked out with components from team sponsors Shimano, Prologo and FSA, and we pulled a few screen grabs from their team’s promo video to show frame details while we await response from Orbea for more info

UPDATE: Orbea’s response about the new bike below!

Netherlands university students demonstrate new 3-D printing technology with the Arc Bicycle

Arc 3D printed steel bicycle, feature image

Arc 3D printed steel bicycle, side

While here in North America we’re all excited about the NAHBS celebration of hand-built bicycles, this crazy looking bike would be an excellent candidate for a European Robot Built Bike Show (ERBBS?) if such a thing existed.

Students from TU Delft’s Industrial Design Engineering Faculty in the Netherlands spent three months designing the webbed/net-like frame. The Arc Bicycle was then manufactured from stainless steel by an Amsterdam-based research and development company called MX3D who specializes in multi-axis 3-D printing.

A bicycle was chosen by the students as a test piece due to the complex forces bike frames typically endure- not to mention that Amsterdam’s people absolutely love bikes to begin with. The Arc bicycle is fully functional, check out the video below to see robotic arms building it and one of the students taking it for a spin…

Like any great cyclocross venue, the CX Nationals expo area was a bit of a party. In addition to food, warm beverages, and warm up tents, there were also a number of companies with things to show – some serious, some not so much.

Industry Nine has their products pretty well buttoned up now that their Trail S wheels are on the scene, so the big draw in their booth was something a little more… deadly?

Wavetrans bicycle transmission provides seamless CVT-style shifting

Wavetrans bicycle transmission

wavetrans-cvt-bicycle-transmission-prototype

If you’ve ever driven a snowmobile or a car equipped with a CVT transmission, you’ll know how smooth the engines feel as they shuffle through their “gears”. With the creation of the Wavetrans bicycle transmission, that kind of smoothness could find its way onto your bicycle.

The Wavetrans is an electronically controlled drivetrain with a single front ring that expands or contracts to provide the equivalent of six different gears. The innovative concept claims to offer several benefits versus traditional derailleur setups. It provides a seamless feeling while you shift, can be shifted under load, operates quietly and smoothly, won’t double shift like derailleurs can, digitally displays what gear you’re in, and the inventor claims the chain will never fall off.

Currently only one prototype exists and actual production is a ways off, but it’s certainly an interesting idea. Video and more details below…
