This spy shot might be the 2017 Shimano Dura-Ace Di2

2017 Shimano Dura-Ace Di2 spy shot by Melbourne Uni Cycling Club

Thanks to a reader from Melbourne Uni Cycling Club, this pic appears to reveal the next generation Shimano Dura-Ace Di2 crankset and rear derailleur. The brake rotors also appear to be updated. While it is a surprise to see it pop up somewhere other than a major UCI pro race on team bikes, it’s not a surprise that it’s out there. Their usual product cycle led us to believe something would be shown this year -the current DA9000 group came out in 2013– and comments from other vendors who make power meters and related items reinforced that hunch.

Based on what we can see here, it remains an 11-speed group. But, that’s an awfully long derailleur cage, suggesting some wider range gearing options may be in the works for cyclocross and gravel bikes. There’s still a wire there, too.

The crank arms are a little taller, which gives the illusion of being flatter. The asymmetric four-arm spider carries on and mates to what seems to be a more robust large chainring. The teeth are darker, which could mean a hard ano finish to reduce friction.

Shimano does not typically comment on as-yet-unreleased groups, but we’ve reached out and will update with any fresh news. See anything else? Let us know in the comments!

TPE16: MicroSHIFT shocks us with new 11-speed electronic drivetrain for mountain bikes

Microshift P1100072

Microshift P1100086

Trying to develop a drivetrain is no easy feat when you consider all the patents you have to work around. Add to that the electronic drivetrains are even harder to manage because even the path the electronics operate in are patented. Even SRAM admitted it was one of the biggest challenges they faced when developing eTap. Well, microSHIFT figured it out and wired their Taipei Cycle Show booth with this functioning motorized system…

TPE16: Exclusive first look at HT’s new M1 XC Pedal plus updated AE03 Flats

Use P1100237

We had yet to hear about anything in the pipeline, but with the introduction of HT’s T1 Trail/Enduro pedal, the suspicions were high about them coming out with an XC pedal. While visiting their anodized-colored filled booth today, I asked if there was an XC pedal coming out soon… “We’ll have one at Sea Otter”, (April). I asked for a sneak peak, and after a little gleeful staring, “TC” stepped into the closet and came out with this blue puppy.

Check out the New HT M1 pedal and specs as well as some welcome updates to their AE03 flat pedal…

NAHBS 2016 – Prototype X-Fusion McQueen 27.5+ fork debuts on Retrotec mountain bikes

retrotec-275-plus-trail-mountain-bike01

When we asked Retrotec builder Curtis Inglis what he was bringing to this year’s show in our Road to NAHBS interview, he said coffee mugs. And he hinted at some 40th anniversary goodies from Chris King and “special parts” on another bike. Well, from what we can tell, those Olive Crate hubs and headset made it onto this bike, which also had an as-yet-unseen Plus fork from X-Fusion…

NAHBS 2016 – Ritchey dropper post pops up, heritage paint & complete bikes now available

prototype ritchey logic wcs dropper seatpost for mountain bikes

prototype ritchey logic wcs dropper seatpost for mountain bikes

Sitting quietly atop the Ritchey Timberwolf 27.5 hardtail trail mountain bike was a prototype dropper seatpost that, if all goes to plan, should launch later this summer.

Final spec won’t be announced until then, but the basics are: It’s a 3-position, pneumatic operation post that’ll be available in 31.6 and 30.9 diameters and 100 and 125 millimeter drop options. There’ll also be a 2-position 80mm dropper. The taller of the two will have an initial drop about 1/3 of the way down, plus all the way up and all the way down. The 80mm post will just have all the way up and down.

Why create a dropper post? Ritchey’s new marketing director Fergus Tanaka said they wanted to offer a solid performing post that’s affordable, so it should get OE placement and be attractive aftermarket. Which makes a lot of sense for a brand that has virtually every other cockpit part available…

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

prototype crumpton type 5 disc brake 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…
