Interview: Adam Clement of Gevenalle


Gevenalle, or Retroshift as it was known in the Beforetimes, was forged in the cold, muddy pits of Portland cyclocross to address a need for durable, serviceable, cross-specific componentry. Years on, founder Adam Clement continues to charge forward with the fourth version of his iconic shifter and brake lever system as well as a suite of similarly thoughtful and functional drivetrain components designed to keep racers racing in the most extreme course conditions in style…


Project: World’s Funnest Bike – Drivetrain, Wheels, Brakes & Install Notes


So far, our World’s Funnest Bike project has detailed the frame and the cockpit. Now it’s time to go over all the parts that make it go and make it stop. Most of the parts used on this project bike were new, but I did have some trusted components and lightly used parts that needed more time before a final review could be posted, so those made there way on board and will be noted.

The shifting is handled by Gevenalle’s latest GX shifter levers, which were designed around the Shimano XT rear derailleur to offer a wider range option for anyone wanting a more capable gravel/adventure/cyclocross bike. The Gevenalle parts were all weighed in with a full introduction in this post, so here we’ll go over their performance and use notes and show how it all came together with a mix of other components…


Gevenalle adds GX drop-bar shifters for Shimano 10-speed MTB derailleurs – First look & actual weights!

Gevenalle GX drop bar shifter levers for Shimano mountain bike rear derailleurs

Ever dreamt of putting a mountain bike drivetrain on your drop bar bike. You know, to create the ultimate adventure bike with wide range gearing and a fast front end?

Gevenalle has expanded their line of index-or-friction shifter equipped brake lever with the new GX model, which pulls just the right amount of cable to keep an XT rear derailleur in line with your MTB cassette. It’s compatible with Shimano’s modern clutch-equipped DynaSys and Shadow Plus 10-speed rear derailleurs with a cassette capability up to 36T. That’s a big jump from the 28T max of their BURD rear derailleur, putting you in the gearing range of the CX1 group.

Like the CX shifters, which work with Gevenalle’s own rear derailleur and other 10-speed road derailleurs, the GX gets a modified Microshift lever set attached to a Tektro lever bodies…but even those have been heavily customized and improved…


Chez Velo hacks Gevenalle w/ SRAM TT shifter on amazing 11-speed 28″ cyclocross concept bike

Chez Velo gevenalle retroshift hack with SRAM TT 11-speed shifter

Gevenalle has been making quite a bit of headway lately, offering everything from mechanical and hydraulic brake levers matched to mechanical shift levers that can be set to either indexed or friction shift with models for short or long cable pull. One thing it can’t do (yet) is mate up to 11 speed cassettes.

But that didn’t stop Chez Velo, who wanted to use the simple, durable shifter lever combo to build up a slick 1×11 cyclocross bike, so they hacked it. By reversing the cable pull direction and mating a carbon SRAM TT shifter blade to it, they were able to make it work. But that’s really just the beginning of this incredibly cool build…


Gevenalle Adds Up-Armored Front Derailleur to Cyclocross Gruppo

Gevenalle BURD Front Derailleur

Gevenalle, formerly Retroshift, just released the BURD  Front Derailleur/Chain Guide for cyclocross. Like their BURD rear derailleur, the “Blatantly Upgraded and Rebranded Derailleur” is a hacked, top-of-the-line Microshift component that they rebuilt to better serve ‘cross racers who demand reliable shifting in brutal conditions. The derailleurs, along with their standard pull, long pull, and hydraulic shift levers; and cassette spacer are giving cyclists an affordable and reliable – if not particularly pretty or light – alternative to Campagnolo, Shimano, and SRAM.

The folks at Gevenalle replaced the lightweight carbon Microshift cage with a smaller, rigid steel piece of their own design, and made some other secret tweaks, to make a derailleur that will best suit the relatively small gear range but huge shifting loads that differentiate cyclocross from road drivetrains. Gevenalle also claims that the FD is ideally suited to single ring chainguide use, thanks to limiter screws that allow the reinforced cage to be dialed in exactly where you want it.

Oregon Handmade Show 2013: Ahearne’s immaculate stainless touring bike, Custom XL Cycle Truck

Ahearne Stainless Steel Touring Bike

I see a lot of bikes in this line of work, and honestly, it can take a lot to really blow me away these days.  One builder has done just that this year at the Oregon Handmade Bicycle Show.  Mr. Joseph Ahearne has assembled nothing short of a masterpiece.  In fact, it was on display at the Portland Art Museum as part of a rotating exhibit during the Cyclepedia show they had.

The bike pictured above is a 26″ wheeled, breakaway touring rig constructed of polished stainless steel tubing from KVA.  Why not XCR or Reynolds 953?  Those tubesets are great for a race bike, but they are only offered in thin walled tubes that would not be well suited to a utilitarian build such as this one.  KVA however, offers a thicker walled tubeset that is perfect for a long haul rig.

The frame is fillet brazed, and it’s one of the best examples of brazing I have laid eyes on.  The fact that the is polished is really impressive,  because now everyone can see the amazing workmanship that goes into each tube joint.  The front and rear racks were custom made specifically for this bike.  The front rack is convertible as well, allowing you to run just the upper, lower, or both sections depending on what you will be carrying.  They are produced from cro-moly, as is the stem, and then the parts were chromed to match the rest of the bike.

The logo panel on the downtube is a laser cut piece if stainless that was left unpolished to stand out from the rest of the frame.  Polished stainless fenders, a custom Black Star frame bag, vintage XTR parts kit, and retroshift round out the bike.  The build took six weeks, working 10 – 12 hour days, seven days a week to completed.  Want one for your very own?  Well, it would take somewhere in the neighborhood of $25,000.  Not bad for a piece of art you can use.

Head past the break for a full gallery of this bike, plus a look at his latest cycle truck in size huge.


Introducing Project Any Road: All-City’s Mr. Pink Built for Road, Gravel, Dirt & Anywhere In Between

All-City Mr. Pink Full Bike 1

I have had my eye on the All-City lineup for a while now.  When the road oriented Mr. Pink and Spacehorse bikes dropped I knew I would own one of them.  After careful deliberation I choose the Mr. Pink.  Having always been a fan of the classic steel roadies of yesteryear, it just made sense.  Once I chose the frameset, I had the not so easy task of deciding just exactly how the build was going to come together.  In the end, the frame’s specs helped direct the build.  Thanks to the large amount of tire clearance, and a somewhat relaxed road geometry, the build turned into a go anywhere project for road, commuting, and even some cyclocross riding.

Roll on past the page break for the full build list and images…


NAHBS 2013: 611 Hits a Grandslam with Lugged MTB, Wild Cross Bike, Lightweight Roadie & 3Rensho Tribute

611 Lugged MTB

Aaron Dykstra  builds beautiful bicycles in Roanoke, VA, under the moniker Six-Eleven Bicycle Co.  In 2011, he took home the award for best track bike at NAHBS.  In 2012, another award was earned for best cyclocross bike.  While no awards came to Six-Eleven this year, personally, it was my favorite booth at the show.  Aaron brought customer bikes (save one) to the show that oozed class, performance, and beauty.

Up first is this fine example of a “lugged” mountain bike.  The customer for this ride had requested a classy looking mountain bike.  Aaron set to work designing a lugged MTB, only to find he couldn’t find lugs that worked for his application   So, he took existing lugs that he liked, cut them into three pieces and then brazed the frame and lugs together.  The desired result of classy was certainly achieved.

Past the break you get more of this bike, plus some wild paint, lightweight steel, and a sparkly purple track bike…


Found: 44 Bikes’ Handmade Gravel Road Bike & More! UPDATED

Forty Four Bikes huntsman gravel road bike handmade in the USA

44 Bikes is a small shop out of New England that builds custom steel road and mountain bikes and, in the case of the Huntsman shown here, bikes that serve a multitude of purposes.

The Huntsman is laid out to work equally well on pavement and off, for gravel or cyclocross. The build shown here is for exploring rougher stretches thanks to the splayed out bars and Retroshift brifters. The chainstays are flattened to add a bit of compliance, aided by the thinner seat tube/post spec. Once the bike is built, the headtube gets a 44 Bikes badge and the seat tube gets a special badge with your own lucky number.

UPDATE: Pricing, custom options and some prototype “fat packing” bike touring bags added to post.
