Welds that Speak for Themselves


by Byron on Feb 29, 2016 at 8:24 PM


While assembling and editing Issue 33, I shared a few photos of a Triple Three Fab bike in a preview post here and on our Instagram. It was designed, built, and assembled for NAHBS at DKCB and a featured gallery in the issue, with commentary from Mark V. This weekend Patrick Brady noticed Max’s (the K in DKCB for Kullaway) skill too in his honorable mention post

Maxwell Kullaway, the welder at 333Fab is a former welder for Seven and Merlin. There’s no other way to really say this: it shows. The category of Best TIG Welding is rarely a contest and this year it was close. Kullaway’s work was clean and perfect in a way that many aspire to and few rarely achieve. With guys this good judging comes down to looking at each one of a bike’s welds and examining the end point for the weld. Kullaway’s work on this bike would have been an easy winner in this category were it not for the category’s eventual winner. This stood out noticeably from a truly exceptional group of entrants. These welders are better than the guys working in aerospace.

The welds speak for themselves. Read more about NAHBS on RKP and Issue 33 Crafted is available now on iTunes and the Web.

Fat Bike Winter Ascent


by Byron on Feb 26, 2016 at 10:08 AM

In the few times I’ve hung out with Tim, he’s never mentioned a desire to ascend Mt. Washington on a Fat Bike, but here he is doing it for Red Bull. Why? To do something creative and I can’t argue with that…

Getting the opportunity to do this is, first of all, fun. But it’s also challenging and creative in a sport that really is not [creative]. Cyclocross and road racing, by nature, are not creative — you’re simply trying to beat the hell out of yourself and, essentially, survive longer than the person you’re racing against. That’s it. It was really cool to experience this, and see it from a different angle than what a “bike ride” was all about for me for so many years…

In that quote, Tim also states what’s I think is going on with road and the return of adventure…it’s do more than fighting to cross a finish line first, and suffering greatly in the process.

Cyclists are also after the perfect ride, a stress-releasing mood, hitting a zen state, or they simply have, “Miles to ride and all day to get there.”

ENVE confirms GRD fork for gravel/all-road bikes


by Mark V on Feb 25, 2016 at 3:41 PM

After a low-key sneak preview at the 2015 NAHBS event, ENVE confirms full production of their carbon GRD fork just ahead of this year’s show. The first small run of forks has already been divvied out, but the next shipment is scheduled for the beginning of April.

The GRD fork is intended to serve the still growing gravel/all-road demographic. The fork uses a 12mm thru-axle, the apparent standard for “disc road” bike componentry. The full-carbon steerer tapers from 1.25” to 1.125”. The GRD also joins the flat-mount disc caliper bandwagon, though pix from last year’s show reveal that the prototype forks had post-mounts. The switch to flat-mount might explain the oddly long span between first glimpse and actual production. Rotors 140 to 160mm can be fitted.

The GRD fork is a remarkable for two reasons. Doubtlessly most people will be talking about the integrated carbon fender, which ENVE says can be removed in seconds. Among full carbon forks of this type, the ability to cleanly mount a full fender is still rare. ENVE’s proprietary fender is a full carbon affair that snaps securely in place at both the crown and dropouts. No word yet on what the consumer is supposed to use on rear of the bike. However, the less obvious but more important consideration is the GRD’s axle-to-crown measurement.

At 383mm A-C, the GRD neatly splits the distance between the 370mm of most road bikes and the 395mm virtual standard of cyclocross bikes. This means you couldn’t really retrofit the GRD to either existing road or cyclocross framesets without dramatically changing the geometry when the head tube gets boosted or dropped (on road or CX frames, respectively). Thus the GRD is designed to compliment frames designed specifically for the all-road demographic, rather than adapted from existing CX designs.

On the other hand, the “gravel scene” is far from uniform in its design preferences. With a maximum tyre clearance of 35-38mm, the GRD won’t fit the 40-45mm sizes that many insist are necessary for gnarlier gravel excursions, though that much volume is getting into the realm of 29er rubber. And such tyres wouldn’t fit under a 383mm A-C anyways. However, the ENVE fork is particularly appealing as for all-weather road bikes. I have often said that it is odd that frame designers should go to disc brakes that allow road bikes to accept any size tyre independent of the limits of short-reach rim brake calipers, and then be limited to forks that essentially still mandate tyres smaller than 28mm. The new ENVE fork steps outside the constraint of road fork design without going all the way to CX fork height, which isn’t necessary if the front wheel isn’t going to be encased in mud-n-grass from a CX course. The 47mm rake is a middle of the road dimension; it should be amenable to most designs outside of the low trail philosophy embraced by the Francophiles of Compass Bicycles.

So to whom does this fork appeal? Due to the unusual axle-to-crown height of the fork, one would have to design a frame specifically to fit this fork, and small framebuilders are the ones who can most quickly respond to the potential this fork holds. This is great news if you are now or soon to be in the market for a custom bicycle for all-road, or perhaps that high performance winter trainer.

How Mark V sent SRAM Apex1 to NAHBS


by Mark V on Feb 25, 2016 at 11:34 AM

Today all the cycling websites on the SRAM media mailing list have announced the debut of Apex1, SRAM’s new entry-level 1x drivetrain for dropbar and flatbar road/gravel bikes. But Bike Hugger is a way ahead of them because I…..Mark V, humble priest of Her Church of Immaculate Wrenches….have already installed an Apex1 group on a 333fab titanium gravel bike, which is currently in a van on the road to NAHBS. Of course, I’m sure all the product managers for the big bike companies have known about Apex1 since late 2014, because that’s how this industry works. But that’s a story for another day. For now, let me tell you about putting Apex1 onto a bike for NAHBS.

So Max Kullaway of 333fab Bicycles registered for NAHBS months ago, and somehow or another SRAM agreed to supply an Apex1 group for a 333fab to go into the SRAM display booth at NAHBS. As the buyer/assembler at the Davidson & Kullaway Custom Bicycles studio (the frameshop for 333fab and Davidson Bicycles), I usually handle all the bike kit ordering through various vendors, but this deal was brokered entirely without my knowledge. That is until I was told to send SRAM a list of individual parts for the Apex1 group. Perhaps the layperson doesn’t realize that all these big time venders work off their own in-house SKU# (typically 7 to 10 digits) on everything they sell, and I had to order a collection of items for which no one, including apparently our contacts at SRAM, had SKU numbers. But SRAM couldn’t process our order without the correct SKU#……hmmmm. I don’t know how all that played out, but Max eventually appealed to someone at SRAM who could shove that order out the door. So with two weeks before NAHBS, UPS drops off a box with red & white SRAM logos at Davidson & Kullaway.

SRAM’s Apex1 will bring the simplicity/performance of 1x11 drivetrains and the power of hydraulic disc brakes to a very attractive price point. The 11speed drivetrain incorporates the same X-Sync chainring technology as was first developed for the pioneering XX1 mountainbike drivetrain and later used in the Force1 and Rival1 road groups. Apex1 has its own crankset design with an integrated spider, differing from the modular spider designs of the more expensive groups. The 333fab bike I built for the show used a GXP-style crank, but Apex1 is also available in a BB30/PF30 design. Rather than irksome hidden fifth-bolt pattern of the higher models, Apex1 has a conventional 110mm bcd five-arm pattern. Chainrings are available in 38, 40, 42, and 44tooth sizes. Like all SRAM X-Horizon (1x specific) rear derailleurs, Apex1’s has a non-slanting parallelogram and a top pulley widely spaced from the cage pivot. Looking at the Apex1, I could see how costs were saved with less expensive details like stamped steel rather than forged aluminium, but the overall finish and construction was rather nice. The weight is reasonable compared to more expensive X-Horizon derailleurs, but frankly all of them are kinda chunky no matter how expensive. Unlike the other road X-Horizon models, Apex1 seems to be available only as a long cage, with no mention of medium cage in the press release. The other big departure from Rival1 and Force1 is the wide-range 11speed cassette. Apex1’s PG-1130 cassette is 11-42, not 10-42. This means that the Apex1 cassette does not require a hub with an XD-style cassette body. Instead, the 11-42 cassette can fit on 10sp or 11sp (with a spacer) HG-style cassette bodies, which will make it easier to fit wide-range 1x11 on bikes for both OEM product managers and aftermarket consumers. But if you really want to use a 10-42 XD cassette, don’t worry; the Apex1 can handle it. I know because I spec’ed a 10-42 XG-1150 on the 333fab bike.

The Apex1 hydro levers look identical to Rival1, and if anything I like the Apex1 graphics better. Like all of the SRAM hydraulic dropbar levers, the Apex1 has a nice lever feel. Unlike Shimano, the pads make contact with the rotor well before you exhaust all the lever throw. Shift action feels good, though all the X-Horizon rear derailleurs feel a skosh heavy due to the roller clutch. There’s also a 11sp shifter pod for flatbar bikes; in that case I guess you’d just borrow a brakeset from SRAM’s mtb line, since there are no Apex1 flatbar brake levers.

Honestly I blindly ordered the Apex1, knowing but a few vague specs and nothing about pricing until this morning. But the pricing is really good, no joke.

Cranket: $116 GXP/ $151 BB30

Rear Derailleur: $74

11sp shifter pod: $27 (say whaaaat?!)

LH dropbar brake lever: $199

RH dropbar integrated lever 11sp: $249 (okay, not super cheap, but integrated levers never are and especially not hydraulic dropbar levers. Still these are about $20-35 cheaper than I had guessed)

Cassette: $79

Chain: $14 (this is super cheap as far as 11sp chains go)

Stopped by DKCB and got a NAHBS preview. This 333 Fab whip is one of the show bikes and there’s quite a lot going on with it. I could write a book about all the details. If you’re in the Seattle area, see it at the shop or later at the show. That mouthful of acronyms?

Davidson Kullaway Custom Bikes and the North American Handmade Bicycle Show


Not into politics, so don’t know how the awards are decided, but that bike has my vote–and mostly for the do-everything design. Also, it’s handbuilt right here in Seattle.

Pivot Phoenix DH Carbon


by Byron on Feb 16, 2016 at 6:38 PM

The New Pivot Phoenix DH Carbon from Pivot Cycles on Vimeo.

So much to catch up on after a long weekend of fat biking in the Methow Valley, and we’ll start with this PR from Pivot and the edit. Rode Pivot a few years ago during a media event and here in Seattle, that’s why I share their content still – exceptionally well engineered. Also not a brand everyone else has on the trail.

Set your racing on fire. With input from the Pivot Factory racing team, the new Phoenix DH Carbon is 2/3 of a lb lighter, and offers more go-fast features than any other gravity offering on the market. In this video, rider Bernard Kerr, Eliot Jackson and Emilie Siegenthaler offer their input and feedback on what makes the new Phoenix their choice for the 2016 World Cup and Crankworx season.

Mark V reviews: BioLite PowerLight Mini


by Mark V on Feb 16, 2016 at 2:43 AM

Occasionally I happen upon an item that completely takes me by surprise. At first glance the PowerLight Mini from BioLite looks like an odd tail light masquerading as almost-vintage flip phone. BioLite is a company that is perhaps better known for making clever devices such as a camp stove that smokelessly burns wood to generate heat for cooking while simultaneously providing electricity to charge a phone, GoPro, or other electronic device. I thought so they’re making a bicycle tail light, ho hum. It turns out that the PowerLight Mini is so much more than just that.

The 80gr PowerLight Mini is 80x51x15mm. You can choose to run the light as either red or white LED, with about 4/5ths of the face lighting up. Theoretically you could use the PowerLight Mini as a headlight on a bike, as the included mounting bracket allows the light to be mounted either parallel to a tubular structure (as a tail light on a seatpost) or perpendicular (as you would on a handlebar), but the PowerLight Mini’s light is not really designed to project a concentrated beam a great distance away. Instead the face’s array lights up as a glowing source of evenly diffused light. Of course, that works just fine for a tail light when set to red LED, but that white light works great for a variety of situations off the bike. Since it produces a broad light pattern with no hotspots, it works nicely as miniature work light or camp lantern. The wire clip that at first seemed like an odd manner of attaching the PowerLight Mini to the mounting bracket, turns out to double as a flip stand, so you can set the PowerLIght Mini down. You can also use the clip to affix the light to your clothing, like on your chest if you needed to do detailed work with your hands. You can even use the light in red mode if you want to maintain your night vision. If you’ve ever tried to change a flat in the darkness of winter, you can well imagine how useful this light is. Usually when you try to use the typical bike light for the same task, you blind yourself looking at the hotspot from the beam and then can’t see anything unless you shine that hotspot directly on the target. As a lantern on hi setting, it will give 5hours of 135lumen light; in strobe it should give up to 52hours.

I was so delighted over those features above that I almost forgot that the significance of the “power” in the PowerLight Mini moniker. The BioLite product also functions as a 1350mAh power source for personal electronic devices. It has a mini-USB port for power in, and USB port for output.

The $45 PowerLite Mini is new for Spring 2016. You can pre-order now; shipments begin February 16th.
