2017 Philly Bike Expo: Engin Cycles Ti Mountain Hardtail – Jarrod Bunk

2017 Philly Bike Expo: Engin Cycles Ti Mountain Hardtail

Drew from Engin is a framebuilding prodigy, a master of the chainstay yoke and arguably, the maker of the finest mountain bikes in the USA, perhaps the world. His advances in mountain bike design have spiked the well of the industry, pushing the envelope of geometry and detailing. All of this is ATMO, of course, but having been a longtime dan of Drew’s work, it’s amazing to see how flawlessly he’s adapted to the changing and sometimes harsh ecosystem of the cycling industry.

Drew designs, prototypes and machines his own yokes and dropouts from titanium. He then welds them together for a beautiful frame with a unique bottom bracket cluster that allows for the use of a standard q-factor crank. It’s easy to overlook these details, even on such a simple frame, yet as we’ve all heard before “God is in the details…”

Moots is one of those brands that just oozes brand clout and rightfully so. Their titanium frames are built to the highest standards and are built to last a lifetime. The Mooto X RSL is designed with speed in mind. A true singletrack slayer, the Mooto X RSL has a modern race geometry, with the feel of titanium, designed to tackle any XC course.

At this year’s Philly Bike Expo, Moots brought their catalog build of the newest Mooto X RSL, laced with gold Tune components, matching logos and Shimano XTR Di2, this bike relies on its pedigree, in a sea of flashy show bikes.

Firefly Bicycles: Magenta + Cyan

I’m not sure what the story is behind these two frames are, but I hope there’s a gold one on the way, to complete the primary colors. Or it could be a his and her combination, but whatever it is, they look stunning. Check out more at the Firefly Tumblr.

Chumba’s Made in Texas Terlingua All Road Bike

Named after a West Texas ghost town, the Terlingua, gets its namesake for the ability to traverse multiple road surface in this rugged part of the American West. Home of the Chihuahuan Desert Dirt Fest, the team at Chumba have fallen in love with riding there and wanted to design a bike that would be capable enough to handle the terrain, without compromising ride quality, or functionality. The Terlingua is a road bike, with large clearances, fit for dirt road riding, bikepacking and even ‘cross races. These frames are made outside of Austin, Texas and have all the boxes checked in terms of adaptability, they’ll fit a 700x50mm or 27.5″ equivalent, come in a variety of colors and pricing begins at $1450 for a frame. Check out all the details below and see more photos at Chumba!

2017 Philly Bike Expo: Weaver Cycle Works Jersey Devil Gravel Bike – Jarrod Bunk

2017 Philly Bike Expo: Weaver Cycle Works Jersey Devil Gravel Bike
Words and photos by Jarrod Bunk

Hailing from South of Jersey, Weaver Cycle Works, made their way out to PBE with this Jersey Devil themed bike.  The Jersey Devil is a mythical creature that can take down livestock, much in the way that this 47c equipped bike can tackle the varying terrain that it was designed around. The Jen Green head badge pulls the theme together along with the “13” which is for the cursed 13th Leed’s child (the Jersey Devil).

Built with a 1x drivetrain in mind this SRAM Force-equipped bike is propelled forward with a blend of White Industries R30 cranks, CLD hubs, and their new headset, and halted just as quickly by Paul Component Klampers.  This is Weaver’s personal bike, and I’ve been told he only rides steel forks, so even though it’s built with a 44mm headtube, there will not be carbon on it anytime soon for him.  Much like every Weaver this bike is 100% custom from the geo to the paint, if you’re into it, drop him a line and you to can rip a bike where the devil is in the details.

Richard Sachs Seat Lug Survival Kit

Details matter. Especially on a bicycle. From the cable stops to even the seat binder bolt. If anyone knows about this, it’s Richard Sachs:

“The RS Seat Lug Bolt and Nut are precision machined from aerospace grade stainless steel solid bar stock. The pitch diameter of the bolt was held to a super precise tolerance prior to cold forming on dedicated thread rolling equipment. Rolled threads result in a part that is 30% stronger and has a superior surface finish. The care put into this one component demonstrates that whether you are making parts for airplanes, or for bicycles, the details matter.”

Swoop this setup at Richard Sachs or for more on the project from Horst Engineering, the Connecticut firm that made these, read this page.

2017 Philly Bike Expo: Walk the Floor and Meet the Builders – Brad Quartuccio

2017 Philly Bike Expo: Walk the Floor and Meet the Builders
Photos by Brad Quartuccio, words by John Watson

Over the years, the Philly Bike Expo has grown to become the Northeast’s premiere bicycle gathering, bringing together frame builders and independent companies alike. This pairing makes for a weekend that not only draws in foot traffic from the streets of Philadelphia but cycling enthusiasts from all over the United States. Most importantly, the Philly Bike Expo is put on by the great Bilenky family, whose main motivation is to unite the scene in a fun, energetic environment and it shows.

Photographer Brad Quartuccio was hired this year to document the show, the bikes and the builders who make this event truly unique. Brad was kind enough to share this wonderful bounty of images, which I’m very excited to share here on the Radavist. After seeing these portraits on his Instagram, I hoped to be able to display them in high-res.

It’s been a while since I’ve attended the show, which falls during a particularly busy time of year for me but after seeing both Jarrod and Brad’s photos, makes me want to book my flight well in advance.

2017 Philly Bike Expo: No 22 Bikes Stock Complete – Drifter

2017 Philly Bike Expo: No 22 Bikes Stock Complete – Drifter
Photos by Jarrod Bunk, words by John Watson

For those looking for a stock-sized, titanium, made in the USA frame, check out No 22’s latest offering: complete bikes in two weeks. Since 2014, No 22 have been building ti frames in their Johnstown, NY factory and now, you don’t have to wait months for one of these frames. No 22 is offering up frames where no detail has been spared, no corner has been cut, with the only difference being the 8-10 week waiting period has been shorted to two, and as a complete build.

These completes utilize a No. 22 full carbon fork and aluminum stem, both custom painted by Velocolour, No. 22 titanium seatpost, custom finished to match each frame, Complete Ultegra 8000 groupset with mechanical shifting, Reynolds carbon tubeless wheels and Schwalbe tubeless tires and a high five. I added in that last part. The models available are the Great Divide in raw finish for USD $5,999, Great Divide Disc in raw finish for USD $6,799, or the Drifter in raw finish for $6,799.

If you want your No 22 anodized, they do that in house. For paint, they go to Velocolour. Each of their bikes are available in a choice of raw or two different anodized finishes, with the fork, stem and their new titanium seatpost finished to match.

If you’ve got questions, send them to No 22 or drop them in the comments.

Kris at 44 Bikes Explains Superboost’s Benefits for Hardtail MTB Frames


Photos by Jarrod Bunk

135mm, 142mm, boost and now “super” boost. What gives with all these rear hub standards? I just wanna shreddd! Well, Kris from 44 Bikes knows a thing or two about shredding and frame design, so he tackled explaining superboost in his latest blog post:

“Earlier in the year, I put together a post just after completing the next iteration of the Marauder in a titanium prototype. You can read that post here. What is special about this bike is I used the pre-existing 157mm TA standard paired with an 83mm shell width. This is technically an existing DH standard which Pivot tweaked by adjusting the flange spacing of the non-drive side to move it outboard a bit more to stiffen up the rear wheel build and subsequently re-marketing it as “Superboost”. Which I think took some by surprise as a “new” standard. It’s quite the contrary. And when paired with that 83mm shell width (another existing standard) you get perfect chain line and a critical area of the bicycle is literally opened up to so many opportunities as tires gain more volume and width. ”

Win a DreamSalvo NAHBS Bike

Want to win a FREE NAHBS bike built by Mike Desalvo? Check out this contest’s information and rules below!

“At the close of the NAHBS show last year I was talking with an industry friend and the question is always “will you be going to the show next year?” My thought was that I would go if I could take just one bike. The 2018 NAHBS is a distance from me and shipping a lot of bikes and show stuff is hard and expensive for a one-man operation. After the conversation I liked the idea of just taking one bike but then the question was, “what will I take?” This is how this how the dream bike contest came to be.” (more…)
