Cry of the Duralcan: Ronnie Romance’s DURALCAN S Works Stumpjumper M2

Cry of the Duralcan: Ronnie Romance’s DURALCAN S Works Stumpjumper M2

I grew up working at a Specialized shop, and learned how to mountain bike by watching Ned Overend’s Performance Mountain Biking technique VHS. While I always appreciated the refreshing ideas of small makers, I thought it advantageous for larger brands to be able to invest more in their materials and construction. This was a time when top-end bikes were made of metal, and made domestically.

Metal Matrix (M2) composite is a prime example of this. The big S sourced a 6061 alloy infused with an aluminum oxide ceramic particulate by Alcan. Say that again, backwards now. Alcan called it Duralcan, and I am proud to display their logo on my top tube—that cool typeface!

Why Didn’t We See This Ultradynamico Mars Tire Poster?

Look, we’re huge Dune fans over here and we’re patiently awaiting the movie. The interstitial space between bikes and sci-fi is rather small, so when something like this pops up, we have to share it. Bryan Buswell designed this insane stillsuit art with a Shai-Hulud cresting in the background for Ultradynamico’s Mars tires. Could this be the greatest bicycle tire ad of the 21st century?

Available in two sizes, 24 x 36″ or 13 x 19″ and printed on 100# text weight paper.

Cool Breeze in Nutmeg Country: Crust Chapter II

Sometime back in late February the event calendar for Team Brooks Cool Breeze looked like any stadium tour you’d expect for such a glamorous gaggle of athletes.  Grav’l, touring, MTB, hang gliding, street luging…. you name it, we were gonna do it.  Times were fast, relaxing, and exciting, but little did we know that even lifestyle celebrity “athletes” would have little fun in the months to come.

All Road All Day with the Reserve 35 Wheels

Let’s be honest. Wheel reviews aren’t that interesting. Modern carbon wheels only need to fulfill a few criteria. You mostly want them to disappear as your ride takes over, blurred out… I feel like we post a lot of wheel reviews and I try my hardest to not regurgitate marketing jargon or keywords that get thrown around endlessly in bike media. As a consumer, you probably only care about a few things, of which I’ll address here, while showcasing some fun and different wheel review photos on one of the most recognizable all-road bikes here on the Radavist. Let’s check out the Reserve 35 Wheels below…

Tomii Cycles Showcase: Fat Canvas for SRAM

This year was to be the first year Nao Tomii of Tomii Cycles was going to attend NAHBS. For a small builder like Nao, spending the kind of money it takes to pull a seat up to the table of the USA’s largest hand made bicycle show takes a lot of financial planning, so when NAHBS was postponed this year, Tomii Cycles wouldn’t be able to attend. Most builders display customer’s bikes at NAHBS and asking his clients to wait four more months for their bikes, especially during a pandemic was out of the question. I reached out to Nao and asked if we could display his bikes here at the Radavist, so this week, we’re doing just that…

Ronnie Romance’s Madrean Ultradynamico Country Fixed

That suntanned, SUNTOURist, king of the grandiose, the beausage factory himself, Mr. Ronnie Romance, aka Ultra Romance, really knows how to put a bicycle together, even a simple one such as a fixed gear. Yet we’re not talking a Kierin bike, those NJS-stamped sparkle machines, or even a British Path Racer. This is a bike designed specifically for a plump, rough and tumble tire, with a relaxed fit, eons past the aggressive saddle-to-bar drop bikes of yesteryear, yet somewhere in-between the monster-truck abilities of a tracklocross bike. This Madrean Fabrications ‘country fixed’ is unlike anything I’ve seen in recent memory… or maybe it’s just my old age.

Inside the Ultradynamico Pop Up at Blue Lug Kamiuma

After a helluva a time getting through all the Tsunami craziness at Grinduro Japan this past fall me and the Salsa crew finally got back to Tokyo.  The rest of the posse had to take off around 4 am the next day, leaving me with about half a day in Tokyo to myself! Bené and Patrick had invited me to swing by Blue Lug for a pop up they were having to showcase there oh so éspecial new Ultradynamico Tyres. Having seen the amazing custom builds coming out of the shop for years I was excited to see what the shop was about.

Ultra Romance’s Crust Lightning Bolt is Lighter than a Soft Whisper

18 lbs? 17 lbs? 16 lbs? What is weight anyway? Weight doesn’t matter but it doesn’t hurt either. Especially when your golden locks and bronze tan lines float effortlessly across white gravel roads, coating the roadside flora in a light layer of sedimentary seasoning. Dust, baby. It’s good for you. Yes, Ronnie Romance knows how to build a bike from a fine assortment of vintage components, exotic, supple rubber, and a bit of suntan oil. Case in point, his Crust Bikes Lightning Bolt is lighter than a soft whisper.
