2018 is an exciting year for us. For the past 8 years, we have designed framesets and components, and in partnership with Cinelli, had the opportunity of distributing them to riders around the world. As the years went on, it became clear to us that we wanted to manage it all, and the experience has been invigorating.  For the first time, we are creating and manufacturing these designs independently as MASH, and shaping the designs with every detail we envision in an object. The first frameset offering is our SS Steel design. Born as an all-arounder with racers, workers and commuters in mind, this Columbus steel frameset was developed.  As an aggressive SSCX geometry or a well handling track bike, our frame designs are historically aggressive. This one splits the difference by being comfortable with a front rack loaded, tracking well in the dirt, while still responsive on the city streets. PRE-ORDER HERE

Details include:

  • Columbus Cromor Double Butted Tubing
  • Straight blade fork with 35mm rake
  • 1 1/8 threadless headset (not included)
  • 27.2 Seat Post
  • 30.0 seat collar with cable hanger
  • 100/120 track hub spacing
  • BSA english 68 bottom bracket
  • Two water bottle mounts
  • Removable Brake Studs
  • Internal rear brake cable routing
  • Clears most 38c tires
  • Frame and fork weight: 2900 grams
  • Includes nylon plugs to fill brake holes if needed
  • Top cap, bolt, and star nut included

Frames are built with Columbus Cromor triple butted steel tubing. We love the balance of strength to weight for this set.The Black Chrome finish of the frame is fully chrome plated then coated with a black clear. Over time these painted frames can chip to chrome like many of the classic Italian road bikes. The downtube and rear dropouts are a window to this layer.We offer 5 sizes with subtle geometry updates based on three years of development and testing in the dirt and on streets.Framesets include a removable seat collar and rear cable guide if set up with cantilever brakes.

The silver smoke finish draws inspiration from paint techniques of the early 90’s. This metallic silver base with smoke contrast creates a beautiful finish with white artwork on drive-side, and black on the non-drive.Each frame includes the top cap for 1 1/8 threadless stems, the bolt, and star nut.These frames have removable brake studs and internal cable routing. You can run them as lean brakeless street bikes, or set them up with brake options for canti or mini-v options for racing or commuting.The fork includes a brake hole that can be used for mounting a rack, fenders, or long reach caliper. 

Our pre-order for both finishes of this frameset are available today, and will begin shipping worldwide at the end of March.  If you are in Japan, you can pre-order both designs from Blue Lug in Tokyo. If you are in New York, you will be able to get frames and components from Deluxe Cycles. We do not have any additional dealers at this time, but hope to offer frames to a few new shops as we grow.


Look for new designs in 2018 including front racks, riser bars in alloy and carbon, and toe clips, as well as collaboration projects with Izumi and MKS this spring. We will continue to offer additional frame designs including an aluminum/carbon track frameset this fall.

Thank you for riding with us as we embark on this next journey!

NACCC 2017 & Pre-Event


70650027PRE RIDE

The summer is as always an exciting time, work slows down, people find themselves with some free time, and everyone can make some excuses to skip town for a bit. This year two of my favorite events – Minneapolis’s “All City Championships” and The North American Cycle Courier Championships coincided within the same two weeks in the blissful late august Midwest. We arrived to mpls on a thursday built our bikes up and started what would turn out to be a pretty wild trip. ACC consists of 3 days of events – SK After dark (alleycat) Bike Jerks Bandit Cx and the Main Shindig on Saturday. Being the pre-event for NACCC many people were brought to mpls for their first time, and once seeing how those fools got down they will likely make it a yearly stop just like myself. After the weekend of events, the few if any hours of sleep, and stupid inside jokes already making the rounds through the group – about 20 of us geared up and started the Pre- ride to Milwaukee, WI which would be a 4 day 3 night 380mi~ adventure through the middle of Wisconsin. A few of us had done the reverse of this ride a few years back when the NACCC was in MPLS, and woah what a trip it was retracing our steps 3 years later. The scenery of WI is Beautiful- rolling hills for days, cows, bluffs, tunnels, and my favorite the rails to trail. Jeff Oneil did a fantastic job routing us and keeping the group together oh and of course telling us how many mile to go every 5 min. We finally rolled into Milwuakee and were greeted by everyone at Cafe with free beers and friends.  Turns out that same weekended was the Harley Davidson 115th anniversary so the streets of Mke were swarmed with two wheel Vehicles of all sorts, it was rad. After a long ride no way better to sooth the tired muscles with  an out of towner alleycat and Karaoke party which is exactly what we did.  The NACCC organizers somehow scored an entire elementary school campus to use as the course for the main race which we spent many an hour at over the next few days. Siting atop a small hill in the Hay-market district, they provided a challenging course with elevation sharp turns gravel and alley ways. By far my favorite course to date.

Just wanna say thanksthanksthanks to all of the Organizers for giving us one hell of a Mess vacation and congrats to Allan Shaw for taking home the NACCC overall win, against all odds we could say.  I wish i had the words to describe how fuckin’ insane and fun the whole trip was but I just can’t, guess you’ll just have to see for yourself…


ACC 12



















































MASH3189An email message can lead to nothing or something. One was from an old friend, Yohei Hanazwa, who produces crazy events in Japan now. You might remember him from the friends chapter of our 2007 video. He let us know that official Keirin had tracked him down and asked if he knew how to get in touch with MASH. To promote the 2020 Olympics coming to Japan, Keirin was organizing a large event at the Izu velodrome, inviting national and international racers to compete and wanted to invite us. Incredible! Track Party was a one day event that encompassed a fixed criterium, a box jump demo,  a flatland demo, live music, comedians as announcers, gold sprints, vendors, and a ton of track racing. Enclosed are details from this special time in Japan getting hyped on bikes.


The Izu velodrome is a magnificent structure. Modern indoor tracks come at a steep cost, but are a requirement for a nation applying to host the Olympic games. The Izu velodrome is five years new and is perfect. It is built on a cycling campus that includes multiple velodromes and a Keirin school, which hosts training and racing for the state and national level teams. Programs like this are crucial for the future of this sport community.

It was a massive rush to be invited to race on this Olympic level velodrome. MASH was born on the street, helping adopt bikes intended for velodrome use and contributing to the fluidity they bring to the streets. Over the past 12 years, the velodrome has been a part of our community, but admittedly, a smaller piece than other cycling formats. It could be location, with the closest track an hour away by car, but a core group from SF have made the pilgrimage year after year to train and race at Hellyer.

Ever wonder what those high speed cameras that record photo finishes look like?

Track racing has been part of the Olympic games for 120 years and with the rise of urban cycling feeding into fixed gear criteriums, there has not been a spike in track cycling that reflects the rise of the bikes born from the velodrome.

Happy to have been able to bring Duke on this trip. He raced, explored, soaked, and ate some new stuff.
MASH2024Outside the velodrome, several events, displays, vendor tents, and a fixed criterium all happened in the rain.

The women’s Keirin racing program is growing in Japan. It still feels a bit sexualized, but we hope to see this component mature in the coming years.

Who’s ready to go back inside?

Traveling around the world to race bikes is an incredible opportunity. Rainier and Chas have found themselves in so many inspiring moments together over the years, and this trip was one of them.

Qualifiers required putting in a fast lap. Sub 10 second laps transferred you to the main events.

Ultra-high-performance sports speak less and less to the new generation, and this is a concern for its organizers. A skateboarder has a low buy-in to their sport. They can roll around in the area they live and progress. Cycling has a more expensive entry that can come easier to some. Velodromes can offer youth programs and loaner equipment to help those who show potential, but do not facilitate a support system that can fund the required commitment and expenses. The facility and the equipment seem to be limiters for growth to the sport.MASH3801




This Derny had a live camera feed to the projection screens offering a live view of the first few laps in some of the events.MASH3314

Theo Bos is really fast.

Like a skate park, a velodrome can be a community center – a place where those interested can meet, share ideas, train, learn and race together. This trip was challenging to digest as a high performance sport. It felt like the future of these spaces and this level of competition could be less exclusive – opening these spaces to after school programs, maybe using the infields for mixed use like skate parks.

This is Yohei, you might know him from the friends section of a video we released in 2007. He is an event organizer in Japan, and helped bring us on this trip. Thank you for helping make it happen!MASH2928

The equipment can make a difference. If you are fast, you simply are. When the races come down to a fraction of a second, the technology matters. A $7,000.00 wheelset makes a difference at the line, and the list goes on. The clothing can shave as much time as the bike and when you are defining winning and losing by a fraction of time, it all adds up.MASH3969

DFL 3 2017

MASH0402DFL is a longstanding tradition in San Francisco. This group of friends have organized underground cyclocross races in the Bay for 23 years and have helped shape the community here, no question. As members grow and have families of their own, the turnout is a mix of new racers learning about these traditions, racing side-by-side with the founding members of the hush-hush race series. It is perfect.
MASH0298The following moments capture the energy and spirit of the series, found by word-of-mouth, on a week night in an empty park, Hunters Point, SF CA.

MASH4857With the third stop of the 2017 Red Hook Criterium series in the books, we take a moment to look back at the details from Barcelona, Spain.  MASH3949With a solid six years of racing this series as a team, we have a good understanding of what to expect. International travel includes packing smart and light, remembering the power adapters, snacks, and sleeping on couches. As a small bike shop, we never have enough support for our racers, always bare bones, no private shade tent, cooler, our own rollers, chairs, limited tools, and it always works out. We adjust to the ever-changing rules for qualifying and the press.MASH4383Duke’s custom Giro road shoes. Chas draws on his friends’ stuff, and we love the finished results.MASH3953The series is a well oiled machine with almost all details sorted out for the athletes and spectators. MASH5172Gabe is the MC for the day, offering insight to the crowd. Racers love hearing their names come through this mic with high energy.MASH4919MASH4995Wearing the red jersey marks you with the racers and the cameras. MASH4477The new qualifying format is a much safer system for the racers, which are set up as mini races with the top transferring.MASH4735Duke qualifying in group four.MASH4301Volunteers fill the course to notify racers of what to look for through a series of colored and pattered flags.MASH4264David Trimble started this series as a birthday party, with racing in his blood, he wanted to grow it to an elite event. His vision is coming to fruition with a solid budget, events running like clockwork, and over the years, has gained the attention of world class athletes, billion dollar brands, and the UCI.MASH4835MASH4752It feels good to be passionate about something. The racers are fulfilling personal goals while working for their teams and the logos they wear, and the photo/video crew have a job to tell a story, and fill obligations for publications. We are our own client, so there is no pressure to make something specific, just what is striking. MASH5250 Been all over the world with Chas and have watched him drink from every faucet and eat like a local with no effect, but the stomach bug caught up to him on race day, and he still smiled and dry-heaved his way through qualifying like a champ.MASH4160MASH4980MASH5149MASH5252Hot DogMASH5128MASH5280MASH5267These events are part bike-race and part car-show of sorts where looking is part of the day.MASH4376MASH4097MASH4346MASH5331MASH4561The concrete in corner two had a very smooth surface, and took some cornering adjustments for racers to ride it in a more conservative way.

Velòdrom d’Horta RHC 2017

MASH3920With no rain in the forecast, racers visiting Barcelona for the Red Hook Criterium met at the D’Horta Velodrome to spin legs in preparation for to tomorrow’s main event. With clouds helping keep the temperatures low, a solid group took turns putting down laps on this historic velodrome. It had been years since visiting this track, and was happy to see the remodel wearing in nice. Enclosed are a series of photos from the morning.



MASH2739Resistance Racing gathered up the crew and headed to the Port of Oakland for stop three of their Track-X series. Racers met on a warm Sunday afternoon, ate tacos, enjoyed a coffee or beer, registered, and lined up to race mostly brakeless track bikes in the sandy landfill that is the port. Enclosed are some photo details for the day. MASH2592Massive cargo ships unload fidget spinners and whatever else as a backdrop for some bike racing.MASH2602Tacos and coffee reg was so nice.
