Ambi’s 622 SLX

This is Ambi’s new 622 SLX with integrated seat post (ISP), 44mm headtube, and Di2 shifting perched against a guard rail in the Marin headlands looking down over the Golden Gate Bridge and San Francisco. We built it with our friends at City Cycle.

Ambi says:

My bike is finally completed and she had her first 40+miles today up and down SF hills and the Marin Headlands, even saw family of deers too. She rides as mean as she looks, and as good, as fast…super stiff, awesome downhill, uphill, cutting corners..you name it! That over-sized head tube looks insane!

Effortless! Now i need to be in shape all the time to keep up with this bike.

Thanks again for all your help and please thank Jordan and all Seven crew who helped made my dream bike. Can’t wait to ride again. You guys are awesome! I am eyeing a Ti Axiom or Cafe Racer in the future. But in the meantime this bike is so awesome!

Crossing Categories

In the beginning (1997) we were known as builders of custom road and mountain bikes, and certainly of the more than 25,000 frames we’ve turned out, many of them fit neatly into one of these two categories. But as we’ve gone along, we’ve expanded our line to include more models than any other custom builder. Today we build cyclocross race and adventure bikes, urban commuters, track bikes and tandems.

Another thing that has happened is that the basic constraints of traditional categories have broken down, so that today, even though we are still building traditional road and mountain bikes, a very high percentage of our work is on bikes that cross categories or even combine them. Cyclocross race bikes that convert to bad weather commuters are common. Road bikes that convert easily for touring. Monster cross machines.

What our riders are beginning to understand is that a custom bike can be designed to serve multiple purposes simply by incorporating some features not commonly available on production bikes. Often, when they are thinking of buying two bikes for two different aspects of their cycling life, we can build them just one.

Categorization can be a good way to understand a bike’s basic functionality, but it can also be a constraint, and when you’re in the business of building dream bikes, no one wants to be constrained. That’s why we do what we do.

Melinda’s 650C Axiom S

This is Melinda’s brand new 650c Axiom S. We built it in partnership with our friends at Podium Multisport in Atlanta. The challenge here was to find a good, balanced design and fit for Melinda, who is both diminutive in stature and aggressive in riding style. Working around a 650c wheel size, Podium gave us positionals to work from, and we came up with this bike, which seems to be just what Melinda was looking for…

She reports:

My first real ride didn’t occur until yesterday! We went about 53 miles, and I honestly didn’t know what to expect. Here is my first impression: All the the ‘hot spots’ where I felt uncomfortable on my other bike were nonexistant..The pinch at the ankles, tweak in the knee, hip; ache in the back, etc….all gone. It felt like I could be on the bike and actually relax my entire body. Like sitting in a “stressless” chair (if you know what those are).

From a power perspective, on my old bike I always felt that I couldn’t pull up on the pedal stroke efficiently and I was correct! I was missing about half my power in the stroke because I couldn’t get the pull. On this bike I felt like I could utilize muscles and power that I never had access to. Rather than feeling the crunch at mile 20 and hanging off the back and thinking I couldn’t possibly go another 30+miles, I stayed toward the front most of the time, was able to fly up the hills, and even had energy left over at the end of the ride. It was beyond anything that I could have imagined!

Needless to say, I am pleased! I felt the road but not all of the bad things that come from the road like uncomfortable bumps, etc. It absorbed those nicely. It was incredibly responsive and ZIPPY! There is no better term for it! I don’t think Alan is very happy though because I smoked him up the big hills and had to hold back to fetch his sorry ass at the end of the ride. Oh well, can’t please them all!

The Next Generation

Every year, for more than a decade now, Neil Mansfield – a very longtime friend of Seven –brings his metal working students from Assabet Valley Technical School for a day in our shop. At this point, Neil can usually conjure up stories about the start of Seven and his old friends here better than we can.

A group of about 20 13-15 year-olds joined us for a Q&A with shop manager Matt O’Keefe, lead welder Tim Delaney, head machinist Skip Brown, and our graphic designer Skunk who talked about the intersection between welding and art. We followed that with an extensive factory tour.

It’s always a joy for us to see young people getting excited and curious about what we do. Hearing Neil talk to his students about a possible future where you can have a job that allows you to work in a field creating something you love reminds us that we are doing something not everyone gets to do.

Titanium/Carbon Mixes – The Best of Both Worlds

If you were to take a carbon fiber tube and wrap it against the wall, then hold your ear to it, there would be little if any sound emanating from the tube. If you did the same test with metal, it would sing like a tuning fork. The same holds true for frames, metal sings and carbon whispers. These two qualities make for very different experiences on the road. Carbon bikes, like our Diamas line, make pitted and potholed roads feel like you are pedaling over wall to wall carpeting; smooth, with very little feedback. Metal bikes, like the Axiom, Resolute, Sola, and Mudhoney, on the other hand, provide constant feedback keeping you in tune with the surface of the road. Once we start customizing and manipulating tube sets, we can alter how compliant or how stout the frames will be, but the material dictates how the road’s vibrations will be relayed to the rider.

There is a gap between whispering and singing, and to some, that’s where the perfect bike resides. By adding carbon tubes to a titanium frame, or vice versa, we can fabricate a bike that hums, bridging the gap between the two materials.

The idea of a titanium frame paired with carbon seat stays for the intended purpose of soaking up road vibrations was a notion that Seven pioneered and first implemented with the Odonata back in 1997, and though there have been some updates and improvements the same basic model exists today, now known as the Elium SL.

The ride of a ti/carbon bike is so pleasant, that we offer them in road, cross, and mountain bike disciplines.
