U.S. Built Custom Bicycles in Titanium and Titanium-Carbon Mix

Crafting Carbon

We have covered steel and titanium in recent posts. Now it’s time to talk carbon fiber.

Our approach to carbon fiber is fundamentally different than the one taken by most production bike builders, who focus primarily on the lightness and stiffness of carbon. While those are both positive characteristics of the material, we believe, in any rider-specific bike, they have to be balanced against the needs for the bike to fit properly, handle well and last a lifetime.

Though we are sometimes perceived as exclusively a Ti frame builder, we are working with carbon fiber every single day and have been for many years. We have, at this point, built thousands of custom carbon and Ti/carbon mix frames. Carbon fiber is a material we value highly for its aforementioned lightness and stiffness, but also for its natural vibration dampening characteristics. So whether we’re building an all carbon Diamas, or a mixed material machine like the 622 SLX, we always focus on why carbon belongs in the design, and then work to maximize its benefits.

There are two basic types of carbon tubing that we work with. One is round carbon tubes, like the ones we use in our Elium line, the 622 SLX and the Mudhoney PRO. These tubes are built to our specifications for diameter and wall thickness. By mixing and matching a wide array of round carbon tubes, and mating them to titanium lugs, we can tune the stiffness and handling characteristics of mixed material bikes in much the same way we do with our all Ti frames.

The other type of carbon tubing in heavy use at Seven is shaped. Just as we have an array of round carbon tubing, we also keep a significant selection of shaped tubes on hand for use in our A6 carbon line. While the outside diameter and appearance of the tubes remains constant from model to model, the wall thickness varies, altering the performance characteristics of each tube.  Cut, mitered, wrapped and bonded in house, our shaped A6 tubes give us complete customizability of fit, handling, and road feel (within the range of possibility for carbon).

Belgianwerkx – Signature Mudhoney Cross Racer

New Seven partner shop, Belgianwerkx in Mequon, WI (just north of Milwaukee), wanted to do something special for their first floor demo bike. We think they succeeded. A steel Mudhoney, painted in their colors with Belgian flag accents, new HED Belgium rims, Cannondale crank, ENVE cockpit, the works. Nick Moroder, shop manager, said, “The handling is spot-on. SO responsive. And it’s unbelievably stiff for any bike, let alone just steel.”

Grand Prix of Gloucester Cyclocross

Finally, some mud. Also known as the New England World Championships, the GP of Gloucester is part of “holy week” in our local cross world, and this year we had what some might call perfect cross weather, gray and drizzly and a little bit raw.

The Grand Prix of Gloucester is considered one of America’s best cyclocross races, and it was well attended by riders and racers from all of the country and the globe. For Seven Cycles this is a hometown event and our bikes could be found in nearly every race category throughout the weekend. From factory employees in the amateur categories to our sponsored professionals in the men’s and women’s UCI Elites, our Mudhoney’s were ridden hard and fast through the perfectly wet and muddy conditions featured in Gloucester this weekend.

Grand Prix of Gloucester CX Racing

The course was classic Gloucester; it opens with an uphill stretch of pavement through the start/finish, winds up past the beer garden steps and then dives down into muddy off-camber chicanes.  There were barriers (of course) and wide-open power sections through the grass.  Gloucester has one of the steepest and meanest loamy rocky run-ups in cross where anyone who is really running is a lot fitter than me.  There were deep mud holes and ever-changing slippery lines twisting through the trees, and day two featured a sand section that crosses the oceanfront beach at Stage Fort Park.  Spectators could watch the race and catch some amazing views of this classic New England seaport from atop a giant rock – a prominent feature in the park and a major attraction for the young ones in the crowd.

The UCI Elite women’s race featured no less than four women racing on our bikes – nearly ten percent of the field and three of them were top-ten finishers this weekend.  Mary McConneloug posted 5th and 8th place finishes, and Mo Bruno Roy was 11th and 4th.  Overall this was an outstanding weekend of racing for Seven Cycles.

Midnight Ride of Cyclocross

Last night Jake and I left work a bit early and headed west to Lancaster to compete in the Midnight Ride of Cyclocross.  This fast and fun mid-week race is in its second season and after hearing the rave reviews from last year I put it on my calendar as “can’t miss.” The Midnight Ride follows a similar course to November’s MRC race, but in the reverse direction. Since it’s still September, the course was dry and fast and the reverse direction offers less climbing and off camber turning than it’s November counterpart. Announcer Richard Fries was on hand for the event, which always makes things more exciting, and as he repeated multiple times throughout the evening, this race is the kickoff to what is now known in New England cross as “Holy Week.”

Racing as a beginner amateur and working at Seven, I’m in a great position for success. I have friendly relationships with some top Pro racers who have raced on the very same courses that I now compete on and they willingly offer up advice on things like tire selection. I ran into Mike Broderick and Mary McConneloug at Cross-Vegas last week and Mike gave me some tips on what to run for the Holy Week races. I heeded his advice and it paid off in spades. The treads that I had chosen were fast on the gravel and pavement and hooked up just well enough in the grass and loose loamy corners that I was able to walk that fine line that exists between speed and control. Line selection, not tire selection, would be the only fault in my race.

I’ve raced enough at this point that I am starting to get first row call-up and for this race I lined up one spot from the outside with a clear view of the first turn a few hundred yards ahead. At the whistle I jumped out in front and my first four of five pedal strokes put me out in front with a fair gap on the field. I had taken the hole shot, and it was suddenly my race to lose.

Having never been in this position before in any sort of bike race, I did my best to stay calm and just rode my ass off.  From what I’ve been told I actually put a sizable gap on the field and held it until my worst case scenario presented itself – a crash in a hard 180 degree turn on loose gravel. I got up faster than imaginable and got back on the bike, but after a couple more turns I lost the lead.

As we wove through the course and over the barriers I held onto second position for dear life and started to hear Richard announcing that the 14-year-old in the group was gaining on the leaders. I held second place for about a lap until the leader missed a turn in the woodchips and slid out – I was back in front.  For the next two laps I led this group of men and boys through the twists and turns of the Midnight Ride course and listened to Richard’ words about what it might mean to our egos to lose to a 14 year old.

He also seemed to give Jake’s single-speed a shout out every time he passed through the start finish area. When I finally saw the lead slip away for good, it was a newbie to cross, not a kid whose brothers have been notorious for cleaning up in the men’s field as juniors, who took it away from me.  I kept fighting and rode most of the last three laps in the 5th position and watched another young and new-to-cross racer, who had fought from the back row past about 65 other riders to take the lead with two to go.

When he went by the leaders he rode off in front with ease at a pace that none of us could match. I was cooked, and hanging on by a thread, dry mouth, blurred vision, etc., when I heard a friend yell “Joe!  Hurt!” Oh, yeah, I thought, this is not supposed to be easy, you have to hurt to win, there are no two ways about it. I kicked it back in but unknowingly was making it easy for the rider behind me. He was drafting me around the course and saving energy for a move in the last grass section before the pavement to the finish.

I feared if I let him around me so that we could work together that I would not be able to hang on, so my best bet was to keep him behind. It seemed to work, but in the end he made a move and went around me just as we came up on that speedy young teen who had finally run out of gas with just a few turns to go.

The result of these place changes left me squarely in 5th place, another top 5 finish in what has been a great start to my season.  A few more like this and the heckles along the course, hopefully, will be encouraging me to “cat up” into the 3’s, a place where many a family man can spend the bulk of his bike racing career.

Post-race, Jake and I grabbed a beer and heckled some friends as they suffered much in the same way that we just had, and then cheered on Mo Bruno Roy as she rocketed around this drag strip with apparent ease.  I picked up some tire tips from her husband and pit crew, Matt Roy, and he showed me some new treads that they are trying out for this season. It’s good to be an amateur, it’s great to get the inside line on tech tips from the pros, and it’s amazing to have the opportunity to ride and race on a bike that is just like the pros race yet uniquely built for me.
