Seven Cycles

Two weeks ago, when loading my beloved singlespeed Seven Sola 29SL into the trailer prior to the Hop Brook Dam Mountain Bike Race, I noticed that the top tube was cracked. It was a bummer and I missed the race. We still went to Middlebury, CT because our son did the Junior race.

I hadn’t ridden that bike since the prior Monday at the Dirty Duathlon in Glastonbury, CT. It’s possible that the crack appeared before that ride, but it certainly got worse on the bumpy course at the Longo Preserve.

I wrote about this bike in 2012, though I’ve been racing it hard since 2011. It is made from Titanium, and the crack went from 11:00 A.M. to 1:00 P.M. so the top tube was nearly severed. It would have been ugly, if  it came apart while riding. The crack started at the bottom of the weld and worked its way in both directions.

Titanium failures are rare, but they do occur. Usually, the root cause was a bad weld. One of the benefits of a raw Titanium frame is that it can be repaired. I reached out to the team at Seven Cycles in Watertown, MA. They came up with a game plan and I dropped it off the next day. Fortunately, I had to be at Sterling Machine in Lynn on Tuesday, so the timing was good. We work with Titanium all of the time, but not tubing. Our raw material is solid bar stock and plate. Also, we don’t weld it. Our experience with the strong (but light) metal is exclusively with machining, grinding, and thread rolling.

One week later, I picked up the repaired bike, and it looked like new. They couldn’t match the decals perfectly, but that is minor considering the extent of the repair. They completely disassembled the bike. They cut off the top tube. They cut the down tube away from the head tube. They replaced the head tube and the top tube. Finally, they re-finished the frame, and rebuilt it with all of the parts.

They did the best they could to tune the Gates Carbon Belt drivetrain, but it still needs some work. It’s too bad because I had the tension of the belt dialed in perfectly, and it hadn’t slipped in five years. After I picked up the bike, I drove over to the Middlesex Fells to test itout. Unfortunately, the belt is slipping on steep climbs, so we have some tuning to do.

The fact that they repaired the frame is fantastic. I’m glad this frame didn’t end up in the scrap bin. All of my Seven’s are “lifetime” bikes. Kudos to everyone involved with the repair. Despite needing to do more tweaking with the set-up, I’m pleased with the outcome, considering that two weeks ago, this bike was unrideable.

I raced the bike today at the Fat Tire Classic in Farmington, CT.

@thecubscouts #pinewoodderby never gets old. Pack 157 Bolton, Connecticut #cubscouts So that little injury caused by my @renocxnats crash on Saturday afternoon wasn’t so little after all. It’s a broken leg (fibula). Prognosis is good, but it hurts like heck. My blog post report with blow by blow details is linked in my profile. #cxnats #teamhorstsports @horsteng #crossspikes #crossisboss - - -

This #lifedeathcyclocross stuff is true!!!! I crashed out of the Singlespeed Championship @renocxnats (on the dreaded off-camber) but not before having more fun. @artroti43 raced on the frosty course ❄️ at day break. 🚴🏽 We met a lot more @horsteng #crossspikes customers. I hung with little bunny hopper 🐰 Miles, the Junior 11-12 year old Silver Medalist.🥈I cheered for Nic, who represented @the_ccap in the Junior 15-16 age group. @sportstert and Iva came down from Tahoe to cheer LOUDLY for me. 🎺 I got my badly sprained ankle taped and iced. I had a beer. 🍺 I’m even looking forward to my red eye flight home ✈️ . Best of all, I’ll see @trailrunningmom and the kids on Sunday. I can’t explain the sensation, but despite the pain, I’m ready for next #Cyclocross season to begin... after some rest. #teamhorstsports #cxnats #horstengineering @parkavebikeshop #crossisboss #lifedeathcyclocross #crossiscoming You could say that at least for this week, I’m married to my #bicycle - - -

@renocxnats #cxnats @seven_cycles #sevencycles #teamhorstsports #horstengineering #crossspikes @horsteng #chapelofthebells #Cyclocross #lifedeathcyclocross Good day representing @horsteng at @renocxnats in the 45-49 age group. It’s a great course. The wind was blowing hard, but the sun finally came out. I’m happy with 37th place but should have made a move to get to 29th, which was 30 seconds ahead. That’s a long way when you are going flat out and cramping. 4,500 foot elevation was a factor. I’m disappointed that they cut one lap of my race when I wasn’t close to getting lapped by the leaders. You train this hard and come all this way; and you want to get the most racing for the $ and time invested. They only let 25 riders do the full six laps. The only positive to come out of that was that I watched fellow New Englander @adammyerson execute a perfect final sprint to win the Stars and Stripes again. Teammate @artroti43 had a good ride too. 
@seven_cycles #sevencycles #horstengineering #teamhorstsports @bicycleseastct #crossspikes #cxnats #renocxnats #Cyclocross #crossisboss @therichardsachs didn’t have the race he hoped for but it was still great to see him @renocxnats and “pit” for him. He said he officially started his second off season, but first of 2018. @artroti43 and I played soigneur/mechanic for 90 minutes, but minus the massage! atmo #renocxnats #richardsachs #teamhorstsports @horsteng #crossspikes #hauteframebuilding #Cyclocross #crossisboss #lifedeathcyclocross I previously hadn’t published this image, but it recently received an Honorable Mention in the 2017 @appalachianmountainclub Photo Contest for the People Outdoors category. Check out my blog (link in profile) for the interesting story of his photo (shot with this iPhone 6s), a trip report from this amazing Maine adventure, and past contest history. I love this image of two of my favorite women. I’m barred from submitting images to the 2018 contest, but I’ll be back in 2019. #appalachianmountainclub #baxterstatepark #katahdin Congratulations to Master Park, the Park Family, and the entire team at Park’s U.S. #Taekwondo at the Grand Opening of the new facility in the former VFW building. Our kids love it! So much better than being next door to the pawn shop and liquor store.😊#tkd 🇺🇸🇰🇷 This morning, the @trinitycollege Main Quad was bathed in beautiful sunshine ☀️but it was frigid and the wind was blowing! ❄️ The chapel was packed with an overflow crowd to celebrate the (shortened) life of a lovely friend. She will be missed. #circleoflife 🌏
