Dave Dalton: Owner - Mechanic - Wearer of many hats Name:  Dave Dalton
Position: Owner - Mechanic - Wearer of many hats

Dave started cycling seriously in 1999 when he and his wife did the California Aids ride from San Fran to LA. A ride he describes as “life altering”. They did the ride again in 2001, about the same time a co-worker introduced him to a few guys who to this day are part of the 6Fifteen Crew. From that point he was hooked. Sunday rides turned in to 6 days a week; 50 mile weekend rides turned into 8,500 miles a year; charity rides turned into CAT 3 racing, and tinkering in the garage turned into getting certified as a mechanic. This obsession with cycling led him to start 6Fifteen Cyclery with a vision of building a different kind of bike shop. A shop that is as much fun to hang out in as your best friend’s backyard, one where customer service means everything and one that gives back to the community that it serves. So stop by and say hi, he’ll be the one with the Diet Coke in his hand.

Name:  Sue Dalton
Position: Co-Owner - Operations

Sue started cycling recreationally with friends back in New York with her first "organized" ride being the 5 Boroughs of New York. (Ask her about the Verrazano-Narrows Bridge climb!) This was followed by weekend rides around Long Island experiencing home turf with a new perspective. Fast forward to 1996 when she, husband Dave, and kids Sara and Matt moved to Danville. With perfect weather year-round cycling became a prominent activity in the Dalton household. Charity rides including California Aids Ride, Waves To Wine, Top Hat Classic, Cinderella and more filled the calendar. Sue eventually transitioned into Triathlons to include her number one passion, swimming. Open water swimming at Aquatic Park in San Francisco soon followed. "It wasn't THAT cold" became a typical weekend saying! Nowadays she swims regularly with the San Ramon Valley Masters group and rides when she can!

When Dave decided to make the leap from corporate America and open the bike shop Sue followed along whole-heartedly. This new venture on the road we all call life has brought her a new appreciation for riding - she leads new riders on our Sunday shop rides to help others figure out this cycling thing and enjoys the day to day hustle and bustle of the store.

Dan Hoeppner: Asst. Manager - Head Mechanic Name:  Dan Hoeppner
Position: Asst. Manager - Head Mechanic

Ever since Dan can remember he’s been on a bike. In fact his dad is bike parts engineer and designer so you might say it’s in his DNA. He grew up riding BMX and the competitive spirit that happens naturally among brothers was a continual game of one upsmanship leading to a long list of injuries that make mom’s weep. The worst of which came during a failed backflip (can we agree he’s nuts) at the tender age of 15 that knocked out two front teeth and required 26 stitches. At that point Dan turned to mountain biking, cyclocross and road racing because as he says “they are less painful” (not so sure about that). And, thankfully for us, he also turned to wrenching. He’s been doing it for 9 years and is a graduate of the SBCU Mater Mechanic Course, the Park Tool Tech Summit and the FOX Master Tech Clinic. We are incredibly stoked that Dan, his wife Jamie and children Jaydan and Rosie have moved from Washington to join the 6Fifteen Family. Dan summed up the spirit of our shop, and cycling in general, when he said “I love to work on bikes but I live for the moments when all thoughts, cares, and worries have escaped your mind and you become one with your bike.” 

Name:  Mari Breitenbach
Position: Asst. Manager

Her passion for the outdoors began while attending the University of Colorado at Boulder.  She did her first mountain bike race in Durango and loved the vibe of the racing scene.  She has a 15 year old son, Jaden, who now rides for the Monte Vista High School team.  She was an active member of his team this year as a ride leader and coach.  One day she would like to race again. 

When she is not riding she spends her time dehydrating her own food and backpacking countless miles.  Last summer she enjoyed 165 miles of the PCT.  Her next ventures include a portion of the JMT in Yosemite, Pinnacles National Monument, Henry Coe, Desolation Wilderness and maybe a few nights bikepacking in our own backyard of Mt. Diablo.  She also dabbles in woodworking and builds living walls using reclaimed wood, airplants and succulents for both businesses and residences.

Ruby: Shop Dog Name:  Ruby
Position: Shop Dog

Ruby is our shop dog. Her full AKA name is Paris Roubaix Legends Live Forever (if she was a male she was going to be named Merckx); further evidence of Dave’s obsession with cycling. Anyway she’s not very good with a wrench but she is super friendly and makes for good company. Feel free to rub her belly and give her a treat. At 70lbs and still growing she is always hungry. 





Live to ride or ride to live; it’s your choice…just ride.
