My stoker recently died, so I won't be riding our tandems anymore. Lynn Dexter from Tandem Bicycle Tours told me that many Colorado tandem cyclists spend time in Tucson, and she suggested that I post the tandems on your club website If you will be in Tucson this winter and need a tandem, I have two tandems to sell. One is our really good S&S Coupled Co-Motion tandem along with travel cases and some accessories. We only used it for trips so it has low mileage. The other is our older Cannondale that we used for all our daily rides in Tucson. They are both posted on Facebook Marketplace with photos and details about size and other issues.

Regretfully, we're having to sell our Calfee Tetra (Carbon frame) Tandem with S&S Couplers (includes 2 hard travel cases with padding, and LongBikeTote Tandem car rack). Asking price is $8450. Recently, it was sent to Calfee for a new factory re-paint, and servicing of couplers ($2400 value). It is in excellent shape and perfect working condition. The light-weight, stiff carbon frame makes it ideal for climbing hills and cruising at high speeds. Specifications are listed below.

We're the Vollers, just joined the club. Looking forward to meeting folks. We're new to tandems, long-time road bicyclists. Riding tandem is our latest little adventure. Purchased a new-old-stock Cannondale RT2 from Any and All Bikes in Englewood last month. Gorgeous bike. Very excited! Working on just the basics - starting, stopping, maneuvering, coordinating, all that... :) Focused practice in our neighborhood at this point, no longer rides just yet. I've (Brian) determined that I have some bad habits from road riding that I'm working on, lol. All good. Lots of questions. Looking forward to connecting with you all.

Age makes it necessary to sell our beloved Erickson tandem travel bike. This was hand-built in 2006 by legendary frame and tandem builder Glenn Erickson in Seattle. It was one of the last tandems that Glenn made (he died in 2024 after a long illness). It is his “Signature” model, which features gorgeous fillet brazed, hand ground steel joints, and premium paint. It has stainless steel S&S couplers for travel and fits into two airline-legal hard cases. Full specs are listed below.

This bike has taken us on many adventures in the US, Canada, New Zealand, and Europe.  Despite its age, it’s ready to take you on many more! Major upgrades over the years include a Wound Up carbon fork, TRP Spyre disk brakes, Rock Shox rear seat post, complete drive train replacement and new wheels in 2020. As with any well-used travel bike it has several cosmetic scrapes and…
