Our New DaVinci Tandem(s)

Just got back from picking up our new bikes. We already have an aluminum Joint Venture (to be advertised for sale soon) and a steel Symbiosis XC hardtail 29" MTB. We decided to upgrade the road bike to a Ti frame with 2 S&S couplers and Di2. With just 2 couplers the bike breaks in half to travel in an EVOC Pro single bike case. We also added a full suspension 27.5" Symbiosis to the fleet. Since the bikes are built in Denver and I've always wanted to ride in Colorado, we flew out from the DC area to pick them up and ride them there before flying home with the road bike. The MTB should arrive via freight in a week or so.

Road bike highlights:
  • Large/Small Titanium Joint Venture with one pair of S&S couplers.
  • Drivetrain - Ultegra Di2 levers with XTR derailleurs. Left side has 34 tooth timing rings with 17 tooth freewheels using 9 speed chains. Right side has 13/21/29 cogs as chainrings yielding an effective 26/42/58. Cassette is an 11-speed 11-40.
  • Brakes are Shimano road hydraulic with 203mm Ice-Tech rotors
  • Wound Up carbon fork partially wrapped in vinyl galaxy image from Hubble telescope
  • Vision Metron 4D front handlebars, Thomson X2 front stem, Profile T2 Wing aluminum rear bars, DaVinci fixed titanium stoker stem
  • Bontrager carbon seatposts front & rear
  • Spinergy FCC 3.2 carbon rims
  • Continental Grand Prix 4 Season Black Edition tires 700 x 28
  • Bottle cages: Supacaz Fly Cage Ano Oil Slick
  • Handlebar tape: Supacaz Galaxy in purple/pink
  • All decals were cut from the same galaxy image as the wrap on the fork
  • DaVinci cranks - 175mm front, 160mm rear
  • Speedplay Frog pedals
Ready to ride weight without pump or tools (includes bottle cages, pedals, computer mounts) 33.6 lbs

I've been following some of the recent discussions about various gearing options and disk vs. rim brakes. If you can climb a 12% grade topping at 9,000 feet less than 3 days after arriving from sea level with less gearing than we have I'm sincerely impressed. We wouldn't have been able to. If you can descend the other side on unfamiliar roads with loose gravel here and there with rim brakes then you must be significantly lighter riders or much braver than I am... we cooked the brakes but while they got loud they never faded.


The new toys. Had to use wide angle mode to get them both in the picture!




We got a lot of compliments on the bottle cages





If you look close you can see the stars in the image on the decals










On top of Lookout Mountain. We climbed it on Tuesday afternoon at the midpoint of a 54 mile solo ride from Denver and again Wednesday morning on a 33 mile group ride from Morrison that came up through Red Rocks and then went on to climb Genesee Mountain.

Congratulations on the new bikes Alan! Can't tell from the pics - is the Symbiosis painted or anodized? They both look great! Hope you have many great adventures on them...

Those are lovely. How are the brake lines handled when you de-couple and transport the road bike?

Thanks Mike. The Symbiosis is painted Sunrise Pearl (House of Kolor PBC30) with a fade to black at the rear to match the black fork. We're very happy with the results.

The rear hydraulic line is kept in the frame guides by small zip ties. Three of the zip ties (the three closest to the rear brake) are cut when we break down the bike and replaced during reassembly. I unmounted both brake calipers from the frame. The rear ended up secured to a seatstay velcro straps to keep it from moving around during transport. The front was removed only because the EVOC bag has fork padding that wouldn't fit over the fork with the brake attached. The front brake was secured next to the fork padding by one of the straps that holds the fork up against the front of the bag.

Didn't even think about pulling the calipers, thought you'd have to drain the lines each time....

Nice!
