First post! New to this site but not new to tandems. Wish I had found this site earlier I would have saved myself a lot of head scratching while determining our final build!
After starting with a Burley then onto a Comotion Java 15 years ago, we finally took delivery of a new Calfee. We put it thru its paces at the recent Eastern Tandem Rally and I can't emphasize enough just how well it rides and handles. It really is a dream bike for us and we literally broke the bank to complete it! But it was worth every penny.
We started with a Dragonfly frame and a new carbon disk fork from Comotion.
DI2 Ultegra, 11-32 11spd
Full hydro brakes, Shimano 160 IceTech rotors
Lightning cranks with Praxis rings, 52/36
Gates CenterTrack belt
Rolf carbon tandem wheels
Chris King headset, tapered fork steerer
Enve seat posts, FSA carbon bars
The hydro disk brakes are simply a revelation, great power and modulation, even thru the Catskill mountains around our home or the terrain of Vermont this weekend. Superb. With many years riding Campy on my singles and on the Comotion, DI2 seemed the best(only) option if we wanted electronic shifting and full hydraulic disks and it did not disappoint. It proved flawless, up/down, under load standing, every time. Impressive. The Rolf wheels we had on our Comotion have performed very well over the last 2 years so we took a chance on the new carbon disc-only Rolf's and so far they have been fine, they are a bit lighter and seem as stiff as the alloy version but they are more of a handful in strong crosswinds. I've read mixed reviews about the Rolf's but so far they have been good to us, so time will tell after we have some more miles on our newest pair. Tires are Conti 4 season 25mm in front and 28mm rear, same as we've used the last few years with good results and ok wear. Would like to try something else and maybe 25mm in the rear also, options?
We are missing only our very smallest gear since we moved to a double crank from our old triple and so far have not missed it even with a lot of very steep climbs, that was one of my worries. As a high performance tandem I think it hits the mark for us, we will play with some small fit adjustments with different bars and stems but otherwise we will just ride!
