Final Build - Pricing & Weights
Still working on putting together a full report, and I keep getting distracted with other things, so I thought I would share a couple of things now.
The first is a price comparison of an English Travel Tandem Frame vs. a Calfee Tetra Tandem Frame w/ Couplers:
The English is a significant amount less money than the Calfee. It would be great if I had the finances to purchase one of each and do a thorough comparison, but alas that is not to be. So here's what I know about the differences:
- The English is very smooth and comfortable
- All reports are that Calfee makes some of the most comfortable tandems
- The English: 8.23 lbs (3,732 g) with a 57.3 cm captain HTT and a 31" stoker compartment.
- TG's Calfee Tetra w/ Ti couplers: 8.75 lbs (3,968 g) with a 53 cm captain HTT and a 30" stoker compartment.
- I think I read someplace that you can now get aluminum couplers. That would drop the Calfee's weight significantly. Can someone confirm what material Calfee uses for the couplers now?
- The English has a basic powder coat with decals on top. It looks pretty good. Wet paint is extra.
- The Calfee tandems I have seen in person and have seen pictures of have some pretty awesome paint.
- Most tandem teams we meet will have never heard of English Cycles.
- The Calfee name is well known and and respected for good reason.
- The English: Steel w/ Ti midtubes
- Calfee: Carbon w/ Ti couplers and SS dropouts
What else is different? Help me out here.
I also did a spreadsheet showing our final build with prices and weights.
I'm very pleased with the final weight of 28.45 lbs w/out pedals and bottle cages. This will drop to approx. ~28.12 as soon as I get some new tires. (I had previously converted the Rolfs to tubeless and it gave a much improved ride on the C'dale, but tubeless just doesn't work on a travel tandem.)
As expected when doing a custom build spec, I do see a couple of components I might want to change out in the future. The seatpost collars were chosen with an eye towards durability on a travel tandem. There are several lighter weight options (e.g. KCNC SC9 at 26g for two). The 54T chainring is rather portly at 204 grams, and I'm not quite sure I like the look of it. A friend has loaned me a used DA-7800 53T to experiment with. Time will tell.
I'm still very pleased with the result. :)
More to come in the future.
