    Another new Calfee build

    I put in an order today for a new Calfee build below. There are still a couple open items for components where I'm hoping to get some feedback:

    Calfee Tetra M/S frame
    Nude carbon
    TRP thru-axle cross disk fork (397 A-C, 47mm rake) (Total HT length = 13.5cm)
    Chris king headset
    Bushnell Eccentric
    15mm front thru axle/100mm
    142x12 rear thru axle
    Shimamo Ultegra DI2 11 speed internal cable routing with seat post battery
    11-32 11 speed Ultegra cassette
    Lightning crankset 172.5 captain cranks, 170mm stoker cranks, Praxis chainrings 50/34
    Gates centertrack belt drive
    Enve seat posts
    Enve captain and stoker stems
    Profile Viper Wing 46cm stoker bars
    Specialized Evo Pro 155mm captain saddle
    Terry Women's FLX Carbon Saddle all-black
    Shimano RS785 hydraulic brakes
    Jaqwire hy/flow custom hydraulic lines front and rear
    Shimano XTR icetech rotors 180/203
    28mm continental 4000s II tires
    Enve bottle cages
    Enve Garmin mount

    DT Swiss CLD hubs
    DT aerolite or aerocomp spokes
    Zipp 404 rims 28 hole - if available


    The open items are the hubs, spokes, and rims. Apparently Wheelbuilder is having difficulty getting Zipp 404 rims with 28 spoke count. So, there's a possibility those rims may not be an option. Then, Calfee was suggesting the DT Swiss CLD hubs over the WI CLD hubs. I've noticed a couple tandems recently built up with the WI CLD hubs. What do people see as the tradeoffs between these hubs? Calfee originally suggested aerolite spokes, but I believe people were recommending the aerocomp spokes for their added strength. Thoughts?

    Thanks for all the help. This forum has been really helpful in figuring out build details.

    Well ok, it's sort of a nice build if you like that kind of thing.

    I posted in another thread an answer to the hub question... WI uses CroMo axles instead of AL, and WI rear hub has more bearings (tandem = heavy duty usage), yet the CLD hub weights are still fairly close and the WI hubs are a bit less expensive. DT's only advantage I can see is the ease of switching out the hub ends (QR/TA) FWIW, but WI does also have kits to change out (though it's a more involved process).

    Wide road bars can be a problem for some people. It manifests as sore neck or pain between the shoulder blades. Take note of that with your 46cm stoker bars. My petite stoker uses 38cm bars on her road bike, but even though our 42cm stoker bars sometimes cause my stoker's thumbs to touch the rear of my thighs, it is the best ergo setup for her that we can achieve on a tandem. No issues.

    Spokes: 28h tandem disc wheels, go with the beefier spokes... aero comp (these are flattened comps). Contrary to the specs, visually they are very similar to the lights.

    Brad, will you be at NWTR in Bellingham? If so, I am planning a Mt Baker assault ride on July 2nd from Glacier. I've announced it to ETC (Evergreen Tandem Club) and a few other people. Think about it.

    thanks for the input. I will switch to the WI hubs and aerocomp spokes. Also thanks for thr input on the stoker bars. We are currently using the 46cm bars on our santana tandem to clear my butt, but i wonder if we can get away with more narrow bars on the calfee. My stoker uses 38cm bars on her road bike.

    We are planning to go to NWTR, and calfee is trying to get the bike ready before then. We are currently scheduled to arrive on july 3, but the mt baker ride sounds fun. We will see about possibility of coming earlier. Several of our tandem friends from bay area will also be there.

    I like your specs, it has a strange resemblance to our recent build The White Industry hubs have super smooth bearings. I really like the way our wheels came out with the Aero comp spokes. You will like the new ride!!!

    Yes, I liked your specs so much, that I knew I didn't need to change much. Thanks for your help and the help of others in figuring out the right mix of components for a great Calfee build! My wife and I are really excited about the new ride! We think it will be a nice upgrade from our 2001 Santana Team Aluminum tandem bike! And, now we will have a tandem rain bike (very helpful in Portland) and tandem summer bike.

    My stoker has 38cm bars on her single, I think we have 42cm on the tandem and it is just wide enough.
    It might be different with the cow horn bars you want to use. We have FSA wing pro and really like them.
    You might want to double check the length on the stoker cranks, we used to have 170mm but my wife likes 165mm better, she is 5'2".
    We recently changed her saddle from a Terry Butterfly because she was having some discomfort and now is using a Selle Italia Diva which she likes better.
    We have used Continental GP4000S tires for a long time and they are great tires, but recently I decided to try a Michelin Pro4 Endurance 25mm.
    I started with it on the front and noticed it felt much smoother but didn't like the loss of road feel I had with the GP4000S 23mm, so I moved the Michelin to back and my wife noticed the ride was less bumpy so its staying there.

    we're also in the process of specing a Calfee. We're going with 28 spoke Enve Classic 65 rims.

    Calfee is suggesting aerolite spokes, but at a team weight of 340, I'm thinking aero comp.

    The aerocomps seem to be everybody's preference. I'm wondering if that is in part because the load put on a wheel by disc brakes. (we're going with rim brakes.)
    You could fall off a cliff and die.
    You could get lost and die.
    You could hit a tree and die.
    OR YOU COULD STAY HOME AND FALL OFF THE COUCH AND DIE.

    calfee also suggested aerolote spokes to us (even with disc brakes). But as you said, everyone here seems to suggest aerocomps, sp i went with those spokes.

    Interesting that ENVE seems to have removed "Rims" from their website and only advertising full wheelsets. What's up with that?!

    One thing about Enve Classic 65 rims, AFAIK, they have a fairly narrow inside measurement, so you will not be benefiting from a general industry move to wider rims. Most carbon clinchers must have a minimum of 25mm outer to leave 18mm or so on the inner and sufficient air volume to provide a nicer ride quality. The Classic 65 is something like 22mm outer, and maybe 15mm inner.

    As for the DT Aero Comp choice, well, when you are heading for a 28 spoke count and tandem load forces combined with disc brakes, trying to use 28 Aerolights (flattened Revos) are maybe dancing with the devil. Ritterview has a 28 spoke DT Comp (same spoke as Aero Comp) on his ENVE 65 wheels.

    Agree aero comps should be the go to spoke on the Enve 65's, having real life experience with the 65's with Dura Ace rim brakes I have not encountered any problems with the over all strength on this wheelset. As far as tire selection using conti's s2 23/25 there is no problems with either in handing at speeds, ones a little more aero, the other a little bit softer ride. One of our favorite rides is a 12 mile climb with 5 k vertical, on the descent I can't honestly tell the difference in handling, as a ex Europa Cup racer I used to ridicule some of my compatriots who'd be whining that they'd need a 1/2 degree more bevel in the S.G. Because they where slow! It's all about your line & how comfortable you are at speeds & how big of a scream your stroker has!image.jpg
