    Calfee Tetra Tandem

    We are going to the Calfee factory tomorrow to look at the tetra tandem. We do the occasional race, some touring (with a trailer), centuries, training and fun rides. We are 300-310 team weight. Here is how I envision the core set up:

    Dura-ace 10
    Santana carbon fiber cranks
    topolino wheels
    203 mm disc on rear (as well as the caliper brakes), set with friction shifter on the captains bar end for additional braking when necessary.

    Questions are:

    Is a seat post rack adequate for carrying the standard stuff like: clothing, food, etc. maybe 15lbs of gear?
    Or should I put a real rack on when necessary.

    is the rear disc brake lever at the stokers control a good idea? I hesitate to do this b/c of a panic braking situation which may cause a rear tire skid in a turn.

    Do you have any other recommendations on setup?

    Thanks for your input.

    I won't comment on the wheels or cranks because I know nothing about them - I wouldn't do loaded touring on low spoke count wheels but that's just me. I also don't like proprietary stuff, especially when it comes to cranks etc - unless the replaceable stuff like chainrings and bottom bracket bearings are common and easily found. You guys don't weigh anything so I'd opt for the Dragon Fly version to save weight.

    As for running a disc as a drag brake controlled by the stoker (or anyone for that matter) is a bad idea IMO. If you want a drag brake - buy a drum. If not - run the disc by itself. Doesn't sound like your going to be doing any loaded touring - so there really isn't any need for both a caliper and disc. I set up my tandem for a v-brake/drum combo for loaded touring and I normally run just a rear disc.

    I've never used seatpost racks - because I never saw any advantage to them - and I also run carbon fiber seat posts and you really shouldn't bolt anything to a pure carbon fiber seatpost that is going to hold any weight at all. Woundup CF posts are different because they are carbon wrapped aluminum. I really like the new Bontrager disc compatible rear rack which can be used with the new Trek bags that snap on and off.

    Thanks for the input.

    As you can tell I am trying to make this the best of all worlds setup, which is difficult. The Topolino wheels are very strong, according to Craig. http://www.topolinotech.com/

    We are probably going to run a thudbuster seat post for the stoker, which is aluminum-so running a bolt on rack should not be a problem. Just have to size the frame properly so that there is enough seatpost / tire clearance. A bolt on rack would give us more options.

    We are planning on doing some touring pulling a trailer. I know this will require additional braking power on the decents. Having the disc brake operated by a friction shifter on the bar end would give me the ability to use the calipers and disc. I will have to be careful not to overheat the disc with this set up.

    I have the fsa carbon cranks on my current tandem, but they are getting pretty back ordered. Craig recommended the Santana carbon cranks. They use the shimano pipe splined bottom bracket and shimano chainrings.

    Calfee Tandem

    Seat post bag will depend on how much space between tire and bottom of bag. I know I am saying the obvious, but for my stoker, the distance between the bottom of her seat and the top of the tire precluded us from being able to use a bag. Ended up using a Tubus rack and have been very pleased.

    Using an Avid 203 rear disc and have been very pleased. We live in a very hilly part of Indiana but wanted the disc even more for trips to Hawaii and Europe where we want to be going up and down the mountains.

    If you use the topolino wheel, you will have to use rear calipers as you can use a disc with that wheel. We ended up with the Rolfs and have been very happy with them.

    Enjoy this wonderful journey called building up your Calfee. I was not able to cure my carbon lust so just decided to succomb.

    Tandemgeek: I was on the phone with Craig and mentioned that this forum has been a great source of information for Michelle and I. I knew that you had a tandem, under construction, at Calfee and mentioned to Craig that you have been very helpful with tandem/cycling information. He will actually be going to Tucson tomorrow so we will miss meeting him this time.

    Benefits of the rack as I see it are:
    - shorter overall bike package (as compared to a trailer), easier to park the bike, etc.
    - easier to store when not using
    - works well for short trips as well as long

    Benefits of trailer:
    - carry more stuff
    - more aerodynamic?

    Wheels:

    Definitely going with a rear disc. Perhaps we can get away without having the rear caliper brake.

    I thought the topolino wheels could go disc...Maybe they can now. The subject of not being able to use the topolino wheels with disc did not come up when speaking with Craig.

    Thanks for the input. Excited for our factory tour tomorrow.

    Topolinos are *nice*! But, as stated, cannot use disc/drum with them.
    Have Topos on my single and have run the front Topo on the tandem. No issues.
    Seatpost rack would be fine, depending on the seatpost. Most racks are designed to take up to 25 lbs.
    Having said that, we have a full c/f custom rack on our c/f Zona tandem.
    On a Calfee, your stoker may not need a suspension seatpost.
    Would not recommend using a disc as a drag brake . . .
    If you use seatpost mounted rack, you'll have to remove it in order to clamp trailer hitch to seatpost . . .
    would not clamp any part of trailer hitch/support onto the c/f frame.
    Agree with Mark in as we get 'a bit older', we tend to sit more upright.
    Designed our last 2 tandems with 1" higher headtube to accomodate our aging bods + also sloped top tube down more aggressively for both pilot and ultra-short stoker.
    Carbon is a whole other ride when it comes to tandems . . . love it!

    I'm sure they are strong - as are the Rolfs on my tandem, but I still wouldn't do loaded touring with them. Which means racks and panniers front and rear.

    How can a rack that is limited in terms of its weight carrying capacity and in most cases in ability to be used with real panniers give you more options?

    How big a trailer? How much weight? What do you mean by "being careful to not overheat the disc"? Discs shouldn't be used for drag brakes. They are not designed for it. I'd rather have the peace of mind that my brakes will work like they should in all situations.

    I haven't seen em and Santana doesn't have any pics on their website either by themselves or on a tandem that I can find. Since they use common rings and BB that's a definite plus.

    "Santana's" carbon cranks are a special order item that they buy through FSA and that have in past carried the FSA Carbon Pro branding. I suspect they still carry the FSA branding for the cachet. I snagged this off of Wolfgang's Santana-Europe website but there's also a small picture on Santana's US site that appears in the left-hand margin of the Team Component page.


    New FSA carbon fiber crankset combines the beauty and weight savings of carbon with the efficiency of Octalink splines. Chainrings 53/42/30 or 55/44/32 (48/38/24)

    I'd be interested in seeing the actual weight of these cranks. While I like carbon for certain components, they aren't always as light as consumers might be led to believe vs. the alloy alternatives, e.g., Thomson Masterpiece seatposts, X2 stems, Deda 215 handlebars, and daVinci crank weights might surprise some folks who have assumed carbon alternatives were lighter.

    It's certainly true that Santana has been using FSA Carbon Pro cranks (we have some on our Santana Team Niobium purchased in January 2006) and they may still be using those. However, I had a casual conversation with Jack from Tandems Ltd at the Southern Tandem Rally and I asked about what Santana was doing about carbon cranks since I understood that FSA was not making octalink anymore. He said that Winwood was going to be making cranks for Santana. When I started seeing references on this forum to the Santana crank I just figured that Winwood was already making the crank for Santana. Santana never referred to the FSA crank as the Santana crank as far as I know.

    Perhaps it's like in the old days of "Schwinn Approved" components, now we may have "Santana Approved" components?
    Agree with Mark that c/f components are not always 'the' lightest. But learned through the years that 'the' lightest did not always hold up under 2 folks torqueing on a tandem.
    Recall twisting off a super-light front derailleur on a 100-miler . . . lesson learned!

    Here are some responses to your responses

    Good point. Will have to look into that. Maybe have a set of gofast wheels and a set of touring.

    How can a rack that is limited in terms of its weight carrying capacity and in most cases in ability to be used with real panniers give you more options?

    I was unclear with my explanation. A rack that fastens to the frame would give more options than a rack that only attaches to the seat post.


    How big a trailer? How much weight? What do you mean by "being careful to not overheat the disc"? Discs shouldn't be used for drag brakes. They are not designed for it. I'd rather have the peace of mind that my brakes will work like they should in all situations.

    Hmmmm. If that's the case and FSA is not still in the supply chain the 'other name' I've heard used for Santana's cranks is Aprebic. Now that's not to say that they aren't carrying the Winwood brand: Winwood is one of Quality Bicycle Product's house-brands, along with Civa, Dimension, Problem Solvers, Salsa, and Surley. Aprebic is just one of many suppliers to many different brands.

    I seem to recall that mburchard has them on his Calfee: http://www.bikeforums.net/attachment...9&d=1189896501

    In doing a quick surf, the crank arms & spider design on mburchard's tandems 'look' like dead ringers for the 110 BCD ones made by BEV:http://www.bev-intl.com/crank/crc322.jpg

    But, again, in other conversations I've hard relative to cranks and our Calfee the name 'Aprebic' is what has come up and, again, I want to say that Aprebic would make sense as I believe they make the Evo carbon fork used by Santana.

    No, whatever they are -- FSA, Aprebic, BEV, Winwood, or none of the above -- they're spec'd with Shimano's Octalink BB.

    With regards to the Santana cranks - those are the lower line FSA CF cranks compared to thier one piece molded sets. I'd skip em as they aren't near as strong as the Mega Exo's or the previous high end FSA's like the Carbon Pro Team issues.



    Don't know about the other companies mentioned that might make them for Santana. Octalinks aren't the best BB out their either as i've never gotten much wear out of them.

    Our friends just bough a daVinci and their cranks are beautiful - but I hate to admit I just don't want square taper cranks anymore.

    Santana has license to use octilink I beleive. They have special BB's made up.

    They are indeed... while being extremely light and stiff enough for lighweight and most average teams. As for square tapers, again... thankfully as a lightweight non-pro cyclist I have neither the weight nor power to require anything stronger or stiffer than various different square taper cranks and BBs in our stable.

    The only down side to these cranks is that their polished aluminum finish is easily mared by the acids in perspiration. Once they're stained it takes some effort to buff them up. Taking about 30 seconds to wash them off with a squirt from your water bottle and a wipe of your hand after a hot sweaty ride will go a long way towards keeping their luster.

    I use Mother's aluminum wheel polish on ours, followed by a coating of a polymer-based auto wax. Even the oldest ones still shine, although the ones on our off-road tandem look pretty rough. However, the worst I've seen belong to some friends where their one-key / self-extractors are even fused in place. I refinished them once -- about 1hr on a buffing wheel: never again.

    I have to admit - i've gotten lazy. I had square tapers on my roadbikes for years - all Campy Record stuff. Using a crank puller was just a PITA. Now with the "pipe" bb and even the Isis with one-key/self-extractors - it's just so much simpler to deal with.

    Mothers Billet works great. Not sure what polymer based wax you use but like KLASSE works great on polished aluminum. They have a polymer cleaner polish (red bottle) and sealant glaze (silver bottle). It's not a "wax" per se.

    Where do you think the use of one-key / self-extractors began? Square tapers.... Seriously though, I've been using self extractors since the 90's on our tandems: slick as baby-you-know-what.

    Not trying to sell anyone on the tapers, but unless you're a monster-masher team that was tearing up square taper BB's, they continue to be a great choice. In fact, FSA recently brought both square taper cranks and the JIS Ultimax square taper BB's back into its crank line. While I don't think titanium BB spindles are a good choice for the stoker's cranks on a tandem, they do fine up front for the average captain and those suckers are pretty light. No, square tapers are not cutting edge but I'd hate to see anyone discount daVinci, Specialites TA, or Middleburn cranks 'because' of any false perceptions about square taper BBs. This is particularly true for any team that may need very long or very short crank lengths up front or for the stoker, options that aren't available with most of the popular carbon cranks.

    Octalink BBs are actually pretty reliable when compared to most of the early ISIS stuff and would be my second choice at this point vs. ISIS. Some of the late-to-the-party ISIS BBs are getting better (Crank Bro's cobalts seem pretty sweet). Moreover, if ISIS had worked-well, Mega-Exo, Giga-Pipe, and the other outboard bearing models would have never been developed. Somehow, I suspect we haven't seen the last "better mousetrap" with these outboard bearing designs as they seem to require more skill and attention to detail to install than many so-called mechanics and home-wrenchers posses. Yeah, the alloy bolts used early on were dumber-than-dirt, but it seems as if the new steel bolts are used with Loctite and the proper torque values, per the installation specs, the better quality outboard bearing BBs aren't as bad as some reviews and chatter on the web may suggest. Will they or the best ISIS and Octalink's outlast a better quality square taper? Hard to know.

    I'll take a close look tonight and see if there is anything that gives it away. Did see them in the box at the LBS, but it was completely plain cardboard.

    On the Octalink BBs, benefit of the triple spindle (over double) for Dura Ace is that bearings are cartridge (easy to find in Italian, harder in English).

    joe@vwvortex, Topolinos are certainly not high spoke count, but not sure they are low spoke count either, at 24 for the front and 30 for the back. But as people have correctly pointed out, they do not make a rear wheel that will take a disc.

    Oh - i'm aware of that - although having to work against the press fit of the taper made them more problematic so I stopped using them when I moved to Campy stuff. Not to mention the consistent wear on the inner part of the crank arm taper where it mates to the BB. The splines make removal easier and pretty much eliminate damage to the crank itself.

Moreover, if ISIS had worked-well, Mega-Exo, Giga-Pipe, and the other outboard bearing models would have never been developed.
    I disagree - since Shimano was first to market with their outboard BB system - so I wouldn't pin it on the ISIS BB's. It's as much marketing as it is "advancement" in technology. However, the problems with ISIS using smaller bearings due to increased BB spindle diameter have been pretty much rectified with quad bearing systems. Haven't had to touch my FSA quads on the tandem in three years. I used to replace my Octalinks yearly on my MTB's. I've got the new outboard stuff on my MTB's and Tandem and while i'm not convinced it's the greatest - they seem to have held up well and make servicing them a breeze.

Will they or the best ISIS and Octalink's outlast a better quality square taper? Hard to know.
    I don't think any of the different designs will last any longer than the others if properly maintained. With the exception of Phil Wood BB's (and possible some others) which use two internal lock rings - you still have to properly face a BB shell with any square taper (such as campy) or any Octalink or Isis or outboard bearing system. It is FAR simpler IMO to install or remove outboard bearings as the wrench grasps the entire bearing on the outside rather than fitting a special tool inside the lockring to install or remove a BB.

    Ok - i'm familiar with Zaino - some people swear by it on the car forums.

    Anything less than 32 spoke 3x is low spoke count IMO. I bit more old fashion in that respect. I wonder why they don't offer a rear disc. Again - I don't know much about them - checked out their site - but that's about it - never seen em in person.

    I'll concede the point as I'm out of my depth here. For the most part I'm going on second-hand information from others who have owned bikes -- primarily off-road tandems -- with the non-square taper BBs and experienced less than expected lifespans.

    On a tangient to the way this thread is unfolding, has any one seen or heard of any Tandem Cranksets that will use the outboard bearing like my Shimano 7800's. Seems like it should be just about time?

    Again, everything I have in the livery is running on square taper BBs. While I was tempted to take a bite of the forbidden fruit on our Calfee build, the bicycle Gods interceded and doused my carbon lust by keeping what I needed just out of reach, e.g., 170/170 SL-K. Again, in retrospect and after the cold shower, the daVinci cranks with Phil Wood SS & Ti BB's is a better 'fit' for our needs and, well, I already had an extra set of 170mm front cranks.
    Again - I don't think there is anything wrong with em - hell I was running a Phil BB with swiss threaded cups/inserts on my old Motobecane back in 1981 Phil makes great stuff. Still use his grease exclusively. However - that's back then I only had one bike to work on and now with both my and the wife's stable and the tandem - I like stuff that is quick and easy.

    FSA has SLK Carbon Mega EXO's for tandems. They were actually spec'd for our CoMo when we ordered it in Nov 2004. However, they were delayed and we wound up with the Carbon Pro's instead. The Mega EXO's are a bit heavier overall than the pro's and they use the different type of CF mold/weave, but are pretty nice. I run FSA K-Force Compacts on both my wife and I's roadbikes and they've been trouble free.
