986.0. "SEAT POSTS" by WMOIS::C_GIROUARD () Fri Feb 03 1989 09:23

    Can someone respond to seat posts? I've just purchased the Chorus
    gruppo. I did see the C-RECORD seat post (gorgeous), but is beauty
    only skin deep. What are the other top shelf posts, why are some
    better than others and what are the costs and comparisons?
    
    I think that's enough for starters. P.S. the SUNTOUR post on my
    ooollld Fuji was better looking than my Campy.

986.1CSCMA::J_BUSHFri Feb 03 1989 16:0913
    I bought a Chorus seat post to go with my Dura-Ace group because
    the Chorus was 1) cheaper than the Dura-Ace 2) much better looking
    than the Dura-Ace 3) I didn't think a seat post was something I 
    wanted to spend time researching and 4) I had to have something 
    from Campy on my bike. I also thought that, except for the length,
    it was nearly identical to the C-Record. Are you sure it's a Chorus
    seat post that you got with your gruppo?

    Otherwise I'd consider strength and weight (what else, right?) and
    make sure it's long enough. You don't want a seat post at it's maximum
    height splitting your seat tube!

986.2MORE DATAWMOIS::C_GIROUARDFri Feb 03 1989 16:4810
    It'd better be the right one! It looks like an unfinished bar. No
    polish, completely round and has Campagnolo stamed in to the side.
    The C-RECORD one that was shown to me was polished, eliptical
    (aerodynamic) and "real purdee lookin'." 
    
    Mine is ugly. I know that the important things are the things you've
    mentioned, I like it to be pleasing to the eye and functional.
    
    This stuff is my first Campy purchases. Did I get Croce de Aune
    or Athena?
986.3Maybe a New Record?ICBB::JSMITHBikes Spoke_n HereFri Feb 03 1989 16:585
    If its round its probably a New Record.  I just bought a New Record
    on Sale from Colorado Cyclist and at $28.00 think that its a real
    deal but it doesn't have the eliptical shape of the newer Campy
    models.  It's round with flutes and really shines.
    							Jerry
986.4LOOKS LIKE A LOGWMOIS::C_GIROUARDFri Feb 03 1989 17:015
    Sorry, no flutes or shine. This thing looks archaic. I'd better
    ask!
    
    I seriously doubt it's NEW RECORD. I'll bet it was an model that
    was left over.
986.5And Nuovo Record doesn't have flutes either.NOVA::FISHERBMB FinisherFri Feb 03 1989 17:1211
    re: .3.
    
    Round with flutes?  Sounds like Super record?  Has 1 bolt clamping
    the seat rails? 13mm head on the bolt? Actually 12.6mm so that a
    half inch wrnech fits snug and a 13mm fits loose?  that's Super
    Record.  Nuovo Record has two hard to get to clamps that hold the
    seat rails.  that sucker never slips, on the other hand it's so
    hard to make an adjustment, I'd rather ride wrong than fix it
    too often.

986.6CSCMA::J_BUSHFri Feb 03 1989 19:428
    re: .0,.2,.4
    
    That is definitely *not* Chorus! The Chorus is highly polished,
    elliptical below the clamp (round at the bottom of course) and has
    a single bolt adjustment. Go back and tell the people that sold
    it to you that you didn't pay for "leftovers".
    
    Jonathan
986.7HOW 'BOUT THIS?WMOIS::C_GIROUARDMon Feb 06 1989 10:029
    Thanks, I did know immediately that there was a distinct difference
    between the quality. 
    
    I have a CANNONDALE frame that requires a wider post radius than
    a normal "tubed" frame. Could it be that the Campy gruppos don't
    offer that kind of felxibility in post radius'? I haven't spoken
    to them yet, but I don't want to go off half cocked. I'm sure I
    paid for what I got. It's just so damned ugly compared to the
    rest of the highly polished/anodized components!
986.8Criteria?USWAV7::CLELANDToo cold for pedaling you say?Mon Feb 06 1989 12:5927
    Re .0
    
    	Perhaps others have different criteria for their selection,
    	but for me, I've always preferred Campagnolo, Super Record.
    
    	To me, criteria for a preferential seatpost would include:
    
    	#1) Weight.  My most critical factor.
    
    	#2) Durability. How many years before it'll bend/break/corrode?
    
    	#3) Appearance. Satiny smooth is preferred to blatant chrome.
    
    	#4) Price.  Anything over $39.99 is out of the question.
    
        My all-time FAVORITE seatpost was manufactured by WEYLESS.
    	I purchased a set of hubs & a seat-post from this company,
    	and they still are the lightest components I've ever owned.
    
    	Since Weyless went out of business sometime around 1980 (?)
    	I've only found one component line that I really like, and
    	it's always been Super Record. At under $40, this seatpost is
    	a far better investment than the C-record. Now I'll just duck
    	behind this steel plate to dodge the incredible counter -
    	points and ridicule that I know will follow...
    
    							Face.
986.9ON THE CONTRARY!WMOIS::C_GIROUARDMon Feb 06 1989 15:019
    Hey, all inputs welcome. I agree with all of the points. They're
    my pursuits as well. Help me out, though. I've seen the C-RECORD
    seat post. What is the difference between C-RECORD AND SUPER RECORD?
    
    And don't tell me about $5.95! (ho, ho, ho)
    
    Thanks,
    
    Chip
986.10The sky is blue but it's cold and wet out there.NOVA::FISHERBMB FinisherMon Feb 06 1989 17:5412
    The C-Record seatpost has an aero (aka, oval) upper section and
    the bolt which holds the clamp for the seat rails has a hole for
    a 6mm allen key. There is a campy logo on the polished oval section,
    maybe even one on each side.
    
    The super record is polished, fluted, has a script Campagnolo on
    the front.  The bolt which holds the clamp for the seat rails is
    a 13mm hex head though a 1/2" fits better.
    
    No, I do not have a pair of seat posts in front of me.

    	The Third Hand catalog notes that in wind tunnel tests, these
    oval seatposts did indeed prove to be "aero" - at 60mph and up.
986.12the seatpost - that extra edge!ATLAST::ELLISJohn Lee Ellis - assembly requiredTue Feb 07 1989 09:236
    RE: .-2  The C-Record seatpost in front of me does look like that.
    
    RE: .-1  The aerodynamic threshold (60mph?) could well prove useful
             in staying out from under agressive 18-wheelers?

986.1360 MPH - GOTTA HAVE IT!WMOIS::C_GIROUARDTue Feb 07 1989 09:3211
    Gee, I guess I'd better go for the aero design that performs a 60mph.
    After all, that's what I normally operate at (when I'm coming down
    Mt. Washington) on a recreational ride.
    
    Seriously, thanks to all. However, I asked a question a little way
    back. Could the fact that I have a CANNONDALE frame be the reason
    I ended up with a "club" instead of the beautiful CHORUS post?
    
    I thought the dealer said it required a larger diameter post.

986.14Nuevo Super Record = Super Record?ICBB::JSMITHBikes Spoke_n HereTue Feb 07 1989 11:1914
    Chip,
    	The seat post I called a NEW RECORD that has been acurately
    described here as a SUPER RECORD (It Says Nuevo Super Record on
    the fine crafted *Italian* box...translated *loosley*) fits my
    C-Dale which has a 27.2 seat post.  All of the Campy post I have
    seen advertised come in either 25.0 or 27.2 and the larger version
    seems to fit well.  As for the previous note on preference of
    Super Record over C-Record I'll second that motion.  (Until I can afford
    the complete C-Record Group that is....who would break up a
    combination like that???).  Since the C-Dale diameter issue has
    been ruled out you better get your post back to the dealer before
    he forgets your name.
    						Jerry
    
986.15THANKS - A LOT!WMOIS::C_GIROUARDTue Feb 07 1989 13:196

986.16NO THANKS, I OWN A BRIDGE!WMOIS::C_GIROUARDTue Feb 07 1989 15:2316
    Here's the update: Called 'em this morning. Here's what I got:
    What I got is a Nuevo Record post. I was told that they couldn't
    get the CHORUS post because of the measurement that I required.
    I stated that I was operating from an understanding that they
    came in a variety of lengths and that I couldn't understand why
    it was a problem. He said you're right, I'll get the order in.
    Help me, my head is spinning.
    
    So... I'm 5'6 1/2 (I know it's short) but my legs a long for my
    my total height (short body). I know it's short, but it's a
    fairly common height (I think) and I don't consider that they
    should consider it unique. Am I wrong? 
    
    Short, but not microscoipic!
    
    Chip    :-)
986.17Where have all the sizes gone?SUSHI::KMACDONALDdrywall 'til ya drop!Tue Feb 07 1989 19:0110
re: back a couple - seat post sizes from the big C...

In the ancient daze, don't know about now with Chorus and Anathema and 
all the 'new' Campag stuff, but years ago the Campag (Record? Super 
Record?) posts came in lots of diameters and lengths. Something on the 
order of from 25.0 - 28.0 in increments of .2 mm. I've had bikes which 
required 26.4, 26.8, 27.0, and 27.2 and Campag had 'em all, including 
some ex-tra long ones. It'd be too bad if their recent lines only come
in 25.0 and 27.2!

986.18aero post USMRM5::MREIDWed Feb 08 1989 13:5012
    I heard that Campy's reason for aero seatposts is that the aero
    design allows more air to flow between your thighs - thereby cooling
    the muscles in the area a little bit more - thereby offering a slight
    advantage in performance. 
    
    OOOOoooo, I know that 2 mm more air between my thighs turns me into
    a time trial madman! 
    
    Sounds like a wimpy reason to me!

986.19that was supposed to be a secret!BANZAI::FISHERBMB FinisherWed Feb 08 1989 14:298
    I tried to keep that a secret!  Using a round seatpost in the 
    winter to keep warm and an oval one in the summer to keep cool
    is one of those small things you just don't tell everyone.
    
    If you do they look at you like you got two heads, just like they
    do after you tell them you been ridin' all week.

986.20arteries for that extra edge!!ATLAST::ELLISJohn Lee Ellis - assembly requiredWed Feb 08 1989 22:158
   RE: .-2 -- the story I heard was similar - not so much muscle cooling,
   but rather the major arterial artery [please supply latin name] runs
   on the inside of the thigh - and any extra cooling/air-flow for that
   artery would be much appreciated by the whole leg.

   RE: .-1 -- rats, there goes my competitive advantage!

	re: -1 and others

	Next time you're out riding, look down and see where your
	seat post is in relation to your thighs.  It's pretty hard
	to imagine the shape of the post making any difference in
	the amount of air cooling you legs!

986.22A SHATTERED ILLUSIONWMOIS::C_GIROUARDThu Feb 09 1989 09:224

986.23What's another rathole between friends?TALOS4::JDJD DoyleThu Feb 09 1989 12:5110
    
    I suppose on cool days you turn it sideways, and it keep your legs
    warmer?  It's really 2 seatposts in 1!  That's why it cost twice
    as much as it should.
    
    Oh wait, now I need a aeordynamic tire sock.

986.24ad nauseumCSCMA::J_BUSHThu Feb 09 1989 14:5412
    
    It must be February for a discussion about a steel tube to generate
    this much attention! Besides, aero posts were really made for people
    who's thighs were so big that they rubbed against round ones. :^)
    
    If you are still having trouble getting a seat post check out one
    manufactured by American. It is very light, polished and comes in
    a variety of sizes. When I first saw one it reminded me of a Weyless
    post (mentioned earlier). But, it is round so you may notice extra 
    turbulence at speeds > 60 mph.

986.25TO AERO OR NOT TO AERO...THAT IS THE QUESTIONAKOV11::FULLERThu Feb 09 1989 15:406
    For those considering this serious purchase.  If your ride on a frame
    slightly larger than optimum, you may have problems with an aero
    post, as the seat binder will be bolting down on the aero portion
    causing too much stress on the seat binder.

986.26THE ANSWERWMOIS::C_GIROUARDMon Feb 13 1989 15:258
    Hi, it's me again. I went through a great deal of research with
    my problem. The answer; .25 is close to mine. The frame on the
    CANNONDALE would not allow a secure fit due to the length of the
    aero piece on the post. If the aero section were shorter I'd have
    no problem. I am going to look around for something a little 
    different, Unless I polish the thing myself.

986.27CONSLT::MCBRIDEIdleness, the holiday of foolsTue Jun 18 1996 18:0111
    I am looking to replace the seatpost on my mountain bike.  The
    original one from GT had a known failure and would not keep decent 
    tension on the seat, allowing it to tilt back and forth.  It was replaced 
    with an el cheapo one under a warranty program.  Is there a big difference
    in posts for mountain bikes other than weight?  I've been looking at
    Moby Posts due to the adjustment lines in etched in but other than that,
    I have not been able to justify $79.99 for a post.  Any recommendations  
    on a decent post?
