New Trek Postal Frame(13 posts)

New Trek Postal FrameTSuprano

There are a few things I would like to point out about the new postal frame. I first off wonder about the engineering of it. I am not a big Trek fan, and having rode the 5500 frame for about 1200 miles, I thought there was way to much flex in the frame. This new frame is interesting, but not in a positive way though. First, they say it is semi sloping, but yet I don't see any slope in it from Lance's page. Does anyone have a better picture? Second of all, the seat tube, what is it with the shape. Ususally they take on the shape to make room for the wheel, but there is a good inch and half or so from the tube to the tire. What advantage would that shape provide. My honest opinion, 5900 and 5500 sales are down. Giant TCR composite as well as other carbon entries are threatening Trek, so they produced the gimmick.

My LBS actually is selling the heck out of the OCLV, but not moving nearly as many Giants as he thought he would. He's even selling more 2300's, which are aluminum vs. the carbon Giants. I don't know why, I personally would probably try the Giant, it definately is one sharp looking machine.

From my understanding of the Giant Composite for the model year 2003, there were 2000 frames produced for world distrubution. They were allocated only a few per dealer, with a 2nd re-order of small quantities to select dealers. This re-order took place last month.

I do not think it is even available anymore - sold out.

Hence dealers who have one for display but are not pushing them. They can't get more. Unless I was told pure BS which is also possible.
the reason giant lacks...bugleboy

anytime you only produce 4 frame sizes makes you wonder about the company's commitment to cyclist. After selling both Trek and giant, trek is a superior bike.
Too much flex... Are you kiding???? (nm)deHonc

The new frame is stiffer primarily in BB area and the geometry is slightly different--the top tube is longer than Lance's 5500/5900 58CM frame. As for the Aero addition I don't have an answer.
Seat tube comment..usna00

I can't say much regarding your early points, nor can I actually say what the benefit of that seat tube really is... I have heard people say that the seat tube may be for aerodynamic reasons, maybe, maybe not...if it is for that reason, I can say that intuition and aerodynamics don't necessarily line up. Your 'common sense' analysis can rarely account for the vast complexities of the airflow around the seat tube or any other piece for that matter. So, your belief that the seat tube is too far from the wheel may not be may be true, but you can't really judge by looking at it.

Its hard enough to prove aero advantages given wind tunnel data given the large number of variables to consider (wind speed, yaw angle, test subjects..), thus its damn near impossible to judge 'aero-ness' just by look alone.

I'm not trying to be picky, I just think its more correct to consider things with the proper scope. If the seat tube isn't about aerodynamics then just please ignore me..
Trek carbon flexy? No waytarwheel

You're the first person I've heard of who has described a Trek carbon frame as flexy. My brother is 6'3" and 240 pounds and hasn't any problem with flex in his frame. What do you weigh -- 400 lbs?
Semi-compact remarks were scuttlebuttTrekFurthur

Trek itself never release that info; we got that from the most reliable of all sources--each other.

FWIW, my 5200 was no more flexy than my Merlin, which IS a compact--try the 5900--STIFF STIFF STIFF
Amen my brothas I said Amen !CARBON110

OCLV flexy ahhaha. I can't wait to see the 5900+ is what I was told its being called. I ordered one last month. It will be here in early Sept. i hope that due date gets better. From what I have been told by a few people, Teo you would be interested in this I will share with you later, is that its ""worth waiting for"" Anyone have a thought as to what frame Trek will also release this year? hehehehe

hint: its not "heavy" , its not steel, its available in all sizes unlike some OTHER bike companies, its not ugly, its not going to be out I don't think till August....did I mention I am seeing Bob Dylan tonight ?
OCLV frame too flexy???superdog

I haven't had this problem and I use mine to race crits with lots of speed changes and sprinting etc.

Might have something to do with the frame size. What size frame are you talking about? Mine is 56cm and no problems.
Flex testing on 5900 frame, and moreQuentinCassidy
May 14, 2003 1:01 PM
Cannondale's website has some tests which compare the CAAD7, OCLV 5900, C40 and Vortex against one another.... turns out the 5900 isn't too flexy, but maybe your 1200 miles were on a bad frame.

As for calling the new frame a gimmick, that's a little unfair. Sure it probably is, but many engineers would tell you that most features on your typical race bike (carbon stays, 1 1/8" headset, internal cable routing, etc.) are gimmicks... how else are you gonna sell 2 pounds of aluminum for $3000!
