Question about Lemond top tube(7 posts)

Question about Lemond top tubenicholasdunford
Jun 26, 2003 12:04 PM
Everyone talks about how Lemond bikes cause you to be more stretched out than other bikes because of the longer top tube. I am confused about how this works, because don't you adust the stem to be in the most comfortable spot regardless? So if your top tube was longer, you wouldn't you just have a shorter stem? I am sure I am missing something here, that is why I am consulting the experts.

is everything else. If you are to look at just the TT length isolated from the rest of the bike then, yes, simply changing the stem lenth will allow you to find your reach. Unfortunately it's not that easy. It's all the other lengths and angles that confuse the issue. What's different about the lemond geo is that the TTs are longer in relation to the seat tube. Here's why that matters: If you took a rider with long legs and a relatively short torso and put him on whatever sized lemond gave him the best reach he would likely be on a bike that he would need to raise the seat to a level that would put his ass too high above his hands. When you boil it down you can fit most riders on most bikes (given a good choice of sizes) but lemonds are better suited for those with longer torsos. I'm one of those people who's shape doesn't lend itself to lemond type rigs but I'm sure I could get one to fit me. I'd be better suited to an Italian rig or something with that type of fit though.

Because of the shallower seat angle on the larger sizes,,some riders will move the seat forward some to get KOP. Lemond seattube is measured C-C and many other makes are C-T,so one has to compare apples to apples .As the other poster stated,the is more to it than just one piece of the geometry.

when Trek bought the brand. The propaganda about the lemond geometry is still written on the website, but the geometry tables indicate that Lemonds are not significantly different from a dozen other brands.

Go take a look at the Klein site. The geometry is very close for their non-compact frames.

Yes, Lemonds measure the ST differently, but so do others and ST length isn't that important except as it relates to standover height.

Lemonds do have a slightly longer TT and longer chainstay's then are typical, but I'm talking a 56.5 TT in a 56 frame size, as opposed to the usual 56/56 so it's not all that drastic and usually accomodated by a longer/shorter stem length - as it is with any bike. The chainstays are 41.5 which is slightly longer then usual and may make the bike handle differently, but I'm not sure anyone most folks would notice. Head angle is 73.5 with the ST at 73, which is pretty typical.

Lemond likes to think that his frames are more in line with the old style Euro racing bikes, but you'd need to go to a Heron or Rivendell to see that kind of frame.

Still, they are nice bikes. I've just put 500 miles on my Victorie and am very pleased with it. It does ride more like my Heron then like my Klein.

Lemond 56?Rusty Coggs

Where? I see a 55 and a 57,with the 56.5 TT belonging to a size 55. My Moser and Carrera 57s, measured C-C like lemonds have a 56.5 TT and the same 73* seat angle.
Typo !Steve Bailey

You're very correct and it was a typo based on a thought process that involved the Lemond ST measuring C to C at 55, which is close to a 56 frame measured C to T.

At least that's what my brain was thinking early this AM.
