I'm not gonna jump back in.... I'm not gonna jump back in...

...but I AM going to go ride some gravel here in about an hour. Buddy of mine keeps wanting to go out too effing early. Wait a bit and it won't be so bloody cold!

Nobody is suggesting that keeping records is a bad thing, what people find distasteful is all this 'dick-waving' by publishing them online so you you can brag about how well you've done.

Was that intended as a serious question? Because I shouldn't have to point out that in weight training, you can't simply pin an electronic device to yourself to keep the kinds of records weight trainers use. If anything comparable to Strava had existed for weight trainers, I would have gladly used it rather than going to the trouble of keeping records on paper.

Now on to your second contention. Maybe you'd care to explain to me why simply uploading your Strava results constitutes 'dick waving'. You do know that leader boards contain the listings of hundreds of riders for a given segment, right? If you understand that much, you can appreciate the absurdity in claiming that the guys who are not in the top ten are engaging in 'dick waving'. Unless of course you think the guy in 300th or 400th place posted those results in order to brag about them. So, suppose your criticism is aimed only at those who are in the top ten. Let's be generous and grant your groundless assumption that these riders posted their results so they can brag about them. It's an irrational assumption, but since your entire objection seems to hang on this point, we'll assume for the sake of argument that it's true. My reply would be, so what? Do you find it equally objectionable when racers post their first place finishes? What exactly is wrong with taking pride in being at or near the top in some personal endeavor? I notice that quite a few people on this forum post information about some marathon ride they've just completed, and that others aren't shy about congratulating them on their accomplishment. Does this offend you as well?

Crash-ability is exactly why I've never even considered CF, for a MTB. I can deal with scratches and dings, but, not the prospect of sending a CF frameset to Calfee, or somebody, for repairs/inspection. It seems like every crash I have is in rocks, which always result in some sort of new damage. Despite this video, I still can't accept it.

I've yet to see a CF toptube that didn't compress upon pinching. Furthermore, tube shape has a lot to do with the ability to do that; flat-sided shapes are more susceptible to it.

I know two local racers who have experienced multiple frame failures on their CF bikes. When they return them under warranty, they're given another frame just like it, which eventually also fails. They break in the same way and in the same locations as before, which points to a design flaw that the manufacturers, for whatever reason, have never rectified.

There are always going to be some model, from some manufacturer, that is going to have a structural issue (Gary Fisher Hi-Mod is an example). However, knowing the reputation of Niner (a small, dedicated company), that's highly unlikely, with their stuff. If you do have a problem, they take care of it directly. Furthermore, if you're out of the norm (clydesdale, lightweight, disproportianate, bomber, etc), it'd make sense to contact a manufacturer, before one's purchase. Despite looking similar, many manufacturers have models that are better suited to one's needs.

And

All that proves is there are 'dick-wavers' in any sport. I guess in this case, if they are juicing, tiny dick-wavers...

That's even stranger, because the top tube has to cope with compression forces coming from both ends, so the last thing an engineer would want is to flatten its cross-section, which would only make it that much more susceptible to buckling. I sometimes ride with a bike shop owner who happens to be the Niner dealer in my area, and I've seen just that kind of top tube failure on his CF bike. That one was a Scott HT though. He now rides a FS Niner. On his last ride, the CF seat post broke in two.

There are always going to be some model, from some manufacturer, that is going to have a structural issue (Gary Fisher Hi-Mod is an example). However, knowing the reputation of Niner (a small, dedicated company), that's highly unlikely, with their stuff.

Everything these days is designed and load tested by computer, using sophisticated software like Pro-E, Solidworks, Catia, etc. So I don't see why a small company would be turning out better engineered products than industry giants like Trek. Especially since the big companies have a lot more resources to enlist during development and testing.

Yeah you're done alright.

Go ahead, get that last word in.
