We can argue the fine details, but either way, the conclusion has to be SAFETY! :-) |

To a framebuilder, a complete boxed tube set is eleven tubes. Crap. Now I'm really confused. 2 seat stays 2 chain stays Seat tube Bottom bracket (or doesn't this count as a tube?) Top tube Down tube Head tube And optionally 2 fork blades Steerer So I get either 9 or 12. Which piece is optional? |

The old model had funny steering geometry, but no springs, and it was fine when I dropped the stem a bit. I was really liking the bike before it got swiped. Specialized also has the SCS (short chain stay) "technology" (i.e. incompatibility), so if you want to throw on OTC wheels from another manufacturer, you're screwed. With my old Roobay, I could swap a derailleur hanger, and that would allow me to use other wheels. The SCS technology was minimal on that bike. That isn't the case with the new through axle models. If I get a fast rain bike, it's going to be plain-Jane non-proprietary stuff. The Norco is like that -- to the extent that you can be plain-Jane with through axles. The standards are changing every ten minutes. I might just stick with the Norco -- or Oxy. There is a Norco epidemic you know. -- Jay Beattie. |

Good! It's about time you became cool. - Frank Krygowski The extra down tube makes it 50% safer than your regular bike. That's hard to quantify. If you look at tube sets over at http://www.cycle-frames.com/bicycle-frame-tubing/TUBE-SETS/ they come with nine tubes. Adding that extra tube would not add 50% safety, even if the increase in safety is not linear. But why would Jay stop at only a double down tube. There are also bikes with dual top tubes. https://s-media-cache-ak0.pinimg.com/originals/0f/3f/f0/0f3ff0c0c4818eed30add4c508e5727a.jpg. I've not seen a bike with dual top tubes AND dual down tubes, but I'm sure a custom frame builder could do something like that. I recall that there was one tandem manufacturer that put out a low end model without the dual downtube, and with standard diameter steel tubes and it was very squirrely. There are some newer models without the dual downtube but they use much larger diameter aluminum tubes to compensate. |
