road bars/stems: safety vs. stiffness
it's been a number of years and a BIG number of miles, and i'm
starting to eye my old stem & bars (3ttt forgie & forma sl) with a little suspicion. they may have years left in them, but i'd rather not find out that's not true while pulling like hell to get up a hill. so...looking at what's out there now, i find that everybody seems to be pushing the 31.8 (or 31.7 if you're deda) stuff. and that causes my natural suspicion to kick in: if they're able to keep something with that diameter lightweight, how thin are the walls of the tubes? and while they're probably stiff as hell (as if i ever had a problem with my 25.4 or 26.0 bars) i worry that it might come at the cost of longevity and safety. they may be fine for someone who's (1) 150 pounds or (2) gets a new bike every year. but i'm closer to 200 pounds and replace my bikes every 20 years or so. so what's the, uh, skinny? what's a good, solid bar/stem combo that can deal with the miles without putting me at risk? or does that even exist any more? |

You should replace super lightweight racing bars once a year or so. Anything else should last for as long as the rest of your bike (unless you crash). |

Plenty of stuff from 3ttt, FSA, Salsa, Deda, etc. Just avoid the stupid light crap. Robin Hubert |

The bottom of the range from any of these big name brands will have plenty of good metal in them :-) Kinky Cowboy* *Batteries not included May contain traces of nuts Your milage may vary |

Any competent LBS which commonly builds bicycles to spec will have a range of sizes, shapes and styles at hand. 31.8 to many of us seems just another (expensive) gimmick. It is on no way essential and may easily be avoided/ignored. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

What counts as "super lightweight racing bars"? Are you thinking of
carbon fiber only, or aluminum too? I'm just wondering cause I'm relatively new to racing... I'm using an old 1990 ITM stem that *appears* to be in great shape, and some Nashbar ergo bars that weigh 242g. I shudder at the thought of a stem/handlebar failure... Dan |

Few things to consider: A) OS bars are generally a bit heavier than the same, non-OS bars. Check the mfgr stats. So they haven't gone nuts on wall thickness. B) Keep in mind that the OS part is actually pretty short, while the rest of the bar is the same as non-OS bars. C) Anyway, the wall thickness wouldn't really affect how they hold up from daily use, for the same reason a large-tube, thin-wall 3lb aluminum frame will outlive an older small-tube, thicker wall 3lb one, at least as far as not breaking from normal use. Thin walls do become more prone to localized buckling from impacts, but that's mainly in much bigger tubes than bars. That's why you tend to see more small dents in modern AL bikes than back in the day. Bike falls over against a sharp corner and there you go... Bars are much less vulnerable to that sort of thing, and stiffer ones will hold up longer under normal pushing and pulling. D) Bottom line, if you've been doing OK with Forma SL's you'll be fine with OS bars in the same weight range. And there's a wide weight range of OS bars to choose from. SB |
