safest stem?
What would be the safest threadless road stem out there, with a face plate
so you don't have to remove the shifters etc? Of all the bike components, I always look at the stem as the most scary, as a failure would be catastrophic. I've seen lots of metal sh*t break that looked a hell of a lot stronger than a bicycle stem, thus the paranoia. I've ridden around a 100,000 miles and never had a failure, and I have had two bolt and 4 bolt stems, and never a failure or a crack in any of them. But is there such a thing as a fail-safe one, with the specs I listed? |

Salsa makes a steel threadless stem that costs about $40USD. Very nice stuff. Then again, I've got a stupid amount of miles on aluminum stems without failure. Maybe I'm just not man enough to wrench it apart. :sigh: |

But is there such a thing as a fail-safe one, with the specs I listed? So, you have all this personal experience with the reliability of these stems, but yet you are paranoid about them braking? Yes, I know that stems have been known to break, and sometimes without the rider being aware until it failed catastrophically. But this is a rare occurrence. Certainly seat post failures are more common, and painful to contemplate. Are you as paranoid about those? Forks can fail, cranks, etc. Usually there are warning signs, if you will look for them. Do that, or give up the sport as being too dangerous. I sincerely doubt that there is a single stem that is unbreakable. Yes, steel would be less likely to fail without obvious warnings, but then you should also use steel cranks, seatposts, and forks by that logic. Certainly cost does not correlate with failure risk, in fact some of the most expensive are expensive precisely because they are lighter, hence weaker. Stuff happens, but it happens less if you watch for signs of cracking, and listen for new creaks and other unusual noises. And yes, a broken stem can cause a fall. But you can fall with a perfectly sound bike as well. Relax and enjoy the ride. -- David L.

Probably something sexy and practical like this, available from any local bike shop with a QBP catalog: http://harriscyclery.net/page.cfm?Pa...ils&sku=SM9252 /sarcasm |

Without that one bolt failure leaves the bicycle with a detached handlebar. In other words, neither steering nor brakes. Not a recoverable situation considering that such a bolt failure would be occurring at a stressful instant. Jobst Brandt |

Slender and not much taller than me...but massive legs. He also lives off of coffee, candy, and the occasional beer. *** off topic: While I got your attention, what's a good and fairly cheap place to grab eats in Atlanta that's got some local flair? I'll be passing through this spring and staying over by that new IKEA store. Ah, my old side of town (still where I commute to everyday). Traditional southern is nice, but if there's international cuisine of merit in the area, that's my cuppa as well. Hole in the wall sorta place is preferred, and if it's just a shack with a window and a Coke machine then it'll likely get 5 landotter stars! I'll eat anything from decent vegetarian (hold the sprouts) to pork cracklins. Trad. Southern: -Bobby & June Country Kitchen on 14th St between Mecaslin St and State St (this is right next to Atlantic Station/IKEA) -Son's Place at Hurt St and Decatur Ave Vegan/Black Hebrew Southern: -Soul Vegetarian No. 2 on N. Highland between Ponce de Leon and North Ave (a little pricey, but good!) *Authentic* _Cuban_ sandwiches -Kool Korner's on 14th and State St (*hole* in wall, take out only, but damn good at $4.70 a piece after tax). As a last resort, go to Eat's on Ponce. Bobby and June's is probably right up your alley and damn close to where you'll be. The hours are shifted kind of early (6am - 2pm?), so you definitely need to be there by not long after "lunchtime." It's pretty busy, but you tend get seated fairly quickly. I prefer Son's personally as it's more 'Soul' food than 'Southern' (shades of gray, really), but much less convenient to find. Also, if you end up spending too much money at IKEA, eat there. It's dirt cheap and pretty alright too. Shame I won't have room for a bike in the car, I'd have hooked up with ya for a fixie tour de 'lanta. Five people in a Jetta, this should be fun... Question: how are you going to be getting anything home? I'm a student a GA Tech (a few blocks from AS/IKEA), drop me a buzz off line for a phone number if you get lost/whatever.
