Is riding with a bent seat post just asking for trouble?

It was bought from some 3rd party by RTC. I agree with earlier RBT comments, that the cheap seat post, combined with the frame angle, with my 210lbs rider weight + 20 lbs backpack, simply will not work. Physics 101. J. don't ride it. and as chalo says, a rack is great idea in this situation. |

I had best not mention shoes. I think I may have more bikes than she has pairs of shoes. (Maybe. It might be closer to mere parity, but that's still not a good thing to use as an example.) Now, I could make a case for SF and fantasy art prints; she's got more of those than we have wall space to hang them. You're lucky. Thanks to my ridiculous collection of bike-specific shoes (four pairs; three in active service) I have more shoes than my wife. Oh, you can imagine the dinner-table conversations! As for bikes, well...I'm pretty sure she doesn't know about the horrible Raleigh I just dragged out of someone else's trash pile tonight. Heck, she has no chance: it just went into the pile of about 10 other project/sale bikes I have sitting outside of my two backyard sheds which contain the "good" bikes. Yeah, I have a problem. Here's a little checklist: http://www.indiana.edu/~adic/checklist.html I substituted bicycle/riding for alcohol/drinking, and scored an 11. "Scoring: If you noted three or four of the statements you should be suspicious about the way you use substances. If you noted five you may have the beginnings of a problem and perhaps should start looking for some kind of help. If you noted more than five, it would probably be a good idea to talk about your use of substances with a professional counselor." -- Ryan Cousineau http://www.wiredcola.com/ "In other newsgroups, they killfile trolls."

I have decided to not ride the bike as it is. I have pulled the seatpost off, and I will carry it to RTC, bring the new seatpost back to the office, and install it. The markings on the seatpost indicate it is a '27.2E Kalloy' silver seatpost, which sells for ~ $18 USD. I think the RTC sales person bought the cheapest extended seatpost she could find, without asking the mechanics in the shop for their opinion. She originally did not order an extended seatpost at all, even though we discussed this in some detail during our earlier phone calls and emails. J. |

Chalo I am very glad to hear you say that, Chalo; Because othewise, it would mean my Electra was a huge mistake for my load and height. This would also mean Andre was misguided in his Electra suggestion. I just don't think so. I am commuting on city streets. Never jumping off curbs, or anything of the sort. I'm the same weight, I have my seatposts out as far as yours, and I jump off kerbs all the time, and ride onto them too at speed, just lifting up on the pedals to shift my weight with the bike. And my seatposts are suspended items, which makes them even more fragile. My seatposts are Post Moderne and Kalloy. The first Post Moderne was wrecked by the LBS stripping the threads in the head in angling the seat. After reading of your problem, I've inspected the seatposts on both my Dutch city bikes and they seem okay. It's not you, it's an inferior seatpost. I have decided to not ride the bike as it is. I have pulled the seatpost off, and I will carry it to RTC, bring the new seatpost back to the office, and install it. Probably the safest thing to do. Though I must say, my experience with a broken seatpost, taken secondhand, is that the guy it happened to was still mobile and the next day continued on his tour of Ireland. I told the story here befo I found this guy on the pavement in front of the library, waiting for me by my bike to ask for directions to the LBS. He'd broken the titanium seatpost on his touring bike. I had a post I could give him so I took him home with me; the steel post didn't fit, the LBS had nothing he wanted, so I called around the bike shops in the city and the next day the guy picked up a new post. Thing is, he was a physician and knew how to describe what had happened, and while he was bruised, he wasn't bleeding or crippled or anything. He was a little pale but no more than a guy who has just taken a long ride on a new Brooks saddle. The markings on the seatpost indicate it is a '27.2E Kalloy' silver seatpost, which sells for ~ $18 USD. I think the RTC sales person bought the cheapest extended seatpost she could find, without asking the mechanics in the shop for their opinion. She originally did not order an extended seatpost at all, even though we discussed this in some detail during our earlier phone calls and emails. I'm really rather disappointed in a shop that everyone recommended so highly. This isn't just a stupid, careless and greedy mistake, this is potentially dangerous. Furthermore, I think two paradigms are being thoughtlessly compounded here. A guy who buys a Dutch city/sports for well over a grand for the stated purpose of long-term all-weather year-round commuting clearly wants the best, defined as the most reliable parts. He is most definitely not a weight weenie. Everyone in cycling knows, or should know, that Cheap + Low mass = Unreliable. I conclude that if you're trying to save a buck -- which I know you're not, but for the sake of a complete argument -- you should have a good steel seatpost, not a cheap alloy one. If you're not trying to save a buck -- which we know is the case here -- the mechanics would have told her on request which alloy seatpost has the reputation of lasting even in offroad abuse (as Chalo says), except she clearly never asked. In your position, I would say something polite but pointed to the owner of this LBS, starting with the words, "I came here because you're highly recommended," and ending with a pious expectation of dealing in his shop in future with someone more experienced than the person who made "this reckless and potentially dangerous mistake".

There are cheaper and crummier posts than Kalloy, believe it or not. The fact that it failed is not terribly suprising, though. The brand is adeaute for the purpose for which it is most commonly sold; as a post for a mountain bike. Kalloy's been around a while, but the proliferation of slack-angle frames that might need a long extension on the post is a situation that's been building; I suspect the word will get out that Thompson's the only reliable way to go for that app. -- My email address is antispammed; pull WEEDS if replying via e-mail.

I don't think failure in this particular case speaks poorly of the Kalloy. Judgement on the part of the LBS in installing it is a different story. Joseph |
