Adjustable stem
Does anyone know how hard it would be to convert a Trek 7700
to an adjustable rise stem? I like the 7700 a lot, but I need a more upright riding position due to persistent neck problems. I would have the LBS do this at the time of purchase if this isn't a real difficult or expensive conversion. I have looked for a high quality comfort type bike, but they just do not seem to exist. I wouldn't mind having something that is even higher quality than the 7700 in this type of bike if such a thing was readily available. |

What are your complaints?? I would like the bar to be several inches higher than the seat due to spinal problems in my neck. I can't tolerate riding a bicycle very far when the handle bars are too low. I would like a lightweight bicycle with a more upright riding position that can handle a little abuse from riding on multi-purpose urban trails. The traditional comfort bikes are just to cheaply made and too heavy. I want something that I just haven't seen anywhere. Where I ride, there are quite a few wooden bridges that cross back and forth across a creek. That is why I want the suspension that comes on the 7700. I have a Trek 1200 that acts like it is about to break when I hit the seam between the pavement and bridge. I ride a Raleigh SC40 on this trail, but it is like riding a tank. I want something that is built really well, but a lot lighter. The Trek 1200 is great for riding on city street and came with a horizontal handle bar. I installed upright bar ends so I can rest my neck if it starts to get sore from riding in a low position. I could do this on the 7700, but I would prefer to install a riser. |

You might have to re-cable to get the height that you want. |

I'd still be using it, but I found a lighter and more elegant-looking Nitto stem that matched the settings that the adjustable gave me. FWIW, I've also become a possibly annoying advocate for the North Road bar, if you're not afraid of looking like a geek of my caliber: http://sheldonbrown.com/harris/handlebars.html (first bars on the page) They can raise the hand position up from that of flat bars, but regardless of how high they are set, they allow the wrists a more natural position than on flat bars, which in turn allows me to keep my elbows in, which in turn keeps my shoulders in a more comfortable position, which in turn keeps my back from rounding, which in turn relieves tension on my neck. YMMV. Folks will also point out that riding on the hoods on drop bars allows the same alignment benefits, and they'll be correct. Thanks to both of you for the assistance. I will have to talk this over with the bike mechanics at the LBS and see if they have the right parts to do this conversion. I am more concerned about getting a bike that is set up the way I want it than I am about the cost. |

I would like a stem and handlebar similar to what is on the Trek Navigator 300. I will talk the guys at the LBS and see how much trouble this would be. By the time I get done buying bicycles, I may end up with 4 or 5 instead of the 2 that I have now. There really isn't such a thing as one perfect bicycle for all uses. |

"I am more concerned about getting a bike that is set up the way I want it than I am about the cost." If you have the money, I think that is a great solution. I love riding my bike and getting the correct setup greatly improved the amount of time I spent riding. The stem is an easy fix and your LBS should be able to get you on the road quickly. You are also correct that once you get the bug new bikes keep coming home with you. |

The Nashbar Adjustable Stem allows variation from -20 to +40 degrees and is
solidly built. However, it does not adjust every five degrees. Mine seems to adjust every 15. Or maybe it's ten. It's not the graduated five degrees, I am sure. That's too fine a pitch. Or maybe I don't have the touch. Once adjusted, it is as solid as a rock. I should count those splines.... I use mine as a generator mount on the recumbent and another as a conventional adjustable stem on my Peugot mountain bike. The stem uses a sound, strong, four bolt handlebar cap which is milled out in the center and looks real spiffy that way. You might want something with a little more substantial cap for tough riding. Not that my handlebars have ever slipped with this stem. I think the hollowing out provides more of a tensioned stretch effect, and is as effective, compared to the clamping effect of a beefy cap. Actually, I think they spent too much money on the cap. But some buyers want that nice front look. The guts are really solid. It fits 1 1/8 with no shim, I think.... ftp://users.aol.com/DGoncz/Bicycle/ACMotorGenerator/ 08/06/2004 04:32AM 187,251 IMG_1701.JPG 08/06/2004 04:34AM 3,885,380 MVI_1702.AVI 08/06/2004 04:32AM 6,809 MVI_1702.THM 08/06/2004 04:36AM 1,617,920 MVI_1703.AVI 08/06/2004 04:32AM 6,868 MVI_1703.THM http://users.aol.com/DGoncz/Bicycle/...r/IMG_1701.JPG Just look at that ten pound 110 VAC ceiling fan motor core hanging from the stem! Dead weight is no problem for this hardware. It is available in three reaches. I use the shortest to reduce the lever arm on the dead weight. You'll probably want the longest, to provide maximum neck relief. Nashbar sells an extension, too, I think. Does the cubit rule apply to the OP, having neck problems, or would a more compact, upright posture having _less_ than a cubit between saddle nose and bar be most appropriate?
