Quill Stem with New Easton EC90 bar?
This may be a dumb question so please accept my apologies in advance.
I have just purchased an EC90 carbon road bar, 26.0. I have an older Trek 5500 with a 1" steering tube. I plan on upgrading this to threadless but in the meantime I'd like to use this new bar. Unfortunately, my current setup is a 26.4 Cinelli Grammo with a Cinelli Eubios bar. Needless to say, I can't use the Grammo. Can I use a 26.0 quill stem or I do I need to upgrade to the newer threadless setup before using these bars? Thanks in advance. Tob |

Tob For a definitive answer, just call Easton at 1-800-991-0070. I have found their phone tech support to be excellent. I have that same bar and when my postman delivered it, he thought the box was empty. ;-))) |

Tob Peter Chisholm answered a similar question for someone else in another post. Basically he said don't use a single bolt stem (a stem that is 'closed' and uses a single bolt for tightening) as the hole for the bar goes oval when the bolt is tighted and can partially crush the carbon bar in the process. If you use a quill stem, it should be one with a removable faceplate. As a temporary measure you could buy a stem column adapter, it allows you to use a threadless stem on a threaded fork Nitto, Profile and Zoom make them, not expensive. |

Tob I'm pretty sure the bar has no idea (nor does it care) what's happening 90-150mm away at the stem to fork interface. The bar clamp style used is more likely to be an issue, but even that I'd doubt to be an issue. One thing I'd consider - many companies also sell threadless converters: http://www.performancebike.com/shop/...e.cfm?SKU=1594 This way, you can just buy one stem (assuming you don't yet have one) and can just swap in a threadless stem when the time comes. |

I wonder why they don't put a piece of wood into the clamping area of a CF bar. I'm told that in early days, they did that with the steerer tube on forks so that when they failed, you had a chance to save yourself. |

How would you get it into the bar? I would only be possible with a straight
bar. Besides anyone using a EC90 is concerned about weight adding the wood would defeat the purpose of the bar, But this is a good idea for steering columns. cel "Paul Kopit" wrote in message ...

Thanks for the suggestion of contacting Easton direct. |

Tob You can use a 26mm stem but it MUST have a faceplatre. If you use a non face plate stem of any type, you will crack the handlebar. Threadless or not is not the issue, faceplate or not is. |
