Hi guys

I have got a Cove Stiffee FR, at the moment I have got a Thomson Post on it, I want to put an Easton Post on it with some setback. I have an Easton EA70 Bars and Stem and want an EA70 post to match (sad I know), the EA70 post is available in 27.2mm and the Stiffee uses a 30.0mm, so I would need to use a shim. Are any of you guys using a 27.2mm post with a shim, if so any issues with it ? I am a big built guy so it is very important that I get this right. My other alternative is an Easton Havoc post which is available in 30.0mm. I know that the Thomson post is first rate but I do want to change to Easton. Any advice will be very much appreciated.

    Change the bars and stem to thomson :twisted:

    The EA70 post should be more than strong enough, I'd recommend the USE thermoplastic shims, great and very easy to use. The nice thing is that with the 27.2 post you get more flex and it will help take some of the sting out of the rear end of the stiffee which is really rather stiff!
