I have a new 2020 Specialized Di2 Roubaix Comp with the Future Shock 1.5 fork. My problem was that I was unaware of the extreme limitations of using spacers (or any method) to raise the bar height. I am coming from a 2007 Roubaix which I used spacers to adjust to a perfect fit the bar height. However, despite using every technique that I am aware of I am still about 25mm (~ 1 inch) too low which creates significant shoulder and neck pain for me. I have put on an adjustable stem (like my 2007 Roubaix) and have adjusted to about 30 degrees (do not want to go more for steering control issues) and lowered my seat some to compensate but still not there. The Specialized Future Shock manual indicates you can add up to 15mm (max) of spacers directly on the proprietary cartridge under the top cover. To make matters worse you are limited to any stem with a steerer height well of 40mm which means any fixed stem angle is limited to about 17 degrees as any stem with steeper height interferes with the installation of the proprietary top cap. You cannot use any standard replacement cap and bolt. I talked with my Specialized dealer (LBS mechanic) and he said he was not aware of any way to raise the bar height using spacers with this model bike and he has never added spacers as indicated in the manual (was not even aware it can be done). Other bike shops (non-Specialized) won't touch it as it is so proprietary and my bike fitter, I get the feeling is not as knowledgeable on this as I would want. So my question is have any of you tried raising the bar height on this model bike with the Future Shock fork (2017 -2021 model years I think) by adding spacers or any other method? Thanks.
