Great up grade to the stock stem

Stiff compared to my stock stem from my bike. I’m buying an 80 mm, the 70mm is short for me.

내 몸에 딱 맞는 스템을 찾았다 그거슨 역시 순정스템!!!

Easy switch from the stock 100mm stem to the 80mm.

The stem does actually fit 2018 Roubaixs- you do need the shim accessory that Specialized stores can supply. At first glance it appears to be too small to take the steerer of the Future shock 1.0 but that is because 2018 Roubaixs have a top hat style shim on top that you need to remove first.

The description isn't entirely true. You need an adapter that can only be purchased from a dealer for older Roubaix's (i.g. 2018). This really defeats the purpose of ordering one to your home and installing it yourself. Would be really nice if this were included in the fine print.
