saved me a lot of money in the long run
"I recently switched out my cockpit on my TT bike. sadly i had to remove the aero stem to get the comfort and fit that I needed. The original aero stem allowed me to fit the hydration system from Profile design. when I removed the aero stem I though I would have to use a less aero hydration system. Then I cam across this little beauty. I ordered the 1 seventeen stem and was able to add the hydration system once again. The price was very good"
