Takeaways
Build note1:25Future Shock 3 restores home servicing, adds a damping dial from open to locked with five steps and takes different springs; it felt a bit firmer than the previous version.
Fit check2:06Clearance of 40 mm beats the Trek Domane's 38 mm and opens up light gravel events.
Ride impression2:55On 32 mm tires at low pressure it is far smoother than a Tarmac and was calm on wet, muddy roads and short cobbled sections; he left the shock open almost all the time.
Fit check5:12He dislikes the Hover bar's high front end and notes Future Shock prevents fully internal routing; it feels slower than an aero endurance bike like the Canyon Endurace.
