Hi…please go easy as I’m not great with this stuff….I have a specialized sirrus sport and I now have the inner tube where if there is a puncture it doesn’t deflate…recently I’ve noticed that going over any bump in the road,pavement crack etc I really feel it from the back wheel…even if the crack is vertical it seems to slip on it rather than go smoothly and if horizontal where it was smooth over it so that it is barely noticeable now I feel the bump….I wanted to ask you guys first before taking it to the shop…could this be the tyres or a suspension issue ..I’m sure I’m not imagining it…it’s almost like the trees are deflating but they are pumped properly

many thanks

Check installation is correct.
Take out the liner, ride and see is it better.

Do you have air in the tube? If so, what PSI?

If you are saying you put a puncture proof tube in the tire, then those tend to not give a good ride even when they are at their best.
