I finally made a few more miles out with my Sirrus and realize that every bump, rock, and crack makes my bones jar. It's like riding on a metal roller coaster (not the smooth ones) that is stiff and rattling. It's aluminum with a carbon fork. The faster I went, the more stiff the bike became and even seemed to shimmy from side to side.

Is this a normal ride for aluminum/carbon fork frame and anything similiar to it will have the same riding properties?

While a carbon frame is lighter, will every bump be felt that much more?

I made 13 miles yesterday which is the most I've ever done and probably hit 25-30 miles going down a hill causing the bike to feel like it was vibrating from side to side. My computer went out a few miles after going..probably from all the rattling. I was doing regular highway roads, the ones I would be riding and if there's a better solution, it would be helpful.

I'm riding on ashpalt and concrete roads.

Now I know why you need cycling shorts. LOL. Glad I invested in a pair. Riding a couple of miles around the neighborhood is completely different than doing a 13 mile trip.
