okay im new to road biking ive really had a great time the last two weeks with my new hobby road biking,but my legs feel like jelly.i ride a mountain bike usually on the street for my cardio and im shocked that moving to a road bike could make my legs this sore.Let me share with all of you im learning the sram double click and i wad a in the wrong gears on big uphills that i had no business being on.i road flat 15 miles on friday and my legs are just tired.any advice on how to get my legs back or is it obvious i just need to rest.I had no idea how differently the legs react to a road bike as opposed to a mountain bike.should i raise or lower my seat?
