I was just wondering... because it seems like I'm usually in the small ring, with occassional bouts of the granny gear in the hillcountry... A riding partner of mine always seems to be in her big ring, even going up some hills, and she's always having to wait for me to catch up Do I just need to start riding in the big ring on flats to build up my muscles?? I'm confused because that seems to be contrary to the concept of spinning...

thx

oh, p.s., this is all on a road bike.
