I don’t know but why is it that with my commuter I feel that I need to put less effort in order to go fast vs my Aluminum more aggressive road bike?...I also feel that I need to spin faster to go up hill than with the commuter….. I workout my thighs more with the aluminum than with my steel bike .. or at least that’s how I feel…..is this normal?... my thighs feel more sore after I ride the Aluminum . Does the aggressive position has something to do with this, the size of the tires or flexibility of one frame vs the other? Or it could be the pedals?...I have dual sided clipless on the commuter and I use the flat side which have a very good grip and my shoes almost never slip from the pedals even if they are wet…with the new bike I had to reposition my feet several times on Saturday's event . I have been commuting with my Schwinn for a while now and I am very use to it and I really love that bike. I am pretty sure I could go for at least 45-50 miles with her easely without more complaints than normal. I want to be able to do the same with my new Roadie. I use the new bike twice a week ..on Fridays to go to work (20miles total) and on Sat or Sundays for whatever miles I can get. Should I start using it more often and for longer rides to get use to it?... I love to use my Schwinn as a commuter because of the smooth ride and she can take a little bit of a beat up on rough roads+ I have the rack and bag where I can carry my stuff. On the other hand I really don’t want to expose my aluminum bike to the harsh of the bad roads but I do want to get a bit more miles with her to get use to the frame position , Saddle etc etc and also to get ready for my next 50 miles event in Sep.

Any thoughts?...

Thanks
