Thanks to all. I began riding a year ago 3 months after a kidney transplant. I rode the MS CITY TO SHORE 50 mile last year on a trek hybrid (nice bike by the way). I wanted to be more effecient and ride longer distances so I bought a Scattante Comp road bike. My legs love it. My arms and shoulders are another thing. Have had it two weeks and been on it 6 times 5 (7-10 mi) which were fine. Road into Philly and back (35 mi) and I was ready to cry. Legs....fine but the pain in arms and shoulders unbearable. Will I get used to this or could anyone lend some thoughts. Been reading about handlebar stems.
Any help would be greatly appreciated. Wanted to do the 75 mile this year for MS but am now concerned.

Thanks.
Bill

Hi Bill, did you get a bike fitting when you bought your bike? If not, that could be the root of your problem.

Outside of any fitting problems, you need some conditioning for the new position to be comfortable.
The low "racing" position takes some time getting used to.

It's also possible that you are working harder than you need to to support yourself in the new position (ie, you might be tensing up more than you should). Where are your hands? It appears that most people mostly ride on the brake hoods. Moving from 10 miles to 35 miles is a fairly big jump.
