500 mile newbie Training/bike fit question
 

I got my first 500 miles in. I have decided to hold my weekly miles to 100 and add a pilates course to the program. I've been doing aerorbic training for 16 months and strength training for 5 months.

My question is "Will the pilates change the fit of my bike?" My hope is that by this summer I'll feel comfortable with a touring bike and sell my hybrid. At present I need an upright position to keep weight off my wrists (hands go numb).

Probably
 

but nothing to worry about. I found that Yoga loosened up my hamstrings enough to allow me to raise the saddle a few mm.

If your hands bother you, I'd spend some time adjusting the angle of your saddle. 1-2 degrees can make a big difference.

Saddle should be level or very close to it. If it slopes down you have to push back.

Make sure your saddle is back far enough. If it is not, then you have more weight on your hands. Yes, it is counter-intuitive, but you are basically balanced on your feet, hands and butt. If your butt is moved forwards, there's less weight to balance your upper body.

Last, the problem with flat bar bikes is that you only have one hand position. With a drop bar you can move to at least three different positions and some variations. That gives your hands and wrists a break since you use different muscles in each position. It really makes a difference on a longer ride.

You can get an additional position by adding bar ends to your flat bar.
