First off, nice to see that this forum even exist. :-)

I plan on purchasing a Trek 1000 WSD and was told by my local bike shop mechanic that a size 47 frame would suit me best. He came to this conclusion fairly quickly, glancing at me, and then having me sit on the bike for about 5 seconds.

Not that I'm doubting his expertise (okay, so I am), but I was just wondering if you all think a size 47 frame would fit someone who's about 5'5, weighs about 125, and has normal size limbs?

Thanks for any help and for your time.
