Just got my first road bike. All I need is a seat
 

Hey Guys,

I just got my firs road bike (specialized Aleez pro). However, the bike came without a seat post, stem, and saddle. I could shop for the factory parts but I figure that I have the chance to get something good for me. Do you guys have any advice for what I should be looking for and what the difference would be? Additionally, specific models would be helpful.

Thanks.

You bought a bike without a stem? That's an interesting one. Are the handlebars just dangling off the front by their cables right now?

As for specific recommendations -- first you need to know the size you need. Not all seatposts are the same length or diameter.

Same goes for the stem -- there is threaded vs. unthreaded (the newer way), and the handlebar clamp diameter, as well as the head tube diameter. I'd ask the original owner if he has those dimensions available; otherwise, you're going to have to go measure (or get your LBS to measure for you). After that, you need to determine the proper length / rise stem you need to make the bike comfortable for you.

Once you have all that figured out you can begin to figure out which components you need.

stem-Ritchey WCS 4-Axis (Ritchey Pro to save a few $)
post-Thomson Elite (Masterpiece to spend a few $)
saddle-Selle Italia SLR if your butt can handle it (Performance Forte SLX to save lotsa $)

Thanks!

What size is the frame? What year is the bike? How tall are you? And some pictures would help. This is way more complicated than just buying some junk and slapping it together.

I'd go with everything here except for the saddle, specialized toupe. Just my .02

However, saddles are very subjective so you may have to try a few. The important thing about fitting the right saddle is the width. A specialized dealer should be able to measure your sit bones for you and thereby let you know the width you need.

I'd buy a few cheap stems first to see what length you want before forking over the big money on a permanent one.
