Uh Oh! Did I goof?

I posted my first thread here a few days ago. I was asking if it was okay to buy from another LBS if they carried a brand my usual store does not carry.
Long story short, I bought the bike. It is a WSD Trek 7.5 FX. I think I like it, but it has been hard to tell. I probably should have bought the 17.5 but got the 15. I rode it about 15 miles and determined that my seat was too low(causing tons of burning in my quads). I took it back to the store and they got me a REALLY long seatpost. I have not had a chance to ride it except for around the parking lot and stuff to tell if it is right. The reach feels right (which is why the one guy suggested I get this size). The seatpost probably sticks out 12-14" and looks a little strange. The other guy at the store said that he may be able to talk the manager into ordering the 17.5 for me.
I am supposed to leave for a 24 miler in about an hour or so. I want to ride it to see if it is right, but am afraid to ride it in case it is not. Based on what I have told you, would you probably take it back to the shop or keep it?
Thanks

Sounds like the shop you bought it from needs a new fit specialist...12-14" of seatpost???

Of course, I can't see you on the bike, but from what you just said it appears you need to take it back and get them to order the larger size.

If the fit feels right, who cares what the long post looks like. Your comfort is the determining factor. If the long seat post makes the bike feel right to you, I'd definitely keep it. The larger frame may cause you stem problems. Your $$, your choice!

I'd say that reach is far more important than saddle height. You can always, as your bike shop did, put in a longer post but shortening or lengthing reach is very difficult. The range of stems just isn't that great.

On the seat post; I ride mountain bikes a lot. My seat post is a very long 400mm or 450mm post that is just below the minimum insertion (about 2") in the frame. I have at least 12 to 14" of post showing. It's not that big a deal. Don't be afraid of riding it because of strength issues either. I know I outweigh you by a whole lot and I've never had a post fail.

100% agree. I bought a 15" instead of the next size up- because This size fitted me, The reach was perfect but saddle too low. Easy to change a seat post. fairly simple to change the Bar stem but if the reach is comfortable- this is the right size for you. Attachment shows my 15" frame as set up for me. I even put riser bars on to bring the bar a further 1" back. Incidentally- My previous bike that also fitted me was a 17" but this is better.

Thanks for the quick responses, guys. I should have mentioned that even with the outrageous seatpost, the saddle is still even with the handlebars. They said if it puts a lot of weight on my hands, I could go with a steeper stem. I think I will go ahead and ride it tonight and see.

Gotta agree with sabaka on this. I think that with a few exceptions, most bike sizing starts at some point with standover height. It's the one variable that can't be changed, and the one that usually impacts more geometry than any other. (lateral reach is usually a function of standover, as they increase and decrease in proportion with one another.)
Your reach distance to the handlebars with correct standover will often be correct, and if not is not grossly off, only an inch to an inch and a half in one direction or another...a fact that can be easily and cheaply rectified with a different stem.
I think it sounds like this bike was poorly fitted.

If your upper body and your arms are at 45deg to horizontal when you ride, it's probably fine. Stand next to or ride slowly past a shop window and look at these angles in the reflection.

You may be right, banzai, but the OP said the bike felt right. That leads me to think that his (her) torso is short in relation to the legs. If that's the case, then the smaller frame with a long post is exactly right. For folks with "conventional" torso to leg lengths, standover is a good starting point, but as Stuart said - top tube length is a better predictor of fit.

My legs are short in relation to my torso (the opposite situation that I posit for the OP). I, therefore, must either use a compact-geometry frame or a very long stem in order to have safe stand-over height. If a shop "sized" a bike for me by stand-over height only, they'd be off by a mile!

The OP may be in the same situation (and maybe not - the shop may just have sold him (her) what was in stock). I stand by my statement (and Stuart's) that having a long seat post extension beyond the frame isn't (in and of itself) a predictor of bad fit.

I'm not trying to discount what you say nor to minimize your opinion - I just wanted to add some info to the discussion.

That looks about like how much post I have showing on my mountain bike. Nice color by the way.

Thanks for all of your input everyone. I road it on the 24 miler last night. It was pretty omfortable, but had that nagging feeling the entire time that I had bought the wrong bike. When I called the LBS, the guy immediately asked if I needed the bigger size. He said they would order it and just swap the components. I think that is pretty awesome service!
