Try it again, but use the mountain bike calculator.

Bear in mind that your flexibility, weight and fitness level have a lot to do with bike sizing as well.

mountain bike fit calculator is oddly enough in the mountain bike section of the website.

There are 2 sections on the opening page. Click the one marked mountain bike and the "fit calculator" is on the top of the right hand side of the page.

i thought you were getting a bike from a LBS? The GT or Specialized? The LBS will fit you on your bike and get you the right size. Performance might not, but a good shop will.

Well I found a nice used 2009 Gary Fisher Pirahana for a sale somewhat local gotta drive a bit and the fram size is 19.5" well it says on the add but the L says its 19". So im wondering how will that fit me since its a steal for the price. Im not going with the GT's anymore, looking for a trek or a GF.

Any opinions? Will the 19" frame will be too big for me?

Fishers run longer at each size than most other mountain bikes. It's because of a slightly different attitude about frame geometry, and they're typically sold with shorter stems to compensate. Whether or not it works is a matter of opinion - some people love 'em, some don't. I'm certainly going to try to ride a few if/when I buy my next bike.

That said, the 19" has a 622mm effective top tube (that's 24.5 inches, for comparison with the chart that Colorado Cyclist made you.) Whether or not it fits you in reality depends on your flexibility and fitness level, but 2" is a pretty large difference. Call some shops. Try to ride 17" or "medium" bikes, but it's certainly worth trying a few in larger or smaller, if nothing else to know what a bad fit feels like before you spend money. IMHO, if you ride three bikes at your pricepoint and at least one too big and one too small, you should do fine picking your favorite.

First, in your price range there isn't much difference between the GT or a Trek/GF except for the warranty. But you're looking at used bikes now so warranty doesn't exist anyways. Don't narrow your search to one or two brand names. They are all similar at that price.

Now about fit, what Andrw said is pretty accurate. 24.5in tt would be stretching it for you unless you like to race and don't plan on any technical riding. don't buy a bike because of the deal, buy it because it feels good. No deal is great if you can't ride the bike.

Well went to my local Trek store tried the 19" trek then the 18" felt more comfortable on the 18", im leaning towards the GF Pirahna or the Tassajara. But damn it they did have any M(17.5") in stock in all the county they had to ship one from another state and it would cost me $100 extra. The 2010 Pirahna was at $699, they told me the 2011's should come out around August, asked the guy if they were more expensive cause they were newer. He told me he will let it go for the price of the 2010 that I was looking at.

FML no M's in all my local county, and ive gotta wait till August for the GF 2011's

I'm really confused... At this point, it sounds like you've tried the GT, the Specialized and a Trek, and of those, the 18" Trek felt like it fit. So why not buy it?

What was wrong with the GT? And why not ride some more Specializeds - the problem with your friend's was that it didn't fit, wasn't it?

Never tried the GT, the GT Avalanche 2.0 is around $600 and for the price I can get better components with a Trek or spending a bit more on a Gary Fisher.

Well the Treks I tried out was a 4300 disc that was L and a M 3900 with V-brakes, they didnt have any M's but the one I tried since the GF frames are pretty similar to the Treks. Th Gary Fisher Pirahna 2010 was marked down to $690 from $950 I believe but they didnt had any size in stock and there was an 2009 Pirahna in stock for $650 but it was XL. I asked for the GF Tassajara(its like $100 more than the pirahna) and they only had in L and there were no more in stock since the 2011 bikes are coming in August they told me.

They had M Pirahna 2010 in New Mexico but they they said it would cost me an extra $100 to have it shiped to the store. I told them that the 2011 Pirahna would cost more since it was new, but he told he when it came out he could let it go for the same price of the 2010 Pirahna which was $690. I hope that explained it better.

The GT 2.0 has much better components than the Trek 4300 disc and not as nice as the GF Piranha but that also cost $300 more. The GT 1.0 would be similar to the Piranha. I'm confused where you are getting your info? Trek is always more expensive for a similar bike. Thanks LA!!

The GT avalanche 2.0 was $600 at Performance Bicycle, I dont remember well how much was the 4300 disk but it was around $480 in the trek superstore I went too. For $650 I could get an 09 Pirahna with 27 speed hydraulic brakes and a rock shox Tora fork but it was XL, the 2010 was $50 more and I belive they had almost the same components. But they didnt had any GF Pirahna 09 or 10 my size so thats why I tested the Treks since the frames are the same I believe. They didnt have any Trek 6000's. So i just have to wait for the 2011 GF's to arrive.

If you can get the Piranha for $700 then get it, that's a good deal considering it retails for $930. I thought you were looking at all 2010's at retail pricing. Closeout bikes will always be cheaper but limited sizing.

Yeah they didnt had any 2010's piranhas in size M :\ thats why im bummed, they did had in stock in New Mexico but it would cost $100 extra. I told him how much will the 2011 piranha would cost more, but the sales guy told me he can let it go for the same price of the 2010. I said if I could order it but he didnt had an exact day they would come, so I would go there a by the end of the month to pre-order it so I can have a set price.

But man im itching for my new bike, when I tested the Treks out made me realize what a POS a vertical bike is lol.

There are so many different bikes out there, have you tried another LBS?
