    I bought the wrong frame size...

    I have a 2008 cannondale f5, which I bought off craigslist used.

    It was a good deal, so I overlooked the slightly incorrect size.

    As I get into riding more, I think it may actually be a serious impediment.

    So, here's my question, how much will the frame hamper me?
    I am 6" and I have a medium size frame.

    Here's a link to the geometry.

    I know large would have been a better choice, that wasn't my question.

    If you already bought it, try it. If you have not bought it, don't!
    Set back seatpost and xl stem may help.

    At least , a poor fitting frame will probably not get ridden very much .

    I have already purchased it, and seeing how I don't really have the money to replace the frame, then

    Are there any adjustments I can make (other than seatpost) to make the bike more comfortable and better fitting?

    EDIT: And yes, I ride the bike about 5-6 hours a week

    It will feel good going down hills, it will feel miserable going up hills. On long rides, your back will stiffen up and remain that way for days afterward. A long stem will do nothing but ruin the handling. Also, frames sell for almost the exact amount full bikes sell for. Sell it to a friend and start all over. (I did the same thing and ended up giving mine to my wife) On the plus side, you get to go bike shopping again.

    As Yogi Said, Set back seat post and a longer stem.

    The medium is a 16". This is what most manufacturers spec as a small, this is not a "slightly" incorrect size. Usually a medium is a 17" or 18" Basically I am saying that you have a size small bike for a large person. If you ride it as is, you will not be able to get the seat up high enough which means you wil mess up your knees, and you will be really cramped. As mentioned already your only soultion is a longer seatpost and stem which will mess up the handling of the frame big time. But if you are a noob you most likely won't notice.

    Bike fit is the most important aspect of a bike. It is no deal at all to buy an ill fitting bike regardless of the price.

    Maybe but if he's not going to spring for a larger frame/bike there's not much else to do.

    The LBS I bought my bike at fit me to the wrong size. I am 5'10" with a long torso and they put me on a 17". I never really noticed it until almost a year after getting started, I thought being that uncomfortable was normal. One day I started to question the size, so I went to the LBS in the area I moved to and asked about the size. He did a full fitting on my bike, and it ended up being way too small. I ended up ordering a 130mm stem and setback seat post. It helped a good amount, still not perfect though. If you are not in a position to be buying a new bike/frame right now, do what I did, have a LBS do a fitting for you and order up a new stem/set back seat post, it's better than nothing. Hopefully next year I can get a new bike, or at least a new frame.

    Here's another option:

    http://www.pricepoint.com/detail/195...lloy-Frame.htm

    Switch all the components over (seatpost and front derailleur may not swap) and sell the frame.

    The other thing you will have to double check is the steerer tube length on your current bike. If it doesn't fit (i.e. has been cut too short), you would also be looking at a new fork. This may take this out of the realm of a bargain fix, or you may decide to do it and get a much nicer fork.

    You could do almost the whole job with a handful of hex wrenches and screwdrivers, the bottom bracket and fork swap you should be able to get a bike shop to do pretty cheap.

    My girlfriend (~5'3") has an '08 F5 in "small" and it is very small.. Definitely much smaller than the 16" GT I have, which is equivalent to a "small" in current GT and other bike manufacturers. I'm a short guy (5'7") and the small F5 seems tiny to me, I can't imagine trying to ride a medium frame if I was 6'.

    Since you got a good deal on it, sell it and start over.. It's a nice bike and you should have no problem finding a buyer if the price is right.

    A medium has an effective top tube of nearly 60cm and only a half degree difference in seat tube angle between it and a large (their chart is farked up and juxtaposes STA and actual TT). Unless you've got gorilla arms, incredibly short legs or a really long torso @ 6' I'd say a medium is just fine. Many people intentionally buy slightly small frames because they want a lighter, quicker, easier to flick bike. I don't see this size as being out of range at all. Pay no attention to the seat tube size. It has little to do with sizing the frame as long as stand over height is adequate, which there is plenty of for this bike.

    For comparison, my 19.5 Felt RXC Team frame has an effective TT of 62cm. The 17.5 has an ETT of 59cm. I'm 6'2" and of normal proportions and the 19.5 fits me like a glove. At 6' you should fit fine on a bike with a 59.6cm ETT.
