Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

another fitting question

i've got a bike that's a little too small for me. just maybe half an inch in every dimension as a rough estimate. it's clear through what research that i've done that i should have a bigger frame. so, it seems to me that i can still adjust every dimension on the bike, even if it is fairly drastic. if i get a slightly longer seat post, a new stem to bring the bars up and out, and longer cranks, that satisfies every dimension but the saddle forward to back right?

so my question is, are there seat posts available that would move the saddle back the extra little bit?

and, if so, what would be the downside of an overly adjusted bike compared to one that's fitted completely perfectly? the only thing i can come up with is wheel base.

thanks in advance.

half an inch isnt that bad. You can do what you are suggesting easily with a set back seat post, it may not need to be longer neccesarily, longer stem. the cranks may be ok, depends on how big you are and what size on there now.
Down side? It may look a little funny. At a half inch I dont think it will bother handling or anything.

ok thanks for the response.

i guess i could have worded the situation differently though. i know that the bike is a little too small in just about every dimension, and the cranks are the easy part to change. what i feel like doing is making the change about 1/2" in every direction and seeing how it goes. i guess your answer takes care of that though. thanks again

Does the bike already have an offset seat post? If so, you're out of luck there, only option being a longer stem. How long are the cranks? I'd only worry about them if they are 170mm or less. Wheelbase isn't the issue with an incorrectly sized bike, comfort and handling are the issue.

Offset seatpost, longer stem, regular reach bars (i.e. 100mm+). Should be okay...

thanks everyone. it does not have an off set seat post right now. i've forgotten how long the crank arms are, but they're short enough that i run out of seat adjustment long before i'm close to passing the plumb bob test. i'll check later today. i want to say they were 165
