To due


My friend, this is the exact thing to try and avoid. In the first part of your comment you said the seat tube length is irrelevant. Then in the very next sentence you say that an 18"-19" seat tube will give you the right geometry. I have had literally hundreds of framesets through my paws and have seen/built up/measured/ridden many same "sized" frames with completely different geometries and tube lengths. And it becomes even more important for you since you are trying to convert a drop bar which is already is designed to be ridden upright and riding it even more extended in the drops than your road bike that you ride on top of the hoods.* Yes, please transfer your numbers from your road bike and apply it to your drop bar MTN and I bet for the guys who are on here, who are truly in a comfortable position on both, those measurements are going to be scary close.




*damn that's a long sentence**
**is that even a proper sentence
