Sorry if this has been covered. I did a search and could not find it. Can anyone with a trek TTX tell me If you use a seat with long rails and turn the seat post around how steep can you get it? I have heard 76—79 but if you push the seat forward can you get to 81 degrees? If you do this are there any issues with the seat post holding? Are there any reasons not to do this?
Here’s a pic of my older TTX(56cm). Not sure about the angle-measurements, but I had the saddle push as forward as possible. I never had the post slip on me.
