Have fun finding a 25mm joint, i love my us tubes but it's s a bitch having a 25mm downstem, but that's weird the actual slide joint is 25mm, hmm
I want to take out the 24 mm stem and use it like a true natty. It sounds badass without the stem. My lhs said it would be hard to find, but gc kbows things.
I know you say it's 25mm but would a LW 28mm > 18mm 10 arm fit in there? If it does you could just get a 18mm slide and have an uber cool looking downstem.
