Wanted: Quill stem, 26.4 clamp

im using a tiny stem on my bike at the moment.
but no, im not sure i need 90mm, ridden a lot on my mates bike with a 90mm nitto pearl and it feels nice but i must admit i havent tried anything else

your mate bike may have a different top tube length that's perhaps shorter or longer than your, which also affect the reach as well.

A Nitto Pearl 9 is realistically 100mm, not 90mm as expected (Nitto measure it differently).
