We've built up 2 bikes that originally came with 1" threaded stems/forks. There are an abundance of 1" threaded to 11/8" threadless stem converters you can purchase for around $15. Our 2 frames came with sufficient length in the steerer, but not an abundance. I'm thinking we're going to go back and replace the original fork on one just so we can leave the steerer a little bit longer, but it's certainly comfortable enough where it is. Will matter if you're wanting to build up modern and like the look of a quill stem, or if you just want a bit more options to dial in fit. We have a 3rd bike, a Trek 5220 that also has a 1" threaded -17 degree quill that is ok to ride as is, but would be an awesome fit with at least a 0 degree rise stem, so guessing we will be doing a converter stem on it....already have the converter piece, just need to pick out the stem.
