Thanks for the response
mel2012! Looking ahead, I'll probably be back in KY in a couple of years using a trailer and multiple kids so I think I've canned this option for something with more gears so I won't have to re-purchase.
When looking at new bikes, I've mostly been looking at quill but it seems that the stem on those has been 1 1/8 too. However I could be looking at the specs wrong. Do you know if new bikes that are quill stems typically fit the 28mm (1.1 in) specs for the seat? I am wanting to get a hybrid and not a beach cruiser so that I can ride faster when I am by myself. Thanks!
