I'm just getting back into bicycling since the mid 80's and picked up this Gavin Solo. It's pretty light and smooth riding. I'm 5'9" so I ordered a 54cm frame but I have the seat all the way back and I still feel a tiny bit cramped. I'm guessing I could swap out the stem but I'm new to road bikes. The stock stem is: "Tec9 25.4 60mm 0 degree Silver Alloy". I don't want to get the wrong size so if someone could give me an idea that would be great.

judging from the photos i've seen, it looks like a 1 1/8" threadless... and i would say a 26.0 bar clamp size... but the 25.4 throws me off... i didn't think anyone made anything in that size anymore?

i think you will be hard pressed to find another stem that is a 1 1/8" steertube clamp and a 25.4 bar clamp... but if it's actually 26.0 then there are a lot out there. the 60mm is the actual length of the stem, so you'll want something longer obviously

(pardon any Noob terminology)

Thanks. Yeah, it states the fork tube is 1 1/8" threadless. Since I have the seat all the way back, what size do you think would be a good choice? I also see there's angled ones too.

I have my bars setup exactly like this:
