So yesterday was a nice day. It was my birthday. And I haven't had the bomber (aka. my commuter) out since Thanksgiving. So of course the tires needed some air and dicovered my front tube leaked around the stem.

No biggie... took the wheel off and changed out the tube and I was on my way. Went for a 5-mile shake-out ride as I had made some adjustments to my fenders and added panniers since I had last took the bike for spin.

Anyways, got home and realized I installed a 700x23/28 and my bike takes a 700x32! I have a SS that takes the thinner tube and must have grabbed the wrong tube off the shelf.

So I guess today I'll swap the tubes out. Lesson learned.

Has anyone ever used the wrong tube and found out the hard way??

P.S.
Because I'm am cheap, I repaired the stem with Goop. has anyone tried this? The hole is exactly at the base of the stem and I've repaired lots of stuff with household Goop before. Thought it was worth a try. I might keep this tube as a spare of a spare.
