Did I goof?

I wanted to try a different stem so I ordered one from Jenson today. I measured my handlebar with calipers and they measured a tad more than 25.8 mm..... I ordered a 26mm. Can anyone tell me if the 26mm stem will work OK, or is it going to be too loose?

Perhaps I'm missing something but isn't a tad more than 25.8mm about 26mm?

Is your bike a road bike? A lot of modern road bikes (let's say 2002+) use 26mm handlebar diameter so your should be fine.

Yes, 2002 road bike.

By a tad, I meant 25.83. My cheap calipers could prolly be off more than a tad.

Considering my calipers don't have a mark for a tad more than 8/10's of a millimeter, I'm assuming your existing stem/bars are 26.0mm, and you are just trying to force your calipers too much. You should be fine . . . did you measure both the inner diameter of the clamp and the bars, did you reset everything and re-measure?

Also . . .

I think the OP meant that if the stem clamp is 26mm and his bars are 25.8, then they would be loose, because the clamp would be bigger than the bars.

They are digital calipers and usually pretty accurate. All I measured was the handlebar right next to the stem/clamp. I didn't even loosen the clamp. The bar is the same size out about 1/2" from the stem as it is in the center. Sounds like maybe I will be OK.

0.2 millimeters = 0.00787401575 inches

Kind of puts things in perspective, doesn't it.

I doubt the manufacturing tolerance of the parts is even within +/- 0.01"
