quick tire question
 

What is the equivalent 700 C tire size to a 27" by 1-1/4"?

700x??

I think he means width. 32 or 28.

yeah, to clarify i wanted to know witch width of 700c tire was closest to 1-1/4"

1.25 inches times 25.4 equals 31.75mm. But as some of you know sidewall numbers are not accurate. Its true for bicycle, motorcycle and car tires. Its just an estimate.

Google search's automatic calculator is good for this. Search 1 1/4 inch in mm = 31.75 mm
