Carbon Fiber Tube Size Chart
This is every round carbon fiber tube size we keep in stock, listed by outside diameter. Use it to find the bore you need before opening a product page.
Three numbers matter. OD is the outside diameter — what the tube measures across the outside. ID is the bore — what has to fit inside it. Wall is (OD − ID) ÷ 2, and it is what actually decides how stiff the tube is: the same outside diameter with a thicker wall is a stiffer tube, and a thinner wall is a lighter one.

What is not in this table
Not every bore is stocked in every length, and the longest sizes are not always in stock. The product page for a given OD shows exactly which combinations are available right now — the chart above tells you where to look.
Lengths other than the ones listed are cut to order. Bores outside the range shown, larger outside diameters and custom layups are made from 10 pieces; send the outside diameter, bore, wall or length you need and we will quote it.
