Titanium Bicycle Tubing | Grade 9 Ti-3Al-2.5V Bike Frame Tube

Titanium Bicycle Tubing for Frames and High-Performance Builds

Beiyu supplies titanium bicycle tubing for frame building and high-performance cycle components. Titanium is chosen for bicycle frames because it combines low weight, good fatigue strength, corrosion resistance and a comfortable ride feel. Frame tubing is normally supplied in Grade 9 (Ti-3Al-2.5V), which offers higher strength than commercially pure titanium while remaining weldable and formable.

Bicycle tubing should be quoted by grade, OD, wall thickness, length and whether plain gauge or butted tube is required, because frame design and joint strength depend on these parameters.

Grade and Standards

Size, Wall and Tube Profile

RFQs should specify OD, wall thickness, length, tolerance and whether plain gauge, single-butted or double-butted tube is required. Builders should also confirm any tapered, ovalized or formed tube requirement and the joining method (TIG welding) so the condition and wall can be confirmed.

Common Applications

• Bicycle frame main tubes, stays and seat tubes
• High-performance and custom frame building
• Lightweight corrosion-resistant cycle components
• Other high-performance tube structures

Inspection and Documentation

Buyers can request mill test certificate, EN10204 3.1 documentation, heat number traceability, chemical composition and mechanical properties. Eddy current testing, hydrostatic testing or dimensional inspection can be agreed when defined in the purchase specification.

Packaging and Export Information

Bicycle tubing is protected against bending, end damage and surface scratches, with end caps and rigid packing for straight lengths. Labels show grade, size, heat number and quantity where traceability is required.

RFQ Information Needed

• Grade and standard: Grade 9 / Ti-3Al-2.5V, ASTM B338 / B861
• OD, wall thickness and length
• Plain gauge or butted tube requirement
• Tolerance, straightness and any forming requirement
• Quantity, destination and packing
• Certificate and inspection requirements

FAQ

Which titanium grade is used for bicycle frames?

Grade 9 (Ti-3Al-2.5V) is the common frame tubing alloy, offering higher strength than commercially pure titanium while remaining weldable and formable.

Can butted titanium tubing be supplied?

Butted tube requirements can be reviewed when the RFQ includes OD, wall profile, butt lengths, tolerance and quantity.

What is needed to quote bicycle tubing?

Send grade, OD, wall thickness, length, plain or butted requirement, quantity and certificate or test requirements.

Procurement Notes for Titanium Bicycle Tubing

Titanium bicycle tubing RFQs should define whether the tube is for frame main tubes, stays, seat posts, handlebars or custom frame components. Buyers should provide grade, OD, wall thickness, butted or straight-gauge requirement, length, tolerance, surface condition and whether bending, ovalizing, welding or mitering will be performed after receipt.

Grade 9 Ti-3Al-2.5V is commonly requested for bicycle tube applications because it combines useful strength, lower density and formability. RFQs should still define the required standard, heat traceability, straightness, wall consistency and inspection criteria. Packing should prevent dents and scratches because visible tube surfaces may remain exposed after frame finishing, brushing or polishing.
