Product Details

Overview & technology

FSA The Pig is a BMX- and downhill-ready external threadless headset engineered for durability and precise steering under heavy loads. Part number 141-1005 features a mix of oversized lower bearings, a forged and CNC-machined chrome-moly (Cr-Mo) lower cup, and deep 12mm cup seats to maximize bearing support and longevity. The headset uses caged ball bearings — 5/32" x 22 caged balls up top and oversized 1/4" x 15 caged balls on the lower race — giving a robust contact area that resists deformation from jumps, drops and hard landings. At just 120 g and a 29mm stack height, The Pig balances strength with a compact, low-profile fit ideal for aggressive setups.

Key features & benefits

Materials and construction: The lower cup is forged then CNC machined from Cr-Mo steel to provide high-impact resistance where you need it most. Both upper and lower cups are 34mm ID with a 12mm deep cup seat that protects bearings from contamination and improves load distribution. Bearing tech and real-world advantage: Caged ball bearings reduce internal friction and keep the bearing balls evenly spaced under load, which helps maintain smooth steering after repeated hits. The oversized lower 1/4" x 15 caged bearings increase contact area and durability for landing-intensive riding.

Fit, sizing & compatibility

Standards and fit: S.H.I.S. specification is EC34/28.6 (upper) and EC34/30 (lower) for 1-1/8" straight steerer tubes — the common setup on BMX, dirt jump and many freeride/DH frames. Crown race diameter is 30mm and the lower cup OD is 34mm; stack height is 29mm. This is an external, threadless complete headset that installs in frames designed for EC34 headtube shells. Available in Black and Silver finishes, The Pig fits most modern 1-1/8" steerer forks that accept EC34 cups and is best matched to frames listing EC34/30 lower compatibility.

Who this headset is for

The Pig is aimed at BMX riders, dirt jumpers and gravity-oriented cyclists who need a compact, tough headset that keeps steering crisp after repeated impacts. If you ride aggressively — jumps, park laps, pump track and bike-park runs — you’ll benefit from the oversized lower bearing and Cr-Mo lower cup strength. It’s also a great upgrade for riders switching from cheap press-fit headsets: you get better bearing retention, easier serviceability and a stiffer lower cup that handles heavy landings and high torque without giving up weight advantages.

Frequently Asked Questions

Will The Pig fit my frame?

If your frame uses S.H.I.S. EC34/30 lower and EC34/28.6 upper (common on BMX and many dirt jump/DH frames) then The Pig will fit. Confirm your headtube shell spec or check your frame manual; the headset is for 1-1/8" straight steerers.

Are the bearings serviceable or replaceable?

Yes — The Pig uses caged ball bearings which are serviceable and can be replaced when worn. Caged bearings are easier to handle during servicing and resist ball misalignment under load.

Is this headset weatherproof for regular park and outdoor riding?

The 12mm deep cup design and steel construction help keep contaminants out and withstand moisture and grit better than shallow-cup alternatives, but regular cleaning and grease maintenance will extend bearing life under wet, muddy conditions.

Can I use The Pig on a tapered steerer fork?

No. The Pig is designed for straight 1-1/8" steerers with EC34 upper/lower specifications. Tapered steerers require a compatible tapered headset or adapter specific to your fork and frame.

How durable is the Cr-Mo lower cup compared to aluminum cups?

Cr-Mo steel lower cups are tougher and more impact resistant than typical aluminum cups, so they deform less under heavy landings and hard use. The trade-off is a small increase in weight versus some lightweight aluminum options.

What is the correct crown race diameter?

The Pig uses a 30mm crown race diameter, which matches many 1-1/8" forks. Always verify fork crown race specs before installation to ensure a proper fit.

Buying Guide

When selecting a BMX or dirt-jump headset, prioritize tolerance to impact, bearing size and cup depth. Look for oversized lower bearings and deep cups if you regularly jump, land hard or ride park features — those features increase contact area and protect bearings from shock and contamination. Match the S.H.I.S. spec to your frame (EC34/28.6 upper, EC34/30 lower for The Pig) and verify crown race diameter. Decide if you want steel (Cr-Mo) lower cups for strength or lighter aluminum options for minimal weight; The Pig favors durability for aggressive riding.
