Stronglight Headsets


Stronglight Headsets

Stronglight SA in Saint-Etienne France makes extremely high quality headsets. I had one on my racing bike when I raced in the mid 1970s. It was called the V4 and it had double the surface area for the ball bearings compared with any other headset available. Stronglight has always sought to make the most reliable and durable headsets without adding weight or expense. It's amazing what can be done with good design.

Bicycles come with a wide range of headset specifications regarding how the headset is attached to the frame and fork. And frames & forks are made in a bewildering array of dimensions.

For traditional bikes with 1" threaded steerer tubes, they make the A9, now with sealed cartridge bearings.

For standard 1-1/8" threadless steerers, we have the O'LightLX, the O'Light R and O'Light ST.

For Semi-Integrated MTB frames, we have the RAZ Carbon and RAZ Steel.

For 100% Integrated road frames we have Light'In Carbon and Light"In Steel.

For Mega-Oversized non-integrated lower bearing we have Light'In Mega Oversize and RAZ Mega Oversize.

To order, just call us at (603) 478 0900

Your local bike shop can also order these headsets from us since we are a distributor for Stronglight.
