TECH Fork Spring
Suggested for 90kg+ Rider Weight for TECH 39mm forks with 39mm Alloy Tubes.
TECH 39mm forks can be found with both alloy and steel upper fork stanchions. Visually they are almost identical, but the spring used is different. Alloy upper stanchions have a thicker wall thickness, so the spring has a smaller ID.
Please check your forks before ordering. (use a magnet on the upper fork tubes to determine if they are alloy or steel)
The TECH steel 39mm forks can be found with upper stanchions with Chrome, black and bright GOLD finishes (like the TRS RR bikes - kick only)
The TECH alloy 39mm forks can be found with upper stanchions with black or "soft" gold finishes (GasGas, Vertiigo TRS RR with electric start)
Also available in Linear wound spring for heaviest riders LINK
