CROWN RACE SETTING SYSTEM PARK TOOL CRS-1

The Park Tool CRS-1 is the professional system for installing the headset crown race on forks with a 1" or 1-1/8" steering column. Using the long, sturdy driver tube, one of the included drifts and a hammer or mallet, the race is driven evenly into its correct position on the fork crown seat.

The set includes six anodised aluminium drifts, three for the 1" standard and three for the 1-1/8" standard: the drift material avoids damaging the crown race while it is driven. The system works on steering columns from 25.4 to 28.6 mm in diameter, measured at the base of the column, and is compatible with SHIS sizes 26, 27 and 30. It accepts steering columns up to 340 mm long. A hammer or mallet is not included.

How the CRS-1 crown race setting system works

• Choose the drift that matches the steering column standard and the race being fitted
• Slide the driver tube over the fork steering column, with the drift against the race
• Strike the tube with a hammer or mallet until the race is fully seated
• 1" and 1-1/8" steering columns (25.4-28.6 mm) up to 340 mm long
• SHIS sizes 26, 27 and 30
• For oversized 1-1/4" or 1.5" columns Park Tool recommends the CRS-15.2
