Regina Corsa for Frank the Welder

30 Year Old Regina Corsa Receives the full Spa Treatment

Regina, Mallard, and European freewheels in general, are sort of a hit or miss experience.  They can be a challenge to disassemble.  Their cogs don't like to thread off the body, and the retaining ring tends to remain stuck tight.  No matter how much the threads are soaked in penetrating oil, they like to stay together.

It was a real privilege to have Frank the Welder send me his Regina Corsa 5 speed for the full Spa Treatment.  Frank is a legend in the MTB world and is a member of the Mountain Bike Hall of Fame.  I was honored to see what I could do for his 30 year old freewheel he planned to use on a vintage Raleigh restoration.

Frank's freewheel could not have been more cooperative!  All but one of the cogs threaded off!  The retaining ring threaded off!  Out came the bearings, the pawls and the springs.  All the pieces went into the cleaner, and came out in great shape.

All of the Corsa cogs thread on to the body. Frank's 4th cog would not come loose. But all the parts cleaned nicely.

The pawls and springs cleaned and ready for 10,000 more miles of service.

Bearings greased, pawls oiled, springs installed, and ready for reassembly.

Frank will be pleased.  His Regina Corsa has at least 10,000 miles or 10 years before another Spa Treatment is needed.
