Review on Campagnolo Freehub Cassette Pawl Spring by Raji Bentz

This works great and you need them as these little springs are very easy to lose. They are only needed for the now obsolete old design Campy bushings, but IMNSHO the old design bushings are better (albeit slightly heavier) than the new Campy design as they use larger bearings and better bearing preload adjustment. On the other hand, it is worth spending a lot of money for a nib that is essentially the same as cheap ballpoint pens.
