Looking at putting rigid forks on my 1997 Cannondale commuter mtb. It has old school Rockshox Indy forks at present which measure axle to crown (when unweighted) of 430mm, and 260mm steerer. Ahead Diatech headset. I want to get rid of the bounce and looking at perhaps carbon forks from Carbon Cycles around £100 or Salsa forks from Wiggle at £72.  Need studs for cantilever brakes. Will these fit and does anyone any have suggestions/ recommendations?
