Question to those who have done the conversion. Have just tried sigma pepperpots on front wheels and they don't clear the outer edge of the brake callipers. Have others rounded off the edge of the calliper to fit their sigma wheels.
I started this conversion but it seems there must be two different caliper types on a TP Magna? The ones I got at least would not clear the wheels. Somewhere in this group i think there is a picture of a conversion process but the calipers are are a different type. Maybe that helps.
I no longer have the calipers due to moving house and divesting much stuff ! I do though have a new set of Rotors.this is the thread where i put pics of the 'other' caliperhttp://www.bellett.net/forums/viewtopic.php?f=35&t=1890
