Tubeless/ Moto Guzzi Rims

[bonester]

Mate of mine bought a really nice Guzzi Lemans 2 that is dressed to look like a 1. Anywho it seems that it has been in an accident in the past and has an incorrect front wheel fitted. Anyone got a Lemans 2 wheel lying around? He wants to replace the brake discs with original ones and they don't fit the rim.
Another issue is that the rim had a Battleaxe with a tube fitted. The rim does not have 'tubeless' written on it and he wants to try fitting a tyre tubeless style. The current rim does not have a ridge for the bead to jump over when fitting. I thought I would show him what I meant by that ridge for tubeless and showed him two of my spare GT550 rims which do have 'tubeless' written on them. The rear rim has the ridge for the bead and the front doesn't! What gives? Thanks.
