It is with deep regret that I must inform you that the company Marchisio Engineering SRL have ceased operating since they went into liquidation.
At the moment it is not clear if a successor will continue making the multi-compatible sprockets.
I would like to thank all customers who have supported Marchisio over many years.
My sale goes on until stock lasts.
Just two sprockets in a Marchisio MTK cassette have to fit the hub. All other sprockets are being connected to the hub by MTK adapters. At the same time the adapters make the distance between the sprockets appropriate to the levers. A brilliant solution that allows countless gearing ratios. This way some great conversion cassettes are possible as well.
