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

Marchisio sprockets for 8 speed and 9 speed have their origin in the former Junior line. As of 8/9 speed they also replace the former Aviotek sprockets. Aviotek is no longer in production.
