I've just purchased the last two available M20 brake drum/sprockets from a UK manufacturer.
One is for fitting to my own bike, the other is surplus...These are UK manufactured CNC machined replicas of the correct material and nice quality.
Price is £70 plus shipping if anybody needs one...Ian

Hello Ian,

I am very intersted in your spare M20 rear brake drum/ sprocket.

Is it still available. I hope to hear from you.

Regards,

Ian, if he's got a CNC programme written for them, why are they the last ?

I'm hearing lots of stories about pattern 16H sprockets shedding teeth. The difficulty is knowing who to trust.

Hi Rik...They are made in batches every so often..if and when they will be made again is a 'known unknown' as Donald Rumsfeldt would say..There are long periods of unavailability. These are good quality..I have used and sold them before....Ian

Hi Ian if there was enough interest from this forum maybe he would make a batch. I would take two.

Hi Terry..They seem to do a batch every so often but it is irregular.I'm not sure how many are made each time. I'll put up a posting to see if there is any interest and make some enquiries if there is sufficient response....Ian
