Some of you geared riders will know about the work that has been going on for the last 2 years on a way to fit an internal disc brake on to a schlumpf hub. The design journey has been catalogued on the Facebook Geared Chat group.
The “Brakefast” project was an open source design project lead by Martin Charrier and myself to design an adaptor to the hub that allows a brake to operate on the rim side of the gearbox and be internal to the frame. The project has had lots of helpers and supports, this is real a community project! Although I will say special thanks to Maksym Siegienczuk who found us the manufacturer.
The Schlumpf hub has always had a problem with the disc fitting on the KH moment/spirit cranks as it transferred the braking action through the gear mechanism so reducing it’s life. It also had additional installation problems.
The “Brakefast” adaptor is for the Schlumpf geared unicycle hub. This adaptor fits on to the left-hand hub flange and gives the Schlumpf hub an internal disc fitting. We have also found a relatively easy way to install a tab on the other side of the frame with the Brakefast tab adaptor
The design process was made interesting with the introduction to the market of the 32 hole carbon rim and finding out that the hubs had 2 different PCD’s.
Unicycle.com in the UK have agreed to finance a batch of these and are looking for people who would like to pre-order some. The product is on the website here, but we ask people to also express interest in an adaptor on the facebook group or contact me directly.
