If you are talking your Chubby fork, this adapter is a K2 adapter on Ebay right now. The price is right.

For the rear, a mount could be welded on.

Post by: fyrstormer on October 18, 2010, 10:41:03 am: Are you sure those bolt holes are intended for use with a disc adaptor? I know some disc adaptors use them in addition to other mounting points, but unless yours are substantially beefier than mine are, they're not enough by themselves.

Ultimately, I ended up paying shovelon to weld a disc tab onto my 756 swingarm. Can't beat welding for shear strength (pun not intended).

Post by: coyotehunter on November 04, 2010, 06:53:59 pm: Possibly a stupid question, but I'm new to the world of discs...

Does the front bracket for the Chubby forks allow most any caliper to be mounted, or is a bracket specific to a manufacturer required? Planning to go with a front disc setup for Christmas and want to get all the info before wasting some money on something that won't fit.

Post by: Colin on November 05, 2010, 05:49:08 am: I'm not an expert as I don't have a Chubby fork, but I'm pretty certain that the disk caliper mounting holes on a Chubby are not to ISO standard, i.e. the modern standard.
Thus you need the 5994 part to adapt the fork to allow an ISO caliper to fit.
