I am really sorry I haven't got it out to you yet. I don't own a car and all my tools are back in Maine. Getting to the shop so I can take it apart on a day that I am not subbing and not having to work there has proven quite difficult. I am working on it.
Again, my apologies.

no worries, it's not for me, mine works. just making sure you didn't send it out waiting for a received it message from me.

I am really sorry, but I will not be able to send it. Work has dried up the past month and I am sweating making rent. Also, I just can't seem to get to the damn shipping place (the swing arm is off). In the mean time a local MTB club just got organized that I can actually ride with, and I've missed out on over a month of Sunday's worth of riding. I am really sorry for disappointing everyone and not being able to keep my word. Maybe when in the late spring when the road rides pick back up and I have steady work again.

so i received the k2 part # 5996 in the mail friday, now i realize that a new part had to be made anyway. my part lines the caliper up perfectly to a 6" rotor, the k2 part must use a 5" or 5.5". using the stock k2 part makes my caliper run too far in towards the axle not using the outer part of the rotor. i never asked anyone who had that part what size rotor was used. so if any one out there is using the k2 part 5996 let me know what size your rotor is.

The K2 part would be for 140mm rotors. But, I believe the 74mm to 51mm mount adapter you have is for 140mm rotors. There is one for 160mm rotors. So, if you ever redesign the part it would make it more universal if you adjusted the design to mimic the K2 part in that manner.

It's been a long time discussing the K2 Part # 5996 disc brake adaptor. I am updating my 1999 K2 4000 bike and want to upgrade the rear brake to disc. Are there any adaptors out there or any engineering specs to reproduce. I have produced a mock -up that is very close dimensionally but want to be sure before I attempt to produce the adaptor set up for 160 mm disc for Avid BB-7 disc brake assembly. I have a cousin who owns a CNC shop and would help produce this part. Any help would be appreciated.

The K2 5996 adapter will not work with neither carbon fiber swing arm types (4000/5000 and 857/957).

I have one and it came with a 2002 Bumpy Monkey with the cantilever aluminum swing arm.

In addition to that, the 4000/5000 carbon swing arm dropout :

a) doesn't have any threaded holes in place so that the adapter could be secured to it
b) the ellipse shaped cutout in the dropout could prove challenging to match
c) to the radius of the 'flat' part of the dropout could prove challenging to match

I have been entertaining the idea of building an adapter for quite some time but the lack of time and proper machinery proved to be an issue...

One of the idea was to actually remove the dropouts altogether and replace them with new ones machined to include and ISO mount or posts as well provision for 142 through axle etc...

Thanks for reply. My bike has aluminum swing arm and is tapped for an adaptor #5996. The K2 bike website has vintage drawings for the bike that go back to 1999. I have tried to find out engineering specs for reproduction, but w/o success. Hoping someone has this adaptors that is shown in previous posts.

Fabricated disc brake adaptor for 1999 K2 4000 full suspension bike. Part was created on a CNC and can be created again for anyone interested.
