ok, so, i am confused. listed below are the only bikes that this part 5996 will fit. my part is based intirely on part #5996. that is how i found this forum. that is why i am posting in this thread, K2 5996. i asumed that those of you who have been questioning the fitting had already looked at the posting below. there might be significant manufacturing reasons that k2 did not design a part for your application. there are front suspension forks out there that can only use a maximum of a 6" front disc brake rotor, there design cant take the stress of something bigger. maybe the same can be said for the CF swingarms, they might not be designed to have torsional forces at the drop-out location. i dont know. i have made a pretty cool rough copy of part 5996. if anyone would like one, let me know.

That would be sweet - Here's a good place to start.

looks like palm springs ca in the background. without a bike i wouldnt know where to begin. besides im no design engineer. and the part in the picture looks like it worked. do you not like that one? or is that someone elses bike?

 i purchased disc brakes for my bike because it looked like k2 had rear disc in mind when the bike was designed. the brake cable-guide bosses that are welded to the frame were double, one for cable with stops and one without for hose to pass through. thats on the frame, the fork just has the pass through hose type. so i figured there had to be some kind of adapter. i didnt know what it was called until i printed out the owners manual.

that's one of my 4500's, carbon crosslink and home made adapter.
made a several of them but only mounted a few - they've all worked without issue even on the aluminum legs.
the old verbiage on the process is in the 'How To's' near the top.  several have made their own and some old pics should/may be in picture galleries.

Yes my 4000 is a '98 model and my 4500 and OZ are technicaly the same as they use the same carbon rear arm, so Im not sure it will fit. The dropout shape looks different to me. A real shame as your finished artical looks and obviously works fantastic.
Am I right in saying all the models on the 5996 sheet have aluminium swing arms? Thats maybe where the worry over heat dispersion came from for the carbon arms.

i was looking at images on google of the 99' 4000 and it has a CF swingarm. the 5996 instructions say they work on all 99' 4000 models, so i would say no not all models that this part works on are just aluminum swingarm models. maybe k2 changed the dropouts in 99'

[racesrc]

i'm betting it doesn't matter what the material of your swingarm is for this part, it's a drop-out thing. certain bikes in certain years had this drop-out, wether it was predrilled like mine or not. CF or AL. i dont know why or if or if not k2 designed similar type parts for other models.

i really do hope that some of you can use this part, but to be quite honest, helping fellow cyclists would just be icing on the cake. i am just happier than a pig in $hit. it looks like it belongs on the bike and works so well. i have been really putting it through its paces listening and feeling for anything wrong and that has just not happened.

not the fork, DUH, the swingarm
