Hello there, my first post on this forum...have been lurking for while now
After finding this thread I felt compelled to post.
It appears I have exactly the frame as the OP (or had) It klien attitude comp from I believe '99 with (no internal cable routing). I got a crack through one of the dropouts, re-welded it & took it to a powder coater for a re-paint. I also decided it was time to upgrade most of the components including a rear disk as i had some unused Juicy 7's available.
I chose the adapted listed on torontocycles & had bad experience with it. The problem I have is that when the caliper is decently aligned, everthing is attached & working there just not enough clearance between the adapter & rotor. It's ridable but the clearance gets worse as you use the brake. This is because the adapter bends/flexs & eventually the clearance is zilch & the rotor is stuck on the adapter. I've had the straighten it out a few times now i haven't got a decent vise to do it so have been using a hammer & anvil .
I'm not here to slamm this adapter its just i'm still strugling with it so if anyone has any ideas I'd appreciate it. I'd also like to know if the OP decided on anything.
I would post some pictures below of mine but it says I need 2 posts.
