Fork/Rotor Contact Problem   Message List  
Reply | Forward Message #430 of 2457 |

I`ve been building up my other Baron and its pretty close to being
finished, but I just ran into a problem I have not seen before. This
particular Baron is a standard Baron with a set of new Velocity
Thracian wheels on it. I just received a new set of Avid mechanical
disc brakes for it today, so I pulled the wheels and installed the
rotors on the hubs. I had no problem re-installing the rear wheel, but
when I installed the front wheel I found that the rotor rubs on the
fork. As far as I can tell, it looks like the fork is the problem.
This particular fork is a bit different than any other fork I have
seen on a Baron. It looks just like your average Baron disc brake fork
except that the dropouts are reversed. I`ve seen many Baron forks, but
this is the only one I`ve ever seen with reversed dropouts, although
they don`t seem to have anything to do with the problem. Actually, the
fork seems to have been built incorrectly, particularly the left fork
leg. The bend in the fork leg seems to curve inward sooner than it
should. Can someone with disc brakes on their Baron tell me how much
space there is between the front rotor and the left fork leg?

Hi ct, I have plenty of clearance between the disc and the dropout.....about 8mm. The problem is the outer edge of the disc touching the fork. A defective fork...

This may sound like a really dumb question, but are you sure it's a 160mm rotor? Dana Don Smith <airxxxwolf@...> wrote: Hi ct, I have plenty of clearance...

Already thought of that Dana....it`s definitely 160mm. John Foltz sent me a pic of his Baron which has the same Thracian wheels, and he probably has a good...

Hi Doug, After seing a photo of John Foltz`s fork and wheel(he is using the same wheels) it became obvious that I have a defective fork. A spacer between the...

A shim misses between hub and dropout. This shim is welded to the dropout and is 4mm thick. Without this shim the fork doesn't meet the International Standards...

Dries, I purchased 2 new Baron framesets in December 2003 that were supposedly 2002 models, but I think the fork I`m having the problem with may be older. I`ve...
