|Both brand new campy binder bolt and i was careful to grease it well and didn not overtighten on a steel frame |
I noticed as it gets tighter the bolt bends - i think thats the cause
But i have no remedy
|maybe a frame problem...||dave|

|If the frame is old, someone before you may have overtightened the clamp on the frame and squeezed it together. The bolt shouldn't tighten enough to bend it.|
|Are you sure the seat post is the right size?||Dave Hickey|

|The only time I've had bolts bend is if the seat post is too small. Even a 27.0 in a 27.2 tube can enough to bend the bolt.|

|I have encountered the very same problem. First, I found that even with a verified 27.2 seatpost in a verified 27.2 seat tube the standard seat post binder bolt (19mm) was too long. It would tighten to the point where the two ends of the bolt met, and as I continued to tighten the bolt would eventually snap. This happened on a Litespeed Ultimate and a Look KG 243. I found that placing small washers in the ear holes of the seat tube binder allowed me to use the 19mm binder bolts without the bolts .
Second, I have replaced the Campy seat post binder bolts with generic cro-moly ones. They seem to hold up better than the Campy bolts...in fact, I have yet to break one of the generic ones. The Campy bolts seem more brittle, and two shops I have purchased the generic bolts from indicated they had the same problem with the Campy bolts.
