Hi there im just looking for information, I was given a set of bora ultra two dark label and i was wondering is it normal to have all black spokes in the front wheel except for one witch is silver,
And the rear wheel has 2 silver ones
im just wondering have they been repaired or is this standard thanks again
If someone has used Sapim straight-pulls, thinking they are the same (they're not, different dimensions and material though the dims difference is negligible) you will find them stamped "SAPIM" just on the shaft before it goes aero, at the head. If they look the same as the other spokes in the wheel and are silver, they're third party replacements, Campagnolo never used silver in Bora for the "standard" spokes. If the are round and heftier in the mid portion, they're the old balancing spokes that Campag don't use any more, having added mass into the rim instead, to do the same job.
If the wheels have been repaired, check carefully around the entry points of the spokes into the rim for "bulging" ... a small amount of outward bowing of the carbon at that point is normal but if there is a marked bulge, keep and eye on it - on older Boras (ie before 2015 models), it could be caused by a spoke being snagged, or something like that, in a crash, and a very high "pull" load being momentarily applied to the spoke, dragging the little load-spreading plate inside the rim down, very hard, into the "vee" so spreading the carbon. In 99% of cases it's OK but in a very few, you get cracks propogating away from the bulge.
Some repairers fail to get the spreader plates correctly aligned inside the rim (or even miss them out entirely) and that can also put a marked bulge the carbon. Again, keep an eye on the area if you see that (having verfied that the plate is a) there and b) aligned correctly). Misalignment, especially, can cause the rim wall to fail just "above" the entry point of the spoke.
