I currently have a Campy centaur 115.5mm bottom bracket on my ride that is built from slightly oversized titanium tubing (Habanero) with Centaur double cranks. Would a Phil 110.5mm work on this bike? 115.5mm PW's are hard to come by.
Thanks.


Centaur double spec is 111mm, the alternate wide chainline
option was 115.5.

You might measure the chainline and check that your front
changer is able to move 2mm+ farther inside before buying
that 110. Front changer adjustment range is your likely
sticking point in that application and the most likely
reason the builder used the 115.5 spindle.

Yes, Phil can be shifted laterally but buying the right part
is so much better than fudging later since they all cost the
same.

The 115 BB was for the Campy Triple. The narrower version was for the double. But the Campy Taper was unique. I suppose he could be talking about the ISO BB which is a toothed arrangement but that wasn't clear.
