Hi all, I just built up a Specialized Aethos and the 10R carbon frame is compatible with mechanical shifting. I installed a wireless groupset and now I have to deal with this hole at the bottom bracket region, where the shifting cables would exit the frame. The plastic rails for the cables need the cables to be kept in place and even though there were covers for every other hole in the frame, it looks like Specialized doesn’t have one for this (pretty big opening, in a sensible region, very near the road surface…).
I am thinking of covering it with clear frame protector, but maybe someone has some more insight and better solutions? Specialized sells full bikes with electronic groupsets using this frame, so I’m surprised there is no ready OEM solution for it. Might have to go to a Specialized dealer and take a look myself maybe…
Thanks in advance :)
I recommend to not cover this hole because it is important to have a drainage hole in case water enters the frame in heavy rain e.g. Most frames have a hole at the bottom bracket area for that reason.
Very good point. It just look big enough to also pick up a lot of dirt. The BB shells are pretty well sealed by their own, so maybe I follow your recommendation, thanks!
Ok, then how about a small screen or cotton ball to allow the water to seep out, but keeps the dirt/mud out. Not necessary, but one could do that.
I second this. Leave it open or you’re going to be constantly re-opening it to drain water.
