Can anyone tell me what these little rubber thingamabobs are for?
They are about 2cm long, split along the length and the opening at one end is inner cable sized whilst the opening at the other end is about 50% larger, but not wide enough for outer cable.


They came in the little bag of bits with my Giant Revolt but I can't work out what they are intended for. There aren't any already on the bike and I can't see anywhere where they might be used.
They're to stop cables rubbing on your frame
cable / head tube protectors?
I assume they're not gear cable inline adjustors.
I originally thought they might be cable/frame protectors but the bike has internally routed cables/hoses throughout.
The fact that the end openings are different sizes has thrown me. One end is ridged as well so I am wondering if they are supposed to be inserted somewhere (oo-er).
*ribbed inserts* <rubs thighs>
would they work at the point of insert/exit for the routed cables (not having an internally routed bike I don't know if this would work). though that would require more than 3 surely.

would that be feasible?

kcal wins!
My bike is not a TCR and it is not Di2 equipped. Maybe Giant are anticipating me upgrading in the future? It's highly unlikely but I admire their optimism.
