Hi,

When riding my Internally Routed synapse in recent weather I've noticed that it collects road gunk in the bottom bracket cable guide cavity. The result of this is unsurprisingly poor shifting performance.

the cable runs through the chainstay and out an unprotected hole in the end of it before running into the outer housing.

Wondering if anyone else has had this and found any way to improve the sealing (like by actually sealing the end of the chain stay with a boot or something)?
Do Nellyphants count?
