So you own a Canyon Grand Canyon AL and changed the boring old mechanical shifter? You got a nice set of Sram Etap or DI2? You need to cover the mecanical wire ports? Or the new DI2 cable?
For DI2 with front derailleur you will need a DI2 gromet ( SM-GM02 ) Most of the parts was printed in PETG, the Di2_Bottom_Gromet and Di2_TopLine was printed in TPU
Print this covers and you are all set.
