You've been running Di2 while you train on your road bike all winter and spring, but your riding group recently convinced to sign up for your first tri. Since you aren't ready to commit to a tri bike just yet, you're going to need to jockey some e-tubes around to approximate tri geometry for now. Shimano's TL-EW02 Di2 Wire Connecting Installation Tool will make your job easier, sliding into tight spaces on your frame to loosen and move the spaghetti-like e-tubes to their proper spots on your frame, freeing up more time for you to fine-tune your swim stroke.
Q & A
Di2 must have
