While there are a number of solutions for mounting Shimano's Di2 A Junction Box (SM-EW90 A/B), few are as sleek and unobtrusive as K-Edge's Di2 Junction Box Mount. Manufactured from stainless steel with a black oxide finish, this mount uses a headset spacer mounting system that allows it to be installed onto the fork steerer tube along with the rest of the headset spacers (compatible with 1 1/8" steerers/headset spacers). With a stack height of less than 1 mm (.9 mm), this mount can easily be added anywhere within your current stack of spacers. As the stainless steel mount is bendable, fit can be further dialed in by bending the mount to match the stem's angle, placing the junction box directly and discretely under the stem. The subtle black finish and small form factor, along with the fact that elastic bands and/or zip ties necessary on many other mounts are not needed, combine to make this one of the cleanest stem/steerer Junction A mounts available. At a mere 6.6 grams, it will also likely save weight over your current mounting solution. The Shimano Junction box shown in photos are for reference only, the junction box is not included. Please feel free to contact us with any fitment questions.
