K-Edge’s Ki2 Electronic Shifting kit combines a collection of their CNC’d pieces with the Shimano Di2 drivetrain parts. It’s available as either the full group with the battery, derailleurs and shifters and XTR cranks and brakes. Or, you can get just the electronic Di2 bits or send in your own Di2 parts and they retrofit it as necessary. Prices are posted after the break along with detail pix and more info…
The shift button pods are machined to fit the climber’s remote shift buttons and mount inline with Shimano’s brake lever clamps just like their mechanical shifters would. The button package includes the pods, buttons and electronics/wire harness. Currently, the auxiliary shift buttons are designed to plug into the regular shifters, so K-Edge hard solders the wires into the front wire harness. Word is the new Ultegra Di2 system will provide an appropriate click-connect solution. Along those lines, K-Edge will be working on an Ultegra Di2 kit, too.
The only thing required up front us their standard braze-on direct mount adapter clamp. It positions the front derailleur about 4mm more outboard than it would be on a road bike to compensate for the different chain line on mountain bikes. They’re working on an adapter for frames with direct mount front derailleurs. It’s best that you check with them before ordering to make sure it’ll work with your frame.
In the rear, they increased the spring tension at the B and P springs to mimic the chain tension that a standard XTR rear mech would provide.
It’s available in their five standard ano colors (black, gun metal, blue, red & gold). This orange is actually a custom color done up for this Niner to show off the system.
